Oklahoma tax guide: sales, income and property tax
Three taxes decide most everyday money calculations in Oklahoma: what you pay at the register, what leaves your paycheck, and what your home costs each year. This guide sets out each one with the current figures, then links to the calculators that apply them. Rates are reviewed against state sources; confirm a specific transaction with the Oklahoma Department of Revenue.
The short answer
Oklahoma: 4.5% state sales tax, about 8.98% average combined (rank 7 of 51 — 2.37 points above the 6.61% all-state average), a progressive income tax, and an average effective property tax of 0.9% (rank 25 of 51). On a $100 purchase at the average combined rate, the tax is $9.
Sales tax in Oklahoma
The statewide base rate is 4.5%. Counties, cities and special districts add their own layers, bringing the average combined rate to about 8.98% — and the rate at a specific address can sit well above or below that average. On a $100 purchase, the tax is $5 at the base rate and roughly $9 at the average combined rate. The difference is local tax, which is why two towns in the same state can charge noticeably different totals on the same item.
Oklahoma eliminated the 4.5% STATE grocery tax in August 2024; city/county grocery taxes still apply.
Worked examples at the average combined rate
What the 8.98% average combined rate adds to purchases of different sizes:
| Purchase | Tax | Total |
|---|---|---|
| $25 | $2 | $27 |
| $100 | $9 | $109 |
| $500 | $45 | $545 |
| $1,000 | $90 | $1,090 |
| $10,000 | $898 | $10,898 |
If you sell into Oklahoma from another state, economic nexus rules can oblige you to collect its tax once your sales pass the state's threshold — the exact threshold and what counts toward it are in the Oklahoma sales tax calculator and rate page, and the data hub for the state is the Oklahoma locations page.
Income tax in Oklahoma
Oklahoma taxes income progressively, in brackets, like the federal system. Progressive, top rate 4.75%. Because brackets tax slices of income at rising rates, your effective state rate is always below your top (marginal) rate.
Federal tax applies the same everywhere; the state layer is what changes a paycheck between two states. Run the same salary through the paycheck calculator and the take-home pay calculator with and without a state rate to see the size of the difference before negotiating a move or a remote-work arrangement.
Property tax in Oklahoma
The average effective property tax rate in Oklahoma is about 0.9% of a home's value per year. On a $400,000 home that is roughly $3,600 a year, or $300 a month — a real line in the housing budget, collected through escrow in most mortgages. Averages hide wide local variation: the county and school district set most of the rate, and homestead exemptions can cut the taxable value for owner-occupiers.

What this means for your money
Property tax in Oklahoma sits near the middle nationally: an average effective rate of 0.9% (rank 25 of 51; all-state average 1.04%). On a $400,000 home that is about $3,600 a year, or $300 a month through escrow. No single tax dominates the picture here — the state's overall position is the sum of three middling taxes rather than one extreme one.
Read together: Oklahoma combines an average combined sales tax of 8.98% (rank 7 of 51), an average effective property tax of 0.9% (rank 25 of 51) and progressive income tax brackets. A household comparing states should compare all three against its own pattern — a high earner who rents weighs the income tax most; a homeowner on a fixed income weighs the property tax most.
