No, State law requires the Assessor’s Office to contact property owners via the USPS.

5. How are tax rates set for my property?

Tax rates or millage levies are set by procedures established in the Oklahoma Constitution or voted directly by the taxpayers. Rates are not set by the County Assessor. There are over 75 different rates in Oklahoma County and those vary across the county depending on which school district, city limit and vocational-technical school district the property is located. The tax or millage rate levied against a property makes a great deal of difference in the taxes paid. Rates in Oklahoma County have varied from $75 to $134 per thousand.

6. What is a mill?

A mill is one-thousandth of a dollar. For convenience in Oklahoma, a tax rate (the sum of all mills levied) is expressed as dollars per thousand dollars of assessed value. A Tax rate of 80 mills, for example, would be 80 tax dollars.

7. Where does my property tax money go?

Property taxes are an important source of revenue for local schools, vocational-technical education, libraries, city and county government. As in most states in the United States, property taxes are the backbone of funding of local government and schools. Oklahoma’s property tax with some changes has fulfilled this basic function since statehood. For additional information view the Tax Dollar Breakdown page.

8. When do I pay my tax?

The County Treasurer sends out a tax bill in October each year. Taxes may be paid on two installments. If exactly one half is paid by December 31, then the last half is due by March 31. If nothing is paid by December 31, the full amount is due and becomes delinquent January 1 with applicable penalties owed.
