Medical expenses can be a significant financial burden, but the tax code provides relief through the medical expense deduction. This itemized deduction allows you to deduct unreimbursed medical and dental expenses that exceed a percentage of your adjusted gross income (AGI). Understanding which expenses qualify, how the threshold works, and strategies for maximizing the deduction can result in meaningful tax savings, particularly for taxpayers with high medical costs.
How the Medical Expense Deduction Works
The AGI Threshold
You can deduct unreimbursed medical and dental expenses that exceed ~7.5% of your adjusted gross income. Only the amount above this threshold is deductible.
| AGI | Threshold (~7.5%) | Medical Expenses | Deductible Amount |
|---|---|---|---|
| ~$50,000 | ~$3,750 | ~$6,000 | ~$2,250 |
| ~$75,000 | ~$5,625 | ~$8,000 | ~$2,375 |
| ~$100,000 | ~$7,500 | ~$12,000 | ~$4,500 |
| ~$150,000 | ~$11,250 | ~$15,000 | ~$3,750 |
The ~7.5% threshold was made permanent by the Consolidated Appropriations Act of 2021. Prior to this, the threshold was scheduled to increase to ~10%.
Itemizing Requirement
The medical expense deduction is an itemized deduction claimed on Schedule A. You benefit only if your total itemized deductions exceed the standard deduction:
| Filing Status | 2026 Standard Deduction |
|---|---|
| Single | ~$15,000 |
| Married filing jointly | ~$30,000 |
| Head of household | ~$22,500 |
For many taxpayers, the high standard deduction means that medical expenses alone are not enough to make itemizing worthwhile. However, when combined with mortgage interest, state taxes, and charitable contributions, the total may exceed the standard deduction.
Qualifying Medical Expenses
Expenses That Qualify
The IRS defines qualifying medical expenses broadly as costs for the diagnosis, cure, mitigation, treatment, or prevention of disease:
| Category | Examples |
|---|---|
| Doctor and specialist visits | Physician fees, specialist consultations, lab tests |
| Hospital and surgical costs | Inpatient care, outpatient surgery, emergency room visits |
| Dental care | Cleanings, fillings, crowns, orthodontics, dentures |
| Vision care | Eye exams, glasses, contact lenses, LASIK surgery |
| Prescription medications | All prescribed drugs (not over-the-counter unless prescribed) |
| Mental health | Therapy, psychiatric care, substance abuse treatment |
| Long-term care | Nursing home, assisted living (if primarily for medical care), in-home nursing |
| Medical equipment | Wheelchairs, hearing aids, prosthetics, blood sugar monitors |
| Travel for medical care | Mileage at ~$0.22/mile, parking, tolls, airfare for treatment unavailable locally |
| Health insurance premiums | Premiums paid with after-tax dollars (not pre-tax payroll deductions) |
Expenses That Do Not Qualify
| Non-Qualifying Expense | Reason |
|---|---|
| Cosmetic surgery (unless medically necessary) | Not for treatment of disease |
| Gym memberships (general fitness) | Not specific medical treatment |
| Over-the-counter medications (unless prescribed) | Not prescribed drugs |
| Health insurance premiums paid pre-tax | Already excluded from income |
| Funeral and burial expenses | Not medical care |
| Teeth whitening | Cosmetic, not medical |
| Nutritional supplements (general) | Not prescribed for specific condition |
Comparison: Medical Deduction vs. HSA vs. FSA
| Feature | Medical Deduction | HSA | FSA |
|---|---|---|---|
| Eligibility | Any itemizer | HDHP enrollees | Employer-offered |
| Tax benefit timing | Year-end | Contribution time | Contribution time |
| AGI threshold | ~7.5% | None | None |
| Annual limit | No cap (above threshold) | ~$4,300 (self), ~$8,550 (family) | ~$3,300 |
| Carries forward | No | Yes (indefinitely) | Limited (~$640 rollover) |
| Reduces payroll tax | No | Yes (if payroll deducted) | Yes |
Tips for Maximizing Your Medical Expense Deduction
-
Bunch medical expenses into one year. If you have elective procedures or dental work, schedule them in a year when you already have high medical costs. Concentrating expenses in one year helps you exceed the ~7.5% AGI threshold and makes itemizing more beneficial.
-
Track every expense. Keep receipts, explanation of benefits (EOBs), and records for all medical expenses throughout the year. Small expenses like copays, prescription costs, and medical mileage add up quickly.
-
Include travel costs. Medical mileage at ~$0.22 per mile, plus parking and tolls, is deductible. If you travel for specialized treatment, airfare, hotel, and meals during treatment may also qualify. Document all trips with dates, destinations, and medical purposes.
-
Count long-term care premiums. Age-based portions of long-term care insurance premiums are deductible as medical expenses. For taxpayers age ~71 and older, up to ~$5,960 per person can be included.
-
Deduct health insurance premiums. If you pay health insurance premiums with after-tax dollars (such as individual marketplace plans or COBRA coverage), include these in your medical expense total. Premiums paid through pre-tax payroll deductions are already excluded from income and cannot be double-counted. See our self-employment tax guide for the self-employed health insurance deduction, which is claimed differently.
-
Coordinate with HSA withdrawals. If you have an HSA, you can choose to pay medical expenses out of pocket and let your HSA grow tax-free. Then claim the medical expense deduction for out-of-pocket costs that exceed the ~7.5% threshold. The HSA balance continues to grow for future use.
-
Lower your AGI to lower the threshold. Strategies that reduce your AGI, such as maximizing retirement contributions, also lower the ~7.5% threshold, making more of your medical expenses deductible. See our federal income tax guide for AGI reduction strategies.
Key Takeaways
- The medical expense deduction allows you to deduct unreimbursed medical and dental expenses exceeding ~7.5% of your AGI.
- The deduction requires itemizing, which benefits taxpayers only when total itemized deductions exceed the standard deduction (~$15,000 single, ~$30,000 married).
- Qualifying expenses include doctor visits, hospital costs, dental and vision care, prescriptions, medical equipment, and travel for medical care.
- Health insurance premiums paid with after-tax dollars are deductible, but pre-tax premiums cannot be included.
- Bunching elective medical expenses into a single year is the most effective strategy for exceeding the ~7.5% threshold.
- HSAs and FSAs provide complementary benefits that do not require itemizing and should be considered alongside the medical deduction.
