As tax season rolls around, many of us look for ways to minimize our taxable income and maximize potential savings. If you’ve been offered a Flexible Spending Account (FSA) or a Health Savings Account (HSA) through your employer or are eligible through your health plan, it’s important to understand how these accounts work and how they can benefit you financially. Both FSAs and HSAs allow you to set aside pre-tax money to cover medical expenses, but they each have unique features that could make one more suitable for your needs than the other.
In this post, we’ll break down the key differences between FSAs and HSAs, their eligibility requirements, and the tax benefits they offer, so you can make an informed decision about which one works best for you.
What is a FSA (Flexible Spending Account)?
A Flexible Spending Account (FSA) is an employer-sponsored benefit that allows employees to set aside pre-tax dollars to pay for eligible out-of-pocket medical, dental, and vision expenses. FSAs help reduce your taxable income, which can result in tax savings.
Key Features of FSAs:
- Contribution Limits: In 2025, the maximum annual contribution to an FSA is $3,050 (subject to change annually).
- Use-it-or-lose-it: One of the most important characteristics of an FSA is the “use-it-or-lose-it” rule. Any funds remaining in the account at the end of the year are forfeited, although some plans may allow a small carryover (usually up to $610 for 2025) or offer a grace period.
- Employer-Sponsored: FSAs are typically offered through your employer, and you must enroll during open enrollment periods. You can’t open an FSA independently.
- Eligible Expenses: FSAs can be used for a wide range of medical, dental, and vision costs that aren’t fully covered by insurance, such as copays, prescription medications, dental check-ups, and even over-the-counter medical supplies.
Tax Benefits of an FSA:
- Contributions are made pre-tax, meaning the money you put in the account lowers your taxable income.
- When you use your FSA for eligible expenses, the withdrawals are also tax-free.
How to Use an FSA:
- Reimbursement Process: FSAs usually require you to pay for medical expenses out-of-pocket and submit a claim for reimbursement. Some employers may offer a debit card linked to your FSA account for more convenient transactions.
- Important Considerations: Be mindful of the deadline for using your FSA funds. If you don’t spend the money by the end of the plan year, it’s gone!
- You cannot use FSA funds to pay for insurance premiums. FSAs are designed for qualified medical expenses only, such as copays, prescriptions, and certain medical services.
What is an HSA (Health Savings Account)?
A Health Savings Account (HSA) is another tax-advantaged account for individuals with a high-deductible health plan (HDHP). Like an FSA, you can use an HSA to pay for qualified medical expenses, but an HSA offers more flexibility and long-term savings potential.
Key Features of HSAs:
- Contribution Limits: In 2025, individuals can contribute up to $4,150 to an HSA, while families can contribute up to $8,300. If you’re 55 or older, you can contribute an additional $1,000 as a catch-up contribution.
- Rollover: Unlike an FSA, the money in an HSA rolls over from year to year, so you don’t have to worry about losing any unused funds.
- Ownership: You own the HSA, not your employer. This means you can take it with you if you switch jobs or insurance plans.
- Investment Opportunities: Once your HSA balance grows beyond a certain threshold, you may have the option to invest the funds in stocks, bonds, or mutual funds to help grow your savings for future medical expenses.
Tax Benefits of an HSA:
- Contributions are made pre-tax, reducing your taxable income.
- Withdrawals for eligible medical expenses are tax-free.
- Interest and investment earnings in the account grow tax-free.
- After age 65, you can withdraw funds for any purpose (not just medical expenses) without a penalty, though you’ll pay taxes on non-medical withdrawals.
How to Use an HSA:
- Eligible Expenses: HSAs can be used for a wide variety of qualified healthcare costs, including doctor visits, dental work, vision care, and even some over-the-counter medications. Generally, you cannot use HSA funds to pay for health insurance premiums, except for specific cases like:
- COBRA continuation coverage
- Health insurance while receiving unemployment benefits
- Medicare premiums (but not Medigap)
- Long-Term Savings: Unlike FSAs, HSAs can be used to save for future healthcare needs, making them an excellent option for individuals planning for retirement healthcare costs.
- Investing in Your HSA: After you’ve reached a certain balance, consider investing the funds in your HSA for growth. This could be especially helpful if you don’t anticipate needing to use the funds immediately.
Which One is Right for You?
Deciding between an FSA and an HSA depends on your individual healthcare needs, tax goals, and financial situation. Here’s a quick guide to help you choose:
- Choose an FSA if:
- You have an employer offering an FSA and don’t have a high-deductible health plan (HDHP).
- You want to save on taxes and know you will have enough predictable medical expenses during the year (like copays, dental care, or vision needs).
- You’re comfortable with the “use-it-or-lose-it” rule and can spend the money before the year ends.
- Choose an HSA if:
- You have a high-deductible health plan (HDHP).
- You want to accumulate savings over time for future medical expenses (or even for retirement healthcare costs).
- You want to take advantage of the ability to invest your funds for growth and enjoy tax-free earnings.
Do You Have an HSA or FSA? How Do You Use Them?
If you already have an HSA or FSA, make sure you’re using them to their fullest potential:
- With an FSA:
- Remember to track your eligible expenses throughout the year. Be sure to submit claims for reimbursement before the end of the year or grace period.
- Consider using your FSA for predictable expenses like dental work, eye exams, or prescription glasses.
- With an HSA:
- Maximize your contributions to take full advantage of the tax benefits.
- If you’re not planning on using the funds immediately, consider investing them to grow your savings for future healthcare needs.
- Be aware of your HSA’s rules on withdrawals for non-medical expenses after age 65.
Conclusion
FSAs and HSAs are both excellent tools for reducing taxable income and saving for healthcare expenses, but each offers distinct advantages depending on your healthcare plan and long-term goals. Understanding the differences between these accounts, including contribution limits, eligibility requirements, and tax benefits, will help you make the best choice this tax season and beyond.
