HSA vs. FSA vs. HRA - Which Account Does What

Three tax-advantaged healthcare accounts with similar names and very different rules. The 2026 limits, who owns the money, and what happens when you leave your job.

Current as of August 23, 2026 Accounts and taxes

Three accounts, three acronyms, one letter apart. They are not variations on a theme - they differ on the questions that matter most: who owns the money, what happens to it at the end of the year, and whether it follows you when you change jobs.

The short comparison

	HSA	FSA	HRA
Who funds it	You, your employer, or both	You, from pre-tax salary (employer may add)	Employer only
Who owns it	You	Employer holds it, you claim against it	Employer
Requires a specific plan?	Yes - an HDHP	No	Set by employer
Unused money at year end	Rolls over forever	Forfeited, with limited exceptions	Employer decides
Leaves with you?	Yes, always	No	Almost never
Can you invest it?	Usually, above a threshold	No	No
2026 limit	$4,400 self / $8,750 family	$3,400	Employer sets

HSA - the one worth understanding properly

An HSA is the strongest tax-advantaged account in the US code, and it is not close. It is triple tax-advantaged: contributions go in pre-tax, growth is untaxed, and withdrawals for qualified medical expenses are untaxed. Nothing else does all three.

Eligibility. You must be covered by a qualifying high-deductible health plan and generally have no other disqualifying coverage. Enrollment in Medicare ends your ability to contribute, though you can still spend what you have.

2026 figures:

Contribution limit: $4,400 self-only, $8,750 family
Catch-up, age 55 and older: an additional $1,000
HDHP minimum deductible: $1,700 self-only, $3,400 family
HDHP maximum out-of-pocket: $8,500 self-only, $17,000 family

One change worth noting for 2026: bronze and catastrophic plans offered through the ACA marketplace are now treated as HSA-compatible, whether or not they meet the general HDHP definition. That opens HSA eligibility to a group of marketplace enrollees who previously did not have it.

The part most people miss. There is no deadline to reimburse yourself. If you pay a $900 medical bill out of pocket in 2026 and keep the receipt, you can reimburse yourself from the HSA in 2046 - tax-free - while the money compounded untouched in the meantime. That makes an HSA function as a retirement account with better tax treatment, provided you keep records.

Which means: keep every receipt, indefinitely, in a place that is not your employer’s benefits portal.

After age 65, non-medical withdrawals are taxed as ordinary income without the additional penalty that applies earlier - so a well-funded HSA behaves like a traditional retirement account in the worst case and better than one otherwise.

FSA - useful, but use it or lose it

A health FSA is funded from pre-tax salary and is subject to your employer’s plan design.

2026 limits: $3,400 contribution, with a carryover of up to $680 into the following year if your employer offers carryover.

Two quirks that surprise people:

The whole election is available on day one. If you elect $3,400, that full amount is available in January even though you have contributed a fraction of it. If you leave mid-year having spent more than you contributed, you generally do not repay the difference. This is genuinely favorable and largely unknown.

It does not follow you. Leave the job and the FSA usually ends, with a short window to submit claims for expenses incurred while employed.

The forfeiture rule is real but softened: employers may offer either a carryover of up to $680 or a grace period of up to two and a half extra months, but not both. Find out which yours offers before December, not during it.

A dependent care FSA is a separate account with its own limit and its own rules - do not confuse the two during open enrollment.

HRA - entirely your employer’s

An HRA is funded only by the employer. You cannot contribute. The employer decides what it covers, how much it holds, whether unused amounts roll over, and what happens when you leave - which is usually that it ends.

Two variants are worth knowing by name because they change what you can do:

ICHRA - an employer gives you a defined amount to buy your own individual market coverage instead of offering a group plan
QSEHRA - a similar arrangement available to small employers

If you are offered either, it affects your marketplace subsidy eligibility, and that interaction is worth working through carefully before enrolling.

Choosing, in practice

The HSA has the strongest properties of the three. The triple tax advantage, the permanent rollover, and the portability are why, for people with HDHP coverage, it is usually the account a benefits counselor or tax professional looks at first. How much to put where depends on your cash flow, your expected care, and your taxes - which is exactly the question those professionals exist to answer.

You cannot have both a general-purpose FSA and an HSA. They conflict. A limited-purpose FSA - dental and vision only - can coexist with an HSA, and pairing them is a reasonable strategy if your employer offers it.

Without an HDHP, the FSA is the only one of the three you can fund yourself. Its use-it-or-lose-it rule is why conservative estimates are the norm: money forfeited at year end is the common failure mode of this account.

Qualified expenses are broader than most account holders realize. They are broader than most people assume - dental, vision, prescriptions, and a long list of over-the-counter items among them. IRS Publication 502 has the authoritative list, and it is worth ten minutes in November.

The connection to everything else

These accounts change how you pay, not what you owe. A correctly checked bill, a successful appeal, or an approved financial assistance application reduces the underlying number - which is worth considerably more than paying an inflated number with pre-tax dollars.

Fix the bill first. Then pay what remains with the most tax-efficient money you have.
