Two brackets since Senate Bill 1
The 2024 special session’s Senate Bill 1 replaced Kansas’ three brackets with two: 5.2% on the first $23,000 of taxable income ($46,000 for a joint return) and 5.58% above. The 2025 Form K-40 schedule turns that into a one-line computation — 5.58% of taxable income minus $87 for single filers, minus $175 for couples.
For a $1,000,000 Kansas prize and no other income, Kansas tax is $55,713. Kansas’ withholding guide (KW-100) sets withholding on gambling proceeds at 5% of the winnings less the bet, or $50,000 here, so roughly $5,713 of Kansas tax remains.
Missourians and Coloradans who win in Kansas
Kansas computes a nonresident’s tax by figuring the tax on all income as if the filer lived in Kansas and multiplying it by the Kansas share of income — the “nonresident percentage” on Form K-40. When the prize is most of the year’s income, that share is close to 100%, so a Missouri commuter who wins in Kansas City, Kansas owes Kansas almost what a resident would. The calculator approximates this by taxing the prize alone at Kansas rates.

What Kansas winners should know
- Kansas taxes nonresidents by computing tax on all income and multiplying by the Kansas share (the nonresident percentage on Form K-40).
- Kansas withholds 5% but its top rate is 5.58%, so a large prize usually leaves 0.58% to pay at filing.
