How taxes work in Oklahoma
Sales tax. Oklahoma charges a 4.5% statewide sales tax, and counties, cities and special districts add their own on top — which is why the average combined rate of about 8.98% is the number that matters at the till. Oklahoma eliminated the 4.5% STATE grocery tax in August 2024; city/county grocery taxes still apply.
Property tax. At an average effective rate of about 0.9%, a $350,000 home in Oklahoma carries roughly $3,150 a year in property tax before exemptions. That is near the middle of US states. Local assessors set actual bills, so verify with the county for any specific property.
Income tax. Progressive, top rate 4.75%. If you are self-employed in Oklahoma, you still owe federal self-employment tax plus quarterly state estimates where applicable.

What this means for your money in Oklahoma
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.
