Kansas State Income Tax Overview
Kansas imposes income tax using two brackets: 5.2% on income up to $23,000 for single filers and 5.58% above that. Senate Bill 1, enacted in June 2024 and retroactive to January 1, 2024, consolidated three brackets into two, cut the top rate from 5.7% to 5.58%, and eliminated the lowest bracket entirely. The same law raised the personal exemption sharply, from $2,250 to $9,160 for single filers and from $4,500 to $18,320 for married couples. The standard deduction is $3,605 for single filers and $8,240 for joint filers. Social Security income is exempt for residents with federal AGI below $75,000, military retirement pay is fully exempt, and a food sales tax credit offsets the state's grocery tax.

How accurate is this estimate?

Understanding Your Kansas Tax Estimate
Your results combine two separate bills: federal tax owed to the IRS, and Kansas state tax owed to the Kansas Department of Revenue. The state return is filed separately from your federal Form 1040, with a state filing deadline of April 15. For the mechanics of how bracket math actually works -- why your effective rate is almost always lower than your top bracket -- see our marginal vs. effective tax rate guide.
Lowering Your Kansas Bill
Pre-tax retirement contributions reduce your federal and Kansas taxable income in the same move -- see our 401(k) contribution limits and HSA limits guides for the current caps. Beyond that, Kansas-specific credits and deductions that don't exist at the federal level are listed at the Kansas Department of Revenue -- worth checking, since these are easy to miss if you only look at federal guidance.
Combined Sales + Income Tax Picture
Kansas's combined state-plus-average-local sales tax rate is 8.68%. If you're self-employed, that's an added layer on top of income tax -- our self-employment tax calculator covers the SE-specific piece separately.
