You can rollover up to $680 of unused money in your Health Care or Limited Purpose FSA to next year—even if you don’t sign up again.
If you elect the Advantage HDHP and HSA for a future year, try to use all your Health Care FSA money before the year ends. That’s because you can’t put money into an HSA if you still have leftover Health Care FSA funds.
*Dependent Care FSAs are not eligible for the roll over feature.
