Does Kansas have a special capital gains tax rate?

No. Kansas taxes capital gains as ordinary income with no preferential rate. Both short-term and long-term gains are added to your Kansas taxable income and taxed at the 2024 brackets of 3.1%, 5.25%, and 5.7%.

How are federal capital gains taxed?

Federal long-term gains (assets held over one year) use the 0%, 15%, or 20% rates depending on your total taxable income. Short-term gains (held one year or less) are taxed as ordinary income at your regular federal marginal rate.

What are the 2024 federal long-term capital gains brackets?

For 2024 single filers, the 0% rate applies up to $47,025 of taxable income, 15% up to $518,900, and 20% above that. For married filing jointly the breakpoints are $94,050 and $583,750. The gain itself counts toward where you land.

Does this include the 3.8% net investment income tax?

No. This calculator excludes the federal 3.8% Net Investment Income Tax (NIIT) that can apply to high earners, as well as capital losses and carryforwards. It models the federal capital gains tax plus Kansas's ordinary-income treatment of the gain.

Why does Kansas tax look higher than other states for gains?

Because Kansas gives no capital gains exclusion or preferential rate, a long-term gain is taxed at your full marginal Kansas rate just like wages. States that offer a partial exclusion would tax less of the same gain.

Kansas treats capital gains as ordinary income, so unlike the federal system there is no lower long-term rate at the state level. This calculator layers the federal capital gains tax — preferential for long-term holdings — on top of Kansas’s ordinary-income brackets to show your total bill.

How it works

The federal side depends on holding period:

Long-term  → 0% / 15% / 20% based on total taxable income (income + gain)
Short-term → taxed at your federal ordinary marginal rate

The Kansas side is simpler: the full gain is added to ordinary income and taxed at the 2024 brackets of 3.1 percent up to 15,000 dollars, 5.25 percent to 30,000 dollars, and 5.7 percent above that (single schedule). There is no state capital-gains exclusion.

Example

A single filer with 80,000 dollars of other income and a 40,000-dollar long-term gain lands in the federal 15 percent bracket, so federal tax is 6,000 dollars. Kansas taxes the 40,000 gain on top of ordinary income near the 5.7 percent marginal band, roughly 2,280 dollars, for a combined tax around 8,280 dollars.

Notes

This is an estimate, not tax advice. It excludes the 3.8 percent federal NIIT, capital losses and carryforwards, and the Kansas standard deduction and exemptions, which apply to your overall return rather than the gain in isolation. Confirm at irs.gov and ksrevenue.gov.
