Income Tax in Kansas
Kansas (KS) has 3 income tax brackets ranging from 3.1% to 5.7% for tax year 2025. The standard deduction is $3,500 for single filers and $8,000 for married filing jointly.
Kansas runs a low-rate income tax. The top marginal bracket sits in the bottom band of the U.S. state-tax distribution, and the effective rate paid by typical households is correspondingly modest. State revenue mixes income tax with sales and property taxes.
For households comparing Kansas against other states, the full picture combines income tax (modeled by the calculator) with state and local sales tax, property tax, and any state-specific tax preferences. The compare tool on this site runs a side-by-side total-burden estimate; the per-state pages cover the income-tax piece in detail.
TaxCompare answers state and federal tax questions using the IRS Revenue Procedures and the Tax Foundation state-tax database — the authoritative current-year statutory sources. Every numeric answer on the site uses current-year brackets, deductions, and rates as published by those sources.
Two things to know. First, statutory rates and effective rates are different. A 6 percent state with deductions and credits can produce a lower effective tax than a 4 percent state with no deductions. The compare tool runs effective-rate calculations. Second, multi-state filers (work in one state, live in another) have residency rules the tool does not currently model; the output reflects single-state residence.
How Kansas Income Tax Works
Kansas uses a progressive bracket structure for tax year 2025, with 3 marginal brackets ranging from 3.1% on the first dollar of taxable income to 5.7% at the top of the schedule. Each bracket rate applies only to the portion of income that falls within that bracket — your effective rate (total tax divided by taxable income) is generally lower than your top marginal rate.
Kansas's standard deduction is $3,500 for single filers and $8,000 for married filing jointly. The deduction is subtracted from gross income before bracket rates are applied; itemized deductions can be used instead when they exceed the standard amount.
Compared to flat-rate states, Kansas's graduated structure shifts more of the burden to higher earners. Compared to states with no income tax, Kansas residents face an explicit state income tax line — but typically lower sales and property tax rates as a partial offset. The Tax Foundation publishes annual state-and-local total tax burden comparisons that combine all three.

What This Page Cannot Tell You
The brackets and deductions above describe the statutory state-level rules. Your actual state tax liability depends on credits (earned-income credit, child credit, dependent credit), itemized deductions, retirement-income exclusions, local-government taxes (city or county income tax in some states), and federal taxable-income conformity rules. None of those interactions are computed here.
