Wyoming capital gains tax overview

Wyoming capital gains tax planning starts with the federal rules, then layers on Wyoming's own treatment (no state capital gains tax). 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.

Wyoming does not levy a state income tax on capital gains, so the state line on your estimate should be $0. Federal tax and NIIT can still apply. This makes Wyoming attractive for investors comparing after-tax outcomes across states, but moving solely for tax reasons involves many non-tax factors.

Wyoming figures in this model are drawn from the official source we cite for the state: https://revenue.wyo.gov/. Confirm the current-year statute or agency page before you file — rates and special rules can change.

Use the calculator above with filing status and income to stack federal long-term or short-term tax, NIIT, and Wyoming state tax. Compare nearby states from the links below, review our methodology for data sources (including Wyoming's official reference), and consult a CPA before filing.

FAQ

Wyoming FAQs

Does Wyoming tax capital gains at the state level?

No. Wyoming does not levy a state income tax on capital gains in our model, so the state line of your estimate is $0. Federal short-term and long-term capital gains tax, and the 3.8% Net Investment Income Tax when MAGI exceeds the IRS threshold, can still apply.

If I live in Wyoming, do I still owe federal capital gains tax?

Yes. Wyoming's $0 state tax does not change federal treatment. Ordinary rates apply to short-term gains; preferential 0%/15%/20% rates generally apply to qualifying long-term gains. Federal short-term and long-term capital gains tax, and the 3.8% Net Investment Income Tax when MAGI exceeds the IRS threshold, can still apply.

How should I use this Wyoming calculator?

Enter your buy/sell prices, dates, filing status, and other taxable income to estimate federal tax and NIIT. The Wyoming state amount should remain $0. Confirm residency and any local rules with a licensed CPA before filing.
