Property taxes in Oklahoma are assessed and collected at the local level — primarily by counties and municipalities — with rates varying significantly depending on where your home is located. The statewide average effective rate for 2025is 0.88%, meaning a homeowner with a $193,600 median-value home typically pays around $1,704 per year in property taxes. For a monthly perspective, that works out to roughly $142/month — a line item that should factor into every home purchase decision in Oklahoma.
Oklahoma uses a 11.0% assessment ratio for primary residential properties. This means the county assessor sets your home's taxable (assessed) value at 1100% of its market value. On a $400,000 home, for example, the taxable assessed value would be $44,000. Mill rates (the nominal tax rate per $1,000 of assessed value) are then applied to this lower figure.
Available Exemptions in Oklahoma
Homestead Exemption: $1,000 off assessed value (~$9,091 market value equivalent at 11% ratio). Seniors 65+ with income under $25,000: additional homestead exemption (double).
Senior Valuation Limitation: once qualified (65+, income under $75,000), assessed value of the property is frozen at current level — protecting against value increases.
100% service-connected disabled veterans: $200,000 off assessed value of their homestead. Oklahoma has one of the most generous veteran exemptions in the US.
What Makes Oklahoma's Property Tax System Unique
Oklahoma's 11% assessment ratio and $200,000 veteran exemption make it very tax-friendly for disabled veterans and owners of modest homes. Oklahoma County (Oklahoma City) and Tulsa County are the most populous. The Gross Production Tax on oil/gas reduces reliance on property taxes.
When Are Oklahoma Property Taxes Due?
Oklahoma property taxes are paid on a semi-annual (twice per year) basis. Due dates: December 31 and March 31. Missing a due date typically results in penalty interest (often 1–2% per month) and eventually tax liens, so it is important to calendar these dates well in advance — especially if you have a mortgage and your lender handles property tax through escrow (in which case they pay on your behalf from your escrow account).
How to Appeal Your Property Tax Assessment in Oklahoma
If you believe your property has been over-assessed — which is surprisingly common, especially after rapid market changes — you have the right to appeal. File with your county Board of Equalization from January 1–March 31. Be prepared to present evidence of market value.
To build a strong appeal, gather comparable sales (homes similar in size, age, and condition that sold recently for less than your assessed value), photos documenting property defects, and any independent appraisals you have. Many homeowners who appeal see their assessments reduced — and some jurisdictions allow free informal hearings before a formal appeal is required.

Pro Tips for Oklahoma Property Owners
- Apply for every exemption you qualify for — many homeowners leave money on the table by not filing for the homestead or senior exemption. Applications are typically annual or one-time, and deadlines are firm.
- Review your assessment notice every year. If the county's estimate of your home's market value seems too high relative to what similar homes are actually selling for, appeal it. Even a 10% reduction on a $400,000 assessment saves $400–$700/year at typical Oklahoma rates.
- If you have a mortgage, confirm with your lender whether property taxes are paid via an escrow account. If so, ensure your escrow balance is adequate — under-funded escrow leads to an escrow shortage and a sudden increase in your monthly mortgage payment.
- Pay early if your state offers discounts. Some states (like Florida) give 1–4% discounts for early payment. On a $5,000 tax bill, a 4% early-payment discount saves $200 — for essentially zero work.
- Property taxes are generally deductible on your federal income tax return as part of the SALT deduction (state and local taxes), subject to the $10,000 cap introduced by the Tax Cuts and Jobs Act. For high-tax states, this cap is often a binding constraint.
