Section 3

As amended November 6, 1956. (See Laws 1957, p. 796.); as amended November 2, 1982 ­­ Effective upon proclamation of the Governor, December 30, 1982. (See L. 82, p. 691.); as amended November 8, 1988 ­­ Effective upon proclamation of the Governor, January 1, 1989. (For the text of this amendment and the votes cast thereon, see L. 88, p. 1457, and L. 89, p. 1661.)

Text of Section 3: Uniform Taxation ­Exemptions (1) (a) Each property tax levy shall be uniform upon all real and personal property not exempt from taxation under this article located within the territorial limits of the authority levying the tax. The actual value of all real and personal property not exempt from taxation under this article shall be determined under general laws, which shall prescribe such methods and regulations as shall secure just and equalized valuations for assessments of all real and personal property not exempt from taxation under this article. Valuations for assessment shall be based on appraisals by assessing officers to determine the actual value of property in accordance with provisions of law, which laws shall provide that actual value be determined by appropriate consideration of cost approach, market approach, and income approach to appraisal. However, the actual value of residential real property shall be determined solely by consideration of cost approach and market approach to appraisal; and, however, the actual value of agricultural lands, as defined by law, shall be determined solely by consideration of the earning or productive capacity of such lands capitalized at a rate as prescribed by law. (b) Residential real property, which shall include all residential dwelling units and the land, as defined by law, on which such units are located, and mobile home parks, but shall not include hotels and motels, shall be valued for assessment at twenty­one percent of its actual value. For the property tax year commencing January 1, 1985, the general assembly shall determine the percentage of the aggregate statewide valuation for assessment which is attributable to residential real property. For each subsequent year, the general assembly shall again determine the percentage of the aggregate statewide valuation for assessment which is attributable to each class of taxable property, after adding in the increased valuation for assessment attributable to new construction and to increased volume of mineral and oil and gas production. For each year in which there is a change in the level of value used in determining actual value, the general assembly shall adjust the ratio of valuation for assessment for residential real property which is set forth in this paragraph (b) as is necessary to insure that the percentage of the aggregate statewide valuation for assessment which is attributable to residential real property shall remain the same as it was in the year immediately preceding the year in which such change occurs. Such adjusted ratio shall be the ratio of valuation for assessment for residential real property for those years for which such new level of value is used. All other taxable property shall be valued for assessment at twenty­nine percent of its actual value. However, the valuation for assessment for producing mines, as defined by law, and lands or leaseholds producing oil or gas, as defined by law, shall be a portion of the actual annual or actual average annual production therefrom, based upon the value of the unprocessed material, according to procedures prescribed by law for different types of minerals. Non­producing unpatented mining claims, which are possessory interests in real property by virtue of leases from the United States of America, shall be exempt from property taxation. (c) The following classes of personal property, as defined by law, shall be exempt from property taxation: Household furnishings and personal effects which are not used for the production of income at any time; inventories of merchandise and materials and supplies which are held for consumption by a business or are held primarily for sale; livestock; agricultural and livestock products; and agricultural equipment which is used on the farm or ranch in the production of agricultural products. (d) Ditches, canals, and flumes owned and used by individuals or corporations for irrigating land owned by such individuals or corporations, or the individual members thereof, shall not be separately taxed so long as they shall be owned and used exclusively for such purposes. (2) (a) During each property tax year beginning with the property tax year which commences January 1, 1983, the general assembly shall cause a valuation for assessment study to be conducted. Such study shall determine whether or not the assessor of each county has complied with the property tax provisions of this constitution and of the statutes in valuing property and has determined the actual value and valuation for assessment of each and every class of taxable real and personal property consistent with such provisions. Such study shall sample at least one percent of each and every class of taxable real and personal property in the county. (b) (I) If the study conducted during the property tax year which commences January 1, 1983, shows that a county assessor did not comply with the property tax provisions of this constitution or the statutes or did not determine the actual value or the valuation for assessment of any class or classes of taxable real and personal property consistent with such provisions, the state board of equalization shall, during such year, order such county assessor to reappraise during the property tax year which commences January 1, 1984, such class or classes for such year. Such reappraisal shall be performed at the expense of the county. (II) If the study performed during the property tax year which commences January 1, 1984, shows that the county assessor failed to reappraise such class or classes as ordered or failed in his reappraisal to meet the objections of the state board of equalization, the state board of equalization shall cause a reappraisal of such class or classes to be performed in the property tax year which commences January 1, 1985. The cost of such reappraisal shall be paid by the state by an appropriation authorized by law. However, if such reappraisal shows that the county assessor did not value or assess taxable property as prescribed by the provisions of this constitution or of the statutes, upon certification to the board of county commissioners by the state board of equalization of the cost thereof, the board of county commissioners shall pay to the state the cost of such reappraisal. (III) The reappraisal performed in the property tax year which commences January 1, 1985, shall become the county's abstract for assessment with regard to such reappraised class or classes for such year. The state board of equalization shall order the county's board of county commissioners to levy, and the board of county commissioners shall levy, in 1985 an additional property tax on all taxable property in the county in an amount sufficient to repay, and the board of county commissioners shall repay, the state for any excess payment made by the state to school districts within the county during the property tax year which commences January 1, 1985. (c) (I) Beginning with the property tax year which commences January 1, 1985, and applicable to each property tax year thereafter, the annual study conducted pursuant to paragraph (a) of this subsection (2) shall, in addition to the requirements set forth in paragraph (a) of this subsection (2), set forth the aggregate valuation for assessment of each county for the year in which the study is conducted. (II) If the valuation for assessment of a county as reflected in its abstract for assessment is more than five percent below the valuation for assessment for such county as determined by the study, during the next following year, the state board of equalization shall cause to be performed, at the expense of the county, a reappraisal of any class or classes of taxable property which the study shows were not appraised consistent with the property tax provisions of this constitution or the statutes. The state board of equalization shall cause to be performed during the next following year, at the expense of the county, a reappraisal of any class or classes of taxable property which the study shows were not appraised consistent with the property tax provisions of this constitution or the statutes even though the county's aggregate valuation for assessment as reflected in the county's abstract for assessment was not more than five percent below the county's aggregate valuation for assessment as determined by the study. The reappraisal shall become the county's valuation for assessment with regard to such reappraised class or classes for the year in which the reappraisal was performed. (III) In any case in which a reappraisal is ordered, state equalization payments to school districts within the county during the year in which the reappraisal is performed shall be based upon the valuation for assessment as reflected in the county's abstract for assessment. The state board of equalization shall also order the board of county commissioners of the county to impose, and the board of county commissioners shall impose, at the time of imposition of property taxes during such year an additional property tax on all taxable property within the county in an amount sufficient to repay, and the board of county commissioners shall repay, the state for any excess payments made by the state to school districts within the county during the year in which such reappraisal was performed plus interest thereon at a rate and for such time as are prescribed by law. (IV) If the valuation for assessment of a county as reflected in its abstract for assessment is more than five percent below the valuation for assessment for such county as determined by the study and if the state board of equalization fails to order a reappraisal, state equalization payments to school districts within the county during the year following the year in which the study was conducted shall be based upon the valuation for assessment for the county as reflected in the county's abstract for assessment. The board of county commissioners of such county shall impose in the year in which such school payments are made an additional property tax on all taxable property in the county in an amount sufficient to repay, and the board of county commissioners shall repay, the state for the difference between the amount the state actually paid in state equalization payments during such year and what the state would have paid during such year had such state payments been based on the valuation for assessment as determined by the study.

Section 3.5

Text of Section 3.5: Homestead exemption for qualifying senior citizens and disabled veterans (1) For property tax years commencing on or after January 1, 2002, fifty percent of the first two hundred thousand dollars of actual value of residential real property, as defined by law, that, as of the assessment date, is owner-occupied and is used as the primary residence of the owner-occupier shall be exempt from property taxation if: (a) The owner-occupier is sixty-five years of age or older as of the assessment date and has owned and occupied such residential real property as his or her primary residence for the ten years immediately preceding the assessment date; (b) The owner-occupier is the spouse or surviving spouse of an owner-occupier who previously qualified for a property tax exemption for the same residential real property under paragraph (a) of this subsection (1); or (c) For property tax years commencing on or after January 1, 2007, only, the owner-occupier, as of the assessment date, is a disabled veteran. (1.3) An owner-occupier may claim only one exemption per property tax year even if the owner-occupier qualifies for an exemption under both paragraph (c) of subsection (1) of this section and either paragraph (a) or paragraph (b) of subsection (1) of this section. (1.5) For purposes of this section, "disabled veteran" means an individual who has served on active duty in the United States armed forces, including a member of the Colorado national guard who has been ordered into the active military service of the United States, has been separated therefrom under honorable conditions, and has established a service-connected disability that has been rated by the federal department of veterans affairs as one hundred percent permanent disability through disability retirement benefits or a pension pursuant to a law or regulation administered by the department, the department of homeland security, or the department of the army, navy, or air force. (2) Notwithstanding the provisions of subsection (1) of this section, section 20 of this article, or any other constitutional provision, for any property tax year commencing on or after January 1, 2003, the general assembly may raise or lower by law the maximum amount of actual value of residential real property of which fifty percent shall be exempt under subsection (1) of this section. (3) For any property tax year commencing on or after January 1, 2002, the general assembly shall compensate each local governmental entity that receives property tax revenues for the net amount of property tax revenues lost as a result of the property tax exemption provided for in this section. For purposes of section 20 of article X of this constitution, such compensation shall not be included in local government fiscal year spending and approval of this section by the voters statewide shall constitute a voter-approved revenue change to allow the maximum amount of state fiscal year spending for the 2001-02 state fiscal year to be increased by forty-four million one hundred twenty-three thousand six hundred four dollars and to include said amount in state fiscal year spending for said state fiscal year for the purpose of calculating subsequent state fiscal year spending limits. Payments made from the state general fund to compensate local governmental entities for property tax revenues lost as a result of the property tax exemption provided for in this section shall not be subject to any statutory limitation on general fund appropriations because the enactment of this section by the people of Colorado constitutes voter approval of a weakening of any such limitation.

Section 20

Text of Section 20: The Taxpayer's Bill of Rights (1) General provisions. This section takes effect December 31, 1992 or as stated. Its preferred interpretation shall reasonably restrain most the growth of government. All provisions are self-executing and severable and supersede conflicting state constitutional, state statutory, charter, or other state or local provisions. Other limits on district revenue, spending, and debt may be weakened only by future voter approval. Individual or class action enforcement suits may be filed and shall have the highest civil priority of resolution. Successful plaintiffs are allowed costs and reasonable attorney fees, but a district is not unless a suit against it be ruled frivolous. Revenue collected, kept, or spent illegally since four full fiscal years before a suit is filed shall be refunded with 10% annual simple interest from the initial conduct. Subject to judicial review, districts may use any reasonable method for refunds under this section, including temporary tax credits or rate reductions. Refunds need not be proportional when prior payments are impractical to identify or return. When annual district revenue is less than annual payments on general obligation bonds, pensions, and final court judgments, (4) (a) and (7) shall be suspended to provide for the deficiency. (2) Term definitions. Within this section: (a) "Ballot issue" means a non-recall petition or referred measure in an election. (b) "District" means the state or any local government, excluding enterprises. (c) "Emergency" excludes economic conditions, revenue shortfalls, or district salary or fringe benefit increases. (d) "Enterprise" means a government-owned business authorized to issue its own revenue bonds and receiving under 10% of annual revenue in grants from all Colorado state and local governments combined. (e) "Fiscal year spending" means all district expenditures and reserve increases except, as to both, those for refunds made in the current or next fiscal year or those from gifts, federal funds, collections for another government, pension contributions by employees and pension fund earnings, reserve transfers or expenditures, damage awards, or property sales. (f) "Inflation" means the percentage change in the United States Bureau of Labor Statistics Consumer Price Index for Denver-Boulder, all items, all urban consumers, or its successor index. (g) "Local growth" for a non-school district means a net percentage change in actual value of all real property in a district from construction of taxable real property improvements, minus destruction of similar improvements, and additions to, minus deletions from, taxable real property. For a school district, it means the percentage change in its student enrollment. (3) Election provisions. (a) Ballot issues shall be decided in a state general election, biennial local district election, or on the first Tuesday in November of odd-numbered years. Except for petitions, bonded debt, or charter or constitutional provisions, districts may consolidate ballot issues and voters may approve a delay of up to four years in voting on ballot issues. District actions taken during such a delay shall not extend beyond that period. (b) At least 30 days before a ballot issue election, districts shall mail at the least cost, and as a package where districts with ballot issues overlap, a titled notice or set of notices addressed to "All Registered Voters" at each address of one or more active registered electors. The districts may coordinate the mailing required by this paragraph (b) with the distribution of the ballot information booklet required by section 1 (7.5) of article V of this constitution in order to save mailing costs. Titles shall have this order of preference: "NOTICE OF ELECTION TO INCREASE TAXES/TO INCREASE DEBT/ON A CITIZEN PETITION/ON A REFERRED MEASURE." Except for district voter-approved additions, notices shall include only: (i) The election date, hours, ballot title, text, and local election office address and telephone number. (ii) For proposed district tax or bonded debt increases, the estimated or actual total of district fiscal year spending for the current year and each of the past four years, and the overall percentage and dollar change. (iii) For the first full fiscal year of each proposed district tax increase, district estimates of the maximum dollar amount of each increase and of district fiscal year spending without the increase. (iv) For proposed district bonded debt, its principal amount and maximum annual and total district repayment cost, and the principal balance of total current district bonded debt and its maximum annual and remaining total district repayment cost. (v) Two summaries, up to 500 words each, one for and one against the proposal, of written comments filed with the election officer by 45 days before the election. No summary shall mention names of persons or private groups, nor any endorsements of or resolutions against the proposal. Petition representatives following these rules shall write this summary for their petition. The election officer shall maintain and accurately summarize all other relevant written comments. The provisions of this subparagraph (v) do not apply to a statewide ballot issue, which is subject to the provisions of section 1 (7.5) of article V of this constitution. (c) Except by later voter approval, if a tax increase or fiscal year spending exceeds any estimate in (b) (iii) for the same fiscal year, the tax increase is thereafter reduced up to 100% in proportion to the combined dollar excess, and the combined excess revenue refunded in the next fiscal year. District bonded debt shall not issue on terms that could exceed its share of its maximum repayment costs in (b) (iv). Ballot titles for tax or bonded debt increases shall begin, "SHALL (DISTRICT) TAXES BE INCREASED (first, or if phased in, final, full fiscal year dollar increase) ANNUALLY...?" or "SHALL (DISTRICT) DEBT BE INCREASED (principal amount), WITH A REPAYMENT COST OF (maximum total district cost), ...?" (4) Required elections. Starting November 4, 1992, districts must have voter approval in advance for: (a) Unless (1) or (6) applies, any new tax, tax rate increase, mill levy above that for the prior year, valuation for assessment ratio increase for a property class, or extension of an expiring tax, or a tax policy change directly causing a net tax revenue gain to any district. (b) Except for refinancing district bonded debt at a lower interest rate or adding new employees to existing district pension plans, creation of any multiple-fiscal year direct or indirect district debt or other financial obligation whatsoever without adequate present cash reserves pledged irrevocably and held for payments in all future fiscal years. (5) Emergency reserves. To use for declared emergencies only, each district shall reserve for 1993 1% or more, for 1994 2% or more, and for all later years 3% or more of its fiscal year spending excluding bonded debt service. Unused reserves apply to the next year's reserve. (6) Emergency taxes. This subsection grants no new taxing power. Emergency property taxes are prohibited. Emergency tax revenue is excluded for purposes of (3) (c) and (7), even if later ratified by voters. Emergency taxes shall also meet all of the following conditions: (a) A 2/3 majority of the members of each house of the general assembly or of a local district board declares the emergency and imposes the tax by separate recorded roll call votes. (b) Emergency tax revenue shall be spent only after emergency reserves are depleted, and shall be refunded within 180 days after the emergency ends if not spent on the emergency. (c) A tax not approved on the next election date 60 days or more after the declaration shall end with that election month. (7) Spending limits. (a) The maximum annual percentage change in state fiscal year spending equals inflation plus the percentage change in state population in the prior calendar year, adjusted for revenue changes approved by voters after 1991. Population shall be determined by annual federal census estimates and such number shall be adjusted every decade to match the federal census. (b) The maximum annual percentage change in each local district's fiscal year spending equals inflation in the prior calendar year plus annual local growth, adjusted for revenue changes approved by voters after 1991 and (8) (b) and (9) reductions. (c) The maximum annual percentage change in each district's property tax revenue equals inflation in the prior calendar year plus annual local growth, adjusted for property tax revenue changes approved by voters after 1991 and (8) (b) and (9) reductions. (d) If revenue from sources not excluded from fiscal year spending exceeds these limits in dollars for that fiscal year, the excess shall be refunded in the next fiscal year unless voters approve a revenue change as an offset. Initial district bases are current fiscal year spending and 1991 property tax collected in 1992. Qualification or disqualification as an enterprise shall change district bases and future year limits. Future creation of district bonded debt shall increase, and retiring or refinancing district bonded debt shall lower, fiscal year spending and property tax revenue by the annual debt service so funded. Debt service changes, reductions, (1) and (3) (c) refunds, and voter-approved revenue changes are dollar amounts that are exceptions to, and not part of, any district base. Voter-approved revenue changes do not require a tax rate change. (8) Revenue limits. (a) New or increased transfer tax rates on real property are prohibited. No new state real property tax or local district income tax shall be imposed. Neither an income tax rate increase nor a new state definition of taxable income shall apply before the next tax year. Any income tax law change after July 1, 1992 shall also require all taxable net income to be taxed at one rate, excluding refund tax credits or voter-approved tax credits, with no added tax or surcharge. (b) Each district may enact cumulative uniform exemptions and credits to reduce or end business personal property taxes. (c) Regardless of reassessment frequency, valuation notices shall be mailed annually and may be appealed annually, with no presumption in favor of any pending valuation. Past or future sales by a lender or government shall also be considered as comparable market sales and their sales prices kept as public records. Actual value shall be stated on all property tax bills and valuation notices and, for residential real property, determined solely by the market approach to appraisal. (9) State mandates. Except for public education through grade 12 or as required of a local district by federal law, a local district may reduce or end its subsidy to any program delegated to it by the general assembly for administration. For current programs, the state may require 90 days notice and that the adjustment occur in a maximum of three equal annual installments.
