About Oklahoma income tax
Oklahoma uses progressive tax brackets ranging from 0.25% up to 4.75%. Because the system is progressive, your first dollars are taxed at the lowest rate and only income above each threshold is taxed at the higher rates — so your effective rate is lower than the 4.75% top rate.
This page applies Oklahoma's published single-filer brackets to the income you enter. It doesn't include Oklahoma's own standard deduction, personal exemptions, or credits, which can lower your actual bill.
