How Property Tax Works

Washita County, Oklahoma operates under the state's property tax system to fund essential local services including schools, county government operations, emergency services, and infrastructure maintenance. Property taxes in Oklahoma are administered at the county level, with the Washita County Assessor determining property values and the County Treasurer collecting payments. The county follows Oklahoma's assessment practices where real property is typically assessed at 11-13.5% of fair cash value for residential properties.

Property tax rates in Washita County vary significantly by location within the county due to different combinations of special taxing districts, including school districts, municipal bonds, and local improvement districts. Based on available data for 2025, the effective tax rate is approximately 0.02%, though this represents only a portion of the total tax burden as it may not include all special district assessments. Actual rates paid by property owners typically range higher when all applicable district taxes are combined. The county reassesses properties annually, with tax bills reflecting values as of January 1st of each tax year.

When Are Property Taxes Due?

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Washita County are additional tax assessments that occur when there are changes to property ownership, value, or use during the tax year. The most common triggers include the sale of property to a new owner, completion of new construction or major improvements, and changes in property use classification. These taxes are calculated based on the difference between the old and new assessed values, prorated for the portion of the tax year remaining after the change occurs.

For example, if a property owner completes a $100,000 home addition in July, the supplemental tax would be calculated on the increased assessed value (typically 11-13.5% of the improvement value) for the remaining months of the tax year. The supplemental bill would be issued separately from the annual property tax bill and would have its own due date, typically within 30 days of issuance.

Escrow & Property Taxes

Most mortgage lenders in Washita County require borrowers to maintain an escrow account for property tax payments, especially for loans with less than 20% down payment. The lender collects monthly escrow payments equal to 1/12th of the annual property tax bill, plus additional amounts for property insurance. Since Washita County property taxes can be paid in two installments (first half due by May 1, second half due by November 1), lenders typically make payments on behalf of homeowners according to this schedule.

Property owners should verify their escrow payments annually when tax bills are issued, as changes in assessed value or tax rates can affect the required monthly escrow amount. Lenders are required to provide annual escrow analysis statements showing projected taxes and any shortage or surplus. If taxes increase significantly due to reassessment or new special district taxes, lenders may require additional escrow payments or increase monthly payments to avoid shortages. Homeowners can request copies of their property tax bills from their lender and should review them to ensure accurate payment of all applicable taxes and proper application of any tax credits they've applied for.
