A FIA account is a tax-advantaged savings account that lets you set aside pre-tax money for specific out-of-pocket medical, dependent care, or transit expenses.

FIA stands for Flexible Spending Account. Your employer deducts money from your paycheck before taxes are taken out, and you use that money to pay for may be able to access expenses. The main benefit is that you avoid federal income tax, Social Security tax, and Medicare tax on the money you contribute — which typically saves you 20 to 40 percent depending on your tax bracket.

FIA accounts come in three types: healthcare FSA (for medical and dental costs), dependent care FSA (for childcare or adult daycare), and transit FSA (for commuting costs like bus passes or parking). You choose which type you need, decide how much to contribute each year, and the money sits in an account you draw from as you incur expenses.

The catch is that FIA accounts operate on a "use it or lose it" rule in most cases. Money you don't spend by the end of the plan year (usually December 31) goes back to your employer — you forfeit it. Some employers offer a grace period of up to 2.5 months into the next year, or let you carry over up to $610 (as of 2024), but you need to check your specific plan.

Key Takeaways

  • FIA accounts let you pay for may be able to access medical, dependent care, or transit expenses with pre-tax money, saving you roughly 20 to 40 percent in taxes.
  • You enroll during your employer's open enrollment period (usually once a year), choose an account type, and set a contribution amount that stays fixed for the plan year.
  • Money you don't spend by the end of the year is forfeited unless your employer offers a grace period or carryover option.
  • You access FIA money through a debit card, reimbursement request, or direct payment to providers, depending on what your plan allows.
  • FIA accounts are separate from Health Savings Accounts (HSAs) and Dependent Care Accounts (DCAs), though some people use both.

How you enroll and set your contribution

You can only sign up for a FIA account during your employer's open enrollment period, which typically happens once a year in the fall for coverage starting January 1. If you're a new employee, you usually have 30 to 60 days from your hire date to enroll. You cannot open a FIA account on your own — it must be offered through your employer's benefits plan.

When you enroll, you decide how much to contribute for the entire plan year. For 2024, the maximum contribution to a healthcare FSA is $3,300, and for dependent care FSA it's $5,000 (or $2,500 if you're married filing separately). You can't change your contribution amount mid-year unless you have a may have access to life event — marriage, birth of a child, loss of other coverage, or significant change in childcare costs.

Your employer deducts your chosen amount from your paychecks in equal installments throughout the year. If you contribute $2,400 to a healthcare FSA and get paid biweekly, roughly $92.31 comes out of each paycheck before taxes.

What expenses you can pay for with each account type

Healthcare FSA covers medical, dental, and vision expenses that aren't covered by your insurance or that you pay out of pocket. This includes copays, coinsurance, deductibles, prescription medications, glasses, contact lenses, dental work, and hearing aids. It does not cover insurance premiums, over-the-counter medications (unless prescribed), or cosmetic procedures. The IRS publishes a full list of may be able to access expenses on its website.

Dependent Care FSA pays for childcare or adult daycare expenses so you can work. This includes daycare centers, in-home babysitters, preschool, after-school programs, and adult day programs for a parent or disabled spouse. It does not cover overnight camps, tuition for kindergarten or higher grades, or babysitting for social outings. The person receiving care must be your dependent under IRS rules.

Transit FSA covers commuting costs: public transportation passes, vanpool fees, and parking at a transit station or your workplace. It does not cover gas, car maintenance, or parking at home. The maximum contribution for transit FSA in 2024 is $315 per month.

How to access and use your FIA money

Most healthcare FSAs come with a debit card that you can swipe at pharmacies, doctors' offices, and other providers. The card is linked to your account balance, and you can use it up to your available funds. Some plans require you to submit a receipt or claim form after you pay out of pocket, and the plan reimburses you.

Dependent care and transit FSAs typically require you to submit a claim or reimbursement request with receipts or proof of payment. You fill out a form (usually available online through your benefits portal), attach documentation, and the plan sends you a check or direct deposit within a few business days.

Keep all receipts and documentation. Your plan administrator may ask you to prove that an expense was may be able to access, especially if you use the debit card. If you can't provide proof, you may have to repay the money to the plan.

The use-it-or-lose-it rule and how to avoid forfeiting money

Under IRS rules, money left in your FIA account at the end of the plan year is forfeited — you lose it. This is the biggest risk of opening a FIA account. If you contribute $2,500 and only spend $1,800, the remaining $700 goes back to your employer.

Some employers offer a grace period of up to 2.5 months into the next year. If your plan has a grace period, you can spend money from the prior year's account through that date. Other employers allow you to carry over up to $610 (as of 2024) to the next year's account. A few plans offer both. Check your plan documents or ask your benefits administrator which option applies to you.

To avoid forfeiture, estimate your expenses conservatively. If you're unsure whether you'll spend the full amount, contribute less. You can also front-load predictable expenses — if you know you'll need glasses this year, buy them early and submit the claim before year-end.

FIA accounts versus HSAs and other savings accounts

A Health Savings Account (HSA) is different from a healthcare FSA. An HSA is only available if you're enrolled in a high-deductible health plan (HDHP), and it has no use-it-or-lose-it rule — money rolls over year to year and grows tax-free. You can also invest HSA funds and withdraw them in retirement for any purpose. However, HSAs have lower contribution limits ($4,150 for individual coverage in 2024) and require you to be in an HDHP.

A Dependent Care Account (DCA) is sometimes used interchangeably with dependent care FSA, but they're technically the same thing — both are pre-tax accounts for childcare expenses.

You can have both a healthcare FSA and an HSA if your employer offers both and you're may be able to access, but you cannot have two healthcare FSAs at the same time, even if you have two jobs.

What happens if you leave your job or change plans

If you leave your job, your FIA account closes. You forfeit any unused balance unless your employer's plan allows a continuation period (rare). You have until the end of the plan year to submit claims for expenses you already incurred while employed.

If you change jobs and your new employer offers a FIA, you can enroll in the new plan during your new-hire enrollment window. Your old account and new account are separate — money doesn't transfer.

If you change to a different health plan within the same employer, you may be able to change your FIA contribution amount if the change is tied to a may have access to life event. Otherwise, your contribution stays the same for the rest of the plan year.

Frequently Asked Questions

Can I use my FIA debit card at any store?

No. The debit card only works at pharmacies, medical providers, and other vendors that accept FSA cards and sell may be able to access items. If you try to use it at a grocery store or gas station, it will be declined. Some online pharmacies and medical retailers accept FSA cards, but you need to check first.

What happens if I submit a claim for an ineligible expense?

Your plan administrator will deny the claim and ask you to resubmit with an may be able to access expense or documentation proving the expense qualifies. If you've already been reimbursed for an ineligible expense, you may have to repay the plan. Repeated errors can trigger an audit of your account.

Can I change my FIA contribution mid-year?

Only if you have a may have access to life event: marriage, divorce, birth or adoption of a child, loss of other health coverage, or a significant change in dependent care costs. You must request the change within 30 to 60 days of the event. Job changes or raises do not may have access to.

What if my employer doesn't offer a FIA?

You cannot open a FIA on your own. If your employer doesn't offer one, you can explore an HSA if you're in a high-deductible health plan, or simply pay for may be able to access expenses with after-tax money. Self-employed people cannot open a FIA but may be able to open an HSA.

Do I pay taxes on FIA money when I withdraw it?

No. The money is deducted before taxes are calculated, so you never pay federal income tax, Social Security tax, or Medicare tax on it. You only pay taxes on money you actually spend on may be able to access expenses — the rest is forfeited.
