The FSA grace period is an optional employer feature that gives you up to two and a half extra months after your plan year ends to spend down what’s left in your health care or dependent care flexible spending account. Without it, unspent money is forfeited under the use-it-or-lose-it rule.1Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans For a calendar-year plan, the latest possible deadline is March 15. Your employer can set a shorter window, and some employers don’t offer a grace period at all, so the first thing to do is confirm your plan’s exact date.
How Long the Grace Period Lasts
The grace period comes from IRS Notice 2005-42, which lets employers amend their cafeteria plan to add extra time after each plan year. Two and a half months is the ceiling.2Internal Revenue Service. Notice 2005-42 – Cafeteria Plans Grace Period If the plan year ends December 31, the outside deadline is March 15. If it ends June 30, the outside deadline is September 15.
A grace period, when offered, has to cover every participant in the plan. Your employer can’t extend it to some employees and not others.2Internal Revenue Service. Notice 2005-42 – Cafeteria Plans Grace Period Leftover funds during the grace period can only be spent on the same type of expense they were set aside for. You can’t cash them out or shift them into a different benefit.
Grace Period or Carryover, Not Both
Employers have two tools to soften use-it-or-lose-it, and the IRS bars them from using both on the same FSA in the same plan year.3Internal Revenue Service. Notice 2020-33 – Cafeteria Plans Carryover Modification You don’t get to pick. Your employer chooses one for the whole plan.
With a grace period, your entire remaining balance stays available, but only for a short window. Anything unspent when that window closes is forfeited. With a carryover, a capped dollar amount rolls into the next plan year with no short deadline, but everything above the cap is forfeited. For the 2026 plan year, the carryover cap into 2027 is $680.4FSAFEDS. New 2026 Maximum Limit Updates A grace period tends to help people with larger leftover balances who can realistically spend down within a couple of months; a carryover tends to help people with modest amounts left who want flexibility across the year.
What You Can Spend Grace Period Money On
Eligibility rules don’t change during the grace period. Health care FSA funds still cover things like doctor visit co-pays, prescriptions, dental work, and vision expenses such as glasses and contacts. Over-the-counter medications qualify without a prescription under changes made by the CARES Act, including allergy medicine, pain relievers, cold remedies, and antacids.5FSAFEDS. Over-the-Counter Medicines Eligibility Menstrual care products also qualify.6FSAFEDS. Menstrual Care Products Eligibility General health and cosmetic items don’t.
The critical rule: the expense has to be incurred before the grace period ends. That means the service was actually performed or the item was actually purchased by the deadline. A procedure scheduled for March 20 can’t be paid from prior-year funds if your grace period closed March 15. Booking or paying a deposit isn’t enough. The service has to happen.
Some items require a Letter of Medical Necessity from your doctor. If your administrator asks for one, it needs to identify the patient, the medical condition, and the recommended treatment with frequency and duration.7FSAFEDS. Letter of Medical Necessity Requirements Confirm the required format before the letter is written so you don’t get it rejected.
For dependent care FSAs, eligible expenses during the grace period include daycare, preschool, before- and after-school programs, and day camps for children under 13, plus adult dependent care for a spouse or family member who can’t care for themselves.
The Grace Period Is Not the Same as the Claim Deadline
This is where people lose money. Two separate deadlines apply, and they do different jobs.
The grace period controls when you can incur an expense against prior-year funds. The run-out period controls when you can submit the paperwork for reimbursement. The run-out period typically extends about 90 days beyond the grace period. If your grace period ends March 15, your run-out period might run into June, giving you time to gather receipts for expenses you already incurred. The IRS doesn’t fix a specific run-out length, so ask your administrator.
Most administrators automatically pull from your prior-year balance first when you incur an expense during the grace period, before touching current-year contributions. That’s the right order because it uses the money that’s about to expire. If your plan gives you a debit card, it generally stays active through the grace period and follows the same order. Some plans handle this differently, so it’s worth confirming that prior-year funds are being spent down first.
The HSA Trap
If you have a general-purpose health care FSA with a grace period, you cannot contribute to a Health Savings Account until the first day of the month after the grace period ends. That rule holds even if your FSA balance is zero.8Internal Revenue Service. Notice 2005-86 – HSA Eligibility During Cafeteria Plan Grace Period
For a calendar-year plan with a grace period ending March 15, HSA contributions can’t start until April 1. That’s three months of lost HSA eligibility if you’re moving from a traditional plan to a high-deductible health plan on January 1.
There is a workaround, but your employer has to build it in. The plan can be amended to convert the general-purpose health care FSA into a limited-purpose FSA (dental and vision only) during the grace period. If the conversion applies to every participant with grace period coverage, HSA eligibility is preserved.8Internal Revenue Service. Notice 2005-86 – HSA Eligibility During Cafeteria Plan Grace Period Not every employer offers this. If you’re enrolling in an HSA-qualified plan, raise it during open enrollment.
If You Leave Your Job During the Grace Period
Separating from your employer before the grace period ends creates real problems, and the two account types behave differently.
Health care FSA coverage generally terminates on your last day of employment. Expenses incurred after that date are not reimbursable, no matter what the balance is. You can still file claims for expenses incurred while you were employed, as long as you submit them within the run-out period.9FSAFEDS. What Happens If I Separate or Retire Before the End of the Plan Year
Health care FSAs are treated as group health plans subject to COBRA. If COBRA is offered for your FSA, you can keep participating by paying the full contribution yourself, though FSA COBRA coverage is usually limited to the end of the plan year in which you separated. Whether it’s worth it depends on how much is left in the account relative to the premiums.
Dependent care FSAs work differently. After separation you can generally keep spending down the remaining balance on eligible dependent care expenses through the end of the calendar year. Grace period access for a dependent care FSA typically requires that you were actively employed and contributing through the end of the plan year, though. If you leave before December 31, you may not get the grace period at all.9FSAFEDS. What Happens If I Separate or Retire Before the End of the Plan Year
The One Way to Get Cash Out: Qualified Reservist Distribution
There is a narrow exception to the rule that unused FSA money can’t be paid out to you. Military reservists called to active duty for 180 days or more can request a Qualified Reservist Distribution of the remaining health care FSA balance. Your employer needs a copy of the activation orders, and the request has to be made between the date of the orders and the last day of the plan year or grace period.10Internal Revenue Service. Notice 2008-82 – Qualified Reservist Distributions
The distribution is taxable. It’s added to gross income and reported as wages on your W-2. Employers aren’t required to offer this, so the plan has to be amended to allow it before any payment can be made.10Internal Revenue Service. Notice 2008-82 – Qualified Reservist Distributions
What Happens to Money You Don’t Spend
Once both the grace period and the run-out period close, any remaining balance is permanently forfeited. There’s no reimbursement path, and outside the reservist exception above, no way to receive it as cash.2Internal Revenue Service. Notice 2005-42 – Cafeteria Plans Grace Period
On the employer side, forfeited funds can be kept outright, used to offset plan administration costs, applied to reduce future employee contributions on a uniform basis, or returned to participants on a reasonable and uniform basis. The specifics depend on how the plan is structured. Either way, the money doesn’t come back to you as a refund of your particular unused balance.
The best defense is a conservative election. Base next year’s contribution on what you actually spent over the past two years rather than the maximum allowed. If your plan offers a grace period, factor the extra months into your planning, but don’t treat them as a guarantee you’ll find a way to spend everything. Panic-buying eligible products in March to avoid forfeiting a few hundred dollars is a sign the election was too high to begin with.
