The Ad Valorem Division of the Oklahoma Tax Commission shall be
responsible for the promulgation of rules which shall be followed by
each county assessor of the state, for the purposes of providing for
the equitable use valuation of locally assessed real property in
this state. Agricultural land and nonresidential improvements
necessary or convenient for agricultural purposes shall be assessed
for ad valorem taxation based upon the highest and best use for
which the property was actually used, or was previously classified
for use, during the calendar year next preceding January 1 on which
the assessment is made.
C. The use value of agricultural land shall be based on the
income capitalization approach using cash rent. The rental income
shall be calculated using the direct capitalization method based
upon factors including, but not limited to:
1. Soil types, as depicted on soil maps published by the
Natural Resources Conservation Service of the United States
Department of Agriculture;
2. Soil productivity indices approved by the Ad Valorem
Division of the Tax Commission;

categories approved by the Ad Valorem Division of the Tax
Commission; and

average first mortgage interest rate charged by the Federal Land
Bank for the immediately preceding five (5) years, weighted with the
prevailing rate or rates for additional loans or equity, and the
effective tax rate.
The final use value will be calculated using the soil
productivity indices and the agricultural use classification as
defined by rules promulgated by the State Board of Equalization.
This subsection shall not be construed in a manner which is
inconsistent with the duties, powers, and authority of the Board as
to valuation of the counties as fixed and defined by Section 21 of
Article X of the Oklahoma Constitution.
However, in calculating the use value of buffer strips as
defined in Section 2817.2 of this title, exclusive consideration
shall be based only on income from production agriculture from such
buffer strips, not including federal or state subsidies, when valued
as required by subsection C of Section 2817.2 of this title.
D. The use value of nonresidential improvements on agricultural
land shall be based on the cost approach to value estimation using
currently updated cost manuals published by the Marshall and Swift
Company or similar cost manuals approved by the Ad Valorem Division
of the Tax Commission. The use value estimates for the
nonresidential improvements shall take obsolescence and depreciation
into consideration in addition to necessary adjustments for local
variations in the cost of labor and materials. This section shall

not be construed in a manner which is inconsistent with the duties,

of the counties as determined and defined by Section 21 of Article X
of the Oklahoma Constitution.
The use value of facilities used for poultry production shall be
determined according to the following procedures:
1. The Ad Valorem Division of the Tax Commission is hereby
directed to develop a standard system of valuation of both real and
personal property of such facilities, which shall be used by all
county assessors in this state, under which valuation based on the
following shall be presumed to be the fair cash value of the
property:
a. for real property, a ten-year depreciation schedule,
at the end of which the residual value is twenty
percent (20%) of the value of the facility during its
first year of operation, and
b. for personal property, a five-year depreciation
schedule, at the end of which the residual value is
zero;
2. Such facilities shall be valued only in comparison to other
facilities used exclusively for poultry production. Such a facility
which is no longer used for poultry production shall be deemed to
have no productive use;

3. During the first year such a facility is placed on the tax
rolls, its fair cash value shall be presumed to be the lesser of the
actual purchase price or the actual documented cost of construction;
and
4. For the purpose of determining the valuation of
nonresidential improvements used for poultry production, the
provisions of this subsection shall be applicable and such
improvements shall not be considered to be commercial property.
E. The value of investment in property used exclusively by an
oil refinery that is used wholly as a facility, device, or method
for the desulphurization of gasoline or diesel fuel as defined in
Section 2817.3 of this title shall not be included in the
capitalization used in the determination of fair market value of
such oil refinery if such property would qualify as exempt property
pursuant to Section 2902 of this title, whether or not an
application for such exemption is made by an otherwise qualifying
manufacturing concern owning the property described by Section
2817.3 of this title.
F. The use value of a lot in any platted addition or a
subdivision in a city, town, or county zoned for residential,
commercial, industrial, or other use shall be deemed to be the fair
cash value of the underlying tract of land platted, divided by the
number of lots contained in the platted addition or subdivision
until the lot shall have been conveyed to a bona fide purchaser or

the lot with building or buildings located thereon shall have been
occupied other than as a sales office by the owner thereof, or shall
have been leased, whichever event shall first occur. One who
purchases a lot for the purposes of constructing and selling a
building on such lot shall not be deemed to be a bona fide purchaser
for purposes of this section. However, if the lot is held for a
period longer than two (2) years before construction, then the
assessor may consider the lot to have been conveyed to a bona fide
purchaser. The cost of any land or improvements to any real
property required to be dedicated to public use including, but not
limited to, streets, curbs, gutters, sidewalks, storm or sanitary
sewers, utilities, detention or retention ponds, easements, parks,
or reserves shall not be utilized by the county assessor in the
valuation of any real property for assessment purposes.
G. The transfer of real property without a change in its use
classification shall not require a reassessment thereof based
exclusively upon the sale value of the property. However, if the
county assessor determines:
1. That by reason of the transfer of a property there is a
change in the actual use or classification of the property; or
2. That by reason of the amount of the sales consideration it
is obvious that the use classification prior to the transfer of the
property is not commensurate with and would not justify the amount
of the sales consideration of the property;

then the assessor shall, in either event, reassess the property for
the new use classification for which the property is being used, or,
the highest and best use classification for which the property may,
by reason of the transfer, be classified for use.
H. When the term “fair cash value” or the language “fair cash
value, estimated at the price it would bring at a fair voluntary
sale” is used in the Ad Valorem Tax Code, in connection with and in
relation to the assessment of real property, it is defined to mean
and shall be given the meaning ascribed and assigned to it in this
section and when the term or language is used in the Code in
connection with the assessment of personal property, it shall be
given its ordinary or literal meaning.
I. Where any real property is zoned for a use by a proper
zoning authority, and the use of the property has not been changed,
the use and not zoning shall determine assessment. Any reassessment
required shall be effective January 1 following the change in use.
Taxable real property need not be listed annually with the county
assessor.
J. If any real property shall become taxable after January 1 of
any year, the county assessor shall assess the same and place it
upon the tax rolls for the next ensuing year. When any building is
constructed upon land after January 1 of any year, the value of the
building shall be added by the county assessor to the assessed
valuation of the land upon which the building is constructed at the

fair cash value thereof for the next ensuing year. However, after
the building has been completed it shall be deemed to have a value
for assessment purposes of the fair cash value of the materials used
in such building only, until the building and the land on which the
building is located shall have been conveyed to a bona fide
purchaser or shall have been occupied or used for any purpose other
than as a sales office by the owner thereof, or shall have been
leased, whichever event shall first occur. The county assessor
shall continue to assess the building based upon the fair market
value of the materials used therein until the building and land upon
which the building is located shall have been conveyed to a bona
fide purchaser or is occupied or used for any purpose other than as
a sales office by the owner thereof, or is leased, whichever event
shall first occur. In the event a building or buildings described
by this subsection are intended to serve primarily as residential
rental housing, after the building or buildings have been completed
they shall be deemed to have an initial value for assessment
purposes not to exceed the fair cash value of the land and the
actual documented cost of any improvements made to the building or
buildings. The county assessor shall continue to assess such
building or buildings at a value not to exceed the fair cash value
of the land and actual documented cost of any improvements made
until either one (1) year has passed since the date on which the
building or buildings were first reflected on the tax rolls, or the

building or buildings and the land on which the building or
buildings are located shall have been conveyed to a bona fide

K. In the event improvements on land or personal property
located therein or thereon are destroyed or partially destroyed, or
the land itself is impaired or partially impaired by fire,
lightning, storm, winds, floodwaters, overflow of streams, or other
cause (all such destruction or impairments being referred to herein
as “damage”) during any year, the county assessor shall determine
the amount of damage and shall reassess the property for that year
at the fair cash value of the property, taking into account the
actual loss of functional use of the property occasioned by such
damage. The assessor shall make the appropriate value adjustments
to the property for that tax year up to the time at which the
assessor publishes the “Assessor’s assessor’s Report to the Excise
Board” Board as required by subsection D of Section 2867 of this
title. After such time, adjustments can be made only by the county
board of tax roll corrections and only after the assessor has
certified the tax roll for that year. The board secretary shall
notify property owners in advance of the time and place at which the
value adjustment to their property will be heard by the board. The
board of tax roll corrections is authorized only to approve or
reject the value adjustment submitted by the county assessor.
