HSA vs FSA vs HRA: Which Tax-Free Health Account Do You Actually Have?

The One-Paragraph Answer

An HSA (Health Savings Account) is yours — it requires a high-deductible health plan, rolls over every year, and you keep it if you change jobs. An FSA (Flexible Spending Account) comes only through an employer, and most plans make you spend the money within the year or lose it. An HRA (Health Reimbursement Arrangement) is funded only by your employer — you do not contribute at all. All three let you pay for medical costs with pre-tax money. They differ in who funds them, what happens to leftover money, and who owns the account when you walk away.

HSA: The Account You Own

A Health Savings Account is the most powerful of the three, and it is available only if you are enrolled in a high-deductible health plan (HDHP). Its famous triple tax advantage works like this:

  • Tax-free going in. Contributions are pre-tax through payroll — which also skips Social Security and Medicare taxes — or deductible on your tax return if you contribute directly.
  • Tax-free growth. Interest, dividends, and investment gains inside the account are never taxed.
  • Tax-free coming out. Withdrawals for qualified medical expenses are tax-free at any age.

No other account offers all three at once. The money rolls over year after year with no deadline, it is fully portable when you change jobs, and most providers let you invest the balance once you keep a cash cushion — so it can grow like a retirement account. Many people pay medical bills out of pocket, save the receipts, and let the HSA compound for decades; there is no time limit on reimbursing yourself tax-free later.

The 2026 Numbers You Need to Know

The IRS adjusts these figures for inflation every year. For 2026:

  • HSA contribution limit: $4,400 for self-only coverage, $8,750 for family coverage — your contributions plus any employer contributions combined. If you are 55 or older, you can add a $1,000 catch-up on top.
  • HDHP qualifying test: a plan counts as an HDHP only if its deductible is at least $1,700 (self-only) or $3,400 (family) and its out-of-pocket maximum does not exceed $8,500 (self-only) or $17,000 (family). A plan marketed as "high deductible" does not automatically qualify — check the actual numbers.
  • FSA contribution limit: $3,400 per employee, per employer plan. If your plan offers a carryover, up to $680 of unused money can roll to next year.

FSA: The Use-It-or-Lose-It Account

A Flexible Spending Account is available only through an employer that offers a group health plan — no high-deductible plan required. Contributions come out of your paycheck before taxes, which lowers your taxable income.

The catch is the deadline: unused money generally does not roll over. Employers can offer either a carryover (up to $680 for 2026) or a grace period into the next year, but rarely more than that. Anything left beyond the plan's rules disappears. So estimate carefully during open enrollment: set aside roughly what you will actually spend on copays, prescriptions, dental work, vision, and other eligible costs — not more.

One more difference from an HSA: an FSA is tied to your job. When you leave, the account generally stays behind with the employer.

HRA: The Account Your Employer Pays For

A Health Reimbursement Arrangement is entirely employer-funded — only the employer puts money in; employees contribute nothing. The employer sets the rules: how much is available, which expenses qualify, and whether unused funds roll over to the next year.

Because every employer designs its HRA differently, the details vary widely from company to company. What you get from an HRA is essentially a tax-free reimbursement pot for medical costs — generous while you are employed, but you do not own it the way you own an HSA, and the money generally stays behind if you leave.

The Side-by-Side Comparison

  • Who contributes: HSA — you (your employer may add too); FSA — you, through payroll; HRA — employer only.
  • Needs a high-deductible plan: HSA — yes; FSA — no; HRA — no.
  • What happens to leftover money: HSA — rolls over fully, forever; FSA — up to $680 carryover or a short grace period, if your plan allows; HRA — depends entirely on your employer.
  • Portable when you change jobs: HSA — yes; FSA — no, usually; HRA — no.
  • Tax treatment: HSA — triple tax advantage; FSA — pre-tax contributions and tax-free withdrawals for eligible expenses; HRA — employer contributions are tax-free to you, and reimbursements are tax-free.

The Rules That Trip People Up

  • A general FSA and an HSA cannot coexist. If you are covered by a standard FSA that reimburses all medical expenses, you cannot contribute to an HSA. The workaround is a limited-purpose FSA (dental and vision only), which pairs fine with an HSA.
  • Medicare ends HSA contributions. The month you enroll in any part of Medicare — including Part A — your HSA contribution eligibility stops. You can still spend down an existing balance, but no new money goes in.
  • Your spouse's plan can disqualify you. If a spouse's non-HDHP plan covers you, you lose HSA contribution eligibility.
  • HSA withdrawals have two faces. Before age 65, non-medical withdrawals face income tax plus a 20% penalty. After 65, they are simply taxed as ordinary income with no penalty — effectively a traditional retirement account at that point.
  • Two states tax HSAs. California and New Jersey do not follow the federal HSA tax exclusion, so residents there owe state income tax on contributions and earnings (the federal benefits still apply).

The Bottom Line

Before open enrollment, figure out which account you actually have with three questions: Is it tied to a high-deductible plan or offered by my employer? Does leftover money roll over? And who puts the money in? Then act accordingly: max out an HSA if you can — it is the only one that is truly yours — spend down the FSA before the deadline, and treat the HRA as the employer's bonus on top. The account only saves you money if you fund it on purpose, so decide your number before enrollment closes. And if the deductible side of your plan is still fuzzy, the deductibles article on this blog explains how those work in detail.
