How Alaska Income Tax Works
Alaska has no state income tax on wages. Your only income tax obligation is federal — there's no Alaska return required for wage income, and your taxable income at the state level is effectively zero.
For most Alaska residents, the 2026 federal standard deduction ($16,100 single, $32,200 married filing jointly) is applied first; only income above that gets taxed at federal rates of 10% to 37%. Use the calculator above to see how your specific salary maps to brackets.
Residents receive an annual Permanent Fund Dividend (about $1,300 in 2024) — a payout funded by oil revenue.
Oil and gas, fishing, and tourism dominate Alaska's economy.
Frequently Asked Questions
What is the Alaska state income tax rate for 2026?
Alaska has no state income tax on wages — the rate is 0% across all income levels. The only federal income tax applies, with brackets ranging from 10% to 37% depending on your taxable income.
How much income tax will I pay in Alaska on a $100,000 salary?
For a single filer earning $100,000 in Alaska in 2026, expect approximately $13,170 in federal income tax — for a total income tax of about $13,170, an effective rate of 13.2%. This excludes FICA (Social Security and Medicare), which adds roughly 7.65% on top.
What's the difference between effective and marginal tax rate?
Your marginal rate is the rate applied to your last dollar of taxable income — the bracket your top dollar lands in. Your effective rate is your total income tax divided by your total income — the average rate across everything you earned. Effective is always lower than marginal because lower brackets cover the first portions of your income at lower rates.
Does Alaska tax retirement income, Social Security, or capital gains?
Federal rules: long-term capital gains use preferential rates (0%, 15%, 20%) — see our Capital Gains Tax Calculator. Social Security is taxable federally if your combined income exceeds certain thresholds. Alaska has no state income tax, so retirement income, Social Security, and capital gains are not taxed at the state level either.
How is this Alaska income tax estimate calculated?
We apply the 2026 federal IRS tax tables (10%–37% across seven brackets) to your taxable income (gross income minus the standard deduction). The calculator handles wages, self-employment income (with SE tax and the deductible half), and other income; you can also switch to itemized deductions. Tax credits, AMT, and preferential capital gains rates are not modeled — this is an estimate of ordinary income tax only.
