A home in Oklahoma County is typically taxed around 1.05 percent of its market value for the 2025 tax year. Across Bethany, Del City, Edmond, Midwest City and the rest of the county the figure moves between 0.90 and 1.20 percent, so the range is what to plan against rather than the midpoint.
Oklahoma taxes a fraction of value, not the whole thing. Oklahoma County assesses at 11 percent of fair cash value, so a $350,000 home there is assessed near $38,500 and the millage rate is applied to that, which is how the bill lands at roughly 1.05 percent of what the home is actually worth. Because the ratio is set county by county, the same home assessed in a 12 percent county would start from a higher base.
The homestead exemption comes off that assessed figure rather than market value, so in Oklahoma County it is worth on the order of $110 a year rather than the large reduction a Texas owner would see.
Oklahoma County assesses at 11 percent of fair cash value and covers Oklahoma City, Edmond and the inner suburbs. Because Oklahoma City crosses county lines, two homes with the same mailing city can answer to different county assessors.
At the 1.05 percent Oklahoma County figure, with the homestead column assuming this is your primary residence. A parcel at the top of the county's 1.20 percent end would run roughly 14 percent higher than these.

A typical combined rate in Oklahoma County runs about 1.05 percent of market value for the 2025 tax year, and rates across the county range roughly 0.90 to 1.20 percent depending on which city and school district a property sits in. Oklahoma applies an assessment ratio to fair cash value and then applies millage, so the effective rate on market value is lower than the millage figure suggests.
