If you had high medical bills last year, you may be able to deduct them on your tax return. The medical expense deduction lets you subtract certain unreimbursed health-care costs from your taxable income. But not all health spending counts. The IRS has strict rules on what qualifies and how much you can deduct. Let’s break it down so you can claim what you’re entitled to.
What Is the Medical Expense Deduction?
The medical expense deduction is an itemized deduction on Schedule A. It allows you to deduct qualified medical expenses that exceed 7.5% of your adjusted gross income (AGI). For example, if your AGI is $50,000, you can deduct only the medical costs that exceed $3,750 (7.5% of $50,000). So if you spent $8,000, you can deduct $4,250.
This deduction is only available if you itemize, not if you take the standard deduction. In recent years, the standard deduction has been high, so fewer taxpayers itemize. But if you had a year with major medical events, itemizing might save you more.
What Medical Expenses Qualify for the Deduction?
The IRS defines qualified medical expenses as costs paid for the diagnosis, cure, mitigation, treatment, or prevention of disease. They also include payments for treatments affecting any part or function of the body. Here are the main categories:
Doctor and Hospital Services
Payments to physicians, surgeons, dentists, chiropractors, psychiatrists, and other medical professionals qualify. So do hospital fees, lab fees, and diagnostic tests. This includes everything from a routine checkup to surgery.
Prescription Medications and Insulin
Only drugs prescribed by a doctor are deductible. Over-the-counter medicines like aspirin or allergy pills are not, unless your doctor prescribes them. Insulin is deductible even without a prescription.
Dental and Vision Care
Dental treatments like cleanings, fillings, extractions, dentures, and braces count. Vision care includes eye exams, glasses, contact lenses, and laser eye surgery (LASIK).
Mental Health and Substance Abuse
Payments for psychiatric care, counseling, therapy, and inpatient treatment for substance abuse are qualified. This includes the cost of admission to a therapeutic center or rehab facility.
Long-Term Care and Nursing Home Services
Costs for long-term care services prescribed by a doctor for a chronically ill person are deductible. This includes nursing home care, assisted living, and home health aides. However, if the main reason for entering a nursing home is medical, all costs (including meals and lodging) qualify. If it’s for personal care, only the medical portion qualifies.
Insurance Premiums
You can deduct premiums for medical, dental, and vision insurance. This includes COBRA coverage, Medicare Part B and D, and long-term care insurance (subject to age-based limits). But if your employer pays the premiums, you cannot deduct them.
What Does Not Qualify?
Many health-related expenses don’t meet the IRS definition. Here are common non-qualifying items:
- Cosmetic surgery that is not medically necessary (e.g., facelifts, liposuction).
- Over-the-counter drugs without a prescription (except insulin).
- General health items like toothpaste, vitamins, or gym memberships.
- Health savings account (HSA) or flexible spending account (FSA) contributions.
- Funeral or burial expenses.
- Medical costs reimbursed by insurance or employer.
If you paid for something with tax-free money from an HSA or FSA, you cannot also deduct that expense on your tax return.
How to Claim the Medical Expense Deduction
To claim the deduction, you must itemize on Schedule A. Here’s the step-by-step process:
- Calculate your total qualified medical expenses. Add up all unreimbursed costs from the year. Include payments for you, your spouse, and your dependents.
- Determine your AGI. This is on line 11 of your Form 1040.
- Compute the 7.5% threshold. Multiply your AGI by 0.075. That’s the amount you must exceed to get a deduction.
- Subtract the threshold from your total expenses. The result is your deductible amount.
- Enter the deductible amount on Schedule A, line 1. Then include it in your total itemized deductions.
Example: AGI = $60,000. Total qualified medical expenses = $10,000. Threshold = $60,000 x 7.5% = $4,500. Deductible = $10,000 – $4,500 = $5,500.
Comparison Table: Qualified vs. Non-Qualified Expenses
| Qualified Expenses | Non-Qualified Expenses |
|---|---|
| Doctor visit copays | Cosmetic surgery |
| Prescription medications | Over-the-counter drugs (no script) |
| Dental fillings | Toothpaste |
| Eyeglasses | Gym memberships |
| Psychotherapy | Vitamins |
| Nursing home (medical care) | Funeral expenses |
| Medicare premiums | HSA contributions |
Recordkeeping: What You Need to Keep
Always save receipts, bills, and proof of payment. For each expense, note the date, amount, the provider’s name, and what it was for. If you were reimbursed later, keep records of that too. You may also need a letter from your doctor stating that a specific treatment was medically necessary, especially for expenses like weight-loss programs or special schooling for a disabled dependent.
Good recordkeeping also helps you when setting up your financial systems. For guidance on organizing your finances, check out our guide on how to set up a bookkeeping system for your small business. Though designed for businesses, the principles of tracking expenses apply to personal deductions as well.
Common Mistakes to Avoid
Many people miss out on the deduction because they don’t itemize or miscalculate qualifying expenses. Here are pitfalls to watch for:
- Forgetting to include premiums. Health insurance premiums paid out-of-pocket count.
- Including reimbursed expenses. Only unreimbursed costs are deductible.
- Overlooking travel costs. Mileage for medical appointments (at the IRS rate) and transportation expenses (taxi, bus) are deductible.
- Not considering dependents. If you pay medical bills for a dependent, include them.
- Ignoring the 7.5% threshold. Many assume they can deduct all expenses, but only the amount above the threshold counts.
If you run a business, managing your finances well can free up time to focus on deductions. Learn the differences between bookkeeping and accounting to ensure your records are accurate.
How to Decide Whether to Itemize
Before you start counting medical expenses, check if itemizing is worth it. Add up all your potential itemized deductions—mortgage interest, state and local taxes (up to $10,000), charitable donations, and medical expenses. If the total is less than the standard deduction for your filing status, you won’t benefit from itemizing. For 2024, the standard deduction is $14,600 for single filers and $29,200 for married filing jointly. If your total itemized deductions are just below those amounts, adding medical expenses might push you over the edge.
One strategy: If you have flexibility in scheduling elective medical procedures, consider bunching expenses into a single year to exceed the 7.5% threshold. For example, if you need a costly surgery and can schedule it in the same year as other large medical costs, you may clear the AGI floor and get a deduction. This works especially well if you alternate between itemizing and taking the standard deduction in different years.
What About the Alternative Minimum Tax (AMT)?
The medical expense deduction is one of the few that survives the alternative minimum tax. Under the AMT, you still can deduct medical expenses that exceed 7.5% of AGI. But note that if you are subject to the AMT, some other itemized deductions may be reduced or eliminated. The medical deduction remains intact, making it even more valuable if you’re in an AMT situation. Check your AMT liability or use tax software to see how the deduction affects your overall tax bill.
Final Thoughts
The medical expense deduction can provide significant savings if your health costs pile up. But it requires careful recordkeeping and itemizing. Always check the IRS guidelines or consult a tax professional to confirm what qualifies in your situation. Remember, even if you use an HSA or FSA, tracking your expenses helps you maximize all available tax breaks.
