Medical Equipment Tax Deduction: AGI Floor, HSAs, and Schedule A

A medical equipment tax deduction is available for items you buy to diagnose, treat, or manage a health condition, but only the portion of your total medical spending that exceeds 7.5% of your adjusted gross income actually reduces your tax bill.¹ The deduction lives on Schedule A, so it only helps if your combined itemized deductions beat the standard deduction for your filing status. Wheelchairs, hearing aids, blood glucose monitors, oxygen equipment, prosthetics, and prescription eyewear all qualify, and so do the batteries, repairs, and upkeep that keep them working.

What Equipment Qualifies

IRS Publication 502 spells out the categories. The common thread across every item is that its primary purpose has to be medical care, not general comfort or wellness.²

Mobility aids: wheelchairs, crutches, and walkers used for the relief of a sickness or disability.
Breathing equipment: oxygen tanks and oxygen delivery systems for breathing problems caused by a medical condition.
Hearing aids, including batteries, repairs, and maintenance.
Diagnostic devices: blood sugar test kits, blood pressure monitors, and similar tools used to diagnose and manage illness.
Prescription eyeglasses and contact lenses needed for medical reasons.
Prosthetics, including artificial limbs and artificial teeth.
Special telephone equipment (TTY and TDD) for a person who is deaf, hard of hearing, or has a speech disability.
A wig purchased on the advice of a physician for a patient who has lost all hair from disease.

Over-the-counter medical devices count too. A thermometer or blood pressure cuff bought without a prescription is deductible as long as you’re using it to diagnose or treat illness.²

Maintenance, Batteries, and Repairs

Operation and upkeep costs for qualifying equipment are deductible as long as the main reason for them is medical care. Wheelchair maintenance, hearing aid batteries, and repairs to special telephone equipment all qualify, even in cases where only part of the original equipment purchase itself was deductible.²

Items Bought in a Special Form

Sometimes an ordinary consumer product has to be purchased in a modified form to accommodate a disability. In that case, only the difference between the special-form version and the regular version is deductible. The IRS uses Braille books as its example: the deductible amount is what you paid above the cost of a standard printed edition, not the full price.²

The 7.5% AGI Floor and When Itemizing Pays Off

The 7.5% threshold works as a floor, not a cap. If your AGI is $60,000, the first $4,500 of medical spending produces no deduction. Spend $7,000, and only $2,500 is deductible.¹

Clearing that floor still isn’t enough on its own. Your total itemized deductions across all categories, including state and local taxes, mortgage interest, and charitable gifts, have to exceed the standard deduction for your filing status. For tax year 2026, the standard deduction amounts are:³

Single filers: $16,100
Married filing jointly: $32,200
Head of household: $24,150
Married filing separately: $16,100

Take a single filer with an AGI of $80,000. The 7.5% floor absorbs the first $6,000 of medical spending. If qualifying expenses total $10,000, only $4,000 clears the floor, and unless there’s at least $12,100 in other itemized deductions to push the total past $16,100, the standard deduction still wins. This is why the deduction tends to pay off in years with a big equipment purchase, like a powered wheelchair or a home elevator. Concentrating large costs into a single tax year makes it far more likely both hurdles get cleared.

Vehicle Modifications

Adaptive equipment installed in a vehicle for a person with a disability is deductible at its full installation cost. Hand controls and wheelchair lifts are the standard examples. If you have to buy a vehicle specially designed to hold a wheelchair rather than a standard car, you can deduct the difference in cost between the two.²

What you can’t deduct is the vehicle itself. Depreciation, insurance, and general repairs are treated as personal transportation costs. Only the adaptive equipment and its upkeep qualify. Driving to medical appointments is a separate category, deductible at actual gas and oil costs or at the IRS standard medical mileage rate of 20.5 cents per mile for 2026.⁴

Home Modifications

Structural changes to your home can qualify as medical expenses when they’re made for a disabled person’s medical care. The common examples are wheelchair ramps, widened doorways and hallways, bathroom grab bars, lowered kitchen cabinets, stairway modifications, and porch lifts.²

How much you can deduct depends on whether the modification raises your property value. If a bathroom grab bar adds nothing to market value, the full cost is deductible. If a home elevator costs $10,000 and increases property value by $6,000, only the $4,000 difference qualifies. Larger projects may require a professional appraisal to establish before-and-after values.

Certain accessibility modifications that accommodate a disabled condition are generally treated as not increasing property value, and the IRS lists ramps, widened doorways, support bars, and modified warning systems in that category, so those are typically deductible in full. Only reasonable costs count; extra spending driven by architectural or aesthetic preferences is excluded.²

What Doesn’t Qualify

Items that are merely beneficial to general health are out. Vitamins and supplements taken without a physician’s direction for a diagnosed condition don’t qualify. Gym memberships are disallowed unless the membership was purchased solely to treat a specific disease diagnosed by a physician, such as obesity, hypertension, or heart disease.⁵ A massage chair bought because it feels good on your back doesn’t qualify even if a doctor mentions it might help, because its primary purpose isn’t treating a specific condition.

Cosmetic procedures are generally out too, since they’re aimed at improving appearance rather than treating a condition. The exception is cosmetic surgery that corrects a deformity from a congenital abnormality, an accidental injury, or a disfiguring disease. Breast reconstruction after cancer surgery is the IRS’s own example.²

Coordinating With HSAs, FSAs, and HRAs

If you pay for equipment using tax-free funds from a Health Savings Account, Flexible Spending Account, or Health Reimbursement Arrangement, you can’t also claim those costs as an itemized deduction. Amounts reimbursed from an FSA or HRA, and tax-free HSA distributions, have to be subtracted from your medical expenses before applying the 7.5% floor.⁶

For smaller equipment purchases that won’t clear the itemization hurdle anyway, paying through an HSA or FSA usually delivers a better result than trying to deduct on Schedule A, because the tax benefit runs dollar-for-dollar through pre-tax contributions with no AGI floor. Save the itemized deduction route for expenses beyond what your tax-advantaged accounts can cover. Home accessibility modifications may require a letter of medical necessity from your provider before an HSA or FSA administrator will approve reimbursement.

Documentation You Need to Keep

Keep itemized receipts and proof of payment for every purchase. For equipment that isn’t obviously medical, like a home modification or a specialized consumer product, a written statement from your physician documenting the medical necessity strengthens your position. The letter should identify the diagnosis, explain why the specific equipment or modification is needed, and indicate the expected duration of use. Publication 502 requires physician involvement for several categories, including weight-loss programs, special foods, and special education fees.²

Before running the deduction math, subtract every insurance reimbursement and every tax-free HSA, FSA, or HRA distribution from your total. Only your true out-of-pocket cost after all reimbursements counts toward the 7.5% floor.

Claiming the Deduction on Schedule A

Medical equipment deductions go on Schedule A (Form 1040). Line 1 is your total medical and dental expenses after reimbursements. Line 2 pulls in your AGI. Line 3 calculates 7.5% of that AGI. Line 4 is the deductible portion, which is Line 1 minus Line 3.⁷ That figure feeds your total itemized deductions, which then gets compared to the standard deduction.

Don’t mail receipts or physician letters with the return; keep them in your own files. You need to hold on to supporting documentation for at least three years from the date you filed the return or two years from the date you paid the tax, whichever is later.⁸ If the IRS audits during that window and you can’t produce receipts or a physician’s letter for what you deducted, the deduction gets disallowed and you’ll owe back taxes plus interest.
