The medical expense deduction lets you write off qualified healthcare costs that exceed 7.5% of your adjusted gross income (AGI). For most people this threshold is hard to clear, but in years with major medical events — surgery, serious illness, or expensive ongoing care — it can reduce your federal tax bill meaningfully.

The 7.5% AGI Threshold

You can only deduct medical expenses above 7.5% of your AGI. The IRS does not let you deduct the first 7.5% — it functions like a floor.

2026 Deduction Threshold by Income

AGI 7.5% Floor Medical Expenses to Deduct All Above Floor
$40,000 $3,000 Any amount over $3,000
$60,000 $4,500 Any amount over $4,500
$80,000 $6,000 Any amount over $6,000
$100,000 $7,500 Any amount over $7,500
$150,000 $11,250 Any amount over $11,250
$200,000 $15,000 Any amount over $15,000

Key point: Higher incomes make the deduction harder to reach. Someone earning $200,000 must spend more than $15,000 out of pocket before claiming a single dollar.

What Qualifies as a Deductible Medical Expense

Qualifying Expenses

Category Examples
Insurance premiums Health, dental, vision, long-term care (limits apply), COBRA
Doctor and hospital care Office visits, hospital stays, surgery, lab tests
Mental health Psychiatrist, psychologist, therapist
Prescriptions Prescription drugs, insulin
Vision and hearing Eyeglasses, contacts, laser eye surgery, hearing aids
Dental Preventive, fillings, orthodontics, dentures
Medical equipment Wheelchair, crutches, CPAP, blood pressure monitor
Transportation Miles driven to appointments (21¢/mile in 2026), parking, bus/taxi
Addiction treatment Inpatient rehab, smoking cessation programs (prescribed)
Fertility and pregnancy IVF, prenatal care, childbirth

Non-Qualifying Expenses

Category Why It Doesn’t Qualify
Over-the-counter medications (non-prescribed) Not a prescribed treatment
Vitamins and supplements General health, not disease treatment
Cosmetic procedures Elective unless correcting a deformity from accident/disease
Gym memberships General health, not specifically prescribed for disease
Toothpaste, toiletries Personal care
Non-prescription weight loss programs Unless specifically treating obesity per physician
Funeral expenses Not a medical expense

Worked Example: Family With High Medical Bills

The Carter family files jointly with a combined AGI of $90,000. In 2026 they paid:

  • Health insurance premiums (not employer-covered): $8,400/year
  • Surgery co-pays and bills not covered by insurance: $4,200
  • Prescription costs: $1,800
  • Orthodontics for two children: $3,600
  • Total qualified medical expenses: $18,000

AGI threshold: $90,000 × 7.5% = $6,750
Deductible amount: $18,000 − $6,750 = $11,250

At a 22% federal marginal rate, this deduction saves approximately $2,475 in federal taxes — but only if they itemize and their total itemized deductions exceed the $30,000 standard deduction for MFJ.

Their total itemized deductions: $11,250 (medical) + $10,000 (SALT cap) + $14,000 (mortgage interest) = $35,250. Since $35,250 > $30,000, itemizing saves them more than the standard deduction.

Long-Term Care Insurance Premiums

Long-term care (LTC) insurance premiums are deductible as medical expenses, but the IRS limits the deductible amount by age:

2026 LTC Premium Deduction Limits

Age at End of Tax Year Maximum Deductible Premium
40 or younger $470
41–50 $880
51–60 $1,760
61–70 $4,710
71 or older $5,880

These limits apply per person. A married couple can each deduct up to their age-based limit.

Health Insurance Premiums: Two Situations

If you buy your own insurance (marketplace, COBRA, or non-group): You can include these premiums in your Schedule A medical deductions.

If your employer pays part or all: Only the portion you pay with after-tax dollars is deductible. Premiums deducted pre-tax from your paycheck (through a Section 125 cafeteria plan) are already tax-free and cannot be deducted again.

If you’re self-employed: You likely qualify for the self-employed health insurance deduction (an above-the-line deduction you can take without itemizing). This is more valuable than the Schedule A deduction because it reduces your AGI directly. You generally cannot claim both for the same premiums.

How to Claim the Deduction

  1. Add up all qualifying medical expenses paid for yourself, spouse, and dependents during the year
  2. Subtract any reimbursements from insurance, HSA, or FSA
  3. Calculate your 7.5% floor (AGI × 0.075)
  4. Subtract the floor from your net medical costs
  5. Enter the result on Schedule A, Line 1–4
  6. Compare total itemized deductions to your standard deduction — claim whichever is larger

Keep records: Save Explanation of Benefits (EOB) statements, receipts, prescription records, and mileage logs throughout the year. The IRS can request documentation.

Timing Strategy: Bunch Medical Expenses

If you’re close to clearing the 7.5% threshold in a given year, consider bunching — scheduling elective procedures or filling prescriptions in that same tax year to push more expenses above the floor. In years when you expect to itemize anyway, this maximizes the deduction.

Medical expenses are deductible on Schedule A only above the 7.5% AGI floor — lowering your adjusted gross income (AGI) through retirement contributions or HSA deposits can make more of your medical expenses deductible. If you’re deciding between itemizing and the standard deduction, see itemized vs. standard deduction to determine which saves more in your situation.
