Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) are both designed to help individuals pay for eligible medical expenses with tax advantages, but they differ significantly in structure, eligibility, and usage. Understanding these differences can help you make informed decisions about which account suits your healthcare needs and financial goals.
Origins and Purpose
FSAs were introduced in the 1970s as an employer benefit to let employees set aside pre-tax dollars for medical expenses. HSAs, introduced in 2003 alongside the rise of high-deductible health plans (HDHPs), aim to provide individuals with more control and flexibility in saving for healthcare costs.
Ownership and Eligibility
HSAs are individually owned, meaning the account belongs to you even if you change jobs or insurance plans. To be eligible, you must be enrolled in an IRS-qualified HDHP and not be covered by other disqualifying health coverage, including Medicare.
FSAs are employer-established accounts; only employees of companies offering FSAs can participate. Contributions are deducted from your paycheck before taxes. Eligibility depends on your employer offering the plan, and self-employed individuals cannot establish FSAs.
Contribution Limits and Funding
For 2025, the IRS sets the HSA contribution limits at $4,150 for individual coverage and $8,300 for family coverage, with an additional $1,000 catch-up contribution allowed for those 55 and older. Contributions can be made by you, your employer, or both.
FSAs have a lower annual contribution limit—$3,200 in 2025—established by the IRS, with contributions typically through payroll deductions. Employers may also contribute.
Fund Usage and Taxes
HSA funds can be used tax-free for qualified medical expenses defined by the IRS, including prescriptions, doctor visits, and certain insurance premiums. Unused funds roll over indefinitely and can be invested for potential growth, offering triple tax advantages: tax-deductible contributions, tax-free earnings, and tax-free withdrawals for qualified expenses.
FSA funds must generally be used by the end of the plan year or during a short grace period (usually 2.5 months), or the unused amount is forfeited—known as the “use-it-or-lose-it” rule. FSAs do not allow investment of funds and have no rollover benefits, except some employers may offer a limited rollover of up to $610.
Portability and Flexibility
HSAs are fully portable; you keep the account and funds regardless of job changes or retirement. They can be used for qualifying expenses for yourself, your spouse, and dependents.
FSAs are not portable. If you leave your employer, any unused money in your FSA is forfeited unless you elect COBRA continuation coverage, which allows you to continue using the funds but requires paying premiums.
Common Use Cases
- HSAs are ideal for individuals with HDHPs who want long-term savings for medical expenses and the ability to invest and carry over funds.
- FSAs fit employees who expect regular medical expenses within the year and want to use pre-tax money quickly.
Tips for Maximizing Benefits
- Maximize your HSA contributions if you qualify to build a health savings nest egg that can also supplement retirement savings.
- Estimate your medical expenses carefully before contributing to an FSA to avoid forfeiting unused funds.
- If available, consider combining both accounts strategically to cover immediate and future medical costs.
Common Misconceptions
- You can have both an HSA and an FSA only under specific circumstances, typically if the FSA is a limited-purpose FSA covering only dental and vision expenses.
- HSA funds are not lost if you change jobs; the account remains yours.
- FSAs are not free money; they reduce your taxable income, but unused funds can be lost.
FAQs
Q: What if I use HSA money for non-qualified expenses?
A: Withdrawals for non-medical expenses before age 65 incur income tax plus a 20% penalty. After 65, only income tax applies.
Q: Can I contribute to an HSA after enrolling in Medicare?
A: No, Medicare enrollment ends HSA contribution eligibility, but you can still use existing funds.
Q: Can I use my FSA or HSA for my spouse’s medical expenses?
A: Yes, qualified expenses for you, your spouse, and dependents are eligible.
