ZIP doesn't have ACS data — typically because it's a PO-box-only ZIP, a single-business ZIP, or a small area where the Census suppresses small-sample estimates. Try a nearby ZIP.

Oklahoma's effective property-tax rate runs low — around 0.80% of value statewide — for two structural reasons. The state constitution lets a county tax only between 11% and 13.5% of a property's fair cash value, and an annual cap limits how fast a homestead's taxable value can grow. The county assessor sets the value; the county treasurer sends the bill.

The explainer below covers the assessment ratio, the valuation cap, the homestead exemptions and senior freeze, and a proposed ballot measure that would phase the tax out for homeowners.
How Oklahoma property tax works
Oklahoma assesses property locally, and only a slice of value is ever taxed. The state constitution (Article 10) requires each county's assessment percentage to fall between 11% and 13.5% of fair cash value, so a home worth $200,000 might carry an assessed value near $22,000–$27,000 before the local millage applies. The same article caps the annual increase in a property's taxable fair cash value at 3% for a homestead or agricultural land (and 5% for other real property), with the cap resetting when the property is sold or improved — which keeps long-held homes from being repriced to market all at once.
The standard homestead exemption removes $1,000 of assessed value from an owner-occupied home, and an additional homestead exemption removes a further $1,000 of assessed value for households whose gross income was $30,000 or less in the prior year. For older homeowners, the Senior Valuation Limitation freezes the property's fair cash value (not the tax itself, so millage can still change) once the owner is 65 or older and the household income is at or below the county's HUD median-income figure, which is set annually and varies by county. Veterans with a 100% permanent service-connected disability — and qualifying surviving spouses — can claim a full exemption of the homestead's fair cash value.
Oklahoma is also part of the national property-tax debate. A proposed ballot measure, State Question 843, would phase out property tax on owner-occupied homesteads — exempting one third of assessed value in 2027, two thirds in 2028, and the full value from 2029 on. Important framing: this is a citizen initiative petition, not law. It was filed in early 2026 and is under review by the Oklahoma Supreme Court, with signature-gathering paused pending the court's decision on whether it can proceed.
Why your actual bill differs
The numbers above describe a typical homeowner in this ZIP — not your specific bill. A few things move bills away from the median:
- The county assessment ratio and millage both vary. Two homes of equal fair cash value in different counties can differ because one county assesses at 11% and another nearer 13.5%, and because each layers on its own school and local mills.
- How long you've owned it. The 3% annual cap on a homestead's taxable value means a long-held home can sit well below market, while a recent purchase resets to current value — so neighbors with identical homes can owe quite different amounts.
- Exemptions and the senior freeze. The homestead exemptions, the senior valuation freeze, and the full disabled-veteran exemption each pull a qualifying owner's bill below the ZIP median.
Oklahoma has no single statewide bill lookup — each county treasurer runs its own. The Oklahoma County Treasurer's public-access search is a working example; for other counties, start with your county treasurer's office.
Methodology
Data on this page comes from the US Census American Community Survey 5-year estimates, 2020–2024 vintage (released January 29, 2026), at the ZIP Code Tabulation Area (ZCTA) level. After filtering ZCTAs the Census suppresses for privacy or small-sample reasons, this page covers 602 Oklahoma ZIPs.
Topcoding in Oklahoma. The Census caps median property tax at $10,000, reporting anything higher as $10,001. Oklahoma's low assessment ratio and moderate values keep every ZIP in this dataset below the cap, so the figures here are true medians.

Frequently asked questions
Why is the median tax in my ZIP different from what I pay?
Median is the middle of the distribution, not your bill. Oklahoma taxes only 11%–13.5% of fair cash value, the county sets that ratio and the millage, and a 3% annual cap limits how fast a homestead's taxable value rises. The homestead exemptions and senior freeze move qualifying owners further from the median.
Why might my ZIP show $10,001 as the median tax?
That's the Census topcode for privacy, but it doesn't appear in Oklahoma — the low assessment ratio and moderate values keep every ZIP in this dataset below the $10,000 cap, so the figures here are true medians.
Where do I find my actual Oklahoma property tax bill?
Through your county treasurer. Oklahoma has no statewide pay-your-bill portal; each county runs its own. The Oklahoma County Treasurer's search is a working example.
When does Oklahoma data update on this page?
Annually, when the Census Bureau releases a new ACS 5-year vintage. The 2020–2024 vintage released January 29, 2026. The next vintage (2021–2025) typically follows the next year, though the Census has not yet posted its release date.
Why don't you cover other states yet?
State-by-state rollout. Each state needs its own context section (assessment method, exemptions, local taxing structure) to be genuinely useful. High-search-volume states are going live first.
