What Is IRS Publication 502?
IRS Publication 502, Medical and Dental Expenses, explains the itemized deduction for unreimbursed medical and dental costs on Schedule A (Form 1040). Updated annually, the 2024 edition (for tax year 2024 returns) is the most current as of early 2026, with a 2025 draft confirming minimal changes.
Key highlights:
- Covers: What counts as a medical expense, whose expenses qualify, reimbursements, and reporting.
- Applies to: Taxpayers who itemize deductions (instead of taking the standard deduction).
- Download it free: IRS Publication 502 PDF.
This isn’t just a list—it’s a detailed rulebook to avoid audits and claim every penny you’re entitled to.
Who Can Claim the Medical Expense Deduction?
Not everyone qualifies, but if you meet these criteria, you’re in:
- You, your spouse, or dependents: Include costs for yourself, your spouse (at the time of service/payment), qualifying children, or relatives.
- Dependents defined: Under age 19 (or 24 if a full-time student), living with you over half the year, and not self-supporting. Special rules for divorced parents, adopted kids, and multiple support agreements.
- Decedents: Expenses paid by you for a deceased spouse or dependent count if they qualified at the time.
- Age limits: No upper age limit, but children under 27 (at year-end) can be included for self-employed health premiums.
Pro Tip: Even if someone isn’t your dependent for exemption purposes, their medical costs may still qualify if they meet the support test.
The 7.5% AGI Rule: How Much Can You Actually Deduct?
Here’s the big one: You can only deduct medical expenses exceeding 7.5% of your adjusted gross income (AGI).
Quick Calculation Example
| Your AGI | 7.5% Threshold | $15,000 in Qualified Expenses | Deductible Amount |
|---|---|---|---|
| $80,000 | $6,000 | $15,000 | $9,000 |
| $100,000 | $7,500 | $12,000 | $4,500 |
| $200,000 | $15,000 | $20,000 | $5,000 |
How to figure it:
- Total all qualified, unreimbursed expenses.
- Subtract 7.5% of AGI.
- Report the excess on Schedule A, Line 1.
This floor has been 7.5% since 2019—permanently extended in recent tax laws.

Expenses That Do NOT Qualify
Avoid these common pitfalls:
- Cosmetic procedures: Face lifts, hair transplants, teeth whitening (unless reconstructive).
- General health items: Vitamins, gym memberships, weight-loss for appearance.
- Nonprescription drugs: Aspirin, cold medicine (except insulin).
- Household help: Babysitting for healthy kids.
- Illegal substances: Marijuana (federally).
- Future care: Advance payments (except lifetime care fees).
Reimbursements: Subtract insurance payouts, HSAs, or FSAs first.
Special Rules: Transportation, Lodging, and More
- Transportation: 21 cents per mile (2024 rate) for medical trips + parking/tolls. Includes ambulances, planes, and accompaniment for kids/elderly.
- Lodging: Up to $50/night per person (essential to care, no meals/vacation element).
- Capital Improvements: Home modifications (ramps, widened doors) minus any home value increase. Use Worksheet A.
- Long-Term Care: Qualified services for chronically ill; premiums limited by age (e.g., $5,880 for 61–70).
Self-Employed Health Insurance Deduction
Self-employed? Deduct 100% of premiums (medical, dental, vision, long-term care) as an above-the-line adjustment on Form 1040—not subject to the 7.5% floor.
- Eligibility: Net profit from business; covers self, spouse, dependents, kids under 27.
- Limits: Up to your earned income; no employer plan eligibility.
Example: A sole proprietor pays $8,000 in family premiums—deduct it fully if net profit allows.
How to Claim It on Your Tax Return
- Gather Receipts: Keep records of payments (don’t attach to return).
- Total Expenses: Use Publication 502 worksheets for reimbursements/capital costs.
- Fill Schedule A: Line 1 for medical expenses.
- E-File: TurboTax, H&R Block, or IRS Free File all support it.
- Amended Returns: Use Form 1040-X for prior years.
Impairment-Related Work Expenses: Deduct as business costs (Form 2106) if disabled and work-related—bypasses the 7.5% rule.
Tips to Maximize Your Medical Expense Deduction in 2025
- Bunch Expenses: Pay in December for big deductions.
- Track Mileage: Use apps like MileIQ for medical drives.
- HSA/FSA Sync: Use tax-free accounts first, then deduct leftovers.

What’s New for 2025–2026?
- Mileage Rate: Still 21 cents/mile (no change from 2024).
- AGI Threshold: Locked at 7.5% (extended indefinitely).
- No Major Overhauls: Draft Publication 502 (2025) mirrors 2024, per IRS.gov. Check IRS.gov/Pub502 for updates.
