Quarterly Estimated Tax Calculator — Alaska (2026)
If you earn income in Alaska without withholding — freelancing, contracting, rentals, dividends — the IRS expects payment four times a year, not once. This calculator turns your expected 2026 net profit into a per-quarter number covering self-employment tax, federal income tax and no state tax, since Alaska has none. Alaska does not levy a personal state income tax, so the only mandatory withholding on your earnings is federal income tax plus FICA (Social Security and Medicare).

2026 due dates and safe harbor
Federal estimated payments are due April 15, June 15, September 15 of 2026 and January 15 of 2027. You avoid penalties by paying either 90% of the current year's liability or 100% of last year's (110% if prior-year AGI exceeded $150,000) — the safe-harbor rule.
There is no Alaska estimated payment to make — the state does not tax personal income, so you only file federally.
Underpayment penalties
The IRS charges interest-style penalties per quarter you fall short, currently around 7–8% annualized. Paying late in the year does not fix an early-quarter shortfall unless you use the annualized income method on Form 2210.
Irregular income is common in oil work around Anchorage: if Q1 is slow and Q4 is huge, the annualized method usually beats four equal payments.
Paying as a Alaska taxpayer
Pay federally through IRS Direct Pay or EFTPS — no state portal is needed.
Alaska has no state income tax AND no state sales tax — but most boroughs/cities levy a local sales tax up to 7.5%.
Local and payroll taxes Alaska adds on top
Alaska adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
Alaska has no state income tax AND no state sales tax — but most boroughs/cities levy a local sales tax up to 7.5%.
Nobody withholds these for you when you are self-employed in Alaska. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from Alaska
Alaska has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Anchorage resident spending part of the year at a client site in Washington may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Alaska tax bill
Alaska charges no general sales tax, homeowners pay an average effective property tax of 1.07% of market value, and the minimum wage in force during 2026 is $14.00 an hour.
No statewide sales tax; some boroughs levy up to 7.5%.
Income tax is only one part of a state's take. Alaska recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. With no state income tax, Social Security, pensions, 401(k) and IRA withdrawals are all free of state tax here.
Alaska vs Washington on the same salary
On a $90,000 salary, a single filer keeps about $72,145 a year in Alaska against roughly $72,145 in Washington — a difference of $0, or $0 a month.
Effective combined rates are 19.8% in Alaska and 19.8% in Washington. Set that gap against living costs: index 127 here versus 116 there, with property tax at 1.07% and 0.94% respectively.
