HSA vs FSA vs HRA: Your Health Accounts, Explained in Plain English

Reviewed by the Evolve Health clinical team · 2026-10-01 · 4 min read

Open enrollment packets love alphabet soup: HSA, FSA, LPFSA, DCFSA, HRA. They all hold pre-tax money for health costs, but the rules underneath are wildly different — and picking wrong can cost you real money.

Here's each account, explained the way we'd explain it to a patient in the exam room.

HSA — Health Savings Account

Yours. You own it, it follows you from job to job, and unused money rolls over forever — there's no expiration date.

• Requires enrollment in a qualifying high-deductible health plan (HDHP)
• 2026 limits: $4,400 self-only / $8,750 family, plus $1,000 catch-up at 55+
• Triple tax advantage: deductible contributions, tax-free growth, tax-free withdrawals for medical expenses
• You can invest the balance for long-term growth
• After 65, it works like a retirement account for non-medical withdrawals too

The HSA is the most flexible of the bunch — if your health plan qualifies you for one. (We wrote a full guide to using your HSA wisely.)

Health FSA — Flexible Spending Account

Your employer's. The company owns the account; you're just allowed to use it while you work there.

• No HDHP required — available with most traditional health plans
• 2026 limit: $3,400 in salary reductions
• The big catch is "use it or lose it" — with one important exception: if your employer's plan allows it, you can carry over up to $680 into next year. Some plans instead offer a short grace period to spend leftover funds. And some plans offer neither — so check your plan documents, because this part is employer's choice, not a guarantee.
• Leave your job, and you generally leave the FSA money behind (COBRA continuation is the rare exception)

An FSA is great for expenses you can predict — braces, glasses, prescriptions you refill every month. It's a poor place to park money "just in case."

Limited-purpose FSA — the HSA's companion

This one exists for a single clever reason: it covers only dental and vision expenses, which means the IRS lets you hold it alongside an HSA.

• Same use-it-or-lose-it structure as a regular health FSA
• Use it for cleanings, fillings, crowns, glasses, contacts, LASIK
• Keep your HSA for everything medical, and let the HSA keep growing

If you have an HSA and expect dental or vision costs, this combo is worth asking your benefits team about.

Dependent care FSA — not a medical account at all

Despite the similar name, this account has nothing to do with medical bills. It pays for child or dependent day care — babysitters, daycare, after-school programs, elder day care — so you (and your spouse, if married) can work.

• Separate contribution limits and completely separate rules from health FSAs
• Cannot be used for doctor visits, prescriptions, or any medical expense
• Also use-it-or-lose-it

The name causes endless confusion. Just remember: dependent care = daycare, not healthcare.

HRA — Health Reimbursement Arrangement

Employer-funded only. Your employer puts the money in; you can't contribute a dime.

• The employer designs the rules: what's covered, how much, whether unused amounts roll over
• Reimbursements for qualified medical expenses are tax-free to you
• Can sometimes be paired with other coverage — it depends on the HRA type your employer chose
• Nothing to report on your tax return

Think of it as your employer handing you a health-spending allowance with their own strings attached.

Quick comparison

• Who owns it: HSA — you. Health FSA — your employer. Limited-purpose FSA — your employer. Dependent care FSA — your employer. HRA — your employer.
• Unused money: HSA — rolls over forever. Health FSA — mostly use-it-or-lose-it (up to $680 carryover if your plan allows). HRA — employer's choice.
• Needs an HDHP: HSA — yes. All others — no.
• You can invest it: HSA — yes. The rest — no.
• Follows you to a new job: HSA — yes. The rest — generally no.

Can you have more than one?

• HSA + regular health FSA: generally no — the IRS won't let you double up.
• HSA + limited-purpose FSA: yes — this is the intended pairing.
• HSA + dependent care FSA: yes — they're entirely separate (daycare vs. healthcare).
• HRA + anything: depends on the HRA type — ask your benefits team.

Which is best?

There's no universal winner — it depends on your health plan, your expected expenses, and whether you'll actually spend FSA money before the deadline. As a rule of thumb: if you have an HDHP and can afford to, maxing the HSA beats funding an FSA, because the HSA money is yours forever and can grow.
