What Is a Qualified Medical Expense for Taxes?

A qualified medical expense for taxes is any cost you pay to diagnose, treat, prevent, or mitigate a physical or mental condition for yourself, your spouse, or a dependent.¹ That definition matters in two different ways. You can pay for these costs tax-free from a health savings account or flexible spending account, or you can deduct them on Schedule A if you itemize. The rules overlap, but they are not identical, and the differences catch people every filing season.

Why Most People Won’t Deduct Medical Expenses on Schedule A

The itemized deduction has a steep floor. You can only deduct the portion of your qualifying medical expenses that exceeds 7.5% of your adjusted gross income.¹ At an AGI of $80,000, that means the first $6,000 of medical bills produces no deduction at all. At $150,000, the threshold is $11,250.

Even clearing the floor is not enough. Itemizing only pays off when your total itemized deductions beat the standard deduction. For 2026, the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.² If your medical bills, state taxes, mortgage interest, and charitable contributions together don’t beat that number, the standard deduction wins. For most households with routine medical spending, health accounts are the more useful tool.

HSAs and FSAs: The Practical Path

Health savings accounts and flexible spending accounts let you pay for qualified medical expenses with pre-tax dollars, and there is no 7.5% floor. Every qualifying dollar avoids income tax. The trade-off is a contribution cap.

For 2026, HSA contributions are limited to $4,400 for self-only coverage and $8,750 for family coverage.³ Health care FSAs cap employee salary reductions at $3,400 for 2026.

To contribute to an HSA, you generally need a high-deductible health plan with a deductible of at least $1,700 for self-only or $3,400 for family coverage, and an out-of-pocket maximum no higher than $8,500 or $17,000, respectively.⁴ Starting January 1, 2026, bronze and catastrophic plans purchased through a marketplace exchange or directly are treated as HSA-compatible regardless of the standard HDHP definition. The same legislation lets people in direct primary care arrangements contribute to an HSA and pay periodic DPC fees with HSA funds tax-free.⁵

The Over-the-Counter Split

This is where taxpayers get tripped up more than anywhere else. Since the CARES Act took effect in 2020, HSAs, FSAs, Archer MSAs, and health reimbursement arrangements can reimburse over-the-counter medications and menstrual care products without a prescription.⁶

On Schedule A, the older rule still applies. Except for insulin, you cannot deduct a drug unless a doctor prescribed it.¹ So a bottle of ibuprofen is reimbursable from your FSA but not deductible on your taxes. Same product, different tax treatment, depending on how you paid.

What Counts as a Qualified Medical Expense

Professional Services

Fees paid to doctors, dentists, surgeons, chiropractors, psychiatrists, psychologists, and other licensed practitioners qualify when the services treat or prevent a specific condition.¹ Preventive care counts too: annual physicals, dental cleanings, and screening tests all qualify even when nothing is wrong. Acupuncture qualifies, as do fees paid to Christian Science practitioners for medical care. The test is whether the service treats or prevents a condition rather than simply promoting general well-being.

Nursing services qualify when the caregiver performs tasks a nurse would typically handle, such as administering medication, changing dressings, and bathing the patient. The person does not need to hold a nursing license. If the attendant also handles chores like laundry or cooking, you split the cost between medical duties and personal services.¹

Prescriptions and Insulin

Prescription medications and insulin qualify across the board, both on Schedule A and through any health account. The drug must be legally obtained in the United States. Medications imported from other countries generally do not qualify.¹

Insurance Premiums

Health insurance premiums you pay out of pocket for policies covering medical care qualify, including premiums for Medicare Part B and Part D. Premiums paid through a pre-tax arrangement at work, which is the standard employer setup, cannot be deducted again on Schedule A because they were never taxed in the first place.¹

Long-term care insurance premiums qualify only up to age-based dollar limits that the IRS adjusts each year. For 2026, those limits per person range from $500 at age 40 or younger up to $6,200 above age 70. Amounts above those caps do not qualify. HSA funds can pay long-term care premiums within the same limits.

Equipment and Home Modifications

Eyeglasses, hearing aids, wheelchairs, crutches, and artificial limbs qualify in full.⁷ Home modifications like ramps, wider doorways, grab bars, or lowered cabinets can qualify when the primary purpose is accommodating a medical condition. But the deductible amount is the cost of the improvement minus any increase in your home’s value. Spend $10,000 on a medically necessary elevator that raises your home’s market value by $4,000, and you deduct $6,000. If the improvement adds no value, or reduces it, the full cost qualifies.

Service Animals

The costs of buying, training, and maintaining a guide dog or other service animal qualify when the animal assists someone with a visual, hearing, or other physical disability. Food, grooming, and veterinary care count as part of maintaining the animal.¹

Travel and Lodging

Transportation to and from medical care qualifies. Bus, taxi, train, plane, and ambulance charges all count.¹ If you drive, you can either track actual costs like gas and oil or use the IRS standard medical mileage rate. For 2026, that rate is 20.5 cents per mile.⁸ Parking and tolls count on top of either method. Depreciation, insurance, and general car maintenance do not.

Lodging qualifies when overnight travel is required for medical care, but the deduction is capped at $50 per night per person. A parent traveling with a sick child can claim up to $100 per night for the two of them. The stay cannot include any vacation element, and meals during medical travel are not included.

What Doesn’t Qualify

The IRS draws a hard line between treating a medical condition and maintaining general health. Several common categories are excluded:

Vitamins and supplements, unless prescribed to treat a specific diagnosed condition. A daily multivitamin for general health does not qualify.¹
Gym memberships and health club dues, treated as personal expenses even when exercise improves your health.
Toothbrushes, toothpaste, mouthwash, and similar personal-care items.
Cosmetic surgery or treatments aimed at improving appearance, unless they correct a deformity from a congenital abnormality, an accident, or a disfiguring disease.

Weight-loss programs fall into a narrow zone. They qualify only when they treat a specific disease diagnosed by a physician, such as obesity, diabetes, hypertension, or heart disease. Joining a program to look better or feel healthier does not count.⁹ Special food or beverages can qualify only when the food does not satisfy normal nutritional needs, it treats an illness, and a physician substantiates the need. Even then, only the amount the special food costs above ordinary food is deductible. Organic groceries or trendy diets do not meet the test.

Records You Need to Keep

A deduction is only as good as the paperwork behind it. For every medical expense, keep a receipt or invoice showing the provider’s name, the date of service, a description of what was provided, and the amount you paid. Credit card and bank statements can supplement receipts but usually lack the detail the IRS wants.

For items that straddle medical and personal use, ask your doctor for a Letter of Medical Necessity. It is a signed statement explaining that a specific product or service is required to treat a diagnosed condition. Ergonomic chairs, air purifiers, and mattresses fall into this zone. Without the letter, expect a denial.

Hold onto medical records for at least three years from the date you file the return or two years from the date you paid the tax, whichever is later.¹⁰ If you never file a return, the statute of limitations never starts running, and the IRS recommends keeping those records indefinitely.
