Kansas Income Tax: Graduated Brackets Up to 5.7%
Kansas uses a progressive income tax system with 3 brackets. Rates range from 3.1% to 5.7%, with higher income taxed at higher rates. Kansas has three tax brackets with a top rate of 5.7%.
Like federal taxes, Kansas's system is marginal — only the income within each bracket is taxed at that bracket's rate. Combined with federal taxes (10%–37%), Kansas residents can face a total marginal rate of up to 42.7% on their highest dollars of income.
Kansas Tax Brackets for 2026 (Single Filer)
The Kansas income tax brackets for single filers are:
- 3.1% on income from $0 to $15,000
- 5.25% on income from $15,000 to $30,000
- 5.7% on income over $30,000
Your marginal rate is the rate on your last dollar of income. Your effective rate (total tax divided by total income) is always lower because of the progressive structure.
Tips to Lower Your Kansas Tax
Maximize pre-tax retirement contributions to reduce both federal and Kansas taxable income. The 2026 401(k) limit is $24,500 ($32,500 with catch-up for age 50+). If Kansas conforms to federal deductions, your standard deduction and itemized expenses also reduce your state tax liability.
