Kansas Income Tax Calculator

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:

1. Gross wages: $75,000
2. Federal standard deduction: −$16,100 → federal taxable income: $58,900
3. Federal income tax (10%–22% brackets): ≈ $8,800
4. FICA: $75,000 × 7.65% = $5,738
5. Kansas standard deduction: −$3,500 → $71,500
6. Kansas personal exemption: −$2,250 → Kansas taxable income: $69,250
7. Kansas income tax: (5.2% × $23,000) + (5.58% × $46,250) = $1,196 + $2,581 = $3,777
8. Total taxes: $8,800 + $5,738 + $3,777 = $18,315
9. 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.

Retirement Income and Kansas Taxes

Kansas has retirement-friendly tax treatment for Social Security and public pension income:

• Social Security benefits — Kansas fully exempts Social Security benefits from state income tax for residents with federal adjusted gross income (AGI) at or below $75,000 (both single and married filing jointly). For taxpayers with AGI above $75,000, the portion of Social Security included in federal taxable income is also subject to Kansas income tax at the regular brackets (5.2%–5.7%). This means most Kansas retirees pay no Kansas tax on Social Security.
• KPERS pensions — Retirement income from the Kansas Public Employees Retirement System (KPERS) is fully exempt from Kansas income tax. This covers state and local government employees, teachers, and certain other public workers who participate in KPERS. KPERS distributions do not count toward the $75,000 AGI threshold for Social Security purposes.
• Private pensions and 401(k)/IRA distributions — These are taxable in Kansas at the regular brackets. A Kansas retiree receiving $40,000 from a private pension or 401(k) would owe Kansas income tax on that amount (after the standard deduction and personal exemption) at 5.2%–5.7%.
• Military retirement pay — Fully exempt from Kansas income tax for all Kansas military retirees.

Kansas Tax Credits and Deductions

• Kansas Earned Income Tax Credit (EITC) — Kansas provides a state EITC equal to 17% of the federal Earned Income Tax Credit, and it is refundable. This means eligible low- and moderate-income workers can receive the credit even if it exceeds their Kansas tax liability. For a single parent with one child earning $25,000, the federal EITC is approximately $3,995 — the Kansas EITC adds roughly $679. The credit is claimed on Form K-40.
• Personal exemption — $2,250 per taxpayer and per qualifying dependent. This is a direct reduction to Kansas taxable income, not a credit. A family of four reduces taxable income by $9,000 in personal exemptions alone.
• Kansas Learning Quest 529 Deduction — Contributions to the Kansas Learning Quest 529 education savings plan are deductible from Kansas taxable income up to $3,000 per beneficiary per year (single) or $6,000 per beneficiary (MFJ). At the 5.7% top rate, a $3,000 contribution saves $171 in Kansas state tax.
• Itemized deductions — Kansas allows itemized deductions based on federal Schedule A amounts (with Kansas-specific modifications). If your federal itemized deductions exceed the Kansas standard deduction ($3,500 single / $8,000 MFJ), itemizing for Kansas can reduce your state tax burden.

Kansas State Tax Return — Form K-40 and Filing Deadline

Kansas residents file their state income tax return on Form K-40 (Kansas Individual Income Tax Return). The Kansas filing deadline is April 15, the same as the federal return. Kansas grants an automatic six-month extension to file (to October 15), but any tax owed must be paid by April 15 to avoid interest and penalties. Use Form K-40V to make a payment with an extension.
