Worked example (computed October 13, 2026)
A married couple in Alaska sells a rental building in Anchorage for $2,000,000 with $120,000 of selling costs and a $650,000 basis after $300,000 of depreciation; other income is $190,000. The gain is $1,230,000. All in one year the tax is $320,212: $275,752 federal, $44,460 net investment income tax and $0 Alaska tax, or 26% of the gain. Spread over 10 years on a note, the tax on the gain is $232,386, so they keep $87,826 more (interest on the note is taxed separately).
What applies in Alaska with no state tax on the gain
federal capital gains tax (0%, 15% or 20%) plus the 3.8% net investment income tax; no state income tax and no state real estate transfer tax; some boroughs and cities levy sales taxes that do not reach capital gains.

How Alaska treats capital gains
Alaska has no state income tax, so there is no Alaska capital gains tax. Your entire exposure is federal.
Because there is no state layer, everything comes down to federal treatment. That makes the timing of the sale, the 3.8% net investment income tax and depreciation recapture the whole game.
The three layers on a Alaska sale
Most sellers budget for one tax and get hit with four:
- Federal long-term capital gains at 0%, 15% or 20% depending on total taxable income for the year.
- Net investment income tax of 3.8% once modified AGI passes $200,000 single or $250,000 married filing jointly. Those thresholds are not indexed for inflation, so more sellers cross them every year.
- Depreciation recapture, if the asset was a rental or business property. The real-property portion is taxed at up to 25% as unrecaptured Section 1250 gain, and equipment is recaptured as ordinary income. See depreciation recapture.
- Alaska state tax: none. Alaska does not tax capital gains.
The result on a large sale is 23.8% federal, including the net investment income tax.
Why the year matters more than the rate
Every one of those layers is triggered by income landing in a single tax year. The federal rate steps from 0% to 15% to 20% based on taxable income. The 3.8% surtax switches on at a fixed threshold. For sellers 65 and older, the new $6,000 senior deduction begins phasing out at $75,000 of modified AGI ($150,000 joint) and is fully gone by roughly $175,000 ($250,000 joint), so a single large sale wipes it out completely.
Spreading the same gain across several years keeps each year's income lower, and each layer is calculated on that lower number. That is the entire mechanism behind an installment sale under IRC §453, and it is why two sellers with identical gains can pay very different totals.
Recapture is the exception: under §453(i) it is recognized in the year of sale regardless of how payments are structured.
What this actually costs: Alaska numbers
Take a $500,000 long-term gain, on top of $200,000 of other income, married filing jointly.
That is roughly 24% of the gain, all federal. Alaska takes nothing, so the federal timing levers are the only ones you have, and they matter more, not less.
If the asset was ever a rental or business property, add depreciation recapture: up to 25% on the real-property portion and ordinary rates on equipment.
The four layers, in the order they hit you
1. Federal capital gains. 0%, 15% or 20%, decided by your total taxable income for the year, including the gain itself. That is why one large sale lands people in the 20% bracket who normally sit far below it.
2. The 3.8% net investment income tax. Switches on above $200,000 modified AGI single, $250,000 married filing jointly. Those thresholds have never been indexed for inflation, so each year quietly captures more sellers.
3. Depreciation recapture. Only if you depreciated the asset. The real-property portion is unrecaptured Section 1250 gain at up to 25%; equipment is Section 1245 recapture at ordinary rates. The §1245 piece cannot be spread: §453(i) puts it in the year of sale. Unrecaptured §1250 gain on a building is spread with the payments.
4. Alaska tax. None. Alaska does not tax capital gains.
Who Alaska can tax, and on what
- Real property: no Alaska tax, but your home state may tax it. Alaska does not tax the gain. If you live in a state with an income tax, that state generally taxes your gain on Alaska property, and there is no Alaska tax to credit against it.
- Everything else generally follows residency on the date of sale: business interests, stock, collectibles.
Because Alaska has no income tax, there is no state withholding at closing and no non-resident return to file. Your entire exposure is federal.
Does spreading the sale help in Alaska?
Yes, for federal reasons rather than state ones. There is no Alaska tax to reduce, but the 3.8% surtax threshold and the step from the 15% to the 20% federal bracket are both annual tests. Spreading a $500,000 gain over five years can hold a seller in the 15% bracket and under the surtax in each of them, worth roughly $44,000 on these numbers.
An installment sale under IRC §453 spreads the gain across the years you actually receive payments, so every threshold above is tested annually instead of once.
The trade-offs deserve stating plainly: you need a buyer willing to pay over time, you carry collection risk, recapture still lands in year one, and large installment balances can trigger an interest charge under §453A. It fits some sales and not others, which is exactly what a conversation before closing is for.
Find out what your sale is really going to cost you in tax, and what you can do about it
No retainer. On a funded structure, the insurer pays a one-time commission of about 4% of the amount structured to the brokerage firm that places it (Hans’s share is about 2.4%; no trail). It is built into the annuity pricing, not a separate fee.

Frequently asked
Q: What is the Alaska capital gains tax rate? A: Zero. Alaska has no state income tax and therefore no state capital gains tax. Your exposure is federal only, up to 23.8% including the net investment income tax.
Q: Does Alaska have a lower rate for long-term capital gains? A: There is no Alaska capital gains tax at all, long-term or short-term.
Q: How do I calculate capital gains tax in Alaska? A: Start with your sale price minus your adjusted cost basis, which is what you paid plus improvements minus any depreciation you took. That gain is then subject to federal capital gains rates, potentially the 3.8% net investment income tax, depreciation recapture if it was a rental, and Alaska tax. The calculator on this site layers all four.
Q: Can I avoid Alaska capital gains tax by moving before I sell? A: Residency changes are scrutinised closely and the facts matter a great deal, including where you lived at closing and whether the asset is real property physically located in the state. Real estate is generally taxed by the state where it sits regardless of where you live. Talk to a CPA before relying on this.
