Alaska does not tax capital gains. There is no Alaska personal income tax, so there is nothing at the state level to tax a gain — your Alaska 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 Alaska. Compared with a state like California (up to 13.3%), a Alaska resident can keep thousands more on the same sale.

Does Alaska tax capital gains?
No. Alaska 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, Alaska 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. Alaska funds its government primarily through oil and gas severance taxes, federal transfers, and earnings from the Alaska Permanent Fund rather than any tax on individual income. There is no statewide sales tax either, though some municipalities levy local sales taxes. For an individual selling an appreciated asset, the only capital gains tax that applies is the federal one.
Why doesn't Alaska tax capital gains?
Alaska repealed its short-lived personal income tax in 1980 and has never reinstated one. Flush with oil, gas, and Permanent Fund revenue, the state has no individual income tax on the books — and therefore no mechanism, and no rate, to tax a capital gain. Whether the gain is short-term or long-term, Alaska collects $0. Alaska 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 Alaska 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
- Alaska: $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, Alaska 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 Alaska 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 Alaska, 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 Alaska side is simple: Alaska 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.

Alaska capital gains tax, answered
Does Alaska have a capital gains tax?
No. Alaska 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 Alaska.
Why doesn't Alaska tax capital gains?
Because Alaska has no personal income tax, and a capital gain is a form of income. Alaska repealed its personal income tax in 1980 and funds itself through oil and gas revenue and the Permanent Fund instead. No income tax means no capital gains tax.
How much is capital gains tax in Alaska 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 Alaska state figure is $0, so a mid-income Alaskan 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 Alaska?
Yes — living in Alaska 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 Alaskans?
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. Alaska having no income tax does not exempt you from this federal surtax.
How does Alaska compare to California on capital gains?
They are opposite extremes. Alaska 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 Alaskan on the identical sale. See our California hub for the contrast.

Alaska 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 Alaska, 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.
