What is the property tax rate in Oklahoma City?

Oklahoma City's effective property tax rate is roughly 1.07% of market value. That results from Oklahoma County's 11% assessment ratio applied against local millage of about 97 mills, which is why the headline millage looks much larger than the effective rate.

How does the 11% assessment ratio work?

Oklahoma assesses residential property at 11% of its fair market value. So a $250,000 home has an assessed value of $27,500, and the millage rate is applied to that assessed value, not the full market value.

What does the homestead exemption save me?

The homestead exemption removes $1,000 of assessed value for an owner-occupied primary residence. At about 97 mills, that saves roughly $97 per year. The tool subtracts it before computing tax and reports the savings.

Why does the calculator show an effective-rate cross-check?

Because millage and assessment ratios are easy to mis-enter, the tool also estimates tax at OKC's known ~1.07% effective rate of market value. If the two figures are close, your millage and ratio inputs are reasonable.

Will my actual bill match this estimate?

Closely, but not exactly. Total millage varies by school district, municipal boundaries, and voter-approved bond levies, and additional exemptions like the senior valuation freeze can apply. Treat the result as a solid planning estimate.

Oklahoma City property tax looks intimidating because the millage rate is a large number, but the effective rate on market value is only about 1.07%. This estimator runs the real Oklahoma calculation — an 11% assessment ratio, local millage, and the homestead exemption — and cross-checks it against that effective rate so you can trust the figure.

How it works

Oklahoma taxes a fraction of your home’s value, then applies millage to that assessed amount:

assessed value = market value × 11% assessment ratio
taxable value  = max(assessed − homestead exemption $1,000, 0)
annual tax     = taxable value × (millage / 1000)

cross-check    = market value × 1.07% effective rate

A “mill” is one dollar of tax per $1,000 of assessed value, so 97.3 mills means $97.30 per $1,000 assessed. Because only 11% of market value is assessed, the effective burden on the full home value stays near 1.07%.

Example

A $250,000 home has an assessed value of $27,500. With the homestead exemption the taxable assessed value is $26,500; at 97.3 mills the annual tax is about $2,578 — roughly $215/month and close to the $2,675 cross-check at the 1.07% effective rate.

Notes

Total millage varies by school district, municipal boundaries, and bond levies, so adjust the millage field to your parcel. Additional relief such as the senior valuation freeze can lower your bill. This is a planning estimate; your county assessor’s statement is authoritative.
