Yes, medical expenses can be tax-deductible, but there are two conditions you must meet first. Your qualifying medical costs need to exceed 7.5% of your adjusted gross income (AGI), and you need to itemize deductions on Schedule A instead of taking the standard deduction. Only the amount above that 7.5% floor is deductible. For most people, the standard deduction ($16,100 single / $32,200 married filing jointly in 2026) is higher, which means the medical deduction doesn't pay off unless your healthcare costs are high.

Key Takeaways

• The 7.5% rule: Only unreimbursed medical costs above 7.5% of your AGI are deductible.

• Itemizing required: You can't claim the deduction if you take the standard deduction.

• The standard deduction is high: In 2026, it's $16,100 (single) and $32,200 (married filing jointly), so many filers won't benefit from itemizing.

• Self-employed? Different rule: You can deduct 100% of health insurance premiums above the line, without itemizing.

• What qualifies: Doctor visits, prescriptions, dental, mental health, surgery, medical equipment, and more.

• What doesn't qualify: Gym memberships, vitamins, cosmetic procedures, and anything reimbursed by insurance.

Many people assume they can simply write off their medical bills. Here's the thing: You can claim medical expenses on taxes, but only under specific conditions. This guide walks through exactly how the deduction works in 2026, what counts and what doesn't, and whether it's actually worth it for your situation.

How Does the Medical Expense Deduction Work?

The IRS allows you to deduct qualifying unreimbursed medical and dental expenses. But there's a threshold you have to clear first.

According to IRS Topic 502, you can only deduct medical expenses that exceed 7.5% of your AGI. That percentage acts like a floor. Anything below it gives you no tax benefit. Only the amount above it counts.

Here's a simple example. Say your AGI is $80,000. Your floor is $6,000 (7.5% of $80,000). If you had $10,000 in qualifying medical expenses, your deductible amount is $4,000. That $4,000 reduces your taxable income, not your tax bill directly, but the income that gets taxed.

According to the IRS, for the 2026 tax year, only unreimbursed medical expenses that exceed 7.5% of a taxpayer's adjusted gross income are eligible for the itemized deduction on Schedule A, a threshold that remains unchanged from prior years.

And you have to itemize. You can't take the medical deduction and the standard deduction at the same time. That's where it gets tricky for most people.

Standard Deduction vs. Itemizing: Which Makes More Sense?

This is the real question behind whether it's worth claiming medical expenses on taxes.

In 2026, the IRS standard deduction is:

The Tax Policy Center reports that about 91% of tax filers chose the standard deduction in 2022, the most recent year with complete IRS data. That number has stayed high since the Tax Cuts and Jobs Act nearly doubled the standard deduction starting in 2018.

So when does itemizing make sense? When your total itemized deductions, medical expenses, mortgage interest, state and local taxes (up to the SALT cap), and charitable giving, add up to more than your standard deduction. If they don't, you're better off with the standard deduction, and you won't get any tax benefits on medical expenses at all.

Tip: The One Big Beautiful Bill Act raised the SALT cap to $40,000 for married filers in 2026. If you're in a high-tax state and own property, this change may push your itemized total above the standard deduction for the first time in years. It's worth running the numbers. United Tax's tax optimization calculator can help you quickly compare both scenarios.

What Medical Expenses Are Tax Deductible?

The IRS defines a qualifying medical expense as any cost paid for the diagnosis, cure, mitigation, treatment, or prevention of disease. IRS Publication 502 has the complete list, but here are the main categories that count.

Doctor, Dental, and Mental Health Visits

Fees paid to physicians, surgeons, dentists, orthodontists, psychiatrists, psychologists, and other licensed healthcare professionals all qualify. This also includes mental health therapy and addiction treatment programs.

Prescription Medications

Prescription drugs qualify. Over-the-counter medications generally don't, unless a doctor prescribes them to treat a diagnosed condition.

Hospital and Inpatient Care

Inpatient hospital care, including meals and lodging, qualifies when medical treatment is the primary reason for the stay. The same applies to nursing home care when medical necessity is the main reason for residence.

Medical Equipment and Supplies

Eyeglasses, contact lenses, hearing aids, crutches, wheelchairs, dentures, and guide dogs all qualify. So does medical equipment purchased for home use to treat a diagnosed condition.

Transportation for Medical Care

You can deduct the cost of travel to and from medical appointments. This includes gas and oil, or the standard IRS medical mileage rate, plus parking and tolls. Taxi, bus, and ambulance costs count too.

Long-Term Care Insurance Premiums

Premiums for qualified long-term care insurance are deductible up to IRS age-based limits. This is especially useful for retirees and families supporting aging parents.

Fertility Treatments and Other Qualifying Costs

IVF, egg storage, fertility surgery, gender-affirming care, acupuncture, smoking-cessation programs, and weight-loss programs prescribed to treat a specific disease all qualify.

What Medical Expenses Are Not Tax-Deductible?

Here's where people often get tripped up. A lot of health-related spending doesn't qualify.

Can I Write Off Medical Expenses If I'm Self-Employed?

Yes, and self-employed individuals actually get a better deal than employees on this.

If you're self-employed, you can deduct 100% of your health insurance premiums as an above-the-line deduction. That means you take it directly off your income on Form 1040, without needing to itemize and without clearing the 7.5% threshold. It directly reduces your AGI, making it one of the most valuable tax strategies for self-employed individuals.

A lower AGI also has a secondary benefit: it lowers your 7.5% floor, making it easier to qualify for the medical expense deduction on any remaining out-of-pocket costs if you do itemize.

Note: You can't deduct health insurance premiums under the self-employed deduction if you were eligible for coverage through an employer-sponsored plan, yours or your spouse's, at any point during the year.

How to Claim the Medical Expense Deduction: Step by Step

• Find your AGI. This is on Line 11 of your Form 1040. It includes all income, minus above-the-line deductions such as IRA contributions, student loan interest, and self-employed health insurance.

• Calculate your threshold. Multiply your AGI by 0.075. This is your floor. Medical expenses below this amount are not deductible.

• Total your qualifying unreimbursed medical expenses. Include only costs you paid out of pocket that were not reimbursed by insurance or paid from an HSA.

• Subtract the threshold from your total. The amount left over is your potential medical deduction. If it's zero or negative, you don't qualify this year.

• Compare your itemized total to your standard deduction. Add your medical deduction to your other itemized deductions, mortgage interest, SALT, and charitable giving. If that total beats your standard deduction, itemize. If not, take the standard deduction.

• File Schedule A with your Form 1040. Report your medical expenses on Line 1 of Schedule A. The deductible portion goes on Line 4 after the AGI floor is subtracted.

Keep your records. Save receipts, invoices, Explanation of Benefits statements, credit card records, and canceled checks for every expense you claim. The IRS can request documentation from three years prior to the date you filed.

How Do HSAs Interact with the Medical Deduction?

This is a common point of confusion. The short answer: you can't count the same expense twice.

If you paid for a medical expense using your Health Savings Account, that expense is already tax-free. You cannot also claim it as a Schedule A deduction. The IRS doesn't allow double benefits on the same dollar.

That said, HSAs are one of the most powerful medical tax benefits available. For 2026, HSA contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, with an additional $1,000 catch-up contribution for those 55 and older. Contributions reduce your AGI directly, grow tax-free, and withdrawals for qualifying medical expenses are tax-free too.

So here's a practical strategy: use after-tax money for some medical costs to claim the Schedule A deduction, and preserve your HSA balance for larger future expenses or retirement healthcare costs. A tax professional can help you figure out the best split based on your specific numbers.

Frequently Asked Questions

Are medical expenses tax-deductible if I take the standard deduction?

No. To claim tax benefits on medical expenses, you have to itemize deductions on Schedule A. If you take the standard deduction, you can't also claim medical expenses. The two choices are mutually exclusive.

Can I claim medical expenses on taxes for a family member?

Yes. You can deduct qualifying medical expenses you paid for yourself, your spouse, and your dependents, either when the care was provided or when you paid for it. There are some situations where you can also deduct costs for someone who would have qualified as your dependent, but for income or other filing reasons.

Are medical bills tax-deductible even if I paid with a credit card?

Yes. The IRS cares about when you paid, not how. If you charged a medical expense to a credit card in 2026, it counts for the 2026 tax year, even if you haven't paid off the card yet.

Can you claim medical expenses on taxes for a prior year you missed?

Yes. If you forgot to claim a qualifying medical expense in a prior year, you can file an amended return using Form 1040-X. You generally have three years from the date you filed the original return, or two years from when you paid the tax, whichever is later.

Not sure if itemizing is worth it for you?

The decision between itemizing and the standard deduction depends on your full financial picture, not just medical costs. United Tax works with individuals and families year-round to make sure you're not leaving money on the table. Talk to an advisor or try the tax calculator.
