How to Use FSA Funds Before They Expire

If you're staring at a leftover FSA balance in October or November wondering where the year went, you're not alone. Using FSA funds before they expire turns into an annual scramble for millions of account holders, and the confusion around grace periods, carryover limits, and eligible purchases only adds to the pressure.

The good news is that most of that money is still recoverable if you act before your plan's cutoff. Deadlines vary more than people expect. Documentation matters more than people realize. And a durable therapeutic device is usually a smarter buy than a cart full of consumables that run out about as fast as your plan year does.

How FSA Deadlines and Rollovers Actually Work

Flexible Spending Accounts operate on a "use-it-or-lose-it" structure established by the IRS, meaning money you don't spend by your plan's deadline generally reverts to your employer. This rule exists because FSAs offer a tax advantage: contributions come out of your paycheck before taxes are calculated, which lowers your taxable income. In exchange for that upfront benefit, the IRS limits how long unused funds can sit in the account.

The Standard Use-It-or-Lose-It Deadline

Most health FSA plans run on a calendar year, with funds expiring on December 31. Your specific plan year might not align with the calendar year at all. Some employers run FSA plans from July to June or another fiscal cycle, so the deadline that matters to you is the one set by your employer, not a generic date you find online.

The Grace Period Option

The IRS permits employers to offer a grace period of up to two and a half months after the plan year ends, which for a calendar-year plan typically lands around March 15. During this window, you can continue spending prior-year funds as if the plan year hadn't ended. Not every employer offers this option, so check your plan documents or ask your HR or benefits administrator directly.

The Carryover Option

Instead of a grace period, some employers allow a limited carryover of unused funds into the next plan year. The IRS adjusts this carryover limit periodically, and it has recently sat in the $640 to $660 range. A plan can offer a grace period or a carryover, but not both, so it pays to know which structure your employer uses before you assume your money is safe.

• Standard deadline: funds expire at the end of the plan year with no extension
• Grace period: up to 2.5 extra months to spend prior-year funds
• Carryover: a capped dollar amount moves into the next plan year
• No extension at all: some employers choose none of the above, so confirm your specific plan

Checking Your Remaining FSA Balance

Before you can plan a year-end purchase, you need an accurate number. Most FSA administrators offer an online portal or mobile app where you can view your current balance in real time. Your balance typically reflects your total annual election minus any claims already reimbursed or debit card purchases already made.

• Log into your FSA administrator's portal or mobile app for a real-time balance
• Check a recent pay stub for year-to-date FSA contributions and compare it against your spending records
• Call the customer service number printed on the back of your FSA debit card
• Ask your HR or benefits contact for written confirmation of your balance and deadline

Do this in October or early November rather than waiting until the final week of December. Some eligible purchases and manual reimbursement claims take days or weeks to process, and a claim submitted on December 30 may not clear in time.

What Counts as an FSA-Eligible Purchase

Not everything you might want to buy qualifies, and the IRS maintains specific rules about what an FSA can reimburse. Eligible expenses generally include medical care, dental and vision costs, prescribed treatments, and certain medical equipment. Over-the-counter items and some therapeutic devices also qualify, though the rules around "dual-purpose" items (things that could serve general wellness or a specific medical purpose) tend to be stricter.

Durable Devices vs. Consumable Items

A common year-end mistake is spending FSA funds on small consumables, like bandages or a few bottles of contact solution, simply because the deadline is looming. A more strategic approach is to put remaining funds toward a durable item you'll use for years. A therapeutic massager built for long-term use, whether that's a foot unit or a full-size body massager for larger muscle groups, fits that category well, since it addresses an ongoing need rather than a one-time purchase.

Vibration-based massage tools come up frequently in FSA spending searches, and many people specifically look for a vibration foot massager when researching eligible purchases. MedMassager uses oscillating technology to deliver deeper, more controlled vibration than conventional massagers, which is part of why customers choose it as a year-end FSA purchase over a basic vibrating unit. Browsing a collection of therapeutic foot massagers before your deadline gives you time to compare models and confirm eligibility instead of rushing a decision on December 30.

The Truemed Qualification Path

Some FSA-eligible purchases require a Letter of Medical Necessity to qualify, especially items that could be viewed as general wellness products rather than medical devices. Truemed is a third-party service that many retailers, including MedMassager, integrate into checkout. It determines whether a specific purchase qualifies for FSA or HSA reimbursement based on your answers to a short eligibility questionnaire. If a product qualifies through this path, Truemed can generate the documentation that supports your claim, which removes much of the guesswork around reimbursement.

Documentation to Keep

Whatever you purchase, hold onto your records. FSA administrators can request substantiation for any claim, and without proper documentation, a reimbursement can be reversed after the fact.

• Itemized receipts showing the product name, date, and cost (a credit card statement alone usually isn't sufficient)
• Any Letter of Medical Necessity or Truemed eligibility documentation, if applicable
• Written confirmation of your plan's exact deadline, grace period, or carryover terms
• A copy of the claim submission and reimbursement confirmation, if you paid out of pocket instead of using an FSA debit card

How to Spend FSA Funds Before They Expire

Waiting until the last week of the plan year to figure out your balance is the single most common reason people lose FSA money. A little planning in October or November avoids that outcome entirely.

1. Log into your FSA administrator's portal and confirm your exact remaining balance and plan deadline.
2. Ask HR or your benefits administrator whether your plan includes a grace period, a carryover limit, or neither.
3. Review the IRS eligible expense list, or check with your administrator, to identify qualifying purchases in categories relevant to you.
4. Prioritize durable, higher-value items over small consumables when your balance allows, since a single well-chosen purchase is easier to document than a dozen small ones.
5. If you're considering a therapeutic device, check whether the retailer offers a Truemed or similar qualification path at checkout to confirm eligibility before you buy.
6. Keep every receipt and confirmation email in one folder until your claim is fully processed and reimbursed.
7. Submit any manual claims well before your deadline, since processing time can eat into the final days of a grace period.

Special Considerations for Different FSA Types

Not all FSAs work identically, and mixing up the rules between account types is another common source of year-end confusion.

• Health FSA: medical, dental, and vision expenses
• Dependent Care FSA: childcare and eldercare costs, under separate eligibility rules
• Limited-Purpose FSA: dental and vision only, designed to pair with an HSA

Health FSA vs. Dependent Care FSA

A standard health FSA covers medical, dental, and vision expenses, while a Dependent Care FSA covers childcare or eldercare costs and follows entirely separate eligibility rules. Funds in one account cannot cover expenses meant for the other. Double-check which account your remaining balance sits in before making assumptions about what qualifies.

Limited-Purpose FSAs Paired with an HSA

If you contribute to a Health Savings Account, your employer may also offer a Limited-Purpose FSA that covers only dental and vision expenses, preserving your HSA funds for broader medical use. These accounts still follow use-it-or-lose-it timing, so the same deadline awareness applies even though the eligible expense list is narrower.

Job Changes Mid-Year

Leaving an employer typically forfeits any unused FSA balance unless you elect COBRA continuation for your FSA specifically, which is uncommon but sometimes available. If you know a job change is coming, accelerate your spending plan rather than assuming the balance follows you. In most cases, it won't.
