Corporate Income Tax



Alaska levies a corporate income tax on Alaska taxable income which is based on federal taxable income with certain Alaska adjustments.

Multistate corporations apportion income on a water's edge basis using the standard apportionment formula of property, payroll and sales. Oil and gas corporations use a modified apportionment formula applied to worldwide income.

Tax rates are graduated from 0% to 9.4% in increments of either $24,000 or $25,000 of taxable income. The 0% rate applies to taxable income of $25,000 and below, while the 9.4% rate applies to taxable income of $222,000 and over.

Payment of the Alaska tax must be made on or before the 15th day of the fourth month after the close of the tax year. The payment due date cannot be extended. When an estimated payment is $100,000 or greater, or a payment with a return is $150,000 or greater, payment must be made online (Revenue Online) or by wire transfer. Tax returns are due 30 days after the Federal return due date. If the Federal return is on extension the Alaska return is automatically on extension.
