Kansas Income Tax Calculator

Kansas has two rates, 5.2% and 5.58%, and the higher one starts at just $23,000 of taxable income for a single filer, so most full-time workers pay 5.58% on their last dollar. A single filer earning $80,000 owes about $3,664 for 2026. The rates are unchanged from 2025; a 2025 law ties further cuts to state revenue, and the first test found no cut.

What's different about Kansas income tax

Two brackets since 2024

Senate Bill 1, passed in the 2024 special session, set two brackets: 5.2% on the first $23,000 of taxable income for single filers ($46,000 joint) and 5.58% above. It also raised the standard deduction to $3,605 single and $8,240 joint, and the personal exemption to $9,160 ($18,320 joint). Together they untax the first $12,765 of a single filer's income.

Rate cuts now depend on revenue

Senate Bill 269 (2025) cuts rates automatically in any year that general fund revenue beats its inflation-adjusted 2024 level and the rainy-day fund holds at least 15% of the prior year's tax receipts. Cuts apply to both individual rates proportionally until the lower one reaches 4%. The first review, on August 15, 2025, found fiscal 2025 revenue about $88.5 million short, so 2026 rates didn't change.

Social Security and public pensions are exempt

Kansas subtracts all Social Security benefits included in federal income. It also exempts federal civil service and military retirement, KPERS and other Kansas public pensions, and railroad retirement. Private pensions, 401(k) plans, and IRAs are taxed.

More exemptions for families

Each dependent adds a $2,320 exemption. From 2025 heads of household get an additional $2,320, and so does a family with a child born during the year, or a stillbirth for which a certificate is issued. The Kansas earned income tax credit is 17% of the federal credit and is refundable.

Kansas tax credits (2025 returns)

Credits come off the tax itself, after the brackets. The calculator applies only the ones marked; the rest depend on your family and income, so subtract any you qualify for from the estimate.

Credit Amount Who gets it In calculator
Earned income tax credit 17% of the federal EITC; refundable Residents who claim the federal EITC No
Dependent exemption $2,320 per dependent, plus $2,320 for heads of household and for a child born in the year Filers with dependents No

How Kansas Income Tax Compares to Neighboring States

Total income tax (federal + state) on a $100,000 annual salary in 2026, single filer using the standard deduction:

State State Tax Total Income Tax vs. Kansas
Kansas (here) $4,780 $17,950 —
Nebraska $3,670 $16,840 -$1,110
Colorado $3,692 $16,862 -$1,089
Oklahoma $3,955 $17,125 -$826
Missouri $3,670 $16,840 -$1,110

A negative "vs." figure means that state collects less total income tax than Kansas. Federal portion is identical across states; only state tax varies.
