What Is the Base Period?
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 New York, 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 July 10, 2015, your base period will be from April 1, 2014 through March 31, 2015. It would not include the most recent complete calendar quarter before you filed (April 1, 2015 through June 30, 2015) or the first ten days of July 2015.
If you did not earn enough to qualify for benefits during the regular base period, you may be able to use an alternate base period that counts more recent earnings. In New York, the alternate base period is the last four complete calendar quarters before you file for benefits.
