The base period is the length of time used both to determine your eligibility for unemployment benefits and to calculate the amount you will receive.
In Alaska, the base period is the first four of the five complete calendar quarters immediately before you filed for benefits. For example, if you file for benefits on March 15, 2022, your base period will be from October 1, 2020 through September 30, 2021. It would not include the most recent complete calendar quarter before you filed (October 1, 2021 through December 31, 2021) or the first two-and-a-half months of 2022.
If you did not earn enough during the regular base period, you may be able to use an alternate base period that counts more recent earnings. In Alaska, the alternate base period is the last four complete calendar quarters before you file your claim.
If you were incapable of working during most of one of the quarters during the base period, you may be entitled to an extended base period. This means the Alaska Department of Labor and Workforce Development will count earlier work and earnings, from the time when you were still able to work, rather than looking at the quarters when you couldn't work. The base period may be extended up to four calendar quarters before the regular base period.
