Oklahoma property tax deadlines

7 sourced dates. 77 of 77 Oklahoma counties have at least one.

Oklahoma sets its dates in state law, and county treasurers mail bills in November. Taxes are due November 1, and you have to pay at least half before January 1, or the whole year's tax is late from that day. If you paid half in time, the rest is due before April 1. Homestead exemptions go to the county assessor by March 15.
