How it works

The calculator subtracts your pre-tax deductions, the larger of the standard deduction or your itemized amount, and Kansas’s personal exemptions ($9,160 for single/head-of-household/separate filers, $18,320 for joint filers, plus $2,320 per dependent) from gross income to get Kansas taxable income. Then it applies the three 2026 brackets: 3.1% on the first slice, 5.25% on the middle slice, and 5.7% on everything above. For single filers the slice edges are $15,000 and $30,000; for joint filers they’re doubled ($30,000 and $60,000). These rates have been in place since 2018.

Frequently asked questions

What are Kansas’s 2026 income tax brackets? Three graduated rates: 3.1%, 5.25%, and 5.7%. Single filers pay 3.1% on the first $15,000 of Kansas taxable income, 5.25% on the next $15,000, and 5.7% above $30,000. Joint filers get doubled thresholds ($30,000 and $60,000).

What is the 2026 Kansas standard deduction? $3,605 for single, $8,240 for married filing jointly, $4,120 for married filing separately, and $6,180 for head of household. Kansas sets these by statute, so they don’t rise with inflation automatically.

How do Kansas personal exemptions work? Kansas gives a personal exemption of $9,160 (single/head/separate) or $18,320 (joint), plus $2,320 per dependent. Combined with the standard deduction, a single filer shelters $12,765 from Kansas tax before the 3.1% rate even starts.
