What are the Kansas state income tax rates for 2025 and 2026?

Kansas uses a two-bracket progressive system in 2026: 5.2% on the first $23,000 of Kansas taxable income (single filers) and 5.58% on all income above $23,000. For married filing jointly, the 5.2% bracket extends to $46,000. These rates replaced a three-bracket system that previously included a lower starting rate — the state consolidated and adjusted its brackets as part of recent tax reform.

What is the Kansas standard deduction and personal exemption?

Kansas allows a standard deduction of $3,500 (single), $8,000 (married filing jointly), $4,000 (married filing separately), and $6,000 (head of household) for 2026. In addition, Kansas provides a $2,250 personal exemption per taxpayer and per dependent. Combined, a single filer with no dependents reduces Kansas taxable income by $5,750 ($3,500 + $2,250) before brackets apply.

How much annual income tax does a $75,000 Kansas single filer owe?

A single filer earning $75,000 in Kansas in 2026 owes approximately: $8,800 in federal income tax (after $16,100 federal standard deduction), $5,738 in FICA, and roughly $3,775 in Kansas state tax (after $3,500 deduction + $2,250 exemption, applying 5.2% × $23,000 + 5.58% × $46,250). Total annual taxes: roughly $18,313, an effective total rate of about 24.4% of gross income.

Does Kansas recognize 401(k) pre-tax contributions?

Yes. Kansas fully recognizes traditional 401(k), 403(b), and IRA pre-tax contributions — they reduce Kansas taxable income exactly as they reduce federal taxable income. At the 5.58% top Kansas rate, a $10,000 401(k) contribution saves $558 in Kansas state tax plus federal savings. At the 22% federal bracket, the combined saving is $2,158 per $10,000 contributed.

How does Kansas compare to Missouri and Oklahoma for income tax?

Kansas (5.2%–5.58%) is broadly comparable to Missouri (4.7% top rate) and Oklahoma (0.25%–4.75% progressive). A $75,000 single filer pays roughly $3,775 in Kansas state tax vs. about $2,800 in Missouri and about $2,600 in Oklahoma. However, Kansas City, Missouri residents also owe a 1% city earnings tax, and Missouri's brackets start at a lower income — so cross-border comparisons require checking city taxes too.

How is the annual Kansas income tax calculator different from the paycheck calculator?

This calculator estimates your full-year annual tax liability — federal plus Kansas state combined for the whole year — useful for tax planning, comparing states, and estimating what you owe at filing time. The paycheck calculator shows per-paycheck withholding and take-home pay by pay frequency. Use both together for a complete view of your Kansas tax burden.

Kansas Income Tax Calculator 2025 & 2026

Estimates Kansas state income tax (5.2%–5.58%), federal income tax, and FICA for 2025 and 2026 — two brackets, $3,500 standard deduction, $2,250 exemption.

How to Use This Kansas Income Tax Calculator

This Kansas income tax calculator estimates your annual KS state and federal tax liability for 2025 and 2026. Enter your gross wages, filing status, and any deductions above. Kansas applies two progressive brackets — 5.2% on the first $23,000 and 5.58% above — after a $3,500 standard deduction and $2,250 personal exemption (single filers). For per-paycheck withholding estimates, use the Kansas paycheck calculator.

How Kansas State Income Tax Brackets Work

Kansas uses two progressive brackets in 2026 — a simplification from the earlier three-bracket structure. Only income above each threshold is taxed at the higher rate:

5.20% on the first $23,000 of Kansas taxable income (single); $46,000 for married filing jointly
5.58% on all Kansas taxable income above those thresholds

Kansas taxable income is calculated as gross wages minus pre-tax deductions, minus the Kansas standard deduction ($3,500 single / $8,000 MFJ), minus personal exemptions ($2,250 per taxpayer and dependent). The Kansas standard deduction is notably smaller than the federal deduction ($16,100 single in 2026), so a higher share of your income is subject to Kansas tax compared to federal tax.

Step-by-Step Example — $75,000 Kansas Single Filer (2026)

Full annual tax calculation for a single Kansas resident earning $75,000:

Gross wages: $75,000
Federal standard deduction: −$16,100 → federal taxable income: $58,900
Federal income tax (10%–22% brackets): ≈ $8,800
FICA: $75,000 × 7.65% = $5,738
Kansas standard deduction: −$3,500 → $71,500
Kansas personal exemption: −$2,250 → Kansas taxable income: $69,250
Kansas income tax: (5.2% × $23,000) + (5.58% × $46,250) = $1,196 + $2,581 = $3,777
Total taxes: $8,800 + $5,738 + $3,777 = $18,315
Annual net income: $75,000 − $18,315 = $56,685

Kansas Personal Exemption and Deductions

Kansas offers a $2,250 personal exemption per taxpayer and per qualifying dependent — a feature not all states provide. This directly reduces Kansas taxable income before brackets apply. A married couple with two children claims $9,000 in exemptions ($2,250 × 4 people) plus the $8,000 MFJ standard deduction, reducing taxable income by $17,000 before a single dollar is taxed.

Unlike states such as Idaho or Colorado, Kansas does not mirror the federal standard deduction — its $3,500 single deduction is about one-fourth of the federal $16,100. This means Kansas taxpayers with higher incomes pay Kansas tax on a larger base than their federal taxable income would suggest. Use the general income tax calculator to compare Kansas against other states.

How to Reduce Your Kansas Annual Tax Liability

Maximize traditional 401(k) contributions — the 2026 limit is $23,500 ($31,000 if age 50+). At 5.58% Kansas + 22% federal = 27.58% combined marginal rate, every $1,000 contributed saves $275.80.
Contribute to an HSA — $4,300 (self-only) or $8,550 (family) in 2026. Reduces both federal and Kansas taxable income.
Claim all dependent exemptions — each qualifying dependent reduces Kansas taxable income by $2,250. Verify dependents are properly listed on your Kansas K-40 return.
Kansas Learning Quest 529 deductions— Kansas residents can deduct contributions to the state's Learning Quest 529 program up to $3,000 (single) or $6,000 (MFJ) per beneficiary from Kansas taxable income.
Itemize when beneficial — Kansas allows itemized deductions using Schedule A amounts (with some Kansas-specific modifications). If your federal itemized deductions exceed $3,500 (single), itemizing for Kansas as well can reduce state tax.

Kansas Has No Local Income Tax

Kansas levies no city or county income tax on wages. Workers in Wichita, Overland Park, Topeka, and all other Kansas cities pay only state and federal income tax. This matters especially for Kansas City metro workers — Kansas City, Missouri imposes a 1% earnings tax on wages earned or lived within its limits, so KS-side residents commuting into Missouri-side Kansas City may owe that 1% to Missouri while paying no local tax on Kansas earnings. Use the Kansas paycheck calculatorfor a per-paycheck breakdown of what's withheld from each check.
