Why A is correct
The classic distinction: FSAs generally follow a use-it-or-lose-it rule — money not spent on eligible expenses by the deadline is forfeited (subject to limited carryover or grace-period options). HSAs are owned by the individual and their balance rolls over year after year with no forfeiture. Both are tax-advantaged, but ownership and portability differ fundamentally.
Why the other options are wrong
- B) Both FSA and HSA contributions enjoy tax advantages; the difference is not between taxed and untaxed status.
- C) Ownership is the reverse: the HSA belongs to the individual and is portable, while the FSA is typically employer-sponsored and lost when the job ends.
- D) HSAs can be invested once balances grow (some plans), while FSAs are spending accounts — but this is not the defining difference tested.
Memory hook
FSA = use it or lose it. HSA = save it forever. The 'H' stands for 'Hang on to it.'
