FSA money does not roll over to the next year — you lose what you don't spend

Flexible Spending Accounts (FSAs) operate under a "use-it-or-lose-it" rule. Any money you contribute but don't spend on may have access to medical expenses by the end of the plan year is forfeited. You cannot move the balance to a savings account, an IRA, a health savings account, or next year's FSA. The money goes back to your employer.

There is one narrow exception: a grace period of up to 2.5 months into the next calendar year, which some employers offer. If your plan includes this, you can spend money from the previous year's FSA during that window. Not all employers offer it, and the rules vary by plan.

Because FSA money disappears if unused, the account works differently from retirement accounts. You need to estimate your medical spending carefully each year and contribute only what you will actually use.

Key Takeaways

  • FSA balances do not carry forward to the next plan year under the standard use-it-or-lose-it rule, and you forfeit any unspent money.
  • A grace period of up to 2.5 months into the following year may allow you to spend previous-year FSA funds, but only if your employer's plan includes this option.
  • You cannot transfer FSA money to an IRA, a health savings account, or any other account type.
  • If you leave your job, your FSA balance is forfeited unless you have already incurred the expenses — you cannot take the money with you.
  • Estimating your annual medical costs accurately is the only way to avoid losing money, since you cannot adjust your contribution mid-year except during open enrollment or after a may have access to life event.

The grace period: how it works and whether your plan has one

A grace period is an optional feature that employers can add to their FSA plan. If included, it extends the spending window into the next calendar year — typically 2.5 months (through March 15 if the plan year ends December 31). During this time, you can use money from the previous year's FSA to pay for medical expenses incurred in that previous year.

The grace period does not let you spend money on current-year expenses using old-year funds. The expense must have occurred in the year the money was set aside. You also cannot carry over a grace period balance itself — if you don't spend the old money during the grace period, it is gone.

To find out whether your plan has a grace period, check your Summary of Benefits and Coverage (SBC) or the plan document your employer provided. You can also ask your benefits administrator or HR department directly. If your plan does not mention a grace period, assume you do not have one.

What happens to your FSA when you change jobs

If you leave your job before the end of the plan year, your FSA account closes immediately. Any unspent balance is forfeited, even if you have already incurred medical expenses that you planned to pay with that money. The only exception is if you have already submitted claims for expenses — those may be paid out before your account closes, depending on your plan's rules.

You cannot roll an FSA into a new employer's FSA, an IRA, or a health savings account. The money simply reverts to your former employer's plan. This is one of the biggest risks of FSA accounts: a job change mid-year can mean losing a significant balance.

If you are planning to leave a job, try to spend down your FSA balance before your last day. Pay out-of-pocket for medical expenses you know are coming, then submit the receipts to your FSA for reimbursement. This is one of the few ways to recover money that would otherwise be lost.

FSA vs. HSA: which account lets you keep unused money

A Health Savings Account (HSA) is fundamentally different from an FSA because it does roll over. Any money you contribute to an HSA stays in the account year after year. You can let it grow, invest it, and spend it whenever you need to — even in retirement. There is no use-it-or-lose-it rule.

However, you can only open an HSA if you are enrolled in a high-deductible health plan (HDHP). FSAs are available to people on any health plan. If your employer offers both, an HSA is generally the better choice for long-term savings because the money is yours to keep.

Some employers offer both an FSA and an HSA. If yours does, you can contribute to both in the same year, but there are contribution limits and coordination rules. Talk to your benefits administrator about whether this makes sense for your situation.

How to estimate your FSA contribution and avoid losing money

The key to using an FSA without waste is estimating your medical spending accurately. Look at the past year's receipts: copays, deductibles, prescriptions, dental work, vision care, and other out-of-pocket costs. Add up what you actually spent, then use that as a baseline for the coming year.

Be conservative. If you spent $1,200 last year but had an unusual procedure, don't assume you'll spend that much again. If you spent $800 and expect a similar year, contribute $800 to $900 — not $1,500. Overestimating is the most common mistake.

Remember that FSA money can only pay for may have access to medical expenses as defined by the IRS. These include copays, deductibles, prescription drugs, dental work, vision care, and certain medical equipment. They do not include health insurance premiums (with narrow exceptions), cosmetic procedures, or over-the-counter medications without a prescription. Check the IRS Publication 502 for the full list, or ask your FSA administrator which expenses may have access to.

You can change your FSA contribution during open enrollment each year, or if you have a may have access to life event (marriage, birth, loss of coverage, significant change in health care costs). Outside these windows, you are locked into your contribution for the year.

Strategies to spend down your FSA before year-end

If you have unspent FSA money with a few months left in the plan year, you have time to use it. Stock up on prescription refills, schedule dental cleanings or eye exams, buy over-the-counter items that may have access to (with a prescription), or pay for medical services you have been putting off.

Many people use their FSA to pay for items they would buy anyway — glasses, contacts, hearing aid batteries, or medical equipment. This is not wasteful; it is the intended use. You are simply paying for necessary expenses with pre-tax money instead of after-tax dollars.

If you are close to year-end and still have a large balance, contact your FSA administrator or benefits team. They can tell you exactly how much time you have left and whether a grace period applies. Some plans also allow a small carryover (up to $570 in 2024, though this varies by year and plan type), though this is less common than the grace period.

What to do if you lose FSA money due to job loss or life changes

If you lose your job or experience a major life change that forces you to forfeit FSA money, there is no way to recover it. The money is gone. This is a hard rule of FSA accounts, and it is one reason some people avoid them entirely.

The best protection is to contribute conservatively and keep receipts for all medical expenses. If you leave your job mid-year, try to submit claims for expenses you have already incurred before your account closes. Some plans allow a brief window for this.

Going forward, consider whether an HSA (if you are may be able to access) might be a better fit for your situation. An HSA offers the same tax advantages as an FSA but without the use-it-or-lose-it risk. If your employer offers both, weigh the trade-offs: an FSA is useful if you have predictable, high medical expenses each year; an HSA is better if you want to build savings over time.

Frequently Asked Questions

Can I transfer my FSA balance to my spouse's FSA?

No. FSA balances cannot be transferred between spouses, even if you file taxes jointly. Each FSA account is separate, and any unspent balance is forfeited at year-end. If both you and your spouse have FSAs, you each need to manage your own contribution and spending.

What if my employer offers a carryover instead of a grace period?

Some plans allow you to carry over up to a certain amount (typically $570 in 2024, though this changes annually) to the next plan year. This is different from a grace period and is less common. Check your plan document to see if a carryover is available. If it is, any amount over the carryover limit is still forfeited.

Can I get my FSA money back if I don't use it?

No. Once the plan year ends and any grace period expires, unspent FSA money is forfeited. You cannot request a refund, and the money does not go to your employer as income — it stays in the plan to offset administrative costs or reduce future contribution rates for all employees.

Do FSA funds roll over if I'm on COBRA?

No. If you elect COBRA coverage after leaving your job, your FSA does not continue. Your FSA account closes when your employment ends, and any remaining balance is forfeited. COBRA only covers health insurance, not FSA accounts.

What happens to my FSA if I take unpaid leave or go on disability?

This depends on your employer's plan and whether you remain an active employee. If you stop paying premiums or are no longer considered an active participant, your FSA may close. Contact your HR or benefits department immediately if you are taking leave or going on disability to understand how it affects your FSA.
