To access your FSA, find the third-party administrator your employer uses, register on that company’s website or mobile app, and from there you can check your balance, use your debit card, and submit claims for reimbursement. Your employer doesn’t run the account directly, so knowing how to access your FSA starts with identifying the administrator that holds it.
Find Out Who Administers Your Account
Your employer selects a third-party administrator to process claims, host your portal, and issue your debit card. Common ones include WEX, HealthEquity, Navia, and Optum Financial, though dozens of smaller companies handle these accounts.
The quickest ways to identify yours:
- Check a recent pay stub. The FSA deduction line often includes the administrator’s name or abbreviation.
- Look at your company’s benefits portal or intranet, which typically lists the administrator with contact details.
- Flip over your health insurance card. The administrator’s logo and phone number often appear there.
- Ask HR or your benefits department for the administrator’s name, website, and phone number.
Once you know the company, every other step runs through their specific platform.
Set Up Your Online Account
Registration on your administrator’s website asks for information that lets the system match you to the enrollment data your employer submitted. You’ll generally need your Social Security number, date of birth, and either an employer ID or group number assigned during benefits enrollment. Some administrators use the last four digits of your SSN instead of the full number, and a few email a registration code during open enrollment that acts as your initial login key.
After the system verifies your identity, you’ll create a username and password. Most platforms also prompt you to set up two-factor authentication, where a code is sent by text or email each time you log in. Treat these credentials the way you’d treat a bank login, because the portal is tied to your SSN and contains medical spending data.
If the administrator offers a mobile app, download it. The app typically mirrors the full portal and lets you photograph receipts on the spot, which saves time later if a charge needs documentation.
What You’ll See on Your Dashboard
After you log in, the dashboard shows your total annual election (the amount you chose to set aside for the year) and your remaining available balance. For a health FSA, the full annual election is available on day one of the plan year regardless of how much has actually been deducted from your paychecks so far. If you elected $3,400 for 2026 and it’s February, you can spend the entire $3,400 even though only a couple of deductions have come through.1Office of the Law Revision Counsel. 26 USC 125 – Cafeteria Plans Your employer bears the risk if you leave before contributing the full amount.
The transaction history section lists every claim: approved, denied, and pending. Check it at least monthly. Automated charges from your FSA debit card sometimes post with vague descriptions, and catching a flagged transaction early keeps your card from being suspended. Most portals also surface deadlines on screen: your plan year end date, any grace or run-out period dates, and document submission deadlines for flagged charges.
If you enrolled in both a health FSA and a dependent care FSA, the dashboard shows them as separate accounts with separate balances. A dependent care FSA only reimburses up to the amount actually contributed so far, so the “available” number works differently from the health account.
Pay With the FSA Debit Card
Most administrators issue a debit card that pulls directly from your account when you pay at a doctor’s office, pharmacy, or medical supply store. The card works like a regular debit card at the point of sale, so you avoid paying out of pocket and waiting weeks for reimbursement. For routine expenses like prescriptions and copays, the transaction often processes without any extra steps on your end.
Behind the scenes, the card system checks the merchant’s category code to confirm the purchase looks like an eligible medical expense. When the code matches a pharmacy, optometrist, or hospital, the transaction is approved automatically. The IRS calls this auto-substantiation, and it’s why a prescription at CVS goes through instantly while a purchase at a retailer that sells both medical and non-medical products might get flagged for additional review.2Internal Revenue Service. IRS Notice 2006-69 – FSA Debit Card Substantiation
If a Transaction Gets Flagged
A flagged transaction isn’t a denial. It means the system couldn’t automatically verify the expense was eligible, and you need to provide documentation. This happens most often at merchants that sell a mix of eligible and non-eligible items, or when a charge doesn’t match a standard copay multiple. Your administrator will notify you by email that a specific transaction needs substantiation.
You’ll typically have about 30 days from that notice to upload a receipt or explanation of benefits showing the date, provider, and amount. If you ignore the request, the administrator must deactivate your card under IRS rules, often around 40 days after the original flagged purchase.2Internal Revenue Service. IRS Notice 2006-69 – FSA Debit Card Substantiation Getting the card reactivated requires submitting the missing documentation or offsetting the unsubstantiated charge with another qualifying expense. This is the single most common reason people lose access to their FSA mid-year, and it’s almost always avoidable by saving receipts from day one.
Submit a Manual Reimbursement Claim
When you don’t use the debit card, because you paid with a personal credit card, the provider didn’t accept the FSA card, or the expense happened before your card arrived, file a claim manually and get reimbursed after the fact.
A valid claim requires documentation showing:
- Date of service: when the appointment, procedure, or purchase occurred.
- Provider or merchant name: the doctor, pharmacy, or supplier.
- Description of service or product: what was provided, not just a dollar amount.
- Amount you owe: your financial responsibility after any insurance adjustments.
An explanation of benefits from your insurance company is the cleanest documentation because it shows all of this in one place. If insurance wasn’t involved, an itemized receipt from the provider works, but it must be itemized. A credit card statement alone will be rejected because it doesn’t describe what was purchased.
Most administrators let you upload documents through the online portal or mobile app, which is the fastest option. Mailing paper forms remains available but adds time. Processing typically takes five to ten business days once the administrator receives your claim, and approved funds are deposited into your bank account or mailed as a check depending on your payment preference.
For questions about whether a specific expense qualifies, most administrator portals include a searchable eligibility tool, and IRS Publication 502 lists the full category of eligible medical expenses.3Internal Revenue Service. Publication 502 – Medical and Dental Expenses
Know the Deadlines That Control Your Access
Access to your FSA money isn’t open-ended. Under the default IRS rule, any money left in your health FSA at the end of the plan year is forfeited.4Internal Revenue Service. IRS Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans The IRS doesn’t require your employer to give you any cushion, and your employer is not allowed to refund unused money back to you.
Most employers soften the deadline by offering one of two options, never both:
- Carryover: up to $680 of unused health FSA funds can roll into the next plan year for 2026. Your employer can set a lower carryover cap, and any amount above the limit is forfeited.5Internal Revenue Service. IRS Notice 2013-71 – Modification of Use-or-Lose Rule for Health FSAs
- Grace period: an extra two and a half months after the plan year ends (typically through March 15 for calendar-year plans) during which you can still incur expenses and have them reimbursed from the prior year’s balance.6U.S. Office of Personnel Management. Is There a Grace Period for FSAFEDS?
Check your plan documents or ask HR which one applies to you, because this detail determines your spending deadline.
Separate from the grace period, most plans include a run-out period, typically 90 days after the plan year ends, during which you can submit claims for expenses you already incurred during the plan year. The run-out period doesn’t extend your spending window; it extends your paperwork window. If your plan year ended December 31 and you had a qualifying expense on December 28 but didn’t submit the receipt yet, you generally have until around March 31 to file that claim. After the run-out period closes, remaining money is forfeited regardless of outstanding receipts.
Accessing Your FSA After You Leave a Job
Your health FSA usually terminates on your last day of employment. You can still submit reimbursement claims for eligible expenses you incurred before that date, but services or purchases after your termination date won’t be covered unless you elect COBRA continuation.7U.S. Department of Labor. COBRA Continuation Coverage
COBRA lets you continue your health FSA through the end of the current plan year, but it only makes financial sense when you’ve contributed more to the FSA than you’ve been reimbursed so far. If you’ve already spent down your balance, there’s no money left to access and the premiums would be wasted. You’d be responsible for the full remaining premium plus a 2% administrative fee, paid entirely out of pocket. You have 60 days from the date your employer coverage ends to decide whether to elect COBRA for your FSA.7U.S. Department of Labor. COBRA Continuation Coverage
Dependent care FSAs work differently. If you leave your job, the balance in your dependent care account generally remains available for reimbursement of eligible expenses incurred anytime during that plan year, even after your employment ends, because dependent care FSAs aren’t treated the same way as health FSAs under COBRA rules.
If you know you’re leaving a job, try to use your health FSA balance before your last day. Schedule dental cleanings, eye exams, or order new glasses. Once you’re gone, that money is extremely difficult to recover without COBRA, and COBRA often isn’t worth the cost.
