Alaska Capital Gains Tax Calculator
Calculate capital gains tax in Alaska. State rate: 0%. See federal + state combined tax on stocks, property, and investments.
Estimate only — these are not official figures
Modeled estimate. Federal regular tax uses official 2026 IRS ordinary and long-term brackets, but assumes the entered transaction is a net gain eligible for the general rates and omits collectibles, unrecaptured section 1250 gain, section 1202 stock, home-sale exclusions, transaction costs, other gains/losses, and AMT. NIIT uses the entered MAGI and net-investment-income proxies. State tax is not a return calculation: Alaska has no broad individual income tax, so this calculator uses a 0% state default. It does not test residency, sourcing, entity-level taxes, or unusual asset-specific taxes.
Do not rely on these amounts for budgeting or payment. For exact amounts, check the Alaska tax authority (https://tax.alaska.gov/programs/programs/index.aspx?10001) and IRS Topic 409 (https://www.irs.gov/taxtopics/tc409), Rev. Proc. 2025-32 (https://www.irs.gov/pub/irs-drop/rp-25-32.pdf), and NIIT guidance (https://www.irs.gov/individuals/net-investment-income-tax).

How This Calculator Works
Calculation methodology and assumptions
This planning estimate subtracts purchase basis and entered positive basis adjustments from sale proceeds, floors losses at $0, and classifies 13+ entered whole months as long-term because IRS rules require more than one year. General long-term gain is stacked over other federal taxable income through the official 2026 0%/15%/20% brackets; short-term gain is the incremental tax through the official 2026 ordinary brackets for the selected filing status. Incremental NIIT is 3.8% of the lesser-of calculation using entered MAGI and net investment income before and after the gain. State tax is only modeled gain multiplied by an editable flat proxy. It does not prepare Schedule D, Form 8949, Form 8960, or a Alaska return, and it omits losses, selling costs unless netted into proceeds, special federal gain categories, exclusions, AMT, and state-specific computations described below.
Key State Information
Alaska has no broad individual income tax, so this calculator uses a 0% state default. It does not test residency, sourcing, entity-level taxes, or unusual asset-specific taxes. Short- and long-term federal treatment is calculated separately, but the state estimate applies the displayed 0% proxy to either holding period.
How to Use This Capital Gains Tax Calculator
- 1
Enter your basis and sale proceeds
Input what you paid, positive basis adjustments, and what you sold or expect to sell the asset for. This single-sale estimator floors a loss at $0 rather than calculating its tax benefit.
- 2
Select the holding period
Enter how long you held the asset. Federal long-term treatment generally requires more than one year; with the calculator’s whole-month input, 13+ months is treated as long-term. Short-term gains use ordinary rates.
- 3
Review the federal calculation and state estimate
See the modeled federal and Alaska amounts. The federal estimate stacks the gain through 2026 brackets; the state amount is an editable flat-rate proxy and does not apply state brackets, deductions, exclusions, or special capital-gains rules.
Example Calculation
How much tax do you owe on a $50,000 capital gain in Alaska?
You bought stock for $100,000 and sold it for $150,000 after holding for 2 years. In this simplified illustration, the full $50,000 long-term gain is in the 15% federal band, producing $7,500 of regular federal tax before NIIT. Applying the calculator's editable 0% Alaska state-rate proxy adds $0; that proxy is not a state return calculation.
Result: This simplified illustration totals approximately $7,500 (15.0% of gain) using the Alaska proxy. Actual results can cross federal brackets and depend on NIIT, losses, asset type, and state-specific rules.
What Affects Your Results
Holding Period
Long-term (1+ year) vs. short-term changes the federal rate from 0–20% to your ordinary income rate (10–37%). This is the biggest controllable factor.
Income Level
Your taxable income determines whether long-term gains are taxed at 0%, 15%, or 20% federally. Higher income also triggers the 3.8% NIIT surtax.
State Treatment
Alaska can treat gains differently. Eight states currently impose no broad individual income tax, Washington instead has a special long-term capital-gains excise tax, and several states provide deductions, exclusions, credits, or separate rates.
Cost Basis Method
FIFO, LIFO, or specific lot identification can significantly affect your gain amount when selling partial positions. Specific lot ID gives you the most control.
Tips for Alaska Residents
- Federal long-term treatment generally requires holding an asset for more than one year. Count from the day after acquisition through the disposal date; use actual dates rather than assuming a fixed number of days.
- Harvest tax losses to offset gains. If you have losing positions, selling them generates losses that offset gains dollar-for-dollar, reducing your tax bill.
- The 0% long-term capital gains bracket applies to taxable income up to ~$49,450 (single) or ~$98,900 (married filing jointly) in 2026. Strategic Roth conversions or timing of gains can keep you in this bracket.
- Check Alaska's current official treatment of capital gains. State brackets, exclusions, credits, loss rules, and special asset rules can make a flat-rate estimate materially wrong.
- Consider the Net Investment Income Tax (NIIT) — an additional 3.8% surtax on investment income for high earners above $200K single / $250K married.

Our editorial standardsFrequently Asked Questions
What is the capital gains tax rate in Alaska?
There is not one rate that is correct for every Alaska sale. This calculator starts with an editable 0% state proxy, then applies it flat to the modeled gain. Alaska has no broad individual income tax, so this calculator uses a 0% state default. It does not test residency, sourcing, entity-level taxes, or unusual asset-specific taxes.
Does Alaska tax short- and long-term capital gains differently?
Alaska has no broad individual income tax, so this calculator uses a 0% state default. It does not test residency, sourcing, entity-level taxes, or unusual asset-specific taxes.
How is federal capital-gains tax estimated?
For general long-term gain, the calculator stacks the gain above your other taxable income through the 2026 0%, 15%, and 20% brackets. For short-term gain, it computes the increase through the selected filing status’s ordinary brackets. NIIT is a separate incremental lesser-of calculation. Special rates for collectibles, unrecaptured section 1250 gain, and section 1202 stock are not included.
