FSAFEDS is the Federal Flexible Spending Account Program, a benefit available to federal employees that lets you set aside pre-tax money from your paycheck to pay for health care expenses, dental and vision costs, or dependent care. Because contributions come out before federal income tax and Social Security tax are calculated, most participants save between 20% and 40% on eligible expenses compared to paying out of pocket with after-tax dollars.
The program is administered through the Office of Personnel Management and is open to employees of Executive branch agencies or any agency that has adopted the Federal Flexible Benefits Plan, commonly called FedFlex.
Three Types of FSAFEDS Accounts
FSAFEDS offers three distinct accounts, each covering a different category of expenses. You can enroll in more than one if you’re eligible, but understanding what each covers will help you avoid setting aside money you can’t use.
Health Care FSA (HCFSA)
This is the broadest account. It pays for qualified medical expenses not covered or reimbursed by your FEHB plan or any other health insurance. That includes copays, deductibles, prescription medications, medical devices, and many over-the-counter health products. It is not limited to dental and vision expenses. For 2026, you can contribute up to $3,400 to an HCFSA.
Limited Expense Health Care FSA (LEX HCFSA)
The LEX HCFSA works like the standard health care account but only covers qualifying dental and vision expenses. It exists specifically for federal employees who are enrolled in a high-deductible health plan (HDHP) and contribute to a Health Savings Account (HSA). A regular HCFSA would disqualify you from HSA contributions under IRS rules, so the limited version lets you still get pre-tax savings on dental and vision costs while keeping your HSA intact.
Dependent Care FSA (DCFSA)
This account covers child care or adult dependent care expenses that allow you (or your spouse) to work, look for work, or attend school full-time. Think daycare, after-school programs, summer day camps, or in-home care for an elderly parent who lives with you. The DCFSA does not cover medical expenses for your dependents. One important caveat: if you or your spouse are looking for work but don’t find a job and have no earned income for the year, expenses during that period won’t qualify.
How the Tax Savings Work
When you enroll, you choose an annual contribution amount for each account. That total is divided evenly across your pay periods and deducted before taxes are withheld. If you’re in the 22% federal tax bracket and also pay 7.65% in FICA taxes, every $100 you put into an FSA effectively costs you about $70. The higher your tax bracket, the more you save.
With the HCFSA, your full annual election is available on the first day of the plan year, even though your payroll deductions happen gradually. So if you elect $3,400 for the year, you can use the entire amount in January if you need to. The Dependent Care FSA works differently: you can only claim reimbursement up to the amount that has actually been deducted from your paychecks so far.
Carryover Rules
One of the biggest concerns with any FSA is the “use it or lose it” risk. FSAFEDS addresses this with a carryover provision for health care accounts. For the 2026 plan year, you can carry over up to $680 in unused HCFSA or LEX HCFSA funds into 2027. To qualify for carryover, you must be actively employed by a participating agency and contributing to your account through December 31, and you must re-enroll in an HCFSA or LEX HCFSA for the following year.
The Dependent Care FSA does not have a carryover option. Any unused DCFSA funds at the end of the plan year (plus the grace period for filing claims) are forfeited, so estimate your child care or elder care costs carefully before choosing a contribution amount.
When You Can Enroll or Make Changes
FSAFEDS enrollment happens during the annual Federal Benefits Open Season, which runs from mid-November to mid-December. Elections you make during Open Season take effect on January 1 of the following year. Unlike FEHB coverage, FSA elections do not automatically carry over year to year. You must actively re-enroll each Open Season if you want to continue participating.
Outside of Open Season, you can only enroll or change your election if you experience a qualifying life event, such as marriage, divorce, the birth or adoption of a child, a spouse gaining or losing employment, or a change in your own employment status. You typically have a limited window after the event to make changes.
Filing Claims and Getting Reimbursed
FSAFEDS offers two paths for reimbursement: paperless and manual.
If you opt into paperless reimbursement, your FEHB or FEDVIP plan automatically forwards claims to FSAFEDS each week. Once your health plan submits the claim, it takes roughly 10 to 12 business days for the reimbursement to hit your bank account via direct deposit. This is the simplest option for routine medical, dental, and vision expenses covered under your federal health plan.
For expenses that don’t flow through your insurance, such as over-the-counter products, out-of-network care, or costs your plan doesn’t process, you’ll need to submit a manual claim. Every receipt or Explanation of Benefits (EOB) you submit must include five pieces of information: the patient’s name, the provider’s or merchant’s name, the date of service, a description of the service or product, and the cost. An EOB from your insurance carrier is the easiest documentation to use, especially when insurance covered part of the expense.
Credit card receipts, canceled checks, and balance-forward statements won’t be accepted because they typically lack the required detail. Make sure any receipt you submit is legible, and avoid using highlighters, which can make text unreadable when scanned.
For Dependent Care FSA claims, you have three options: use the FSAFEDS mobile app to have your care provider sign digitally on your device, have the provider sign a paper claim form, or submit the claim with an itemized statement from the provider. The same five documentation requirements apply.
Eligible Expenses at a Glance
- HCFSA: Doctor and specialist copays, prescription drugs, lab work, medical equipment, mental health services, over-the-counter medications, and other IRS-qualified medical expenses not reimbursed by insurance.
- LEX HCFSA: Dental cleanings, fillings, crowns, braces, eye exams, prescription glasses, contact lenses, and other qualifying dental and vision products and services.
- DCFSA: Daycare, preschool, before- and after-school care, summer day camp (not overnight camp), au pair or nanny services, and adult dependent care for a qualifying individual who lives with you.
How Much to Contribute
The right contribution amount depends on how predictable your expenses are. Start by reviewing what you spent out of pocket in the past year on medical costs, dental and vision care, or child care. For the HCFSA, remember that your entire election is available on day one, which is useful if you know you have a procedure scheduled early in the year.
Because the Dependent Care FSA has no carryover, it’s worth being conservative unless you have steady, predictable care costs. If your child ages out of daycare mid-year or your care arrangements change, you could end up with unused funds. For the HCFSA, the $680 carryover cushion gives you a small buffer, but anything beyond that amount is still forfeited if unspent.
A practical approach: total up your expected expenses, subtract any amount your insurance will reimburse, and set your FSA election at or slightly below that number. The tax savings are real, but only on money you actually spend on eligible expenses.
