Claim Medical Expense Tax Deduction – If you had significant out-of-pocket healthcare costs in 2025, you may be able to claim a medical expense tax deduction on your 2025 federal tax return (filed in 2026). The IRS allows this itemized deduction for qualified unreimbursed medical and dental expenses that exceed 7.5% of your adjusted gross income (AGI). Understanding the rules can help you save money, but you must itemize deductions on Schedule A to benefit.
This guide explains everything U.S. taxpayers need to know about claiming medical expense tax deductions, based on the latest IRS guidelines in Publication 502 (2025).
What Is the Medical Expense Tax Deduction?
The medical expense tax deduction lets you reduce your taxable income by deducting certain unreimbursed medical and dental costs. You can only deduct the portion of your total qualified expenses that exceeds 7.5% of your AGI.
For example, if your 2025 AGI is $80,000 and you had $12,000 in qualified medical expenses, you can deduct $6,000 ($12,000 – $6,000 = $6,000, where $6,000 is 7.5% of $80,000).
This deduction applies only if you itemize on Schedule A (Form 1040) and your total itemized deductions exceed the standard deduction for your filing status.
Who Can Claim Medical Expense Deductions?
You can claim medical expenses paid for:
- Yourself
- Your spouse
- Your dependents (including qualifying children or relatives who meet IRS tests)
The person must have been your spouse or dependent at the time the services were provided or when you paid the expenses. This includes adopted children living with you and, in some cases, children of divorced or separated parents.
You cannot claim expenses reimbursed by insurance, HSAs, FSAs, or other sources.
The 7.5% AGI Threshold: How Much Can You Deduct?
The IRS sets a floor of 7.5% of your AGI. Only expenses above this amount qualify for the deduction. This threshold has been in place for recent years and remains for tax year 2025.
2025 Standard Deduction Amounts (for comparison):
- Single or Married Filing Separately: $15,750
- Married Filing Jointly or Qualifying Surviving Spouse: $31,500
- Head of Household: $23,625
Additional amounts apply for those age 65+ or blind. Itemize only if your total deductions (including medical) exceed these amounts.
Qualified Medical Expenses: What Counts for the Deduction?
Qualified medical expenses include costs for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for affecting any part or function of the body. Here are common examples from IRS Publication 502 (2025):
Includible Medical Expenses (Partial List)
- Doctor, dentist, surgeon, chiropractor, psychiatrist, and psychologist fees
- Hospital and nursing home care (if primarily for medical care)
- Prescription drugs and insulin
- Eyeglasses, contact lenses, and vision correction surgery (e.g., LASIK)
- Hearing aids and batteries
- Dental care (cleanings, fillings, braces, dentures)
- Ambulance services and transportation to medical care
- Breast pumps and supplies
- Acupuncture and certain alternative treatments
- Service animals (guide dogs, etc., including food and vet care)
- Long-term care services (for chronically ill individuals) and limited long-term care insurance premiums
- Weight-loss programs prescribed for a specific disease (e.g., obesity)
- Home modifications for medical needs (e.g., ramps, widened doorways—minus any increase in home value)
- Medical conferences related to your condition (admission and transportation only)
For the full alphabetical list and details, refer to IRS Publication 502.
Non-Deductible Expenses: What Does NOT Qualify?
Not every health-related cost counts. The IRS excludes expenses that are primarily for general health or cosmetic purposes.
Common Non-Qualifying Expenses
- Cosmetic procedures (e.g., facelifts, hair transplants, electrolysis—unless medically necessary to correct a deformity)
- Over-the-counter medicines (except insulin)
- Vitamins, supplements, and health club dues
- Maternity clothes or diaper services
- Funeral expenses
- Future medical care payments (except certain advance lifetime care fees)
- Non-prescribed weight-loss programs or diet foods
- Household help (unless it qualifies as nursing services)
- Illegal substances or treatments
Always check the primary purpose of the expense—it must alleviate or prevent a specific physical or mental condition.
Step-by-Step: How to Claim Medical Expense Tax Deduction on Your 2025 Return?
- Gather Records — Collect receipts, bills, Explanation of Benefits (EOBs), and proof of payment for all medical expenses paid in 2025.
- Calculate Total Qualified Expenses — Add up only unreimbursed, qualified costs.
- Apply the 7.5% Floor — Subtract 7.5% of your AGI from the total.
- Complete Schedule A — Enter the excess amount on Line 1 of Schedule A (Medical and Dental Expenses).
- Compare to Standard Deduction — If your total itemized deductions (medical + state taxes + mortgage interest + charity, etc.) exceed the standard deduction, itemize on Form 1040.
- File Your Return — Use tax software, a professional, or paper forms by the 2026 deadline (typically April 15, or October 15 with extension).
Use IRS Worksheet in Publication 502 if needed for complex situations like capital expenses.
Recordkeeping Requirements
Keep detailed records for at least three years in case of an audit:
- Name and address of each provider
- Date and amount of each payment
- Description of the service or item
- Receipts, canceled checks, or credit card statements
- Insurance reimbursements or EOBs
Do not send records with your return—retain them.
Tips to Maximize Your Medical Expense Tax Deduction
- Bunch Expenses — Pay additional qualified costs in December 2025 if it helps you exceed the 7.5% floor.
- Track Transportation — Include mileage (21 cents per mile in 2025) plus parking and tolls.
- Coordinate with HSAs/FSAs — Use pre-tax accounts first, then deduct remaining out-of-pocket costs.
- Consider Long-Term Care — Qualified long-term care premiums have age-based limits that can add up.
- Review State Rules — Some states allow medical deductions with different thresholds or rules.
Consult a tax professional or use reliable tax software to run scenarios.
Common Mistakes to Avoid
- Claiming reimbursed expenses
- Including cosmetic or general health costs
