How long can Health Care FSA funds be carried over? Are multiple year Carryovers permissible?

Funds may be carried over indefinitely if you remain enrolled in the Health Care FSA plan. If you do not re-enroll for the next plan year, you are able to carry over up to $550 for one year, but if you do not re-enroll for two consecutive years, you will forfeit any remaining Carryover funds.
