Who sends the property tax bill in Oklahoma County, and how do you pay it?
The bill comes from the Oklahoma County Treasurer. The value it is based on is set by a separate office, the Oklahoma County Assessor, which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.
The Assessor sets values and handles exemptions, which must be filed by March 15; the Treasurer sends the statement and takes payment at 320 Robert S. Kerr Avenue, Suite 307, in Oklahoma City. Card payments are accepted online only and carry a convenience fee that goes to the payment provider, not the county. Most mortgage companies pay through a separate tax service company, so an escrow payment can take a while to reach the county; it shows on the county's website once the Treasurer posts it.
When are property taxes due in Oklahoma County?
For the 2026 bill, Oklahoma County splits the bill into 2 payments, the first due December 31, 2026 and the last March 31, 2027. The Treasurer adds interest on delinquent taxes at 1.5% a month (18% a year), added on the 15th of each month. Under state law, interest stops growing once it equals the unpaid tax.
| Payment | Due | Note |
|---|---|---|
| First half (or full payment) | December 31, 2026 | Under state law, taxes become due on November 1. Pay the full bill or at least the first half by December 31, 2026 (a Thursday). If nothing is paid by December 31, the whole year's tax becomes delinquent on January 1 and interest is added, and the county will not accept a first-half payment after December 31. Not receiving a statement does not excuse interest. |
| Second half | March 31, 2027 | Only if the first half was paid by December 31. March 31, 2027 is a Wednesday. Under state law the half-payment option is not open to mortgage companies paying from escrow, which must pay the whole year before January 1, or to bills of $25 or less, which are due in full before January 1. |
