Kansas imposes a graduated individual income tax with three brackets. For 2026, the rates are projected at approximately ~3.1%, ~5.25%, and ~5.7%, applying to progressively higher levels of taxable income. Kansas uses federal adjusted gross income as the starting point for calculating state tax, with several Kansas-specific modifications. The state also allows itemized or standard deductions and provides credits that can reduce the final liability. Kansas City-area residents should be aware that while Kansas itself has no local income tax, those working across the state line in Missouri may face reciprocity considerations.

How Kansas Income Tax Works

Federal AGI Starting Point

Kansas begins with federal adjusted gross income and applies Kansas-specific additions and subtractions. Common additions include interest on out-of-state municipal bonds. Common subtractions include Social Security benefits included in federal AGI and contributions to the Kansas 529 plan.

Standard Deduction and Exemptions

  • Standard deduction: ~$3,500 for single filers; ~$8,000 for married filing jointly
  • Personal exemption: ~$2,250 per person (taxpayer, spouse, and each dependent)
  • Itemized deductions: Kansas allows itemized deductions that generally conform to the federal Schedule A

Key Exclusions and Adjustments

  • Social Security: Exempt from Kansas income tax for filers with federal AGI of ~$75,000 or less; partially or fully taxable above that threshold
  • Military retirement: Fully exempt from Kansas income tax
  • Federal pension income: Taxable in Kansas
  • State and local tax refunds: Added back if deducted on the federal return

Tax Credits

  1. Child and dependent care credit: ~25% of the federal credit
  2. Earned income credit: Not available at the state level as of 2026
  3. Food sales tax credit: A refundable credit for lower-income households to offset sales tax on food, approximately ~$125 per person
  4. Disabled access credit: For small businesses making their facilities accessible
  5. Historic preservation credit: ~25% of qualifying rehabilitation expenditures

Who Must File in Kansas

You must file a Kansas return if:

  • You are a Kansas resident required to file a federal return
  • You are a nonresident or part-year resident with Kansas-source income
  • You want to claim a refund of Kansas withholding or the food sales tax credit

Kansas uses Form K-40 for all individual filers. The filing deadline is April 15.

Comparison to National Average

National average~4.60%Varies

Kansas’s top rate of ~5.70% is above the national average and higher than most of its immediate neighbors. However, the state’s relatively generous standard deduction and the food sales tax credit help moderate the effective rate for many filers.

Tips for Minimizing Kansas Income Tax

  1. Claim the food sales tax credit. This refundable credit of approximately ~$125 per person is available to lower-income households and offsets sales tax on food purchases.

  2. Verify Social Security exemption eligibility. If your federal AGI is ~$75,000 or less, your Social Security benefits should be fully exempt from Kansas tax.

  3. Contribute to a Kansas 529 plan. Contributions of up to ~$6,000 per beneficiary (or ~$12,000 for married filers) are deductible from Kansas taxable income.

  4. Maximize retirement contributions. 401(k) and traditional IRA contributions reduce your federal AGI, which directly lowers your Kansas starting income.

  5. Compare itemized vs. standard deductions. Kansas’s standard deduction is lower than the federal amount, so itemizing may provide greater benefit for some filers.

  6. Understand Kansas City border issues. If you live in Kansas but work in Missouri (or vice versa), review reciprocity rules to avoid double taxation.

  7. Claim the child and dependent care credit. Kansas allows ~25% of the federal credit, which is automatically calculated if you claimed the federal credit.
