Understanding Medical Expense Deductions on Your Taxes

Medical expense deductions are a way to reduce the income taxes you owe if you have significant healthcare costs. When you file your federal income tax return, the Internal Revenue Service (IRS) allows you to deduct certain medical and dental expenses if they exceed a specific threshold. This deduction applies only if you itemize deductions on your tax return rather than taking the standard deduction.

The IRS defines qualified medical expenses as costs paid for diagnosis, cure, mitigation, treatment, or prevention of disease, or for treatments affecting any part or function of the body. This includes expenses for yourself, your spouse, and your dependents. The key concept is that these must be out-of-pocket costs—amounts you paid directly—not expenses covered by insurance.

For the 2023 tax year, you can only deduct medical expenses that exceed 7.5% of your adjusted gross income (AGI). This means if your AGI is $60,000, you would need medical expenses exceeding $4,500 before you could deduct any amount. The threshold is 7.5% for all taxpayers, regardless of age. This percentage has remained stable since 2013 and applies to federal income taxes.

Understanding whether you can benefit from medical deductions requires knowing your total household income and your total medical expenses for the year. Many people with chronic conditions, major surgeries, or ongoing treatments find that their medical costs do exceed this threshold. For example, someone paying $3,000 annually for prescriptions, $2,000 for physical therapy, and $1,500 for dental work would have $6,500 in medical expenses. If their AGI is $70,000, they would exceed the $5,250 threshold and could deduct $1,250.

Practical Takeaway: Add up all your out-of-pocket medical expenses for the year, then calculate 7.5% of your AGI. Only medical costs above that amount matter for your deduction. Keep records of all medical expenses throughout the year rather than trying to remember them during tax time.

What Counts as Deductible Medical Expenses

The IRS maintains a detailed list of medical expenses you can deduct. These fall into several broad categories: insurance premiums, prescription medications, medical equipment and devices, treatment services, and transportation related to medical care. Knowing what qualifies prevents you from missing deductions or claiming expenses that don't count.

Prescription medications and insulin are fully deductible. Over-the-counter medications are deductible only if you have a prescription for them—for example, a doctor-prescribed antibiotic ointment counts, but over-the-counter pain relievers do not. This distinction matters because many people take over-the-counter medications but assume they cannot deduct them.

Medical equipment and supplies that you purchase are generally deductible. This includes:

• Wheelchairs, crutches, and walkers
• Hearing aids and cochlear implants
• Eyeglasses and contact lenses
• Artificial limbs and prosthetics
• Diabetes testing supplies and monitors
• Blood pressure monitoring devices
• Medical alert systems
• Oxygen equipment and supplies

Treatment services covered include doctor visits, hospital stays, surgical procedures, physical therapy, mental health counseling, dental work, orthodontia, and vision correction procedures like LASIK. If you paid out of pocket for these services, the full amount counts toward your deduction. Laboratory tests and diagnostic imaging such as X-rays, MRIs, and CT scans also qualify.

Insurance-related expenses deserve special attention. You can deduct health insurance premiums you paid yourself, including COBRA continuation coverage. Self-employed individuals can deduct health insurance premiums under a separate rule that doesn't require itemizing. Medicare premiums for parts B, C, and D are deductible. Long-term care insurance premiums are deductible, though there are age-based limits on the amounts.

Transportation to and from medical care is deductible. You can deduct actual expenses, such as parking and tolls at medical facilities, or use the IRS standard mileage rate for medical travel. For 2023, the medical mileage rate was 21 cents per mile. This applies to driving to doctor appointments, hospitals, physical therapy, dialysis centers, or any location where you receive medical care.

Practical Takeaway: Create a spreadsheet listing each medical expense category with dates and amounts. Separate prescription medications from over-the-counter ones. Track mileage for medical appointments or calculate the dollar amount using the standard mileage rate. This organization makes it easier to report accurately on your tax return.

What Does Not Count as Medical Deductions

Understanding what the IRS does not allow as medical deductions is equally important as knowing what qualifies. Many people lose potential tax savings by claiming expenses that don't meet IRS rules, or they waste time tracking expenses that won't help their tax situation.

General health and wellness expenses are not deductible. This means you cannot deduct gym memberships, swimming lessons for fitness, or general nutritional supplements unless a doctor specifically prescribes them to treat a medical condition. A multivitamin for overall health does not count, but a prescribed supplement for a diagnosed deficiency may. Weight loss programs and diet programs are typically not deductible unless they are medically prescribed to treat a disease such as obesity diagnosed by a doctor.

Cosmetic procedures are not deductible. This includes:

• Teeth whitening
• Facial fillers or Botox
• Hair removal treatments
• Cosmetic surgery that doesn't treat a medical condition
• Skin care products for appearance

However, reconstructive surgery following an injury or disease may be deductible. If you had surgery to repair a burn or reconstruct a breast after cancer treatment, those costs could qualify. The distinction is whether the procedure treats a medical condition or simply improves appearance.

Travel and lodging expenses for medical care are not deductible as medical expenses. If you travel to a different city for treatment, you cannot deduct hotel costs or airfare, even though the purpose is medical. This applies even if a doctor recommends travel for your health. The exception is if you require a companion to accompany you due to a medical condition—you may be able to deduct the companion's expenses, but not your own travel costs beyond actual medical care.

Insurance plan deductibles and copayments, once you've paid them, are considered medical expenses. However, health insurance premiums you paid through a payroll deduction with pre-tax dollars were already deducted from your income, so you cannot deduct them again. Only out-of-pocket premium payments count.

Childcare is never deductible as a medical expense, even if a parent needs childcare to attend medical appointments. Household help and attendant care in your home, while sometimes deductible under other circumstances, are not medical expenses for tax purposes.

Practical Takeaway: Before recording an expense, ask: "Is this treating or preventing a disease or medical condition, or is this for general health and wellness?" If it's the latter, do not include it. When in doubt, reference the IRS Publication 502 or consult with a tax professional rather than guessing.

Tracking and Documenting Medical Expenses Throughout the Year

The difference between successfully claiming medical deductions and losing them often comes down to documentation. The IRS may ask you to prove the expenses you claimed, and without records, you cannot substantiate your deduction. Good record-keeping throughout the year takes minimal effort but yields significant results.

Keep all receipts and invoices from medical providers. When you pay for a doctor visit, prescription, medical equipment, or therapy session, retain the receipt even if you paid with insurance. Many medical bills show what portion your insurance paid and what you paid out of pocket—this clarifies exactly what you can deduct. If you receive a statement from your health insurance company showing your out-of-pocket costs, print and save it.

For prescription medications, save the receipts from the pharmacy. These receipts show the medication
