Which is true of a flexible spending account but not a health savings account

Answer 1

One true statement about a flexible spending account (FSA) that does not apply to a health savings account (HSA) is that FSAs are subject to a "use it or lose it" rule. This means that any unused funds in an FSA at the end of the plan year are generally forfeited, whereas funds in an HSA typically roll over from year to year and accumulate over time.
