About Property Taxes in Oklahoma
Oklahoma property taxes are administered at the county level. Residential property is assessed at 11% of fair cash value, agricultural at 11%, and commercial at 11% as well (though rates vary by use). Oklahoma's assessment ratios and mill rates produce among the lower effective property tax rates in the country. Oklahoma also has a distinctive feature: the assessed value of owner-occupied primary residences cannot increase by more than 3% per year (the "assessment limitation"), regardless of market value increases. This provides strong protection against rapid tax increases for homeowners.
Payment & Assessment
Oklahoma property taxes are due December 31 and may be paid in two equal installments: First half: Due December 31 Second half: Due March 31 of the following year If the total tax is less than $100, it must be paid in full by December 31. A penalty of 1.5% per month applies to late payments. Most counties offer online payment. Contact your county treasurer for payment options.
