The medical expense deduction has two hurdles, and most people who ask about it clear neither. You have to spend more than 7.5% of your adjusted gross income on qualifying medical costs, and your total itemized deductions have to beat your standard deduction.
Step 1: find your 7.5% floor
Only the portion of your qualifying medical expenses that exceeds 7.5% of your adjusted gross income is deductible. The first 7.5% is yours to absorb.
| Your AGI | 7.5% floor | Deductible if you spent $12,000 |
|---|---|---|
| $30,000 | $2,250 | $9,750 |
| $40,000 | $3,000 | $9,000 |
| $50,000 | $3,750 | $8,250 |
| $60,000 | $4,500 | $7,500 |
| $75,000 | $5,625 | $6,375 |
| $100,000 | $7,500 | $4,500 |
| $125,000 | $9,375 | $2,625 |
| $150,000 | $11,250 | $750 |
| $160,000 | $12,000 | $0 |
For any figure not on the table: your AGI × 0.075 is the floor, and medical expenses minus the floor is your deduction.
The same spending produces wildly different results depending on income. This deduction overwhelmingly benefits people with high costs relative to their income — which is, arguably, the point.
Step 2: check whether itemizing beats the standard deduction
Clearing the 7.5% floor gets you a number. It only helps if your total itemized deductions exceed your standard deduction.
Add up: deductible medical expenses + mortgage interest + state and local taxes (up to the cap) + charitable contributions. Compare the total to the standard deduction for your filing status. Whichever is larger is what you take.
Worked example — deduction works
Married couple, AGI $80,000, medical expenses of $18,000 after a major surgery. Mortgage interest $9,000, property and state taxes $8,000, charitable gifts $1,500.
| 7.5% floor | $6,000 |
| Deductible medical ($18,000 − $6,000) | $12,000 |
| Other itemized deductions | $18,500 |
| Total itemized | $30,500 |
That comfortably exceeds the married-filing-jointly standard deduction, so itemizing wins and the medical expenses do real work.
Worked example — deduction does not work
Same couple, same $80,000 AGI, but medical expenses of $8,000 and no mortgage.
| 7.5% floor | $6,000 |
| Deductible medical ($8,000 − $6,000) | $2,000 |
| Other itemized deductions | $8,000 |
| Total itemized | $10,000 |
Well below the standard deduction. They take the standard deduction, and the $8,000 of medical spending produces no tax benefit at all.
This second outcome is far more common than the first, and it is why the medical deduction has a reputation for disappointing people.
What counts
Qualifying expenses are broader than most people assume:
- Doctor, dentist, and specialist fees
- Hospital and surgical costs
- Prescription medications and insulin
- Health insurance premiums paid with after-tax dollars, including Medicare Parts B and D
- Long-term care insurance premiums, subject to age-based limits
- Prescription eyeglasses, contact lenses, and eye exams
- Hearing aids and batteries
- Dental treatment, including braces
- Mental health treatment and therapy
- Addiction treatment programs
- Medical equipment, crutches, wheelchairs
- Home modifications for medical necessity, to the extent they do not add to the property’s value
- Travel for medical care, including mileage at the medical rate, plus lodging within limits
What does not count
- Cosmetic procedures without a medical purpose
- Over-the-counter medications without a prescription
- Vitamins and supplements for general health
- Gym memberships for general fitness
- Health insurance premiums paid pre-tax through an employer — already excluded from your income
- Anything reimbursed by insurance, an HSA, or an FSA
That last one matters. You deduct what you paid out of pocket. Paying with HSA funds and then deducting the same expense is double-dipping.
The bunching strategy
Because the floor resets every year, spreading medical costs across two years can mean clearing it in neither.
If you have elective procedures with timing flexibility — dental work, planned surgery, new glasses — concentrating them into one calendar year can push you over the threshold once instead of falling short twice.
The same logic applies to your other itemized deductions. Bunching charitable contributions into the same year you have high medical costs can be what carries you past the standard deduction.
Whose expenses you can include
Your own, your spouse’s, and your dependents’. You can also generally include expenses for someone who would qualify as your dependent except for failing the income or joint-return test — which lets many people include costs paid for an elderly parent they support.
The expense counts in the year you paid it, not the year the service was provided. A December procedure paid in January is a January-year expense.
Frequently asked questions
Can I deduct medical expenses if I take the standard deduction?
No. Medical expenses are an itemized deduction.
Are Medicare premiums deductible?
Parts B, C, and D generally are. Part A generally is not, if you get it premium-free through payroll taxes.
What about medical expenses paid with a credit card?
Deductible in the year you charged it, not the year you paid the card off.
Does the medical mileage rate differ from business mileage?
Yes, and it is much lower — 20.5¢ per mile through June 30, 2026 and 23.5¢ from July 1, versus 72.5¢ and 76¢ for business.
Is there a better option than the deduction?
Often yes. An HSA gives you a deduction with no 7.5% floor and no need to itemize. If you are eligible for one, it is generally the stronger tool.
The bottom line
Two hurdles: spend more than 7.5% of AGI, and have total itemized deductions that beat your standard deduction. Most people clear neither.
If you have a high-cost year — a major procedure, a long illness, sustained care for a dependent — run the numbers. That is when it becomes substantial.
