How much is the Alaska corporation biennial report?

$100, filed every two years. It is filed as the Biennial Report (filed online through the DCBPL Division of Corporations; $100 for a domestic corporation, $200 for a foreign corporation). Averaged out that is $50 a year.

Why does Alaska only ask for a report every two years?

Alaska is one of 7 states on a biennial corporate cycle; 41 states require an annual report and 2 require none. The filing is the same, it simply comes around half as often, so compare it against other states on an annualized basis rather than per filing.

An Alaska corporation files the Biennial Report every two years and pays $100, which averages $50 a year. Due by January 2 of the applicable filing year, every two years, keyed to the year of formation (even-year formations report in even years; odd-year formations in odd years); the filing period opens about three months before the due date. A one-time initial report (no charge) is also required after incorporation.

Alaska is one of 7 states on a biennial corporate reporting cycle — which works out to $50 a year once averaged, the number to use when comparing against annual-filing states. Nationally, 41 states require an annual corporate report, 7 require one every two years, and 2 require none.

What the filings cost over five years

State filing charges only — incorporation plus five years of reporting, annualized. Because this state reports every two years, the yearly figure is the fee halved; a biennial filer actually writes two or three cheques over five years, not five. Corporate income tax and franchise tax are excluded, because both depend on income or net worth.

Period	State filing charges
Incorporation	$250
Each year after (report, annualized)	$50
Five-year equivalent (annualized)	$500

That ranks Alaska 38th cheapest of 49 states on five-year corporate filing charges.

Alaska corporation vs Alaska LLC

State filing charges only. Corporate income tax and franchise tax are excluded because both depend on income or net worth, so no flat figure exists for either entity.

	Corporation	LLC
Formation filing fee	$250	$250
Report cadence	Every two years	Every two years
Report fee	$100	$100

Both entities cost $250 to file in Alaska, so the filing fee is not a reason to pick one over the other.

State taxes a Alaska corporation pays

Corporate income tax

Applies	Yes
Rate	Graduated corporation net income tax from 0% to 9.4%, in increments of $24,000/$25,000 of taxable income: 0% on taxable income of $25,000 and below, up to 9.4% on taxable income of $222,000 and over (based on federal taxable income with Alaska adjustments). Filed on Form 6000.

Alaska publishes no corporate franchise or gross-receipts tax.

What these totals leave out: the filing-charge figures on this page are what you pay the business filing office. They exclude corporate income tax and any franchise or gross-receipts tax, because both depend on income, net worth or receipts. The section above sets out what Alaskalevies — or that it levies neither. Where a state's franchise tax carries a flat minimum, that minimum is an unavoidable annual cost these totals do not include, and over five years it can be the larger number.

Where these numbers come from

This page covers the recurring report a for-profit corporation files with Alaska. Every figure was checked against Alaska's own published sources on July 29, 2026— the state business filing agency's fee schedule, the governing statute, and where a state tax applies, the state Department of Revenue. Commercial formation-service pages were used as leads only and are never cited. Anything the review could not confirm from an official source is left blank on this page rather than filled with an estimate.

Corporate income tax and franchise tax are quoted as the state publishes them, as rate schedules and thresholds, and are excluded from every dollar total here. They depend on income or net worth, so there is no flat figure that would be true for every corporation.
