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 Kansas, 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, 2024, your base period will be from October 1, 2022 through September 30, 2023. It would not include the most recent complete calendar quarter before you filed (October 1, 2023 through December 31, 2023) or the first two-and-a-half months of 2024.
If you have been off work due to a qualifying injury, you may be entitled to use an extended base period that includes earnings from before your injury. In Kansas, the extended base period is the last four complete calendar quarters immediately before you suffered your injury.
