FSAFEDS in your final working year
It ends the day you retire. The full election is yours from day one.
Size the election to your expenses before your last day, not for the full year. Anything you incur after retiring is not reimbursable, even with money left in the account.

1. Why it ends when you retire
A flexible spending account lets you set aside salary before tax to pay eligible expenses. An annuity is not salary. So by law, annuitants cannot participate in FSAFEDS — the only exception is a reemployed annuitant who is eligible through current employment.
That means your health care FSA, or limited expense health care FSA, terminates on your retirement date. There are no extensions. Expenses you incur up to that date are reimbursable; expenses incurred afterward are not, even if money is still in the account.
You can still enroll for a year in which you plan to retire. You participate until your retirement date, and then it stops. OPM's own guidance is to calculate your expected eligible expenses up to that date, not for the whole year.
2. The rule that works in your favor
This is the part most retirement checklists miss, and it turns the FSA from a forfeiture risk into an advantage.
Your entire annual health care FSA election is available from the start of the plan year, even though it comes out of your pay a little at a time. And FSAFEDS states that if you use your entire elected amount before it has all been deducted from your pay, you are not responsible for the remaining allotments.
| Example: $3,000 election, retiring June 30 | Amount |
|---|---|
| Deducted from pay January–June | About $1,500 |
| Eligible expenses incurred and claimed by June 30 | $3,000 |
| Reimbursed to you | $3,000 |
| Remaining allotments you owe after retiring | $0 |
The reverse is where people lose money. Contribute steadily, plan to spend it "later in the year," and retire before you do — and whatever you haven't spent on pre-retirement expenses is gone.
If you have predictable expenses — a planned procedure, new glasses, dental work, a year of prescriptions — schedule them before your retirement date. The timing of the expense is what matters, not the timing of the deduction.
3. Sizing the election in your retirement year
- Estimate eligible expenses you will incur before your last day — copays, deductibles, prescriptions, dental, vision, and eligible over-the-counter items.
- Elect that amount, not a full-year figure. A retirement in March justifies a much smaller election than one in December.
- Pull predictable expenses forward into the months before you retire.
- Don't count on the carryover. Carrying unused money into the next year requires an active account on December 31 and re-enrollment at Open Season. A retiree has neither.
- Watch the 2027 limit. The IRS sets the next year's limit later in the fall; the 2026 health care FSA limit is $3,400.
If you are retiring on December 31, the question mostly disappears — your participation runs the full year. For a mid-year date, sizing is the whole game. The date choice itself is covered in best dates to retire in 2027.
4. The dependent care FSA is different
A dependent care FSA does not stop the same way. After you separate, you can keep using the remaining balance for eligible dependent care expenses until it runs out or the calendar year ends, whichever comes first. There is no grace period after the plan year, and claims are still due by April 30 of the following year.
5. What to do before your last day
- Check your balance at fsafeds.gov a few months out.
- Schedule remaining care — appointments, glasses, prescriptions — before your retirement date.
- Buy eligible over-the-counter items you will use anyway, such as first-aid supplies and SPF 15+ sunscreen.
- Submit claims for past expenses you haven't filed yet, including eligible travel costs for medical appointments.
- Keep receipts and diary April 30 of the following year as your final claims deadline.
The FSA is one of several things that end or change at retirement. FEHB continues if you meet the five-year rule, but your premiums move from pre-tax to after-tax; see the five-year rule and the full sequence in the retirement countdown.
6. Frequently asked questions
Can I keep my FSAFEDS account after I retire?
No. By law, annuitants cannot participate in flexible spending accounts, because an FSA sets aside pre-tax salary and an annuity is not salary. The one exception is a reemployed annuitant who is eligible through current employment. Your health care FSA ends on your retirement date, with no extension.
What happens to money left in my health care FSA when I retire?
Expenses you incur up to your retirement date are reimbursable; expenses incurred after it are not, even if money remains in the account. You have until April 30 of the following year to submit claims for expenses incurred before you separated. Anything not claimed by then is forfeited to the program administrator.
Can I spend my whole annual election before I retire?
Yes. Your full annual health care FSA election is available from the start of the plan year, even though it is deducted from your pay in installments. If you use the entire elected amount before it has all been deducted, you are not responsible for the remaining allotments. For someone retiring mid-year, this means the election works in your favor if you plan expenses before your last day.
Does the carryover help me if I retire?
Generally no. To carry unused health care FSA money into the next year you must have an active account on December 31 and re-enroll during Open Season. A retiree has neither, so the carryover does not apply. Treat the balance as use-it-or-lose-it by your retirement date.
What about a dependent care FSA?
It is treated differently. After you separate you can keep using a dependent care FSA balance for eligible dependent care expenses until the balance runs out or the calendar year ends, whichever comes first. There is no grace period after the plan year, and claims are due by April 30 of the following year.
