The core difference is who pays: an HRA (Health Reimbursement Arrangement) is funded entirely by your employer, while an FSA (Flexible Spending Account) is funded primarily by you through payroll deductions. That single distinction drives nearly every other difference between the two, from what happens to unused money to whether you keep the account if you change jobs.
Who Funds the Account
With an FSA, money is withheld from your paycheck before taxes. Your employer can also chip in, but the bulk of the funding comes from you. With an HRA, only your employer contributes. You never see a deduction on your pay stub for an HRA because you’re not putting any of your own money in.
Both accounts share the same basic tax advantage: contributions go in tax-free, and reimbursements for qualified medical expenses come out tax-free. You don’t pay federal income tax or employment taxes on either one. The difference is whose wallet the money originally comes from.
Who Owns the Money
Your employer owns both accounts, technically. But ownership matters far more with an HRA because you can’t directly withdraw HRA funds to pay for expenses. Instead, you pay out of pocket first, then submit a claim for reimbursement. With an FSA, you typically get a debit card linked to the account and can pay directly at the point of sale, which feels more like spending your own money (because it largely is).
This ownership distinction becomes especially important when you leave a job. FSA balances are generally forfeited when your employment ends. You can’t take the account with you. HRA balances are also controlled by your employer, who decides whether any remaining funds follow you or disappear. In practice, most people lose access to both accounts after a job change, though COBRA continuation coverage may temporarily extend access in some cases.
How Much You Can Contribute
FSAs have a strict IRS cap. For 2026, the maximum contribution to a health care FSA is $3,400. That limit applies per employer, per year. If both you and a spouse each have access to an FSA through separate employers, you can each contribute up to the maximum.
HRAs have no IRS-imposed contribution ceiling (with the exception of certain HRA types designed for small employers). Your employer decides how much to put in. Some employers fund HRAs generously; others offer modest amounts. You have no control over the number.
The “Use It or Lose It” Problem
FSAs are governed by the IRS “use or lose” rule: any money left in your account at the end of the plan year is forfeited. To soften this, most employers offer one of two options. The first is a carryover, which lets you roll up to $680 in unused funds into the next year (assuming you re-enroll). The second is a grace period of two and a half months after the plan year ends, giving you extra time to spend down the balance. Employers can offer one or the other, but not both.
HRAs are more flexible on this front. Whether unused funds roll over, and how much, is entirely up to your employer. Many HRA plans do allow year-to-year carryover with no cap, which means your balance can grow over time. Others limit rollovers or eliminate them. Check your plan documents to know what yours allows.
What Each Account Covers
A health care FSA covers a broad, IRS-defined list of qualified medical expenses: doctor visits, prescriptions, dental work, vision care, and many over-the-counter products. The rules are standardized, so you generally know what’s eligible regardless of your employer.
An HRA can cover all of those same expenses, but your employer gets to narrow or customize the list. Some employers design their HRA to reimburse only deductibles and copayments under the company health plan. Others cover a wider range of expenses. One notable difference: HRAs can reimburse certain insurance premiums, including COBRA premiums, long-term care insurance, and Medicare Part A and B premiums. FSAs cannot reimburse any insurance premiums.
When Funds Become Available
With a health care FSA, your full annual election is available on day one of the plan year. If you elect $3,400 for the year, you can spend the entire amount in January even though you’ve only contributed one month’s worth of payroll deductions. This is a significant advantage if you have a large expense early in the year. And if you leave the job before contributing the full amount, your employer can’t come after you for the difference.
HRA funds are available only as your employer credits them. Some employers front-load the full annual amount on January 1, while others add funds monthly or quarterly. The timing depends entirely on the plan design.
Types of FSAs
There are three main FSA varieties:
- Health care FSA: Covers medical, dental, and vision expenses. Full balance available immediately. 2026 limit of $3,400.
- Limited purpose FSA: Covers only dental and vision expenses. This type exists specifically for people who also have a Health Savings Account (HSA), since a regular health care FSA would disqualify them from HSA contributions. Same $3,400 limit.
- Dependent care FSA: Covers childcare or eldercare expenses so you can work. Funds are available only as you contribute them (no front-loading). The annual limit is $5,000 for most households, though some plans allow up to $7,500.
Types of HRAs
HRAs come in several forms, each designed for different employer situations:
- Traditional HRA: Paired with an employer-sponsored group health plan. The employer decides which expenses are reimbursable.
- Individual coverage HRA (ICHRA): Instead of offering group insurance, the employer funds an HRA that employees use to buy their own individual health coverage. There’s no cap on how much employers can contribute, and it’s available to businesses of any size.
- Qualified small employer HRA (QSEHRA): Designed for businesses with fewer than 50 employees that don’t offer group health insurance. Employees use the funds for individual coverage premiums or medical expenses.
- Excepted benefit HRA (EBHRA): A supplement offered alongside a group health plan. It reimburses out-of-pocket medical costs but not insurance premiums.
Using Both at the Same Time
You can have an HRA and an FSA simultaneously if your employer offers both. When that happens, the plan documents spell out which account pays first. The default rule is that expenses are reimbursed from the HRA first, then from the FSA once the HRA balance runs out. However, many employers flip this order so the FSA pays first, which reduces the chance you’ll forfeit unused FSA dollars at year-end.
Some employers design the two accounts to cover different categories of expenses entirely. For example, your FSA might cover only dental and vision costs, while your HRA handles deductibles and copayments under the medical plan. This approach avoids confusion about which account to tap and helps both balances get used efficiently.
Which One Works Better for You
If your employer offers only one of these accounts, the decision is made for you. But if you have a choice, the right pick depends on your situation. An HRA is essentially free money from your employer, so it’s almost always worth using if available. An FSA requires you to predict your annual medical spending in advance and commit your own pretax dollars, but it gives you more control over the amount and immediate access to the full balance.
People with predictable annual expenses (ongoing prescriptions, planned dental work, regular therapy visits) tend to get the most value from an FSA because they can estimate spending accurately and avoid forfeiting funds. People whose employers offer generous HRA contributions benefit from letting that money accumulate year over year, especially if their plan allows rollovers. If you have access to both, using them together with a coordinated payment order gives you the most coverage with the least waste.
