Laser eye surgery is tax deductible as a qualified medical expense under IRS rules, but most people who pay for LASIK or PRK won’t actually save anything on their federal return by claiming it. The deduction only reaches expenses above 7.5% of your adjusted gross income, and only if you itemize. For a planned procedure, paying through an HSA or FSA usually delivers a bigger and more reliable tax benefit than the itemized deduction ever will.
Yes, the IRS Treats It as a Medical Expense
Publication 502 explicitly lists eye surgery to correct defective vision, including laser eye surgery, as a qualified medical expense.1Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses The governing statute, 26 U.S.C. ยง 213, defines deductible medical care as amounts paid to treat disease or to affect any structure or function of the body.2Office of the Law Revision Counsel. 26 USC 213 – Medical, Dental, Etc., Expenses Corrective vision surgery treats a functional impairment, so it qualifies.
Related costs feed into the same pool: pre-operative exams, post-operative care, prescription eyeglasses, contact lenses, and vision insurance premiums.1Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses
Why the Deduction Usually Produces Nothing
Qualifying is the easy part. Getting an actual tax benefit is where things fall apart for most filers.
The 7.5% AGI Floor
You can only deduct the portion of your qualified medical expenses that exceeds 7.5% of your adjusted gross income.3Internal Revenue Service. Topic No. 502, Medical and Dental Expenses Your AGI sits on line 11 of Form 1040.4Internal Revenue Service. Adjusted Gross Income
Consider a married couple with an AGI of $150,000. Their floor is $11,250. If their total qualified medical expenses for the year, LASIK included, add up to $9,000, they deduct nothing. If they hit $15,000 in total expenses, only $3,750 is deductible. LASIK typically runs between $1,500 and $5,000 per eye, so the surgery on its own may not clear the floor unless the same year brings other significant medical costs.
Even after clearing the floor, the savings depend on your marginal rate. That $3,750 deduction is worth about $900 to a couple in the 24% bracket. The 7.5% threshold was made permanent in 2020, so it isn’t scheduled to change.
You Also Have to Itemize
The medical expense deduction only exists on Schedule A. Take the standard deduction and it’s gone.5Internal Revenue Service. Tax Basics – Understanding the Difference Between Standard and Itemized Deductions For 2026, the standard deduction amounts are:6Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- Single filers: $16,100
- Married filing jointly: $32,200
- Head of household: $24,150
A married couple needs more than $32,200 in combined itemized deductions before itemizing does anything at all. State and local taxes, mortgage interest, charitable giving, and whatever medical expenses survive the 7.5% floor all have to add up past that number. For most households, they don’t.
The Better Route: HSAs and FSAs
Pre-tax accounts sidestep the whole itemizing problem. Money goes in untaxed, comes out untaxed for qualified expenses like laser eye surgery, and there’s no AGI floor to clear. If you’re planning surgery, this is usually where the tax benefit actually lives.
Health Savings Accounts
An HSA gives you three tax advantages at once: contributions are pre-tax or deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. Laser eye surgery qualifies. You need to be enrolled in a High Deductible Health Plan, which for 2026 means a minimum annual deductible of $1,700 self-only or $3,400 family.7Internal Revenue Service. Revenue Procedure 2025-19
The 2026 contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, with an extra $1,000 catch-up if you’re 55 or older.7Internal Revenue Service. Revenue Procedure 2025-19 Unused funds roll over year to year, so you can build a balance across a couple of years before scheduling surgery.
Flexible Spending Arrangements
An FSA is an employer-sponsored account funded with pre-tax dollars. For 2026 the contribution limit is $3,400.8FSAFEDS. Limited Expense Health Care FSA The catch is use-it-or-lose-it: funds generally have to be spent within the plan year, though some employers permit a modest carryover or a grace period of up to two and a half months. If you already know surgery is coming, electing the maximum at open enrollment is a clean way to pay for a large chunk of the procedure with untaxed money.
Limited-Purpose FSA if You Have an HSA
You generally can’t run an HSA and a general-purpose health FSA at the same time. A Limited-Purpose FSA, restricted to dental and vision expenses, is compatible with an HSA. LASIK, contact lenses, eyeglasses, and vision exams all qualify.8FSAFEDS. Limited Expense Health Care FSA Using an LPFSA for the surgery lets your HSA balance keep growing.
No Double-Dipping
Anything you pay for with HSA or FSA dollars can’t also be counted toward the Schedule A medical expense deduction.1Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses Only out-of-pocket costs paid with after-tax money go on Schedule A.
Timing Matters if You’re Chasing the Itemized Deduction
The year you pay is the year you deduct. Not when the surgery is scheduled, not when a bill arrives. Charge the surgery to a credit card in December and it counts on that year’s return, even if you’re still paying off the card next spring.1Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses Checks count on the date mailed or delivered. If you finance through a third-party lender, the full amount is treated as paid when the lender pays the provider, not as you pay off the loan.
The practical move is bunching. If you know another procedure or significant medical expense is coming, scheduling it in the same calendar year as your surgery gives you a real shot at clearing the 7.5% floor. Spread across two years, you may clear it in neither.
Paying for a Spouse or Dependent
You can include medical expenses you paid for your spouse or a dependent in your own deduction. For a spouse, the person must have been your spouse either when the medical service was provided or when you paid for it. For a dependent, the person must have been your qualifying child or qualifying relative at one of those two points.1Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses
A broader rule catches near-dependents. You can deduct expenses for someone who would have been your dependent except that they earned too much, filed a joint return, or could be claimed by someone else. That’s common with college-age children and elderly parents. For children of divorced or separated parents, both parents can include the child’s medical expenses provided the child lived with one or both parents for more than half the year and received more than half their support from the parents.1Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses
Records to Keep if You Claim It
Hold onto an itemized receipt from the surgery center showing the date, the amount paid, and a description of the procedure. Keep the bank or credit card statement confirming payment came from a personal account rather than HSA or FSA funds. Save the explanation of benefits from your insurer showing what was and wasn’t covered. Laser eye surgery itself is rarely questioned on audit; the trouble usually comes from math errors on the 7.5% calculation or from accidentally including costs that insurance reimbursed or that an HSA or FSA already paid.
