Use It or Lose It: Spending 2026 FSA Dollars on Eye Surgery

LASIK and other vision-correcting surgery are eligible health FSA expenses. The catch is timing: the surgery itself, not the bill, has to land inside your plan year.

Yes, you can generally use a health FSA for LASIK and other vision-correcting eye surgery. IRS Publication 502 lists eye surgery to treat defective vision, including laser eye surgery, as a medical expense. For 2026 plans, you could set aside up to $3,400, and only up to $680 can roll into 2027 if your plan allows carryover.

If you still have a large 2026 balance, a December procedure can put it to work. This guide covers the rules, the deadlines and the timing traps.

What the IRS says about eye surgery

Health FSAs reimburse expenses that would generally qualify for the medical expense deduction. IRS Publication 969 says that directly. The list of what qualifies lives in IRS Publication 502.

Pub 502's "Eye Surgery" entry says you can include the amount you pay for eye surgery to treat defective vision. It gives laser eye surgery and radial keratotomy as examples. Its "Vision Correction Surgery" entry points back to the same place.

That language covers the common refractive procedures people ask about, as long as the purpose is correcting vision. Pub 502 also lets you include eyeglasses and contact lenses needed for medical reasons, plus contact lens supplies like saline solution.

What does not qualify

Pub 502 says cosmetic surgery generally is not a medical expense. The exceptions are surgery to correct a deformity from a congenital condition, an injury or a disfiguring disease. Cosmetic eyelid work, for example, would usually fall on the wrong side of that line unless it fixes a medical problem.

Your plan document can also be narrower than Pub 502. Plans reimburse expenses "specified in the plan." If you are unsure, ask your FSA administrator before you book.

2026 limits: $3,400 in, $680 out

Each year the IRS adjusts the health FSA limits for inflation. Revenue Procedure 2025-32, section 4.15, sets the numbers for plan years beginning in 2026:

• $3,400 maximum employee salary reduction into a health FSA.
• $680 maximum carryover of unused amounts, if your plan allows carryover.

Your employer can set lower limits. The carryover cap is a ceiling, not a guarantee. When we checked the IRS newsroom on October 30, 2026, the 2027 health FSA figures had not been announced. Use your employer's enrollment materials for the 2027 amount once it is published.

Grace period vs carryover: know which one you have

IRS Publication 969 describes health FSAs as generally use-it-or-lose-it. Your plan can soften that in one of two ways, but not both.

Some plans offer neither. In that case, anything you have not spent on care received by the end of the plan year is forfeited.

Your plan may also have a run-out period, a window after year-end to submit claims for care you already received. That is different from a grace period. It does not let you have new procedures; it only gives you time to file paperwork. Check your plan's exact deadline.

Timing a December surgery

The rule that trips people up: Pub 969 says FSA distributions reimburse expenses incurred during your period of coverage. The proposed IRS regulations on cafeteria plans (Prop. Treas. Reg. §1.125-6) treat a medical expense as incurred when the care is provided. It is not when you are billed, charged or pay.

So a deposit paid in December for a January surgery generally does not count against your 2026 balance. The procedure itself has to happen inside the 2026 plan year, or inside your grace period if your plan has one.

Steps to make a December date work

1. Check your balance and plan type. Log in to your FSA account. Note your remaining 2026 balance and whether you have a grace period, carryover or neither.
2. Book the consultation now. Refractive surgery usually needs a full eye exam and measurements first. The FDA advises contact lens wearers to switch to glasses before the baseline evaluation: 2 weeks for soft lenses, at least 3 weeks for toric soft or rigid gas permeable lenses, and at least 4 weeks for hard lenses. Count those weeks backward from December.
3. Ask for the surgery date in writing. Confirm the procedure date, not just a consult date, falls on or before your plan's last day.
4. Get an itemized receipt. It should show the patient's name, date of service, provider, procedure and amount. Administrators use it to substantiate the claim.
5. Pay with the FSA card or file a claim. If the card is declined or you pay another way, submit a claim with the itemized receipt.
6. File before the run-out deadline. Even with the surgery done in time, a late claim can be denied.

Recovery time matters too, especially around holiday travel. Our recovery timeline for every procedure shows typical follow-up visits and downtime.

Plan your 2027 election around the surgery

If you cannot fit surgery into 2026, open enrollment for 2027 is your next lever. Two IRS rules help.

Uniform coverage. Pub 969 says you must be able to receive your full annual election at any time during the coverage period, regardless of how much you have contributed so far. Elect enough for 2027 and you can have surgery in January, before the payroll deductions add up.

Treat open enrollment as the decision point. Employer plans restrict when you can change an FSA election once the year starts. Check your plan's rules, and set the amount you want before enrollment closes.

One more interaction: Pub 969 says that if you are covered by a high-deductible health plan and a general health FSA, you generally cannot contribute to an HSA. Pub 969 names limited-purpose FSAs as an exception. If you have an HSA, ask your employer whether it offers one and what it covers.

Using FSA money for surgery outside the US

Some readers compare US LASIK prices with options in Colombia. Pub 502 defines medical expenses as payments for legal medical services from physicians, surgeons and other practitioners. It does not exclude care received abroad for the taxpayer.

The practical hurdle is substantiation. Your FSA administrator decides what documentation it accepts. Before booking, ask whether it will accept an itemized receipt from a foreign clinic, in what language and currency, and whether it needs a translation.

Travel costs are a separate question. Pub 502 allows some transportation and limits lodging to $50 a night per person under specific conditions. Whether your FSA plan reimburses travel at all depends on the plan. Our LASIK in Colombia guide covers the clinical side of that choice.

The bottom line

Laser and other vision-correcting eye surgery is a standard FSA expense under IRS rules. The money is not the hard part; the calendar is.

Confirm your plan's grace period or carryover, get the surgery itself done inside the plan year, and keep the itemized receipt. If 2026 is too tight, set your 2027 election during open enrollment so the full amount is ready in January.
