Medical Expense Tax Deduction: What Qualifies and the 7.5% AGI Floor

If you had a year with major surgery, expensive dental work, or ongoing treatment, you may be able to deduct those costs on your tax return. But the IRS sets a high bar: only medical expenses exceeding 7.5% of your AGI are deductible, and you must itemize on Schedule A to claim them.

Key Takeaways

• Only unreimbursed medical expenses that exceed 7.5% of your AGI are deductible.
• You must itemize deductions on Schedule A — if the standard deduction is higher, you get no benefit.
• Qualifying expenses include insurance premiums, dental, vision, prescriptions, and long-term care.
• Cosmetic surgery, gym memberships, and employer-reimbursed costs do NOT qualify.

How the 7.5% AGI Floor Works

The medical expense deduction is not dollar-for-dollar. The IRS only allows you to deduct the amount that exceeds 7.5% of your AGI.

Example: Your AGI is $80,000. Your medical floor is $80,000 x 7.5% = $6,000.

Scenario	Medical Spending	Deductible Amount
Low medical year	$4,000	$0 (below the $6,000 floor)
Moderate year	$8,000	$2,000 ($8,000 − $6,000)
High medical year	$15,000	$9,000 ($15,000 − $6,000)

Even in the “high” scenario, you only benefit if your total itemized deductions (medical + SALT + mortgage interest + charity) exceed the standard deduction. That is a second hurdle to clear.

What Medical Expenses Qualify?

The IRS defines qualifying expenses broadly in Publication 502. Here are the most common:

• Doctors, surgeons, and specialists — office visits, procedures, and hospital stays
• Dental care — cleanings, fillings, crowns, braces, dentures
• Vision care — eye exams, glasses, contacts, LASIK
• Prescription drugs and insulin
• Mental health — therapy, psychiatry, substance abuse treatment
• Health insurance premiums you pay with after-tax dollars (not employer-subsidized premiums deducted from your paycheck pre-tax)
• Long-term care insurance premiums (subject to age-based limits)
• Medical equipment — wheelchairs, hearing aids, crutches
• Transportation for medical care — mileage, parking, tolls, ambulance fees
• Nursing home costs if the primary reason for residence is medical care

What Does NOT Qualify?

• Cosmetic surgery (unless necessary to correct a deformity from disease, injury, or birth defect)
• Gym memberships and health club dues (even if a doctor recommends exercise)
• Over-the-counter vitamins and supplements (unless prescribed)
• Employer-reimbursed expenses or amounts paid by insurance
• Expenses paid with HSA or FSA funds (already tax-advantaged)
• Teeth whitening
• General health improvement programs (diet food, weight-loss programs without a specific diagnosis)

Medical Deductions vs. HSA/FSA

If you have access to a Health Savings Account or Flexible Spending Account, those are usually a better first line of defense against medical costs.

Feature	Medical Deduction (Schedule A)	HSA	FSA
Tax benefit	Deduction (only above 7.5% floor)	Triple tax-free	Pre-tax contributions
Must itemize?	Yes	No	No
AGI floor?	7.5%	None	None
Contribution limit (2025)	N/A	$4,300 (self) / $8,550 (family)	$3,300
Rolls over?	N/A	Yes, indefinitely	Limited ($640 or grace period)

For a deeper comparison, see HSA vs. FSA.

Bottom line: Use your HSA/FSA dollars first. Only rely on the Schedule A medical deduction for large, unreimbursed costs that push you past the 7.5% floor.

Strategy: Bunching Medical Expenses

If you know you will have elective medical expenses (LASIK, orthodontics, joint replacement), consider bunching them into a single tax year where you expect high medical costs. This concentrates spending to clear the 7.5% floor and the standard deduction threshold in one year, rather than spreading costs across two years and deducting nothing in either.

How it works:

1. Schedule elective procedures, dental work, and vision care in the same calendar year.
2. Pre-pay January insurance premiums in December if your plan allows.
3. Stock up on prescription refills before year-end.

This is the same logic behind charitable bunching — control the timing of deductible expenses to maximize their value.

Standard Deduction Comparison

Remember, your total itemized deductions must exceed the standard deduction for the medical expense deduction to help you. Here are the current thresholds:

If you file as Single and your total itemized deductions (including the medical amount above the floor) come to $14,000, you are better off taking the $15,000 standard deduction. The medical expense deduction only matters when it pushes your total itemized deductions past these thresholds.

Self-Employed Health Insurance Deduction

If you are self-employed, there is a better option for health insurance premiums. The self-employed health insurance deduction is an above-the-line deduction on Schedule 1 — meaning you get it regardless of whether you itemize, and there is no 7.5% floor.

This covers premiums for medical, dental, and vision insurance for yourself, your spouse, and your dependents, as long as you are not eligible for an employer-subsidized plan (including a spouse’s employer plan).

You cannot double-dip: premiums claimed as a self-employed health insurance deduction cannot also be included in your Schedule A medical expenses. For more self-employed deductions, see our self-employed tax strategies guide.
