Which employer-sponsored benefit allows employees an opportunity to contribute funds that must be used within the calendar year?

A flexible spending account (FSA) lets employees set aside money from their paychecks for eligible expenses, usually during a plan year. Under the traditional “use-it-or-lose-it” rule, unused funds generally must be spent by the deadline rather than carried over indefinitely. An HSA can allow balances to roll over, while pensions and 401(k)s are retirement benefits.
