Kansas Capital Gains Tax Calculator
Kansas taxes capital gains as ordinary income at the state level, which means a gain on selling shares, property or other investments is added to your other income and taxed using the Kansas income tax brackets, with no separate preferential long-term rate like the federal system provides. This calculator estimates the Kansas state tax on a capital gain by stacking the gain on top of your other taxable income and applying the sourced Kansas Department of Revenue brackets for tax year 2024, then taking the difference. Enter your gain, your other annual taxable income and your filing status to see the state tax attributable to the gain and the effective rate on it. The result is the Kansas state portion only; federal capital gains tax, which has separate short-term and long-term rates set by the IRS, is calculated separately. Because the gain stacks on your other income, the same gain is taxed at a higher rate the more you already earn. Some states provide specific exclusions or preferential treatment for certain gains; this tool uses the standard ordinary-income method and links the Kansas Department of Revenue so you can confirm any special rule that applies to you.

Has Kansas been trying to move to a flat income tax?
Yes. The Kansas Legislature passed a flat-tax bill in 2024 that would have created a single rate, but Governor Laura Kelly vetoed it. HB 2284, which was enacted, instead reduced the top rate from 5.7% to 5.58%. Flat-tax proposals have been a recurring debate in Kansas since the 2012-2017 tax experiment that led to budget shortfalls.
Are there future rate reductions scheduled for Kansas?
As of tax year 2024, Kansas has no automatic future rate reductions written into statute following the enactment of HB 2284. Any further changes require new legislation. The Kansas Legislature continues to debate additional rate cuts or a flat-tax structure.
