What a Health Care FSA Covers

A Health Care Flexible Spending Account (FSA) is an employer-sponsored account where you set aside pre-tax money to pay for medical expenses your health insurance doesn't cover or covers only partially. You decide how much to contribute each year during your employer's open enrollment period, and that money sits in the account until you use it for a may have access to expense.

The account covers a wide range of out-of-pocket medical costs: copays, coinsurance, deductibles, prescription medications, dental work, vision care, hearing aids, and medical equipment like crutches or blood pressure monitors. It does not cover health insurance premiums, over-the-counter medications (unless prescribed by a doctor), cosmetic procedures, or gym memberships.

The real benefit is the tax savings. Because FSA contributions come out of your paycheck before taxes, you reduce your taxable income for the year. If you contribute $2,500 to an FSA and your tax rate is 25 percent, you save roughly $625 in federal taxes alone—money you keep instead of sending to the IRS.

Key Takeaways

  • You choose how much to contribute each year during open enrollment, and that money is deducted from your paycheck before taxes.
  • FSA funds cover copays, deductibles, prescriptions, dental, vision, and medical equipment, but not insurance premiums or over-the-counter drugs without a prescription.
  • Money you don't spend by the end of the plan year is forfeited—there is no rollover to the next year, with limited exceptions.
  • You access FSA money through a debit card, reimbursement forms, or direct payment to providers, depending on your plan.
  • You must be enrolled in your employer's health plan to open an FSA, and you can only change your contribution during open enrollment or after a may have access to life event.

How Much You Can Contribute

The IRS sets an annual contribution limit that changes each year. For 2024, the limit is $3,200 per person. Your employer may set a lower limit, but cannot allow you to contribute more than the IRS maximum. You decide your contribution amount during open enrollment and it stays fixed for the entire plan year—you cannot increase or decrease it unless you have a may have access to event like a marriage, birth, job loss, or a change in your spouse's benefits.

The contribution comes out of your paycheck in equal installments throughout the year. If you contribute $2,400 annually and are paid biweekly, roughly $92 comes out each paycheck. This reduces your gross income, which lowers your federal income tax, Social Security tax, and Medicare tax for that year.

The Use-It-or-Lose-It Rule

Any FSA money you do not spend by the end of your plan year is forfeited. If your plan year ends on December 31 and you have $400 left in the account on January 1, that $400 is gone—your employer keeps it. This is the single biggest drawback to FSAs and the reason many people contribute conservatively.

There are two limited exceptions. Some employers offer a grace period of up to 2.5 months into the next year to spend the previous year's money. Others allow you to carry over up to $640 (for 2024) into the next plan year. Your employer chooses whether to offer either option—not all do. Check your plan documents or ask your benefits administrator which applies to you.

Because of this rule, estimate your medical expenses carefully. Look at what you spent last year on copays, prescriptions, and dental work, then contribute an amount you are confident you will use.

How to Access Your FSA Money

Most employers issue an FSA debit card that you swipe at the pharmacy, doctor's office, or medical supplier just like a regular debit card. The card is linked to your FSA account and the purchase is deducted from your balance. Some providers, especially smaller practices, may not accept FSA cards, in which case you pay out of pocket and request reimbursement.

To request reimbursement, you submit a claim form (usually available online through your employer's benefits portal) along with a receipt or explanation of benefits showing the date, provider, and amount of the expense. The FSA administrator reviews the claim and deposits the reimbursement into your bank account, typically within one to two weeks.

Keep all receipts and medical statements for at least three years. The IRS can audit FSA claims, and you must be able to prove that expenses were may have access to and that you paid them out of pocket before being reimbursed.

FSA vs. Health Savings Account (HSA)

FSAs and HSAs are both tax-advantaged accounts for medical expenses, but they work differently. An FSA is offered by your employer and requires you to be enrolled in the employer's health plan. An HSA is available only if you have a high-deductible health plan (HDHP) and can be opened through your employer or independently.

The key difference is rollover. FSA money expires at the end of the year (with limited exceptions). HSA money rolls over indefinitely—you can accumulate it year after year and use it whenever you want, even in retirement. HSAs also allow you to invest the money in stocks and bonds, whereas FSAs are typically held in cash. However, HSAs have lower annual contribution limits than FSAs, and you cannot have both an FSA and an HSA in the same year.

If your employer offers both, an HSA is usually the better long-term choice because the money does not disappear. An FSA makes sense if you have predictable medical expenses each year and want to maximize your tax savings in the short term.

may have access to Life Events and Changes

You can change your FSA contribution only during your employer's open enrollment period, which is usually once a year. However, if you experience a may have access to life event, you can make changes outside of open enrollment. may have access to events include marriage, divorce, birth or adoption of a child, loss of health coverage, a significant change in your spouse's benefits, or a change in your employment status.

You typically have 30 to 60 days from the event to notify your benefits administrator and make changes. If you have a new baby, for example, you may increase your FSA contribution to cover pediatric copays and prescriptions. If you lose your job, you may decrease your contribution or stop contributing altogether.

Common Mistakes to Avoid

The most common mistake is overestimating how much you will spend and losing money at year-end. Contribute only what you are reasonably sure you will use. If you are unsure, start low and increase your contribution next year once you have a year of actual spending data.

Another mistake is forgetting that FSA debit cards sometimes trigger audits. Some providers, especially pharmacies, may ask for a receipt or explanation of benefits to confirm the expense is FSA-may be able to access. Have documentation ready. Do not use your FSA card for ineligible items like cosmetics or vitamins—the transaction may be denied or flagged for review.

A third mistake is not tracking your balance. Log into your FSA account regularly to see how much you have spent and how much remains. This helps you plan your remaining medical expenses for the year and avoid overspending or underspending.
