What to do next
How it works
The calculator starts from your income after pre-tax contributions, subtracts Oklahoma's standard deduction and personal exemptions where they exist, and applies a graduated state income tax with 4 brackets from 0% to 4.5%. Personal credits come off the tax. Oklahoma allows a standard deduction of $6,350 for single filers and a personal exemption of $1,000.
Things to keep in mind
Oklahoma has no local income taxes. Itemized deductions and state-specific credits are not applied, so filers with large deductions will owe less than shown.
Some Oklahoma rules, such as high-income phase-outs or special rates on certain income, are left out of this estimate. The state revenue department's own calculator or instructions have the full detail.
