The 7.5% AGI Threshold
For most taxpayers, medical expenses are only deductible to the extent they exceed 7.5% of your adjusted gross income. If your AGI is $100,000, your threshold is $7,500. If you spent $10,000 on medical expenses, you can deduct $2,500. This high threshold means most people with moderate medical costs get no deduction. It mainly benefits those with significant medical events — surgery, chronic conditions, dental work, or long-term care.What Counts as a Medical Expense
The IRS defines medical expenses broadly: doctor visits, hospital stays, surgery, dental work, vision care, prescription drugs, mental health treatment, physical therapy, medical equipment (wheelchairs, hearing aids), long-term care, and even some home modifications for medical reasons (ramps, widened doorways). Travel to medical appointments is also deductible (gas or mileage, parking, tolls, bus/taxi fare). Cosmetic surgery generally does not qualify unless medically necessary.Example: Itemizing Medical Expenses
AGI: $75,000. Threshold: $75,000 x 7.5% = $5,625. Your medical expenses: Insurance premiums $6,000, dental crown $2,500, prescriptions $1,200, doctor visits $800 = $10,500 total. Deductible amount: $10,500 - $5,625 = $4,875. At the 22% bracket, that's $1,073 in tax savings. But remember: this only helps if your total itemized deductions exceed the standard deduction ($15,000 single / $30,000 married).
Self-Employed Health Insurance Deduction
Self-employed individuals can deduct 100% of health, dental, and long-term care insurance premiums for themselves, their spouse, and dependents — as an above-the-line deduction on Schedule 1. This is separate from the 7.5% itemized deduction and much more valuable. The deduction can't exceed your net self-employment income. You can't take this deduction for months you were eligible for employer-sponsored coverage.

HSA: The Triple Tax Advantage
If you have a high-deductible health plan, a Health Savings Account (HSA) offers: tax-deductible contributions ($4,150 individual / $8,300 family for 2025), tax-free growth, and tax-free withdrawals for qualified medical expenses. HSA contributions are above-the-line deductions. You can invest HSA funds and let them grow — many financial advisors consider HSAs the most tax-advantaged account available.Track Medical Expenses Year-Round
