Key Takeaways

  • 1HSA requires high-deductible health plan; FSA works with any plan.
  • 2HSA rolls over forever; FSA is use-it-or-lose-it (some rollover allowed).
  • 3HSA is triple tax-advantaged; FSA is pre-tax only.
  • 4Max HSA first if eligible — it is the superior account.

Both FSAs and HSAs let you pay medical expenses with pre-tax dollars — but HSAs are dramatically better if you qualify.

Read HSA triple tax advantage.

FSA Limitations

2025 limit ~$3,200. Lose unused funds (or roll $640). Not portable between employers. Good for predictable medical costs.
