Year-End Plan Options
Grace Period/Run-out Period/Rollover Option:
Run-out Period: This is an additional period of time during which you are allowed to file claims for expenses incurred during your previous Plan Year.
Rollover Option (aka Carryover Option): If your plan has a rollover option, at the end of the Plan Year unused funds (up to $660) will rollover into your FSA account for the next Plan Year.
Grace Period: This is the time between the last day of the Plan Year and the Final Date to Incur Claims (final date to use your FSA funds). The grace period gives you a little extra time to use the money from your FSA.
