Wyoming does not tax capital gains. There is no Wyoming personal income tax, so there is nothing at the state level to tax a gain — your Wyoming state capital gains tax is $0, whether the gain is short-term or long-term. You still owe federal capital gains tax — 0/15/20% on long-term gains under IRC §1(h), plus the 3.8% NIIT (§1411) for high earners — but nothing to the State of Wyoming. Compared with a state like California (up to 13.3%), a Wyoming resident can keep thousands more on the same sale.

Estimates only, for the 2026 tax year. Not tax advice. Wyoming imposes no state income tax, so the state figure is $0 with no thresholds to index; the federal figures used here are marked est. as projected 2026 amounts, owner-verifiable against the final IRS release.
Does Wyoming tax capital gains?
No. Wyoming is one of the handful of states with no personal income tax at all, and a capital gain is simply a form of income. With no income tax on the books, there is no mechanism — and no rate — for the state to tax a gain. Whether you sell stock you held for a week or a home you held for a decade, Wyoming collects $0 on the gain. That is true for short-term and long-term gains alike, because the distinction only matters federally.
This is not an exemption buried in the tax code; it is structural. Wyoming funds its government through mineral severance taxes, sales taxes, and property taxes rather than any tax on individual income. For an individual selling an appreciated asset, the only capital gains tax that applies is the federal one.
Why doesn't Wyoming tax capital gains?
Wyoming has never levied a personal income tax. Backed by mineral and severance revenue, the state has kept individual income untaxed, so there is no mechanism — and no rate — to tax a capital gain. Whether short-term or long-term, Wyoming collects $0 on the gain. Wyoming Department of Revenue — no personal income tax.
Because capital gains ride on the income-tax system, no income tax means no capital gains tax. There is no separate "capital gains" line for the state to fill in.
You still owe federal capital gains tax
Living in Wyoming removes the state tax, not the federal one. The IRS taxes a capital gain no matter which state you live in. For a long-term gain (asset held more than a year), you owe:
- Federal: 0%, 15%, or 20% depending on where the gain stacks on your taxable income, under IRC §1(h);
- Federal NIIT: an extra 3.8% on net investment income once MAGI passes $200,000 (single) / $250,000 (joint), under IRC §1411; and
- Wyoming: $0 — no state income tax.
A short-term gain (held one year or less) is worse federally, because the federal side taxes it as ordinary income (up to 37%) instead of at the 0/15/20% long-term rate. But even then, Wyoming adds nothing. The calculator above computes the federal layers and shows the exact bands used.
The one caveat people ask about: the federal tax on a home, stock, or crypto sale
The most common Wyoming question is some version of "I sold my house / my Tesla stock / my Bitcoin — do I owe capital gains tax?" The honest answer is: not to Wyoming, but yes to the IRS. Each of those is a federal taxable event:
- Home sale: the federal IRC §121 exclusion lets you exclude up to $250,000 of gain ($500,000 married filing jointly) on a primary residence you owned and used for two of the last five years — only gain above that is federally taxable. See our home-sale hub.
- Stocks: long-term gains at 0/15/20%; short-term as ordinary income.
- Crypto: the IRS treats crypto as property, so a sale or swap is a taxable disposal — see our crypto hub.
How this calculator works & where the numbers come from
No black box. The federal side uses the same unit-tested engine as our main calculator: net gain = proceeds − basis; classify by holding period; for long-term gains, subtract the standard deduction and stack the gain across the 0/15/20% bands per IRC §1(h); add 3.8% NIIT where modified AGI crosses the §1411 threshold; short-term gains are computed as the true marginal difference in ordinary tax. The Wyoming side is simple: Wyoming has no personal income tax, so the state tax is $0 with no brackets, thresholds, or deductions to apply. The total is therefore the federal amount alone.

Wyoming capital gains tax, answered
Does Wyoming have a capital gains tax?
No. Wyoming has no state income tax, so it does not tax capital gains. The state tax on your gain is $0, short-term or long-term. You still owe federal capital gains tax — 0/15/20% on long-term gains under IRC §1(h), plus 3.8% NIIT (§1411) for high earners — but nothing to the State of Wyoming.
Why doesn't Wyoming tax capital gains?
Because Wyoming has no personal income tax, and a capital gain is a form of income. The state has never enacted one, funding itself through mineral, sales, and property taxes instead. No income tax means no capital gains tax.
How much is capital gains tax in Wyoming for 2026?
Your total equals the federal tax only. A long-term gain is taxed federally at 0/15/20% under IRC §1(h), plus 3.8% NIIT if your MAGI exceeds $200,000 (single) or $250,000 (joint). The Wyoming state figure is $0, so a mid-income Wyomingite might pay roughly 15% federal and nothing more. Use the calculator above for your exact federal figure.
Do I still owe federal tax on a home, stock, or crypto sale in Wyoming?
Yes — living in Wyoming removes the state tax, not the federal one. Selling a home, stocks, or crypto at a profit is a federal taxable event. Long-term gains are taxed at 0/15/20%; short-term as ordinary income; the 3.8% NIIT applies for high earners. The federal §121 exclusion still shelters up to $250,000 ($500,000 joint) of gain on a primary residence.
Does the 3.8% federal NIIT apply to Wyomingites?
Yes — the NIIT is federal and applies in every state. Once modified AGI exceeds $200,000 (single) or $250,000 (married filing jointly), the 3.8% surtax under IRC §1411 hits the lesser of your net investment income or the amount over the threshold. Wyoming having no income tax does not exempt you from this federal surtax.
How does Wyoming compare to California on capital gains?
They are opposite extremes. Wyoming taxes gains at 0% at the state level — you pay federal only. California taxes gains as ordinary income from 1% up to 13.3% on top of the same federal tax. On a large gain, a California resident can pay well over 13% more than a Wyomingite on the identical sale. See our California hub for the contrast.

Wyoming is one of our no-income-tax state hubs — the same unit-tested federal engine, with the state layer set to its true value of $0. Every state page combines the federal number with that state's own rules, so you always see the full combined figure, not just half of it. Compare the extremes: California and New York tax gains heavily as ordinary income, while Florida, like Wyoming, adds nothing. Until your state's page is live, the main Capital Gains Tax Calculator lets you fold any state's top marginal rate into your federal receipt.
