Okla. Const. art. X, § 8 – Valuation of property for taxation

A. Except as otherwise provided in Article X of this Constitution, beginning January 1, 1997, all property which may be taxed ad valorem shall be assessed for taxation as follows:
1. 1. Tangible personal property shall not be assessed for taxation at less than ten percent (10%) nor more than fifteen percent (15%) of its fair cash value, estimated at the price it would bring at a fair voluntary sale;
2. 2. Real property shall not be assessed for ad valorem taxation at a value less than eleven percent (11%) nor greater than thirteen and one-half percent (13.5%) of its fair cash value for the highest and best use for which such property was actually used, or was previously classified for use, during the calendar year next preceding the first day of January on which the assessment is made. The transfer of property without a change in its use classification shall not require a reassessment based exclusively upon the sale value of such property. In connection with the foregoing, the Legislature shall be empowered to enact laws defining classifications of use for the purpose of applying standards to facilitate uniform assessment procedures in this state; and
3. 3. All other property which is assessed by the State Board of Equalization shall be assessed for ad valorem taxation at the percentage of its fair cash value, estimated at the price it would bring at a fair voluntary sale, at which it was assessed on January 1, 1996.
B. Beginning January 1, 1997, the percentage at which real or tangible personal property is assessed within a county shall not be increased except upon approval by a majority of the registered voters of the county, voting at an election called for that purpose by a majority of the county commissioners, or upon a petition initiated by not less than ten percent (10%) of the registered voters of the county based on the total number of votes cast at the last general election for the county office receiving the highest number of votes at the election. In no event shall the percentage be increased by more than one percentage point per year or increase in excess of the limitations set forth in paragraphs 1 and 2 of subsection A of this section. The percentage at which real or tangible personal property is assessed within a county may be decreased, within the limitations set forth in paragraphs 1 and 2 of subsection A of this section, without approval of the voters of the county.
C. Any officer or other person authorized to assess values or subjects for taxation, who shall commit any wilful error in the performance of the duties of the office, shall be deemed guilty of malfeasance, and upon conviction thereof shall forfeit the office and be otherwise punished as may be provided by law.
