Kansas Income Tax 2026 — Brackets and Credits
Kansas uses a 3-bracket graduated income tax system. The state's own standard deduction ($3,500/$8,000) is significantly lower than the federal standard deduction, which means more Kansas income is taxable than at the federal level. Personal exemptions ($2,250/person) further reduce the tax base.
Calculation Formula
KS Tax (brackets) = 3.1% / 5.25% / 5.7% applied progressively
Food Credit = $125 × persons (if income ≤ threshold)
KS Tax Final = max(0, Bracket Tax − Food Credit)
Example: Single filer, $60,000, 0 dependents
3.1% on $15,000 = $465
5.25% on $15,000 ($30K−$15K) = $788
5.7% on $24,250 ($54,250−$30,000) = $1,382
Total bracket tax: $2,635 | Food credit: $0 (above threshold)
KS Tax: $2,635 | Effective rate: 4.39%
