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

Answer 1

One key difference between a health savings account (HSA) and a flexible spending account (FSA) is that the funds in an HSA roll over from year to year and accumulate over time, whereas funds in an FSA typically do not roll over and are forfeited if not used by the end of the plan year. This means that with an HSA, you can save and invest your funds for future medical expenses, while with an FSA, you need to use the funds within a specific timeframe.
