Okla. Stat. tit. 68, § 2831 (2026)

A. All property, both real and personal, having an actual, constructive or taxable situs in this state, shall, except as hereinafter provided, be listed and assessed and taxable in the county, school districts, and municipal subdivision thereof, where actually located on the first day of January of each year. In all cases oil field equipment, drilling equipment, construction equipment, road machinery, and equipment used by construction, road building, or drilling contractors or companies or individuals engaged in such businesses, shall be taxable in the county, school districts, and municipal subdivision thereof, where actually located on the first day of January of each year, but if same is not assessed in said county it shall be subject to assessment and taxation in the county of the owner's domicile. Goods, wares, merchandise and property becoming a part of the finished product of drilling equipment, for use outside the continental United States shall not be subject to any other taxes. B. When any personal property is brought into or located in this state or removed from one county to another within this state between January 1 and September 1, and shall acquire an actual situs therein before the first of September, such property shall be listed and assessed and taxable where situated after such removal or change in location, unless such property has already been assessed in some other state or county for the current year, or the property was originally produced in this state subsequent to January 1, but if same is not assessed in said county it shall be subject to assessment and taxation in the county of the owner's domicile. C. When cattle or other livestock are pastured or kept on a tract of land situated partially within each of two or more counties or other taxing districts, so that they may roam or be driven from one county or taxing district to another and are not kept in any one county or taxing district, the number to be listed and assessed in each county or taxing district shall be determined by ascertaining the acreage proportion of the entire tract which is located in each county or taxing district and applying the same proportion to the total number of cattle or other livestock. When cattle or other livestock are likewise pastured or kept on a tract of land situated partially in the State of Oklahoma and partially in some other state, the number having a taxable situs in Oklahoma shall be determined in like manner.

D. In any case where other personal property, by reason of its nature or use, does not stay in one place long enough to acquire a definite taxable situs, such property shall be listed and assessed at the domicile of the owner, if the owner is domiciled in this state, and otherwise in the county, school districts, and municipal subdivision thereof, where the owner has his principal business in this state. E. Tangible personal property moving through the state from a point outside the state, in transit to a final destination outside the state, shall for purposes of taxation, acquire no situs in the state. The owner shall, if required, in order to obtain a determination that any property has not acquired a situs in the state, submit to the appropriate assessing officer documentary proof of the in-transit character and the final destination of the property.
