A single filer earning Kansas's median household income of $87,690 owes about $4,093 in Kansas state income tax — an effective state rate of 4.67%. That is state tax only, on top of federal income tax and FICA.

Based on 2026 Kansas rules and 2026 federal rules, with the standard deduction and no other adjustments. Median income is the 2024 Census figure.

Income tax in Kansas

Kansas's 2024 reform consolidated its brackets into two: 5.2% on the first $23,000 of taxable income ($46,000 married filing jointly) and 5.58% above — unchanged for 2025 and confirmed unchanged again for 2026. It pairs a modest standard deduction with an unusually large personal exemption ($9,160 single / $18,320 joint). A trigger law can ratchet rates toward 4% in future years, but the budget certification required to trigger a cut was not made for 2026.

Kansas income tax structure (2026)

Kansas uses 2 progressive brackets on income above a $3,605 standard deduction (single) plus a $9,160 personal exemption. Single-filer brackets:

$0 – $23,0005.20%
over $23,0015.58%

Married-filing-jointly thresholds differ (roughly double in most states). Each slice of income is taxed at its own rate — landing in a bracket does not tax your whole income at that rate.

Common questions

What are Kansas's income tax brackets?
Kansas has just two brackets for 2026: 5.2% on the first $23,000 of taxable income for a single filer, and 5.58% on everything above that. Taxable income here is your pay after a $3,605 standard deduction ($8,240 joint) and a $9,160 personal exemption per filer. Joint filers get their own, wider thresholds.
What is the top income tax rate in Kansas?
5.58%, and it begins at $23,000 of taxable income for a single filer — about $35,765 of gross pay, once the $12,765 Kansas subtracts first is added back. Only income above that point is taxed at that rate; everything below it is taxed in the lower bands.
What is the tax bill on $87,690 in Kansas?
A single filer on Kansas's $87,690 median household income (2024 Census figure) owes roughly $4,093 to Kansas — an effective state rate of 4.7% against a 5.58% marginal bracket — plus about $10,462 of federal income tax.
Does Kansas have a personal exemption?
Yes — $9,160 per filer, or $18,320 on a joint return, subtracted before the brackets apply. It is larger than Kansas's own standard deduction ($3,605 single), so the exemption does most of the sheltering.

Estimates for general informational purposes only; not tax advice. Kansas figures are simplified (credits, local taxes, and AGI adjustments vary) and should be verified with the state Department of Revenue. Kansas's two-rate 5.2%–5.58% schedule is applied with the $3,605 standard deduction and $9,160 personal exemption for a single filer — not itemized deductions, exemption phase-outs, or any Kansas tax credit. It also excludes any local, county, or school-district tax your municipality may add.
