Valuation and Taxation

PART 1

REAL AND PERSONAL PROPERTY

39-5-101.  Duties of assessor. 

            The assessor shall list all taxable real and personal property located within his county on the assessment date, other than that comprising the property and plant of public utilities.

39-5-102. When schedules required - nonresident owners listed. 

            (1) Ownership of real property shall be ascertained by the assessor from the records of the county clerk and recorder, and owners of real property shall not be required to file schedules listing the same; but any person having or claiming to have an undivided interest in any real property, or any inchoate, possessory, or equitable interest therein, or any other estate less than the fee, or any lien on any real property may file a schedule with the assessor, specifying such interest.

(2) When the ownership of any real or personal property cannot be ascertained by the assessor after due diligence, he may list such property under the legend "owner unknown".

(3) The assessor shall furnish annually by the first day of June to the executive director of the department of revenue a list of the names and addresses of all nonresidents of the state as shown by the assessor's records as of the previous assessment date to have owned real or personal property within the county. 

39-5-103. Property described. 

            In listing tracts or parcels of real property, the assessor shall identify the same by section, or part of a section, township, and range, and, if such part of a section is not a legal subdivision, then by some other description sufficient to identify the same. In listing town or city lots, he shall describe the same by number of lot and block, or otherwise, in accordance with the system of numbering or describing used by the town or city in which said lots are located.

39-5-103.5. Maps of parcels of land in the county. 

            (1) Prior to January 1, 1981, each assessor shall prepare and maintain full, accurate, and complete maps showing the parcels of land in his county. The maps shall include a master county index map, together with applicable township, section, and quarter-section maps, depending on density. Guidelines shall be established by the administrator to produce uniformity throughout the state. The guidelines shall include the definition of a parcel, the development of a parcel numbering system, map size, map scale, and suggestions for minimum information to be plotted.

(2) In fulfilling the duty imposed upon him by subsection (1) of this section, the assessor may employ other mapping resources or maps available to him.

39-5-104. Valuation of property. 

            Each tract or parcel of land and each town or city lot shall be separately appraised and valued, except when two or more adjoining tracts, parcels, or lots are owned by the same person, in which case the same may be appraised and valued either separately or collectively. When a single structure, used for a single purpose, is located on more than one town or city lot, the entire land area shall be appraised and valued as a single property.

39-5-104.5. Valuation of personal property. 

            (1) On and after January 1, 1996, personal property shall be valued as of the assessment date, and the tax shall apply for the full assessment year without regard to any destruction, conveyance, relocation, or change in tax status occurring after the assessment date. The owner of taxable personal property on the assessment date shall be responsible for the property tax assessed for the full property tax year without proration.

(2) Personal property tax obligations resulting from any conveyance, relocation, or change in tax status of the property during the property tax year that are not in the process of collection as of January 1, 1997, shall be waived, and the treasurer shall not commence any action to collect such obligations.

39-5-104.7. Valuation of real and personal property that produces
alternating current electricity from a renewable energy source.

          (1) (a) Except as provided in paragraph (b) of this subsection (1), on and after January 1, 2008, all real and personal property used to produce two megawatts or less of alternating current electricity from a renewable energy source shall be valued by the assessor in the county where the property is located in accordance with valuation procedures developed by the administrator.

          (b) The valuation requirements specified in paragraph (a) of this subsection (1) shall not apply to biomass energy facilities, geothermal energy facilities, small or low impact hydroelectric energy facilities, as defined in section 39-4-101 (2.7), solar energy facilities, or wind energy facilities, as those terms are defined in section 39-4-101.

          (2) In developing the valuation procedures specified in paragraph (a) of subsection (1) of this section, the administrator shall utilize the procedures adopted for determining the actual value of a renewable energy facility as specified in section 39-4-102(1) (e).

          (3) A taxpayer shall notify the taxpayer’s county assessor when the taxpayer installs real and personal property used to product two megawatts or less of alternating current electricity from a renewable energy source; except that, if the taxpayer obtains a building permit under the jurisdiction of a local government for the installation, the notification required n this subsection (3) shall not be necessary.

39-5-105. Improvements - water rights - valuation. 

            (1) Improvements shall be appraised and valued separately from land, except improvements other than buildings on land which is used solely and exclusively for agricultural purposes, in which case the land, water rights, and improvements other than buildings shall be appraised and valued as a unit.

(1.1) (a) (I) Water rights, together with any dam, ditch, canal, flume, reservoir, bypass, pipeline, conduit, well, pump, or other associated structure or device as defined in article 92 of title 37, C.R.S., being used to produce water or held to produce or exchange water to support uses of any item of real property specified in section 39-1-102 (14), other than for agricultural purposes, shall not be appraised and valued separately but shall be appraised and valued with the item of real property served as a unit.

(II) For purposes of this section, valuing the water rights and the item of real property served by the water rights "as a unit" means that any increase in value of the property served with water made available directly, or by exchange, by the use of any dam, ditch, pipeline, canal, flume, reservoir, bypass, conduit, well, pump, or other associated structure or device, as defined in article 92 of title 37, C.R.S., shall be included in the valuation of the real property served by the water rights.

(b) The general assembly finds and declares that the value of water rights, and any dam, ditch, pipeline, canal, flume, reservoir, bypass, conduit, well, pump, or other associated structure or device, as defined in article 92 of title 37, C.R.S., used or held to produce or exchange water, for taxation purposes, should be recognized as a contribution to the value of all of the interests in the entire property served thereby and that the separate valuation of such water rights could result in double taxation. The provision of this subsection (1.1) shall not be construed to exempt any water rights from taxation but shall be construed as setting forth procedures for the valuation thereof.

(2) and (3) Repealed.

39-5-106. Purchase of state land. 

            The equity in land purchased from the state under contract shall, during the term of such contract, be appraised and valued in the same manner as though held in fee by the purchaser, and any improvements on such land shall be appraised and valued in the same manner as other improvements.

39-5-107. Personal property schedule. 

            (1) All taxable personal property shall be listed on a form of schedule approved by the administrator and prepared and furnished by the assessor. Such schedule shall be so designed as to show the owner's name, address, social security number or federal employer identification number, and the location and general description of the owner's taxable personal property, divided into the various subclasses, and shall provide sufficient space for the furnishing of such information, derived from the books of account, records, or Colorado income tax returns of the owner of such property, as may be required by the assessor to determine the actual value of such property.

(2) There shall be subjoined to such schedule the following declaration:

     "I declare, under the penalty of perjury in the second degree, that this schedule, together with any accompanying exhibits or statements, has been examined by me and to the best of my knowledge, information, and belief sets forth a full and complete list of all taxable personal property owned by me, or in my possession, or under my control, located in .... county, Colorado, on the assessment date of this year; that such property has been reasonably described and its value fairly represented; and that no attempt has been made to mislead the assessor as to its age, quality, quantity, or value.
                                                                                                                        ........................ Owner
........................ Date                                                                             ....................... Agent"

39-5-108. Schedule sent to taxpayer - return. 

            As soon after the assessment date as may be practicable, the assessor shall mail or deliver one copy of the personal property schedule to the place of business or to the residence of each person known or believed to own taxable personal property located in the county, or to the agent of such person. Such person or his or her agent shall list in such schedule all taxable personal property owned by him or her, or in his or her possession, or under his or her control located in said county on the assessment date, attaching such exhibits or statements thereto as may be necessary, and shall sign and return the original copy thereof to the assessor no later than the April 15 next following. Exhibits and statements attached to the personal property schedule shall be deemed sufficient for the purposes of the schedule if such exhibits or statements clearly list the property, the cost of the property, and the date the property was acquired.

39-5-108.5. Furnished residential real property rental advertisements - information to be provided to the assessor - legislative declaration.

          (1) The general assembly hereby finds and declares that: (a) Each assessor is required by law to discover and assess taxable personal property in the assessor’s county and to provide each person known or believed to own taxable personal property in the county with a personal property schedule;

          (b) Each owner of taxable personal property is required by law to list the owner’s taxable personal property on the personal property schedule, and the receipt of a personal property schedule from the assessor provides notice to a property owner that the property owner may own taxable personal property, which helps to ensure that:

          (I) More property owners comply with state property tax laws;

          (II) The property tax burden is more fairly distributed; and

          (III) The amount of property tax revenues lost by local governments due to property owners’ lack of knowledge regarding the taxable status of certain personal property is minimized;

          (c) Personal property that is used to furnish residential real property is exempt from property taxation so long as it is not used for the production of income at any time, but generally becomes subject to taxation if the residential real property is offered for rent on a furnished basis or otherwise used for business purposes;

          (d) In certain areas of the state, a high proportion of residential real property is advertised for rent on a furnished basis directly by property owners or by real estate agents, property management companies, lodging companies, and internet and print-based listing services that act as agents for multiple property owners and advertise multiple properties for rent, and because the advertisements typically do not precisely identify the property offered for rent by address or the owner’s name:

          (I) It is difficult for each assessor to accurately identify which parcels of furnished residential real property are being offered for rent and to which owners of furnished residential real property the assessor should provide personal property schedules; and

          (II) This difficulty impairs the fairness and efficiency of the property tax system and reduces property tax collections by making it more likely that owners of furnished residential real property rented to others will, in some cases deliberately and in many other cases due to a lack of notice regarding state property tax laws, fail to pay property taxes due on personal property used to furnish the residential real property; and

          (e) It is therefore necessary and appropriate to require the owner of furnished residential real property or an agent of the owner who advertises the property for rent to provide identifying information regarding the property to the assessor of the county in which the property is located upon the request of the assessor made no more than twice during any year as specified in this section or as mutually agreed to by the assessor and the owner or agent pursuant to paragraph (b) of subsection (2) of this section.

          (2) (a) Upon the request of the assessor of any county or city and county made no more than twice during any year:

          (I) A property owner who advertises for rent furnished residential real property that is located within the county or city and county shall provide to the assessor a list that identifies each property so advertised by address; and

         (II) An agent who advertises for rent on behalf of a property owner furnished residential real property that is located within the county or city and county shall provide to the assessor a list that identifies each property so advertised by owner and address.

         (b) An assessor and a property owner or agent may mutually agree that the owner or agent shall annually provide to the assessor by a specified date the information that an assessor may require to be provided pursuant to paragraph (a) of this subsection (2).

          (3) For purposes of this section, agent means a real estate broker, as defined in section 12-61-101 (2) (a), C.R.S., a property management company, a lodging company, an internet web site listing service, a print-based listing service, or any other person that either separately or as part of a package of services advertises furnished residential real property in the state for rent on behalf of the owner of the property in exchange for compensation.

39-5-109. Inventory schedules - valuation. (Repealed) 

39-5-110. Property brought into state after assessment date - removal before next assessment date. 

            (1) Whenever any taxable personal property is brought from outside the state into any county of the state at any time after the assessment date in any year, the owner shall list the property on the personal property schedule sent to the taxpayer pursuant to section 39-5-108.

(2) If any taxable personal property located in the state on the assessment date or brought into the state at any time after the assessment date is removed from the state before the next following assessment date, the owner of the property shall not be relieved of any tax obligation with respect to the property as a result of the transfer of the property for the property tax year in which the transfer occurred.

(3) Repealed.

(4) Notwithstanding any other provision of this section, oil and gas drilling rigs shall be valued pursuant to section 39-5-113.3. 

39-5-111. Livestock, agricultural products - not valued, when. (Repealed)

39-5-112. Livestock - apportionment of value. (Repealed)

39-5-113. Movable equipment - apportionment of value. 

            (1) Any person owning any portable or movable equipment which is apt to be located or maintained in two or more counties of the state during any calendar year shall indicate in a statement accompanying his personal property schedule the kind and description and a serial number, if available, of such equipment, the counties in which such equipment is apt to be located or maintained, and the estimated period of time during the calendar year in which such equipment is apt to be so located and maintained.

(2) The assessor of the county in which such equipment is located on the assessment date shall determine its value and shall apportion such value between the counties affected and the school districts thereof, in the proportion that the periods of time during which such equipment may be located or maintained in such counties bear to the full calendar year. He shall furnish a copy of such valuation and apportionment to the owner of such equipment or to his agent and shall also transmit a copy thereof to the assessor of each county affected as his authority to list the apportioned value of such equipment on the assessment roll of his county. For purposes of making such apportionment, the valuation of the portable or movable equipment made by the assessor of the county of original assessment shall be used by all county assessors involved.

(3) If, subsequent to the making of such apportionment of value, any such equipment is removed to a county not initially included in such apportionment or if any such equipment is located or maintained in any county for a period of time different from that used in the initial apportionment, then an amended apportionment of value shall be requested by the assessor of any county so affected. Such assessor shall furnish a copy of such requested amended apportionment to the owner of such equipment or to his agent and shall also transmit a copy thereof to the assessor of each county affected, as his authority to list such reapportioned value on the assessment roll of his county. Failure of a county assessor to request such an amended apportionment shall permit the original apportionment of value to stand, and no other county assessor shall assess such equipment as is listed in the original apportionment for any period during the year of the original assessment. If such amended apportionment of value is received by any assessor after he has filed his annual abstract of assessment with the administrator, then either an abatement or an additional assessment shall be made, as the case may be.

(4) Repealed.

39-5-113.3. Oil and gas drilling rigs - apportionment of value

            (1) As soon after the assessment date as may be practicable, the assessor shall determine those oil or gas drilling rigs that were operating, stored, or maintained in the county during the preceding calendar year and shall mail or deliver two copies of a declaration to the place of business or drilling operation or to the residence of each person known or believed to own such rigs, or to the agent of such person. Such person or his agent shall list in such declaration all oil or gas drilling rigs owned by him, or in his possession, or under his control that were located in said county during the previous calendar year, attaching thereto the drilling logs of the respective rigs showing their various locations and corresponding dates. In addition, such person or his agent shall provide to the assessor of the first county in Colorado listed on each rig's log an inventory of that rig's equipment sufficient to determine a valuation for assessment. The original copy of the declaration shall be signed and returned to the assessor no later than the April 15 next following.

(2) The assessor, upon receiving such inventory and notification that his county was the first location of the rig in Colorado, shall determine its value and shall apportion such value between the counties in which the drilling rig was located during the preceding year and the districts thereof, in the proportion that the periods of time during which such equipment was located or maintained in such counties bear to the full calendar year. On or before June 15, the assessor shall furnish a copy of such valuation and apportionment to the owner of such equipment or to his agent and shall also transmit a copy thereof to the assessor of each county affected, together with a copy of the drilling log for that rig. For purposes of making such apportionment, the valuation of the oil or gas drilling rig made by the assessor of the first Colorado county on the log shall be used by all county assessors involved. In the subsequent counties, the assessor shall accept the returned declaration with the rig's name and location data as a proper filing.

(3) The values so apportioned shall be included in the affected counties' abstracts of assessment filed pursuant to section 39-5-123.

(4) This section shall apply to the apportionment of value of oil or gas drilling rigs and not the provisions of section 39-5-113.

(5) For purposes of this section "oil and gas drilling rigs" shall be defined by the property tax administrator pursuant to section 39-2-109 (1) (e), which definitions shall be uniform and consistent throughout the state. 

39-5-113.5. Works of art - apportionment of value. 

            (1) Any persons owning any works of art which are apt to be displayed in any county of the state during any calendar year shall indicate in a statement accompanying their personal property schedule the kind and description of such works of art and the estimated period of time during the calendar year in which such works of art are to be so displayed and shall provide to the assessor proof of exemption pursuant to the provisions of sections 39-3-123 and 39-26-102 (2.5). Failure to file a statement results in forfeiture of a claim for exemption in that calendar year.

(2) The assessor of the county in which such works of art are displayed shall determine its value in the proportion that the periods of time during which such works of art may be displayed bear to the full calendar year. He shall furnish a copy of such valuation to the owner of such works of art or to his agent. 

39-5-114. Unclassified property shown on schedule. 

            If any person owns, holds, or controls any kind or character of taxable personal property which is not specifically classified on the personal property schedule, he shall note such property therein, and such notation shall be held to be a sufficient description thereof for purposes of valuing the same, without further enumeration or description; but if the assessor so requests, such person shall disclose of what said property consists and its uses in detail. 

39-5-115. Taxpayer to furnish information - affidavit on mineral leases. 

            (1) At any time prior or subsequent to April 15 of each year, the assessor may request any person known or believed to own taxable property located in his county to furnish such information or to make available for examination such records as may be required by him to determine the actual value of such property.

(2) Within ten days after the execution of a mineral lease, a lessor shall file with the assessor an affidavit stating the annual net rental payable under such lease for the purposes of determining the actual value of such mineral interest where the income approach to appraisal is utilized by the assessor. Such affidavit shall constitute a private document and shall be available on a confidential basis as provided in section 39-5-120.

39-5-116. Failure to file schedule - failure to fully and completely disclose. 

            (1) If any person owning taxable personal property to whom one or more personal property schedules have been mailed, or upon whom the assessor or his deputy has called and left one or more schedules, fails to complete and return the same to the assessor by the April 15 next following, unless by such date such person has requested an extension of filing time as provided for in this section, the assessor shall impose a late filing penalty in the amount of fifty dollars or, if a lesser amount, fifteen percent of the amount of tax due on the valuation for assessment determined for the personal property for which any delinquent schedule or schedules are required to be filed. Any person who is unable to properly complete and file one or more of such schedules by April 15 may request an extension of time for filing, for a period of either ten or twenty days, which request shall be in writing and shall be accompanied by payment of an extension fee in the amount of two dollars per day of extension requested. A single request for extension shall be sufficient to extend the filing date for all such schedules which a person is required to file in a single county. Any person who fails to file one or more schedules by the end of the extension time requested shall be subject to a late filing penalty as though no extension had been requested. Further, if any person fails to complete and file one or more schedules by April 15 or, if an extension is requested, by the end of the requested extension, then the assessor may determine the actual value of such person's taxable personal property on the basis of the best information available to and obtainable by him and shall promptly notify such person or his agent of such valuation. Extension fees and late filing penalties shall be fees of the assessor's office. Penalties, if unpaid, shall be certified to the treasurer for collection with taxes levied upon the person's property.

(2) (a) If any person owning taxable personal property to whom two successive personal property schedules have been mailed or upon whom the assessor or his deputy has called and left one or more schedules fails to make a full and complete disclosure of his personal property for assessment purposes, the assessor, after notifying the person of his failure to make such a full and complete disclosure and allowing such person ten days from the date of notification to comply, shall, upon discovery, determine the actual value of such person's taxable property on the basis of the best information available to and obtainable by him and shall promptly notify such person or his agent of such valuation. The assessor shall impose a penalty in an amount of up to twenty-five percent of the valuation for assessment determined for the omitted personal property. Penalties, if unpaid, shall be certified to the treasurer for collection with taxes levied upon the person's personal property. A person fails to make a full and complete disclosure of his personal property pursuant to this paragraph (a) if he includes in a filed schedule any information concerning his property which is false, erroneous, or misleading or fails to include in a schedule any taxable property owned by him.

(b) Any person who makes full and complete disclosure on the first personal property schedules issued to him on or after August 1, 1987, shall not be assessed a penalty for property previously omitted from the assessment rolls under this article.

(c) Any person subject to paragraph (a) of this subsection (2) shall have the right to pursue the administrative remedies available to taxpayers under this title, dependent upon the basis of his claim.

39-5-117. Property improvements destroyed after assessment date. 

            Whenever any improvements are destroyed or demolished subsequent to the assessment date in any year, it is the duty of the owner thereof or the owner's agent to promptly notify the assessor of such destruction or demolition and the date upon which the same occurred. In all such cases, such improvements shall be valued by the assessor at the proportion of its valuation for the full calendar year that the period of time in such year prior to its destruction or demolition bears to the full calendar year. Failure of the owner thereof or of the owner's agent to so notify the assessor prior to the date taxes are levied shall be considered a waiver, and no proportionate valuation by the assessor shall then be required.

39-5-118. Failure to receive schedule - validity of valuation. 

            No determination of the actual value of any taxable personal property made by the assessor shall be rendered invalid by reason of his failure to secure or receive the personal property schedule required to be completed and returned to him prior to his determination of such value.

39-5-119. Refusal to answer - court order. 

            Whenever any person refuses to be interviewed by the assessor or his deputy or refuses to answer any pertinent questions relative to taxable property owned by him, or in his possession, or under his control, then, in the discretion of the district court having jurisdiction in the county and upon affidavit of the assessor or his deputy showing such refusal to be interviewed or to answer such questions, such person shall be cited before such court and shall be required by the court then and there to submit to such interview and to answer such questions. All costs of such proceedings shall be assessed by the court against such person, and judgment and execution shall be entered therefor as in other civil cases.

39-5-120. Tax schedules endorsed and filed - availability for inspection. 

            All personal property schedules and exhibits or statements attached thereto returned to or secured by the assessor shall be endorsed with the name of the person whose taxable personal property is listed therein and shall be filed in either alphabetical or numerical order and retained for a period of six years, after which time they may be destroyed. Such schedules and accompanying exhibits or statements shall be considered private documents and shall be available on a confidential basis only to the assessor and the employees of his office, the treasurer and the employees of his office, the annual study contractor hired pursuant to section 39-1-104 (16) and his employees, the executive director of the department of revenue and the employees of his office, the administrator and the employees of his office, and the person whose taxable personal property is listed therein. Such exhibits or statements shall be available on a confidential basis to the board and the county board of equalization when information contained in such documents is pertinent to an appeal or protest.

39-5-121. Notice of valuation - legislative declaration. 

            (1) (a) (I)  No later than May 1 in each year, the assessor shall mail to each person who owns land or improvements a notice setting forth the valuation of such land or improvements. For agricultural property, the notice shall separately state the actual value of such land or improvements in the previous year, the actual value in the current year, and the amount of any adjustment in actual value. For all other property, the notice shall state the total actual value of such land and improvements together in the previous year, the total actual value in the current year, and the amount of any adjustment in total actual value. The notice shall not state the valuation for assessment of such land or improvements or combination of land and improvements. Based upon the classification of such taxable property, the notice shall also set forth either the ratio of valuation for assessment to be applied to said actual value of all taxable real property other than residential real property prior to the calculation of property taxes for the current year or the projected ratio of valuation for assessment to be applied to said actual value of residential real property prior to the calculation of property taxes for the current year and that any change or adjustment of the projected ratio of valuation for assessment for residential real property shall not constitute grounds for the protest or abatement of taxes. With the approval of the board of county commissioners, the assessor may include in the notice an estimate of the taxes that shall be owed for the current property tax year. If such estimate is included, the notice shall clearly state that the tax amount is merely an estimate based upon the best available information. The notice shall state, in bold-faced type, that the taxpayer has the right to protest any adjustment in valuation but not the estimate of taxes if such an estimate is included in the notice, the classification of the property that determines the assessment percentage to be applied, and the dates and places at which the assessor will hear such protest. Except as otherwise provided in subparagraph (II) of this paragraph (a), such notice shall also set forth the following: That, to preserve the taxpayer's right to protest, the taxpayer must notify the assessor either in writing or in person of the taxpayer's objection and protest; that such notice must be delivered, postmarked, or given in person no later than June 1; and that, after such date, the taxpayer's right to object and protest the adjustment in valuation is lost. The notice shall be mailed together with a form that, if completed by the taxpayer, allows the taxpayer to explain the basis for the taxpayer's valuation of the property. Such form may be completed by the taxpayer to initiate an appeal of the assessor's valuation. However, in accordance with section 39-5-122 (2), completion of this form shall not constitute the exclusive means of appealing the assessor's valuation. For the years that intervene between changes in the level of value, if the difference between the actual value of such land or improvements in the previous year and the actual value of such land or improvements in the intervening year as set forth in such notice constitutes an increase in actual value of more than seventy-five percent, the assessor shall mail together with the notice an explanation of the reasons for such increase in actual value.

         (II)  For the city and county of Denver only, if the city and county of Denver elects to use the pilot alternate protest procedure established in section 39-5-122.8, the notice mailed pursuant to subparagraph (I) of this paragraph (a) shall state that, to preserve the taxpayer's right to object and protest, the taxpayer must notify the board of county commissioners in writing of the taxpayer's objection and protest; that such notice must be delivered or postmarked no later than November 15 of the year in which the notice of valuation was mailed; and that after such date, the taxpayer's right to object and protest the adjustment in valuation is lost.

(b) (I) Commencing as provided in subparagraph (II) of this paragraph (b), the notice of valuation for the first year of each reassessment cycle that is mailed to each person who owns land or improvements pursuant to paragraph (a) of this subsection (1) shall include, in addition to the information specified in paragraph (a) of this subsection (1), an itemized listing of the land and improvements and the characteristics that are germane to the value of such land and improvements.

(II) In a county with a population in excess of fifty thousand people, the information specified in subparagraph (I) of this paragraph (b) shall be included in notices of valuation mailed on or after January 1, 2001. In a county with a population of twenty-five thousand people or more but not more than fifty thousand people, the information specified in subparagraph (I) of this paragraph (b) shall be included in notices of valuation mailed on or after January 1, 2003. In a county with a population of less than twenty-five thousand people, the information specified in subparagraph (I) of this paragraph (b) shall be included in notices of valuation mailed on or after January 1, 2005.

(1.2) A notice of valuation included with the tax bill shall fulfill the requirements of subsection (1) of this section. The general assembly hereby finds and declares that the notice procedure set forth in this subsection (1.2) facilitates the efficient and economic operation of local governments, consistent with the expressed purpose of section 20 of article X of the state constitution to reasonably restrain most the growth of government, and still fulfills the purposes of section 20 (8) (c) of said article X in the intervening year of each reassessment cycle when there is no change in value for the property in such year.

(1.5) (a) (I)  Except as otherwise provided in sub-subparagraph (A) of subparagraph (II) of this paragraph (a), no later than June 15 in each year, the assessor shall mail to each person who owns taxable personal property a notice setting forth the valuation of the personal property. The notice shall state the actual value of such personal property in the previous year, the actual value in the current year, and the amount of any adjustment in actual value. The notice shall not state the valuation for assessment of the personal property. The notice shall also set forth the ratio of valuation for assessment to be applied to said actual value prior to the calculation of property taxes for the current year. With the approval of the board of county commissioners, the assessor may include in the notice an estimate of the taxes that shall be owed for the current property tax year. If such an estimate is included, the notice shall clearly state that the tax amount is merely an estimate based upon the best available information. The notice shall state, in bold-faced type, that the taxpayer has the right to protest any adjustment in valuation but not the estimate of taxes if such an estimate is included in the notice, and the dates and places at which the assessor will hear protests. Except as otherwise provided in subsection (II) of this paragraph (a), the notice shall also set forth the following: To preserve the taxpayer's right to protest, the taxpayer must notify the assessor either by mail or in person of the taxpayer's objection and protest; that the notice must be postmarked or physically delivered no later than June 30; and that, after such date, the taxpayer's right to object and protest the adjustment in valuation is lost. The notice shall be mailed together with a form that, if completed by the taxpayer, allows the taxpayer to explain the basis for the taxpayer's valuation of the property. The form may be completed by the taxpayer to initiate an appeal of the assessor's valuation. However, in accordance with section 39-5-122 (2), completion of this form shall not constitute the exclusive means of appealing the assessor's valuation.

           (II)  For the city and county of Denver only, if the city and county of Denver elects to use the pilot alternate protest procedure established in section 39-5-122.8, the notice required pursuant to subparagraph (I) of this paragraph (a) shall be modified as follows:

           (A)  The assessor shall mail to each person who owns taxable personal property the notice setting forth the valuation of the personal property no later than July 15 each year; and

           (B)  The notice shall state that, to preserve the taxpayer's right to object and protest, the taxpayer must notify the board of county commissioners in writing of the taxpayer's objection and protest; that such notice must be delivered or postmarked no later than November 15 of the year in which the notice of valuation was mailed; and that after such date, the taxpayer's right to object and protest the adjustment in valuation is lost.

(1.7)  Notwithstanding any other provision of law, a taxpayer may request to receive by electronic transmission the notices of valuation required by subsections (1) and (1.5) of this section. The taxpayer shall submit along with the request an electronic address to which the assessor may send future notices of valuation. The assessor, upon receipt of such request by a taxpayer to receive notices of valuation electronically, may send all future notices of valuation by electronic transmission to the electronic address supplied by the taxpayer; except that, if a taxpayer subsequently requests to cease the electronic transmission of such notices and requests to receive future notices of valuation by mail, the assessor shall comply with the request. Failure of a taxpayer to receive the electronic notice of valuation shall not preclude collection by the treasurer of the amount of taxes due from and payable by the taxpayer.

(2) (a) The assessor shall, no later than August 25 of each year, notify each taxing entity subject to the provisions of section 29-1-301, C.R.S., the division of local government, and the department of education of the total valuation for assessment of land and improvements within the entity and shall also report: The amount of the total valuation for assessment attributable to annexation or inclusion of additional land, and the improvements thereon, and personal property connected therewith, within the taxing entity for the preceding year; the amount attributable to new construction and personal property connected therewith, as defined by the administrator in manuals prepared pursuant to section 39-2-109 (1) (e), within the taxing entity for the preceding year; the amount attributable to increased volume of production for the preceding year by a producing mine if said mine is wholly or partially within the taxing entity and if such increase in volume of production causes an increase in the level of services provided by the taxing entity; and the amount attributable to previously legally exempt federal property that becomes taxable if such property causes an increase in the level of services provided by the taxing entity.

(b) In addition to the information specified in paragraph (a) of this subsection (2), the assessor shall, no later than August 25 of each year, notify each taxing entity except school districts of the total actual value of all real property within the taxing entity and the total actual value of all real property within the taxing entity from construction of taxable real property improvements, minus destruction of similar improvements, and additions to, minus deletions from, taxable real property, in accordance with the manner prescribed by the administrator in manuals prepared pursuant to section 39-2-109 (1) (e).

39-5-121.5. Valuation - inspection of data by taxpayers. 

            At the written request of any taxpayer or any agent of such taxpayer and subject to such confidentiality requirements as provided by law, the assessor shall, within seven working days after receipt of said request, make available to the taxpayer or agent the data used by the assessor in determining the actual value of any property owned by such taxpayer. At the assessor's election, the assessor may either mail, fax, or send by electronic transmission to the address, phone number, or electronic address supplied by said taxpayer or agent such data. Such data shall include but shall not be limited to the data derived from the declarations filed pursuant to the provisions of article 14 of this title and confidential data, provided that such confidential data shall be presented in such a manner that the source cannot be identified. Upon receipt of such request, the assessor shall notify the taxpayer or agent of the estimated cost of providing such information, payment of which shall be made prior to providing such information. Upon providing such information, the assessor may include a bill for the reasonable cost above the estimated cost and up to the statutory maximum which shall be due and payable upon receipt by the taxpayer or agent.

39-5-122. Taxpayer's remedies to correct errors. 

            (1) (a)  Except as otherwise provided in paragraph (b) of this subsection (1), on or before May 1 of each year, the assessor shall give public notice in at least one issue of a newspaper published in his or her county that, beginning on the first working day after notices of adjusted valuation are mailed to taxpayers, the assessor will sit to hear all objections and protests concerning valuations of taxable real property determined by the assessor for the current year; that, for a taxpayer's objection and protest to be heard, notice must be given to the assessor; and that such notice must be postmarked, delivered, or given in person by June 1. The notice shall also state that objections and protests concerning valuations of taxable personal property determined by the assessor for the current year will be heard commencing June 15; that, for a taxpayer's objection and protest to be heard, notice must be given to the assessor; and that such notice must be postmarked or physically delivered by June 30. If there is no such newspaper, then such notice shall be conspicuously posted in the offices of the assessor, the treasurer, and the county clerk and recorder and in at least two other public places in the county seat. The assessor shall send news releases containing such notice to radio stations, television stations, and newspapers of general circulation in the county.

         (b)  For the city and county of Denver only, if the city and county of Denver elects to use the pilot alternate protest procedure established in section 39-5-122.8, the notice required pursuant to paragraph (a) of this subsection (1) shall be modified to state that the city and county of Denver has elected to use the pilot alternate protest procedure established in section 39-5-122.8; that all objections and protests will be determined by the board of county commissioners in accordance with the protest procedures set forth in section 39-5-122.8; that, to preserve the taxpayer's right to object and protest, the taxpayer must notify the board of county commissioners in writing of the taxpayer's objection and protest; that such notice must be delivered or postmarked no later than November 15 of the year in which the notice of valuation was mailed; and that after such date, the taxpayer's right to object and protest the adjustment in valuation is lost.

(2) If any person is of the opinion that his or her property has been valued too high, has been twice valued, or is exempt by law from taxation or that property has been erroneously assessed to such person, he or she may appear before the assessor and object, complete the form mailed with his or her notice of valuation pursuant to section 39-5-121 (1) or (1.5), or file a written letter of objection and protest by mail with the assessor's office before the last day specified in the notice, stating in general terms the reason for the objection and protest. Reasons for the objection and protest may include, but shall not be limited to, the installation and operation of surface equipment relating to oil and gas wells on agricultural land. Any change or adjustment of any ratio of valuation for assessment for residential real property pursuant to the provisions of section 39-1-104.2 shall not constitute grounds for an objection. If the form initiating an appeal or the written letter of objection and protest is filed by mail, it shall be presumed that it was received as of the day it was postmarked. If the form initiating an appeal or the written letter of objection and protest is hand-delivered, the date it was received by the assessor shall be stamped on the form or letter. As stated in the public notice given by the assessor pursuant to subsection (1) of this section, the taxpayer's notification to the assessor of his or her objection and protest to the adjustment in valuation must be delivered, postmarked, or given in person by June 1 in the case of real property. In the case of personal property, the notice must be postmarked or physically delivered by June 30.  All such forms and letters received from protesters shall be presumed to be on time unless the assessor can present evidence to show otherwise. The county shall not prescribe the written form of objection and protest to be used. The protester shall have the opportunity on the days specified in the public notice to present his or her objection in writing or protest in person and be heard, whether or not there has been a change in valuation of such property from the previous year and whether or not any change is the result of a determination by the assessor for the current year or by the state board of equalization for the previous year. If the assessor finds any valuation to be erroneous or otherwise improper, the assessor shall correct the error. If the assessor declines to change any valuation that the assessor has determined, the assessor shall state his or her reasons in writing on the form described in section 39-8-106, shall insert the information otherwise required by the form, and shall mail two copies of the completed form to the person presenting the objection and protest so denied on or before the last regular working day of the assessor in June in the case of real property and on or before July 10 in the case of personal property; except that, if a county has made an election pursuant to section 39-5-122.7 (1), the assessor shall mail the copies on or before the last working day of the assessor in August in the case of both real and personal property.

(3) Any person whose objection and protest has been denied in writing by the assessor may appeal to the county board of equalization in the manner provided in article 8 of this title.

(4) The assessor shall continue his hearings from day to day until all objections and protests have been heard, but all such hearings shall be concluded by June 1 in the case of real property and July 5 in the case of personal property.

(5) (a) Any written statement given by any assessor which consists only of a denial of any objection and protest or which consists of a statement referring to compliance by the county with the requirements of valuation for assessment study shall not be sufficient to satisfy the requirements of subsection (2) of this section concerning the statement of reasons why an objection and protest is denied.

(b) Any information presented by the taxpayer regarding the value of his property shall be considered by the assessor in determining whether an adjustment in value is warranted.

39-5-122.1. Appeal from illegal increase in valuation of property resulting from order of state board. (Repealed)

39-5-122.5. Taxpayer's remedies - property tax credit for incorrect valuations used for property tax levied in 1987 for collection in 1988. (Repealed)

39-5-122.7. Alternate protest and appeal procedure for specified counties. 

            (1) The governing body of any county may, at the request of the assessor, elect to use an alternate protest and appeal procedure to determine objections and protests concerning valuations of taxable property. The election shall not be made unless the assessor has requested the use of the alternative protest and appeal procedure. The election shall be made on or before May 1 of each year and shall be effective for all objections and protests concerning valuations of taxable property for the year. The governing body of the county shall provide notice of the election to the board of assessment appeals and to the district court in such county.

(2) In the event that a county elects to follow an alternative protest and appeal procedure as authorized by subsection (1) of this section, the assessor shall issue any written determination regarding the objection and protest by the date specified in section 39-5-122 (2).

(3) For purposes of this section, "county" shall include a city and county.

39-5-122.8.  Pilot alternate protest procedure - city and county of Denver - repeal.

           (1)  At the request of the assessor, the governing body of the city and county of Denver may elect to use the pilot alternate protest procedure described in subsection (2) of this section to determine objections and protests concerning valuations of taxable property rather than use other provisions of this article. The election shall not be made unless the assessor has requested the use of an alternate protest procedure. The election shall be made on or before May 1 and shall be effective for all objections and protests concerning valuations of taxable property for that year and for all future years until the governing body elects not to follow the pilot alternate protest procedure or this section is repealed pursuant to subsection (3) of this section. A governing body that elects not to follow the pilot alternate protest procedure, after previously electing to follow such procedure, must do so on or before March 1. The governing body of the city and county of Denver shall provide notice of an election pursuant to this subsection (1) to the board of assessment appeals and to the district court in such county.

          (2) (a)  The city and county of Denver shall amend the notices required by sections 39-5-121 and 39-5-122 to provide notice that all objections and protests concerning valuation of taxable property shall be determined in accordance with this section.

          (b)  If any taxpayer is of the opinion that his or her property has been valued too high, has been twice valued, or is exempt by law from taxation or that the property has been erroneously assessed to such person, the taxpayer may file a written objection and protest with the board of county commissioners by delivering or mailing the written objection and protest no later than November 15 of the year in which the notice of valuation was mailed.

          (c)  Except as otherwise provided in paragraph (d) of this subsection (2), no decision on any written objection and protest concerning valuation of taxable property shall be made by the board of county commissioners unless a hearing is held thereon, at which hearing the assessor and the taxpayer or the taxpayer's authorized representative shall have the opportunity to be present. The board may appoint independent referees who are experienced in property valuation to conduct the hearing on behalf of the board, to make findings, and to submit recommendations to the board for its final decision. All decisions shall be mailed to the taxpayer or the taxpayer's authorized representative within five business days after the date on which such decision is rendered. If requested by the board of county commissioners, the taxpayer or the taxpayer's authorized representative shall be present at a hearing held pursuant to this paragraph (c) and shall produce information to support the written objection and protest. In the event the board of county commissioners requests the taxpayer or the taxpayer's authorized representative to be present at a hearing, the board of county commissioners shall provide at least thirty days' notice of the hearing, unless the taxpayer or the taxpayer's authorized representative requests a hearing at an earlier date. The board of county commissioners shall provide written notice of the hearing by certified mail, and such written notice shall contain the date, time, and place of the hearing. Upon request of the taxpayer or the taxpayer's authorized representative, the board of county commissioners may reschedule the hearing. If the taxpayer or the taxpayer's authorized representative fails to be present at the hearing when requested by the board of county commissioners, absent good cause, the board of county commissioners shall dismiss the written objection and protest, and the taxpayer or the taxpayer's authorized representative shall not have the right to appeal the dismissal.

          (d)  Upon authorization by the board of county commissioners, the assessor may review written objections and protests concerning valuation of taxable property and settle by written mutual agreement any such written objection and protest. Any reduction agreed upon and settled pursuant to this paragraph (d) is not subject to the requirements of paragraph (c) of this subsection (2).

          (e)  Every written objection and protest concerning the valuation of taxable property shall be acted upon pursuant to the provisions of this section by the board of county commissioners or the assessor, as appropriate, within six months of the date of filing such petition.

          (f)  If the board of county commissioners grants an objection and protest, in whole or in part, the assessor shall adjust the valuation accordingly; but, if the objection and protest is denied, in whole or in part, the taxpayer or the taxpayer's authorized representative may appeal the valuation set by the assessor or, if the valuation is adjusted as a result of a decision of the board of county commissioners, may appeal the adjusted valuation to the board of assessment appeals or to the Denver district court for a trial de novo, or the taxpayer may submit the case to arbitration pursuant to the provisions of section 39-8-108.5. Such appeal or submission to arbitration shall be taken no later than thirty days after the date such denial is mailed pursuant to paragraph (c) of this subsection (2).

          (g)  If the board of county commissioners does not issue a written decision on an objection or protest for valuation of taxable property before December 1 of the year in which the notice of valuation was mailed, the taxpayer's written objection and protest shall be deemed to be a petition for abatement or refund and shall be determined in accordance with section 39-10-114. If the board of county commissioners, pursuant to section 39-10-114 (1), or the property tax administrator, pursuant to section 39-2-116, denies the petition for abatement or refund of taxes in whole or in part, the taxpayer or the taxpayer's authorized representative may appeal to the board of assessment appeals or to the Denver district court for a trial de novo, or may submit the case to arbitration pursuant to section 39-8-108.5. Such appeal or submission to arbitration shall be taken no later than thirty days after the entry of any such decision.

          (3)  This section is repealed, effective December 31, 2018.

39-5-123. Abstract of assessment or amended abstract of assessment. 

            (1) (a) Upon conclusion of hearings by the county board of equalization, as provided in article 8 of this title, the assessor shall complete the assessment roll of all taxable property within the assessor's county, and, no later than August 25 in each year or no later than November 21 in each year in any county that has made an election pursuant to section 39-5-122.7, the assessor shall prepare therefrom three copies of the abstract of assessment and in person, and not by deputy, shall subscribe his or her name, under oath, to the following statement, which shall be a part of such abstract: "I, .............., the assessor of .............. county, Colorado, do solemnly swear that in the assessment roll of such county I have listed and valued all taxable property located therein and that such property has been assessed for the current year in the manner prescribed by law and that the foregoing abstract of assessment is a true and correct compilation of each schedule.

     ..................."

(2) The assessor shall file two copies of the abstract of assessment with the administrator, and, appended thereto, the assessor shall also file the aggregate valuation for assessment of all taxable property in the county, each municipality, and each school district within the county, by classes and subclasses, on a form prescribed by the administrator.

(3) Along with the abstract of assessment, the assessor shall file with the property tax administrator information relating to the valuation for assessment for residential real property, including new construction, increased volume of mineral and oil and gas production, and any other data determined by the administrator as necessary to determine the valuation for assessment for such property.

39-5-124. Property tax administrator to examine abstract. 

            (1) When the abstract of assessment has been subscribed and sworn to by the assessor and by the chairman of the board of county commissioners, the assessor shall transmit two copies thereof to the administrator and shall retain the third copy for endorsement of the tax warrant thereon.

(2) Upon receipt of such abstract, the administrator shall examine the same without delay and, if it is found correct as to form, shall certify such fact to the assessor, and such certification shall be conclusive evidence of the fact, time, and place of filing such abstract. If such abstract is found incorrect as to form, the administrator shall return the same to the assessor for correction.

39-5-125. Omission - correction of errors. 

            (1) Except as otherwise provided in subsection (3) of this section, whenever it is discovered that any taxable property has been omitted from the assessment roll of any year or series of years, the assessor shall immediately determine the value of such omitted property and shall list the same on the assessment roll of the year in which the discovery was made and shall notify the treasurer of any unpaid taxes on such property for prior years.

(2) Omissions and errors in the assessment roll, when it can be ascertained therefrom what was intended, may be supplied or corrected by the assessor at any time before the tax warrant is delivered to the treasurer or by the treasurer at any time after the tax warrant has come into his hands.

(3) If taxable personal property that has been omitted from the assessment roll of any year or series of years is discovered due to a property owner or an agent of a property owner who advertises for rent furnished residential real property providing information to the assessor pursuant to section 39-5-108.5(2), the assessor shall not notify the treasurer of any unpaid taxes on the taxable personal property for prior years and the property owner or agent shall not be liable for any such unpaid taxes for prior years.

39-5-126. Wrongful return by assessor. 

            Whenever any assessor willfully and knowingly omits any taxable property in his county from the assessment roll, or willfully and knowingly values any taxable property in his county contrary to the manner prescribed by law, and willfully and knowingly subscribes and swears to an abstract of assessment reflecting such omissions and containing such unlawful valuations, he is guilty of perjury in the second degree and, upon conviction thereof, shall be punished according to law.

39-5-127. Correction of assessments. 

            Whenever the state board of equalization makes any change in the abstract of assessment of any county or orders an increase or decrease in the valuation of any class or subclass of property located therein, the assessor shall make the necessary changes in the abstract of assessment of the next succeeding taxable year required to carry out such order; except that, whenever the state board of equalization changes the valuation of any class or subclass of property pursuant to section 39-9-103 (7), the assessor shall make the necessary changes in the abstract of assessment of the current taxable year required to carry out such order.

            (1) No later than August 25 of each year, the assessor shall certify to the department of education, to the clerk of each town and city, to the secretary of each school district, and to the secretary of each special district within the assessor's county the total valuation for assessment of all taxable property located within the territorial limits of each such town, city, school district, or special district and shall notify each such clerk, secretary, and board to officially certify the levy of such town, city, school district, or special district to the board of county commissioners no later than December 15. The assessor shall also certify to the secretary of each school district the actual value of the taxable property in the district.

            As soon as practicable after the requisite taxes for the year have been levied but in no event later than January 10 of each year, the assessor shall deliver the tax warrant under his hand and official seal to the treasurer, which shall be made readily available to the general public during the collection year in a convenient location in the courthouse. The assessor shall retain one or more true copies thereof, which shall be made readily available to the general public during the collection year in a convenient location in the courthouse. Such tax warrant shall set forth the assessment roll, reciting the persons in whose names taxable property in the county has been listed, the class of such taxable property and the valuation for assessment thereof, the several taxes levied against such valuation, and the amount of such taxes extended against each separate valuation. At the end of the warrant, the aggregate of all taxes levied shall be totaled, balanced, and prorated to the several funds of each levying authority, and the treasurer shall be commanded to collect all such taxes.

39-5-130. Informality not to invalidate. 

            No informality in complying with the requirements of section 39-5-129 shall render any proceedings for the collection of taxes invalid.

39-5-131. Certification and valuation of pollution control property. (Repealed) 

39-5-132. Assessment and taxation of new construction. 

            (1) The general assembly hereby finds and declares that it is a matter of statewide concern that revenues from property taxes on newly constructed buildings may need to be put to special use in order to accommodate the capital needs resulting from such new construction, especially to accommodate the capital needs of the public schools in this state. The general assembly further declares that it is essential that such revenue be available as soon as possible after the time such new construction is put to use. The general assembly further finds and declares that the board of county commissioners is the appropriate governmental unit to determine the extent of the growth within the county and the finding of severe growth impact shall be at the sole discretion of the board.

(2) (a) (I) (A) If the board of county commissioners determines that a county is becoming severely impacted by residential growth, the board of county commissioners shall make a finding of severe growth impact based upon the rate of increase in the county of the number of residential units being constructed within the county and an increase in pupil enrollment in school districts within the county such that at least one school district in the county meets the growth criteria described in sub-subparagraph (E) of this subparagraph (I), and other factors which indicate patterns of growth and growth impact, and shall, on or before January 1, resolve to implement the assessment and levy procedures required under this section. When a board of county commissioners makes such resolution, the provisions of this section shall apply countywide notwithstanding any law to the contrary. The board of county commissioners shall not make a finding of severe growth impact unless the number of residential units in the county will increase by over two percent during the county's current fiscal year. The board of county commissioners may negotiate with taxing authorities in the county to provide the costs of implementing the assessment and levy procedures required under this section. Notwithstanding any other provision of law to the contrary, any such taxing authority is hereby authorized to use moneys from its general fund to provide the costs specified in this subparagraph (I) and to deposit any moneys received as reimbursement pursuant to subsection (4) of this section into its general fund.

(B) Whenever construction occurs on any new taxable building within the boundaries of a county after January 1 of a given year, the assessor shall value the building on July 1 of that year, and the assessor shall add the valuation for assessment thereof to the abstract of assessment for such tax year, except that portion of the valuation for assessment as is excluded by paragraph (b) of this subsection (2). If the building is complete on July 1, such valuation for assessment shall be prorated at the same ratio as the number of months it is completed bears to the full year. Otherwise, the valuation added to the abstract shall be one-half of the difference between the valuation for assessment on January 1 and the valuation for assessment on July 1. For the purposes of this section, the total valuation for assessment of all newly constructed taxable buildings in a county as calculated pursuant to this subsection (2) shall be known as the "growth valuation for assessment" for such county. For purposes of this section, completion shall be considered to be when a certificate of occupancy is issued, when the building is ready for use, or after the final inspection, at the sole discretion of the county assessor. As used in this section, "building" means a roofed and walled real property improvement, and any uncertainty concerning whether or not a particular real property improvement is a building within the meaning of this definition shall be resolved by the property tax administrator.

(C) The assessor shall give written notification of the valuation of such newly constructed taxable building to the taxpayer. The notice shall, at a minimum, set forth the valuation on the assessment date, the prorated valuation of the newly constructed taxable building, and the total valuation for the property tax year. The notice shall also advise the taxpayer that he may protest and appeal the valuation of the newly constructed taxable building at the same time and in the same manner, pursuant to section 39-5-122, as the total valuation of his property for the next property tax year may be appealed. If the taxpayer is successful in the protest or appeal, the amount in excess shall be refunded directly to the taxpayer by the county treasurer.

(D) In order to promote the most efficient administration of this section, each county or municipality shall ensure that any office or agency that received information relative to the state of completion of new taxable buildings shall promptly transmit such information to the county assessor. After January 1, 1987, the property tax administrator shall transmit to the assessor in August of each year both the assessed value of any newly constructed buildings owned by public utility companies and their state of completion on July 1 as well as their value on the previous January 1.

(E) The growth criteria for school districts for purposes of sub-subparagraph (A) of this subparagraph (I) shall be whether the commissioner of education or the commissioner's designee certifies that the pupil enrollment of the district for the past three years, as determined on October 1 of each year in accordance with former section 22-53-103 (7) or section 22-54-103 (10), has increased by three percent or more over each preceding year for those districts with pupil enrollments of at least one thousand pupils or by twenty-five or more pupils each year for those districts with pupil enrollments of less than one thousand pupils.

(II) All general property taxes which are levied on all other taxable real and personal property within a county in the tax year during which such construction occurs shall also be levied against the growth valuation for assessment of such county for collection the following year. Revenues raised from taxes levied on such growth valuation for assessment shall be credited to the county's capital growth fund, which each board of county commissioners shall establish, for use and distribution pursuant to subsection (4) of this section. The actual value and valuation for assessment of such newly constructed taxable building for subsequent years shall be the actual value and valuation for assessment as determined by the provisions of law other than this section, and tax revenues attributable thereto shall be distributed as provided by law without regard to this section.

(b) The provisions of this section shall not apply to that portion of the valuation for assessment of a newly constructed taxable building and the land underlying such building which is contained in the abstract of assessment on the assessment date.

(c) If the newly constructed taxable building is a residential unit, the assessment percentage to be applied to the land underlying such building shall be based on a residential classification of the land. If the land underlying such building was classified as vacant land, the classification shall be changed to residential on the abstract of assessment for the tax year in which the assessor added the valuation of the newly taxable residential building to the abstract for assessment.

(3) By August 25 of each year, the assessor shall notify the board of county commissioners of the amount of the growth valuation for assessment of the county for that tax year, the percentage that such growth valuation for assessment bears to the total valuation for assessment of the county for such tax year, the portion of such growth valuation for assessment that is attributable to newly constructed taxable buildings within the boundaries of each taxing authority in the county, and the percentage that such portion bears to the total valuation for assessment of each taxing authority in which such newly constructed taxable buildings are located.

(4) Upon collection of taxes on the growth valuation for assessment in the first year, the board of county commissioners shall reimburse the county general fund and the taxing authorities which contributed to the costs of implementing the procedures specified pursuant to this section and shall also pay into the county general fund the projected budgeted costs of implementation in this second year. The remaining moneys shall be distributed to the taxing authorities as next specified in this subsection (4). In the second and subsequent years that procedures are implemented pursuant to this section, the board of county commissioners, after depositing into the county general fund the projected budgeted costs of administering this section in the current year, shall distribute the moneys in the county's capital growth fund to the taxing authorities where the newly constructed taxable building is actually located in the same manner as all other property tax revenues collected on similar taxable buildings are distributed; except that such moneys shall be used by the taxing authority for capital expenditures only and not for operating expenses.

39-5-133.  2011 modification of statutory definition of "agricultural land" - TABOR election - adjustment of district mill levy.

          (1) (a)  The requirements of paragraph (b) of this subsection (1) shall only apply:

          (I)  To a district, as defined in section 20 (2) (b) of article X of the state constitution, that has not obtained voter approval to retain and spend revenues in excess of the fiscal year spending and property tax revenue limits imposed on the district by section 20 (7) (b) and (c) of article X of the state constitution sufficient to allow the retention of all additional property tax revenues; and

          (II)  Where the district has additionally determined, on the basis of the best available information, that implementation of the modification of the definition of "agricultural land" required by House Bill 11-1146, enacted in 2011, will cause a net property tax revenue gain to the district sufficient to cause the district to exceed such limits. 

          (b)  In the case of a district that meets the requirements specified in paragraph (a) of this subsection (1), the district may place before the voters of the district at any election at which such ballot issue may be placed on the ballot the question of whether the district may retain and spend revenues in excess of the limits imposed on the district by section 20 (7) (b) and (c) of article X of the state constitution sufficient to allow the retention of the net property tax revenue gain to the district resulting from the implementation of the modification of the definition of "agricultural land" required by House Bill 11-1146, enacted in 2011.

              (c)  If a majority of the voters of the district fail to approve the ballot issue specified in paragraph (b) of this subsection (1), or if no ballot issue has been submitted to the voters, the district shall adjust the number of mills levied by the district to eliminate any net property tax revenue gain to the district resulting from the modification of the definition of "agricultural land" required by House Bill 11-1146, enacted in 2011.

              (2)  Notwithstanding any other provision of law, the provisions of subsection (1) of this section shall not apply to any district, regardless of whether or not it satisfies the requirements of paragraph (a) of subsection (1) of this section, that has determined, on the basis of the best available information, that implementation of the modification of the definition of "agricultural land" required by House Bill 11-1146, enacted in 2011, will not cause a net property tax revenue gain to the district.
