HSA vs FSA vs HRA: What's the difference?

HSAs, FSAs, and HRAs are all tax-advantaged ways to pay for medical expenses, but they work very differently. Understanding who owns the account, how the money rolls over, and what you can use it for can save you real money.

Quick comparison: HSA vs FSA vs HRA

Health Savings Accounts (HSAs)

An HSA is available only if you are enrolled in an HSA-qualified high-deductible health plan (HDHP). HSAs offer a "triple tax advantage": contributions are tax-deductible (or pre-tax through payroll), growth is tax-free, and withdrawals for qualified medical expenses are tax-free.

• Funds roll over year to year with no expiration
• The account stays with you even if you change jobs
• Once your balance is high enough, many providers allow you to invest

If you are new to HSAs, start with what an HSA is and how it works.

Flexible Spending Accounts (FSAs)

An FSA is offered by employers and funded through pre-tax payroll deductions. It is best for predictable, short-term medical expenses.

• Money generally must be used within the plan year
• Plans may allow a carryover of up to $680 (or a grace period depending on plan rules in 2026
• The account is usually forfeited if you leave your job

Health Reimbursement Arrangements (HRAs)

An HRA is funded entirely by your employer. Because it is not funded with your own salary, reimbursements are generally tax-free to you.

Common HRA types

• ICHRA: Can reimburse individual health insurance premiums and other eligible medical expenses (depending on the plan design)
• QSEHRA: Available to small businesses (generally under 50 full-time employees)

Unlike HSAs and FSAs, some HRAs can be used to reimburse insurance premiums, which can be a unique advantage.

Important rules to know

• No double dipping: You cannot use more than one account (for example, an HRA and an HSA) to reimburse the same expense.
• Compatibility matters: Certain HRAs and general-purpose FSAs can disqualify you from contributing to an HSA.
• Rollover is not the same as ownership: Even when money can roll over, the account may still not be portable if you leave your employer.

Which account is best?

It's up to you to decide what's best for you and your family, but in general:

• Choose an HSA if you want long-term savings and potential investment growth
• Choose an FSA if you have predictable, near-term medical costs
• Choose an HRA if your employer offers generous reimbursements

In some cases, people combine accounts (such as an HSA and a limited purpose FSA) to maximize tax savings.
