Free Kansas Tax Calculator

Kansas keeps its income tax simple: two brackets for 2026. 5.2% on your first $23,000 of taxable income (single; $46,000 married filing jointly) and 5.58% on income above. Unlike most states, Kansas does NOT let you use the federal standard deduction — it has its own larger deduction of $12,765 single / $26,560 married (2026), plus a $9,160 personal exemption.

Run a $70,000 single salary through it: Kansas taxable income is $70,000 minus the $12,765 state deduction and $9,160 exemption, so $48,075. The first $23,000 is taxed at 5.2% ($1,196.00) and the remaining $25,075 at 5.58% ($1,399.19) — roughly $2,595 total, an effective rate of about 3.7% of gross.

Kansas is one of the states that still fully taxes Social Security benefits for higher earners, though seniors earning under $75,000 AGI get relief. The state levies no local income taxes — not even in Wichita, Topeka, or Kansas City (Kansas side) — so what you see in the brackets is what gets withheld.

Property tax averages a moderate 1.37%, and combined sales tax runs 8.66% on average thanks to substantial local add-ons — top-10 nationally. Worth noting: the Kansas City metro area has a peculiar situation where living in Kansas but working in Missouri (or vice versa) triggers credit rules between the two states, which the calculator handles only implicitly — check with your payroll department for that edge case.

Filing in Kansas: resident returns go to the Kansas Department of Revenue on Form K-40, due April 15 with your federal return. The state supports free online filing, and employer withholding follows your federal W-4 selections unless you file a separate Kansas K-4 to fine-tune it.
