Oklahoma County Treasurer's
General Information


The Oklahoma County Assessor determines property values and provides notification of valuation. If you have any questions concerning your assessment, please contact the County Assessor's Office at 713-1200.


If you are a new owner of a property, you should contact the County Assessor's office with the correct address to send the statement before September 30. As they will certify the accounts to our office on October 1.


If your mortgage company is responsible for payment of your real estate taxes, as soon as we receive payment and post your account, it will immediately reflect paid on our web site. Most mortgage companies use a third party tax service company. This means your mortgage company remits payment to the tax service company who in turn submits payment to us for all mortgage companies they service. If your tax does not show paid and your mortgage company states they remitted payment for your taxes most likely the payment went to a tax service.


Failure to receive a statement is not a legal reason for waiving interest. The Treasurer must assess interest on all delinquent payments at a rate of 18% per year, added monthly on the 15th day of each month, at a rate of 1.5%.


Your property taxes may be paid in full or in two installments:

The one half or the full amount must be paid by December 31st. If nothing is paid by December 31st, then the full amount becomes delinquent January 1st and interest is added. We can not accept first half payment after the December 31st due date. If you choose to pay the first half payment on December 31st, then the last half becomes due on March 31st.
