Kansas Income Tax Calculator
Figure basis: Official Kansas Department of RevenueKansas income tax is calculated on your taxable income after deductions and exemptions. This calculator estimates your Kansas state income tax liability for the current tax year. Enter your annual gross income, choose your filing status (single, married filing jointly, married filing separately, or head of household), and add any pre-tax deductions to see your estimated state tax, effective tax rate, and marginal bracket. Results update in real time as you adjust your inputs. The calculator covers Kansas state income tax only; federal income tax, FICA payroll taxes, and any local income taxes your city or county imposes are separate. All rates and brackets are sourced directly from Kansas Department of Revenue and are verified for the current tax year. Use this tool alongside the federal income tax calculator to see your combined total tax liability. Effective rate and marginal rate are both shown so you can evaluate the impact of additional income, filing status changes, or increased pre-tax contributions to a 401(k) or similar plan.
Kansas uses graduated income tax brackets. A single filer earning $60,000 owes $3,059.39 in state income tax, an effective rate of 5.10% and a marginal rate of 5.58%. Enter your own income and filing status below.

How Kansas income tax works
During the 2024 Special Legislative Session, Kansas Senate Bill 1 amended KSA 79-32,110 to consolidate the individual income tax from three brackets to two, effective tax year 2024 and all tax years thereafter. It eliminated the former 3.1% bottom bracket, set a 5.2% rate on the first tier and a 5.58% top rate. For single, head of household and married filing separate filers, 5.2% applies to Kansas taxable income up to $23,000 and 5.58% above $23,000; for married filing jointly the thresholds are doubled to $46,000. SB 1 also raised the standard deduction and replaced the flat $2,250 personal exemption with filing-status-based exemptions. An earlier 2024 flat-tax bill, HB 2284, was vetoed by Governor Kelly; SB 1 in the June 2024 special session is the enacted law.

Kansas's two-bracket system and the flat tax that wasn't
Kansas nearly went flat and then did not. In 2024 the Legislature passed a flat-tax bill, HB 2284, that Governor Laura Kelly vetoed. The reform that actually became law, Senate Bill 1 from the June 2024 special session, kept a graduated structure but trimmed it from three brackets to two. It eliminated the old 3.1% bottom bracket and set just two rates: 5.2% and 5.58%.
For single, head of household, and married-filing-separately filers, 5.2% applies up to $23,000 of Kansas taxable income and 5.58% above it. Married couples filing jointly get exactly doubled thresholds, 5.2% up to $46,000 and 5.58% above. Because the two rates sit so close together, Kansas behaves almost like a flat tax in practice: a high earner's marginal rate is only 0.38 percentage points above someone near the bottom of the schedule.
SB 1 also reworked the offsets, and this is where real dollars hide. Kansas sets its own standard deduction, $3,605 single and $8,240 married filing jointly for 2025, and it replaced the former flat $2,250 personal exemption with filing-status-based amounts: $18,320 for a joint return, $9,160 for others, plus $2,320 per dependent. Those exemptions do heavy lifting at lower incomes, so the effective rate on a modest Kansas salary lands well under the 5.2% headline. None of these figures are indexed to inflation, so they hold until the Legislature acts again.
