Kansas Income Tax: Two Brackets, 5.2% and 5.58%

Kansas has used two income tax brackets since the 2024 reform (SB 1): 5.2% on the first $23,000 of Kansas taxable income ($46,000 married filing jointly) and 5.58% above that. Kansas taxable income is your income minus the Kansas standard deduction ($3,605 single, $8,240 married filing jointly, $6,180 head of household, $4,120 married filing separately) and the personal exemption ($9,160; $18,320 joint), plus $2,320 for each dependent.

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 42.58% on their highest dollars of income.

Kansas Tax Brackets for 2026 (Single Filer)

The Kansas income tax brackets for single filers, applied to Kansas taxable income, are:

• 5.2% on income from $0 to $23,000
• 5.58% on income over $23,000

Married couples filing jointly pay 5.2% on the first $46,000. Example: a single filer earning $60,000 has Kansas taxable income of $47,235 ($60,000 minus the $3,605 standard deduction and $9,160 exemption) and owes about $2,548: 5.2% on $23,000 plus 5.58% on $24,235.

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+). Kansas does not use the federal standard deduction; it has its own ($3,605 single), which this calculator applies together with the Kansas personal exemption.

Tips for Getting Accurate Results

For the most accurate results, use up-to-date numbers from official sources. Double-check your inputs before calculating — small errors in the starting values can lead to significantly different outputs. If you are comparing scenarios, keep all variables the same except the one you are testing. Save or screenshot your results for future reference. This calculator uses standard formulas and is designed to give you a reliable quick estimate, though professional advice may be needed for complex situations.
