HSA vs FSA vs HRA
Three accounts, three very different tools. The HSA is the most powerful but requires HDHP coverage. The FSA is widely available but use-it-or-lose-it. The HRA is employer-controlled. This comparison shows the trade-offs and the right pick for your situation.
TL;DR
If you qualify for an HSA (have HDHP coverage), pick it — it's the best account in the tax code. If you don't qualify but your employer offers an FSA, use it for known medical expenses. HRA is employer-funded; you don't choose it but you should know how it works if your employer offers one.

Which one should you pick?
HSA — if you Have HDHP coverage. Triple tax advantage + portability + growth makes this the best medical account in the code.
FSA — if you Don't qualify for HSA but have predictable medical expenses your employer-offered FSA can cover. Estimate carefully — anything unused at year-end (over the carryover) is lost.
HRA — if you Your employer offers one. Take whatever they give you and use it for qualifying medical expenses.
Both HSA + FSA (Limited Purpose) — if you Have an HSA but also want to use FSA for dental and vision (a 'Limited-Purpose FSA' is allowed alongside an HSA).
Common questions
Can I have both an HSA and an FSA?+
Not a traditional FSA — that would disqualify you from HSA contributions. But you CAN have an HSA alongside a Limited-Purpose FSA (dental and vision only) or a Dependent Care FSA (for childcare).
What happens to my HSA if I change jobs?+
It stays yours. The HSA is fully portable — you keep the account and the balance regardless of where you work. This is one of its biggest advantages over FSA and HRA.
What's the 'stealth retirement account' strategy with an HSA?+
Max your HSA every year. Pay current medical expenses out of pocket (save the receipts). Let the HSA grow invested for decades. After 65, withdraw tax-free for accumulated medical receipts OR for any purpose (taxed like Traditional IRA). Decades of tax-free growth — extremely powerful.
Is the FSA carryover automatic?+
No — the carryover (up to $640 in 2025) only applies if your employer's FSA plan includes it. Some plans offer a 2.5-month grace period instead. Check your plan documents.
