Oklahoma Property Tax Updates

UPDATED september 2025

Oklahoma Law Requires Timely Payment of Taxes Under Written Notice of Protest

Treasurers across Oklahoma will begin mailing 2025 tax bills in October. By law, the taxes are due by December 31st, but the taxpayer has the option of making two equal installment payments, one on December 31st and the other on the following March 31st.

If a taxpayer has a protest pending, it is imperative that the taxes be paid timely, with an accompanying written notice of protest on OTC Form 990 specifying the amount of tax being paid under protest. By law, the treasurer must escrow the disputed taxes pending outcome of the appeal.  Failure to pay timely, or failure to pay under notice of protest, subjects the taxpayer’s appeal to dismissal.
