Property taxes in Oklahoma

Homeowners in Oklahoma pay an average effective property tax rate of 0.79% of their home's value each year, the 26th highest of all 50 states and DC. On a $400,000 home that is about $3,160 a year, or $263 a month added to your mortgage payment.

Your actual bill depends on your county and city, local levies and any homestead exemption, so check the assessor's website for the exact rate before you buy.

Frequently asked questions

What is the property tax rate in Oklahoma?

The average effective property tax rate in Oklahoma is 0.79% of home value per year (Tax Foundation, 2026 edition, based on 2024 Census data). Rates vary by county, from 0.34% in Pushmataha County to 0.98% in Tulsa County.

What is the monthly payment on a $400,000 house in Oklahoma?

With 20% down and a 30-year loan at 6.5%, principal and interest is $2,023 a month. Adding Oklahoma's average property tax ($263) and home insurance ($150) brings the total to about $2,436 a month, before any HOA fees.

How much do I need to earn to buy a $400,000 home in Oklahoma?

Using the common rule that housing should be no more than 28% of gross income, a $2,436 monthly payment needs an income of about $104,000 a year. Lenders also look at your other debts (debt-to-income ratio).

Does Oklahoma have a homestead exemption?

Most states offer some form of homestead exemption or credit that lowers the taxable value of your main home. Check with your Oklahoma county assessor; you usually have to apply once after you buy.

How much house can I afford?

A common guideline is to keep your total housing payment (including taxes and insurance) under 28% of your gross monthly income, and all debt payments under 36%. Use the calculator to find a home price whose total monthly payment fits that range.

When does PMI go away?

On conventional loans you can usually request PMI removal once your balance reaches 80% of the original home value, and it is cancelled automatically at 78%. FHA loans have different mortgage insurance rules.
