If you’re paying more out of pocket for doctor visits, dental work, hearing aids, or Medicare premiums than you used to, you’re not imagining it. The good news: a lot of that spending can reduce your federal tax bill through the medical expense tax deduction. Here’s exactly how the 2026 rules work, what qualifies, and how to figure out if claiming it actually makes sense for you.

What Is the Medical Expense Tax Deduction?

The medical expense deduction is an itemized deduction you claim on Schedule A of Form 1040. It lets you deduct unreimbursed medical and dental expenses you paid for yourself, your spouse, and your dependents during the tax year.

This deduction matters more than ever for retirees. Medicare premiums keep climbing, dental and vision care usually isn’t covered by Medicare at all, and long-term care costs can run into tens of thousands of dollars a year. If you’re 55 to 75 and covering more of your own health costs, this deduction is worth understanding even if you’ve never itemized before.

The 7.5% AGI Threshold Explained

Here’s the part that trips people up: you can’t deduct all of your medical expenses. You can only deduct the portion that exceeds 7.5% of your adjusted gross income (AGI).

This threshold applies to everyone, regardless of age. It isn’t a special break just for people 65 and older — it’s a permanent rule under current law.

Worked Example: Calculating Your Deductible Amount

Step	Calculation	Amount
1. Adjusted Gross Income (AGI)	Example figure	$60,000
2. 7.5% AGI floor	$60,000 x 0.075	$4,500
3. Total unreimbursed medical expenses for the year	Example figure	$9,200
4. Deductible amount	$9,200 – $4,500	$4,700

In this example, only $4,700 of the $9,200 spent actually reduces taxable income — not the full amount. That’s why it’s important to know your real AGI before assuming this deduction will help you.

What Medical Expenses Qualify

Common Qualifying Costs

• Doctor, dentist, and vision visits and treatments
• Prescription drugs and insulin
• Medicare Part B and Part D premiums, and Medigap premiums
• Hearing aids and batteries
• Long-term care insurance premiums (subject to age-based dollar limits set annually by the IRS)
• Mileage driven to and from medical appointments (at the IRS standard medical mileage rate)

Less Obvious Qualifying Costs

• Home modifications made for medical necessity, such as wheelchair ramps, grab bars, or widened doorways (the cost may need to be reduced by any increase in your home’s value)
• Certain nursing home or long-term care facility costs, when the primary reason for being there is medical care rather than just housing

What Does NOT Qualify

• Cosmetic procedures that aren’t medically necessary
• General health club or gym memberships
• Over-the-counter vitamins and supplements without a prescription

Itemizing vs. Standard Deduction — Is It Worth It?

Claiming the medical expense deduction only helps if your total itemized deductions are higher than the standard deduction you’d get anyway. To compare, add up:

• Your deductible medical expenses (after the 7.5% AGI floor)
• State and local taxes (SALT), up to the allowed cap
• Mortgage interest
• Charitable contributions

Then compare that total against the 2026 standard deduction for your filing status (plus the additional deduction available for filers age 65 and older). If your itemized total is higher, itemizing wins.

When Itemizing Medical Expenses Usually Makes Sense

• You had a major one-time medical event (surgery, hospitalization) with large out-of-pocket costs
• A family member had an extended nursing home or long-term care stay
• You paid for significant dental work, such as implants or dentures, not covered by insurance

How to Claim the Deduction — Step by Step

1. Track and total your qualifying expenses. Keep receipts, Explanation of Benefits (EOB) statements, and mileage logs throughout the year.
2. Calculate your 7.5% AGI floor using your final AGI from your tax return.
3. Subtract the floor from your total qualifying expenses to get your deductible amount.
4. Report the deduction on Schedule A, Lines 1 through 4 of Form 1040.

For the complete, authoritative list of what does and doesn’t qualify, refer to IRS Publication 502 — it’s updated annually and is the definitive source the IRS itself uses.

Common Mistakes to Avoid

• Forgetting to subtract insurance reimbursements. You can only deduct the portion you actually paid out of pocket, not amounts your insurance reimbursed.
• Including premiums already paid pre-tax. If your employer plan premiums come out of your paycheck before taxes, you can’t deduct them again — that would be double-dipping.
• Missing travel and mileage deductions. Trips to the pharmacy, doctor, dentist, and therapy appointments add up over a year and are easy to forget to log.

FAQ

Can I deduct Medicare premiums?

Yes. Medicare Part B premiums, Part D premiums, and Medigap (supplemental) premiums all count as qualifying medical expenses, as long as you’re paying them yourself and not through a pre-tax payroll deduction.

Can I deduct a family member’s medical expenses I paid for?

In many cases, yes — if you paid medical expenses for a spouse or a dependent, those costs can generally be included in your own total, subject to the same 7.5% AGI floor. Check IRS Publication 502 for the specific rules on who qualifies as a dependent for this purpose.

Does this change if I’m 65 or older?

The 7.5% AGI threshold itself is the same regardless of age. However, filers 65 and older may qualify for an additional standard deduction amount, which can affect whether itemizing is worth it in the first place.
