Can I claim a tax deduction for medical expenses I paid on behalf of my parents?

Yes, you may be able to deduct medical expenses you pay for your parents on your federal tax return. However, several requirements must be met, and there's a special rule that allows you to deduct these expenses even if your parent has too much income to be claimed as your dependent.

Basic Requirements

According to IRS Publication 502, you can include medical expenses you pay for your dependent on Schedule A (Form 1040) if you itemize deductions. The person must have been your dependent either at the time the medical services were provided or at the time you paid the expenses.

To qualify as your dependent for the medical expense deduction, your parent must meet both of these requirements:

1. The person was a qualifying relative (defined below)
2. The person was a U.S. citizen or national, or a resident of the United States, Canada, or Mexico

Special Rule for Parents with Income

Here's the key provision that helps many taxpayers: According to the IRS FAQ for Caregivers, you can include medical expenses you paid for an individual who would have been your dependent except that:

• The individual received gross income of $5,200 or more in 2025 ($5,050 for 2024)
• The individual filed a joint return for the year, or
• You (or your spouse if filing jointly) are properly claimed as a dependent on someone else's return

This means even if your parent receives Social Security benefits and has some other income that exceeds the gross income threshold, you may still deduct the medical expenses you pay for them, as long as the other qualifying relative tests are met.

Qualifying Relative Tests for a Parent

To be your qualifying relative, your parent must meet all four of these tests:

1. Not a Qualifying Child Test Your parent cannot be your qualifying child or anyone else's qualifying child.

2. Member of Household or Relationship Test Your parent automatically meets this test because parents are among the relatives who don't have to live with you to qualify. According to IRS Publication 501, your mother, father, stepmother, stepfather, mother-in-law, and father-in-law all qualify regardless of where they live.

3. Gross Income Test For 2025, your parent's gross income must be less than $5,200 (for 2024, less than $5,050). However, as noted above, the special rule for medical expenses allows you to deduct these expenses even if this test is not met.

Important: Social Security benefits generally are NOT included in gross income for this test unless your parent is married filing separately and lived with their spouse at any time during the year, or if half of the Social Security benefits plus other gross income and tax-exempt interest exceeds the base amount.

4. Support Test You must provide more than half of your parent's total support for the calendar year. Support includes amounts spent for food, lodging, clothing, education, medical and dental care, recreation, transportation, and similar necessities.

The 7.5% AGI Threshold

Your medical expense deduction is limited to the amount of medical expenses that exceeds 7.5% of your adjusted gross income (AGI). Only unreimbursed expenses qualify, you cannot deduct expenses that were compensated by insurance or otherwise.

Example: If your AGI is $80,000, you can only deduct medical expenses exceeding $6,000 (7.5% × $80,000). If you paid $10,000 in qualifying medical expenses, your deduction would be $4,000.

Multiple Support Agreements

If you and your siblings together provide more than half of your parent's support, but no one person provides more than half individually, you may use a multiple support agreement (Form 2120). Under this agreement, one person is designated to claim the parent as a dependent.

According to IRS Publication 502:

• If you are considered to have provided more than half of a qualifying relative's support under a multiple support agreement, you can include the medical expenses you personally pay for that person
• Medical expenses paid by others who joined the agreement cannot be included by anyone
• You can only include the unreimbursed amount you paid

What Medical Expenses Qualify?

According to IRS Topic No. 502, qualifying medical care expenses include payments for:

• Diagnosis, cure, mitigation, treatment, or prevention of disease
• Treatments affecting any structure or function of the body
• Prescription medications
• Doctor, dentist, and hospital fees
• Medical equipment and supplies
• Long-term care services
• Transportation primarily for medical care (including the standard mileage rate for medical expenses, plus tolls and parking)
• Health insurance premiums (in some cases)
• Hearing aids, eyeglasses, contact lenses
• Guide dogs or service animals
• Nursing home costs (if primarily for medical care)

Non-deductible expenses include:

• Nonprescription medicines (except insulin)
• Cosmetic surgery (unless medically necessary)
• General health improvement programs
• Funeral or burial expenses
• Toothpaste, toiletries, or cosmetics

How to Claim the Deduction

1. Itemize deductions on Schedule A (Form 1040)
2. Report total medical expenses on Schedule A, Line 1
3. Enter 7.5% of your AGI on Line 2
4. Subtract Line 2 from Line 1 to calculate your deduction on Line 3
