Commuter Benefit Plans are a monthly benefit and unused balances will automatically roll from month to month. There is no “use-it-or-lose-it” with a CBP at the end of the year. Additionally, there is no requirement to re-enroll each year. Elections will automatically roll until you request a change. If you are submitting a claim for eligible van pool or parking expenses, reimbursements must be requested within 180 days of incurring the expense.
