Background and History
The Internal Revenue Service (IRS) has long allowed taxpayers to deduct qualified medical expenses to offset the financial burden of healthcare costs. This deduction has evolved, with the current threshold established at 7.5% of adjusted gross income (AGI) for most taxpayers, meaning only medical expenses exceeding this amount are deductible. Introduced to prevent misuse, these rules ensure that only substantial, unreimbursed medical expenses reduce your taxable income.
How Medical Expense Deductions Work
To claim medical expenses as a deduction:
- You must itemize deductions on Schedule A of Form 1040 rather than taking the standard deduction.
- Calculate your total qualified unreimbursed medical and dental expenses paid during the tax year.
- Determine 7.5% of your AGI.
- Subtract this threshold from your total medical expenses; the remaining amount is your deductible deduction.
For example, if your AGI is $50,000, 7.5% equals $3,750. If your unreimbursed medical expenses total $5,000, you can deduct $1,250 ($5,000 – $3,750) on your tax return.
What Qualifies as Medical Expenses?
Qualified expenses must be primarily to diagnose, treat, or prevent disease and include:
- Doctor and hospital visits
- Prescription medications
- Dental care and orthodontics
- Vision care such as eye exams, glasses, and contact lenses
- Medical equipment like wheelchairs and hearing aids
- Long-term care services
- Health insurance premiums paid with after-tax dollars (including some long-term care insurance premiums)
Note that over-the-counter medicines generally do not qualify unless prescribed by a licensed medical professional.
Eligibility Criteria
Any taxpayer who itemizes deductions and has unreimbursed medical expenses exceeding 7.5% of their AGI qualifies to claim this deduction. Taxpayers who take the standard deduction cannot claim medical expenses separately.
Real-Life Examples
- Molly, a freelancer with an AGI of $40,000, had $6,000 in qualified medical expenses. Since 7.5% of $40,000 is $3,000, she can deduct $3,000.
- Joe has an AGI of $60,000 and medical expenses of $2,000. His expenses do not exceed $4,500 (7.5% of his AGI), so he cannot claim a deduction.
Useful Tips for Maximizing Your Deduction
- Maintain thorough records, including receipts and statements, for all medical expenses.
- Include transportation costs directly related to medical care, such as mileage or taxi fares.
- Keep track of health insurance premiums paid with after-tax dollars.
- Consider timing medical payments strategically to surpass the threshold within a single tax year.
- If filing jointly, combine medical expenses with your spouse’s to increase deductible amounts.
Common Mistakes and Misconceptions
- Assuming all medical costs qualify—only IRS-approved expenses count.
- Claiming expenses reimbursed by insurance.
- Trying to deduct medical expenses without itemizing deductions.
- Forgetting to include travel costs for medical treatment.
