What is the top income tax rate in Oklahoma for 2025?

The top marginal Oklahoma income-tax rate for 2025 is 4.75%, which applies only to taxable income in the highest bracket — not to your whole income. Lower brackets are taxed at lower rates. (Source: Tax Foundation 2025; Oklahoma Tax Commission.)

Are these the only taxes on my income?

No. These are Oklahoma state income-tax brackets only. On top of state tax you also owe federal income tax and FICA (Social Security + Medicare), and some cities or counties levy their own local income tax. This page covers the state schedule for the 2025 tax year.
