If you’re wondering whether your doctor bills, prescriptions, and hospital visits can actually lower your tax bill — the answer is yes, but only if you know the rules. The IRS allows you to deduct medical expenses that exceed 7.5% of your Adjusted Gross Income (AGI). This guide walks you through the exact calculation — and our free calculator does it in seconds.

What Is the Medical Expense Deduction?
The medical expense deduction is an itemized deduction on Schedule A of your federal tax return. It lets you reduce your taxable income by the amount of qualified medical expenses that exceed the IRS threshold of 7.5% of your AGI. This deduction is available for the 2025 tax year (filed in 2026) and applies to expenses you paid for yourself, your spouse, and your dependents.
Step-by-Step: How to Calculate Your Medical Expense Deduction
Step 1: Find Your Adjusted Gross Income (AGI)
Your AGI is on Line 11 of Form 1040. It’s your gross income minus above-the-line deductions like student loan interest, IRA contributions, and self-employed health insurance. Example: If your gross income is $85,000 and you have $5,000 in above-the-line deductions, your AGI is $80,000.
Step 2: Calculate 7.5% of Your AGI
Multiply your AGI by 0.075 to find the threshold you must exceed before any deduction kicks in. Example: $80,000 AGI × 7.5% = $6,000 threshold.
Step 3: Add Up All Qualified Medical Expenses
Tally every qualifying medical expense you paid out-of-pocket during the tax year. Qualifying expenses include doctor and specialist visits, prescription medications and insulin, dental work (cleanings, fillings, crowns, braces), vision expenses (glasses, contacts, LASIK), hospital and surgical costs, mental health therapy and counseling, medical equipment (wheelchairs, hearing aids, CPAP machines), medical travel at 21 cents per mile, and health insurance premiums if not pre-tax through an employer.
Step 4: Subtract the Threshold from Your Total Expenses
Subtract the 7.5% threshold from your total qualified medical expenses. The remainder is your deductible amount. Example: $9,500 total expenses − $6,000 threshold = $3,500 deduction. That $3,500 reduces your taxable income. If you’re in the 22% tax bracket, that saves you $770 in taxes.
Step 5: Compare to the Standard Deduction
This deduction only helps if you itemize. For 2025, the standard deduction is $15,000 for single filers and $30,000 for married filing jointly. You should itemize only if your total itemized deductions (including medical) exceed your standard deduction amount.

What Medical Expenses Do NOT Qualify?
The IRS is very specific about what counts. Common expenses that are not deductible include over-the-counter medications (unless prescribed), cosmetic surgery (unless medically necessary), gym memberships (unless prescribed by a doctor for a specific condition), teeth whitening, vitamins and supplements (unless prescribed), and premiums paid with pre-tax dollars through an employer.
Real-World Calculation Examples
Example 1: Single Filer, AGI $60,000
Threshold: $60,000 × 7.5% = $4,500. If you paid $6,200 in medical expenses, your deduction is $6,200 − $4,500 = $1,700. At the 22% bracket, you save $374.
Example 2: Married Filing Jointly, AGI $120,000
Threshold: $120,000 × 7.5% = $9,000. If you paid $14,500 in combined medical expenses, your deduction is $14,500 − $9,000 = $5,500. At the 22% bracket, that’s $1,210 in tax savings. Use our Medical Deduction Calculator for Married Filing Jointly to run your numbers.
Example 3: Self-Employed, AGI $75,000
Self-employed individuals have two potential ways to deduct health costs: the self-employed health insurance deduction (above-the-line, on Schedule 1) and the Schedule A medical deduction for out-of-pocket costs. Our Self-Employed Medical Deduction Calculator accounts for both.
Tips to Maximize Your Medical Expense Deduction
Bunch expenses into one year. If you’re close to the threshold, consider scheduling elective procedures, dental work, or purchasing medical equipment in the same tax year to push past the 7.5% line.
Track medical mileage. Every drive to the doctor counts at 21 cents per mile for 2025. A few dozen trips add up fast. Don’t forget lodging: hotel stays for out-of-town medical treatment (up to $50/night per person) are deductible. Include after-tax premiums: if you pay health insurance premiums out-of-pocket (not through an employer plan), they count. Don’t double-count HSA/FSA expenses: expenses reimbursed by an HSA or FSA cannot also be deducted.
