Kansas State Income Tax: What You Need to Know
Kansas levies a state income tax on its residents. The state uses 3 brackets: 3.1%, 5.25%, 5.7% with a top marginal rate of 5.7%. This state tax is in addition to the federal income tax, which has seven brackets ranging from 10% to 37% for the 2026 tax year.

To calculate your total income tax burden in Kansas, you need to consider both federal and state taxes. Your federal tax is calculated on your taxable income after the standard deduction ($15,000 for single filers, $30,000 for married filing jointly in 2026). Your Kansas state tax is then calculated separately based on Kansas's own brackets and rules.
