An FSA (Flexible Spending Account) and an HSA (Health Savings Account) both allow you to use pre-tax dollars for eligible medical expenses. However, FSAs are generally "use-it-or-lose-it" accounts owned by your employer, whereas HSAs are individually-owned, roll over year-to-year, and require you to be enrolled in a High-Deductible Health Plan (HDHP). [1, 2, 3]
Key Differences at a Glance
| Feature [1, 2, 4, 5, 6, 7] | Health Savings Account (HSA) | Flexible Spending Account (FSA) |
| --- | --- | --- |
| Health Plan Required | Must be enrolled in a high-deductible health plan (HDHP). | Any health plan; often paired with traditional insurance. |
| Account Ownership | You own the account; it goes with you if you change jobs or retire. | The employer owns the account. If you leave, you lose any unspent funds. |
| Fund Rollover | Unused funds roll over indefinitely and can even be invested. | Usually "use-it-or-lose-it." Unspent funds may be forfeited back to your employer (some plans allow a small carryover or a grace period). |
| Funding Access | You can only spend what you have already contributed. | Your total annual contribution is available on day one of the plan year. |
Contribution Limits
The maximum amounts you can put into these accounts are subject to IRS annual adjustments:
• HSA (2026): Up to $\$4,400$ for individuals and $\$8,750$ for families. (If you are 55 or older, you can contribute an extra $\$1,000$ catch-up contribution).
• FSA: Set by the IRS, but employers may set a lower limit. [1, 4, 5, 10]
Can you have both?
You cannot contribute to a traditional Healthcare FSA and an HSA in the same year. However, if you have an HSA, you can typically pair it with a Limited Purpose FSA (LEX HCFSA), which is restricted solely to dental and vision expenses. [4, 11]
Eligible Expenses
Funds in both accounts can be used for out-of-pocket costs such as deductibles, co-pays, prescriptions, and certain over-the-counter medical products. You can view a complete directory of qualifying items using the FSA Store Eligibility List
