How Oklahoma taxes wages

Brackets consolidated and the top rate cut to 4.5% for 2026.

At $65,000 of wages, that is the 23rd-lowest estimated bill of the 42 jurisdictions (including DC) that tax wages.

Its top rate of 4.5% is the 24th-highest among the 26 jurisdictions with progressive brackets.

Rates range from 2.5% to 4.5%. We don’t list the full bracket schedule here yet; for exact thresholds, see the official Oklahoma tax agency website.

Example: $65,000 salary, single filer

State income tax on a $65,000 salary
Wages$65,000
Income not taxed (approx. deduction, exemptions, 0% bracket)−$7,350
Income taxed$57,650
Average rate used for the estimate× 4.1%
Estimated Oklahoma income tax$2,364

That works out to about $197 a month, or an effective rate of 3.64% of wages.

Does Oklahoma tax tips and overtime?

Oklahoma does not follow the federal tips and overtime deduction. Form 511 starts from federal AGI, and Schedule 511-A has no subtraction for tips or overtime. The 2026 tax law only changes the brackets.

Qualified tips and overtime you deduct on your federal return (Schedule 1-A) are still taxed by Oklahoma, and our estimate taxes your full wages.
