HSA vs FSA
Content context: plan year 2026
In short
An HSA belongs to you and unused funds roll over. A health FSA is an employer benefit, with use-it-or-lose-it rules and possible limited carryover or a grace period. New HSA contributions require compatible coverage and personal eligibility. From January 1, 2026, individual-market bronze and catastrophic plans available through an Exchange qualify even outside ordinary HDHP limits, including when the same plan is bought off-exchange.

When HSA wins
Consider an HSA if your coverage qualifies and you meet the personal contribution rules. Medicare, disqualifying other coverage (often including a general-purpose health FSA), and tax-dependent status can prevent new contributions. Unused funds remain yours even if you later lose contribution eligibility.
When FSA wins
Consider an employer health FSA for predictable eligible expenses when that benefit is available. Check its deadline, carryover or grace period before choosing an amount. A general-purpose health FSA can disqualify you from HSA contributions; limited-purpose arrangements may differ.
The bottom line
First check coverage and personal eligibility, then compare portability, employer contributions and how much you can use. An HSA rolls over; a health FSA has spending deadlines. Neither account makes an otherwise expensive health plan the better choice.
