Missouri Capital Gains Tax 2026: Graduated income tax (top rate up to 4.8%)

Missouri capital gains tax planning starts with the federal rules, then layers on Missouri's own treatment (graduated income tax (top rate up to 4.8%)). This calculator estimates both so you can see a combined effective rate before you sell stocks, crypto, real estate, or other capital assets.

Federally, short-term gains (held one year or less) are taxed as ordinary income, while long-term gains generally use 0%, 15%, or 20% preferential rates for tax years 2025 and 2026. High earners may also owe the 3.8% Net Investment Income Tax when MAGI exceeds the IRS threshold for their filing status.

Missouri generally taxes capital gains under its graduated income-tax framework. For planning estimates we apply Missouri's top modeled rate (graduated income tax (top rate up to 4.8%)) to taxable gains. Your actual marginal state rate may be lower depending on total Missouri taxable income.

Missouri is modeled as graduated income tax with a top rate up to 4.8% on taxable capital gain. That top rate is what the state line uses, not a separate Missouri long-term schedule.

Federal 0%, 15%, and 20% brackets are computed first. Missouri’s 4.8% top rate is then applied to the taxable gain that remains after those federal asset rules. A filer in a lower Missouri bracket can owe less than this top-rate estimate.
