The acronyms look similar, but ownership, eligibility, rollover rules and funding are not interchangeable. The Internal Revenue Service groups HSAs, health FSAs and HRAs among tax-favored health arrangements, while HealthCare.gov also distinguishes them from the underlying health insurance plan itself.
HSA vs. FSA vs. HRA at a glance
| Feature | HSA | Health FSA | HRA |
|---|---|---|---|
| Who establishes it? | Individual account, often connected with employer benefits | Employer | Employer |
| Who can contribute? | Eligible individual, employer or others, subject to tax rules | Employee salary reduction and/or employer | Employer only |
| Ownership | Generally belongs to the individual | Employer plan arrangement | Employer plan arrangement |
| Rollover | Unused balance generally remains in the HSA | Plan may offer limited carryover or a grace period under applicable rules; otherwise unused funds can be forfeited | Depends on the employer’s HRA design |
| Health-plan requirement | Specific HSA eligibility rules apply, generally including qualifying HDHP coverage | Employer plan rules apply | Depends on the type of HRA |
How an HSA works
A Health Savings Account is a tax-favored account for an eligible individual. IRS rules generally require qualifying high-deductible health plan coverage and restrict certain other health coverage. Contributions can come from the individual, employer or another person, subject to annual limits and eligibility rules. Qualified medical distributions can be tax free, and unused HSA money generally carries forward from year to year.
Because the account is generally owned by the individual, changing employers does not normally mean forfeiting the HSA balance. Annual contribution limits and qualifying-plan thresholds can change, so use current IRS guidance rather than an old article’s dollar figures.
How a health FSA works
A health Flexible Spending Arrangement is an employer-established benefit. Employees commonly elect a salary reduction, and the employer may also contribute. Qualified reimbursements can receive favorable tax treatment.
Health FSAs are subject to plan-year rules. Employers may choose certain carryover or grace-period features when permitted by tax rules, but employees should not assume that every FSA balance automatically rolls over. Review the plan document and year-end deadlines.
How an HRA works
A Health Reimbursement Arrangement is funded solely by the employer. The employee does not contribute through voluntary salary reduction. The employer sets the reimbursement design within applicable federal rules, including the maximum amount and which eligible expenses can be reimbursed.
There are multiple HRA structures. Some are integrated with traditional group health coverage, while others—such as individual coverage HRAs—have separate coverage conditions. HealthCare.gov notes that some HRA types require employees and eligible household members to have other qualifying health coverage.
Qualified medical expenses matter
Tax-favored treatment depends on using the arrangement according to its rules. IRS Section 213 concepts generally focus on expenses for diagnosis, cure, mitigation, treatment or prevention of disease and certain other medical care. But an expense that is medically related in everyday language is not automatically eligible. Check the current IRS publication and the employer plan.
Can you have more than one account?
Sometimes, but coordination rules matter. Certain general-purpose health FSAs or HRAs can make a person ineligible to contribute to an HSA, while limited-purpose or post-deductible arrangements may be structured differently. This is an area where benefit-plan design and IRS rules should be checked before contributing.
Questions to ask during benefits enrollment
- Am I actually eligible to contribute to an HSA this year?
- What is the employer contribution, if any?
- Does the FSA offer a carryover or grace period, and what are the deadlines?
- Which expenses can the HRA reimburse?
- Will another FSA or HRA affect HSA eligibility?
- What happens to unused balances if I leave the employer?
- What are the current annual federal limits?
Frequently asked questions
Is an HSA the same as health insurance?
No. An HSA is a tax-favored account. It does not replace the health plan, and HSA eligibility is tied to specific health-coverage rules.
Does an FSA balance always roll over?
No. Employer plan design and federal rules determine whether a limited carryover or grace period is available.
Can employees put their own money into an HRA?
No. IRS guidance states that an HRA must be funded solely by the employer.
Can HSA funds stay with me after I change jobs?
Generally yes. The HSA is typically owned by the individual, although future contributions still require HSA eligibility.
