Tax-Deductible Medical Expenses for Seniors: Premiums, Care, and AGI

Tax deductible medical expenses for seniors are unreimbursed medical and dental costs that exceed 7.5% of your adjusted gross income, claimed on Schedule A of Form 1040.¹ You have to itemize to use the deduction, and because older adults now qualify for a stack of standard deduction add-ons, itemizing usually pays off only in a year with unusually heavy medical bills.

The 7.5% AGI Floor

Only the portion of your medical spending above 7.5% of your AGI counts. Anything below the floor is lost.² The expenses can be for you, your spouse, or your dependents, but any amount reimbursed by insurance or another source has to come out first.

A quick example. If your AGI is $50,000, the floor is $3,750. If you paid $10,000 in unreimbursed medical costs, $6,250 is deductible. At $80,000 of AGI, the floor is $6,000 and the same $10,000 yields only $4,000. Lower-income seniors clear the floor faster, but they also have less other deduction material to work with.

Will Itemizing Actually Help?

Medical expenses only matter if your itemized total beats the standard deduction. For 2026, the base standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.³ Taxpayers 65 and older add $2,050 (single) or $1,650 per qualifying spouse (joint) on top.

From 2025 through 2028, seniors also get a new enhanced deduction of $6,000 per person, or $12,000 for a married couple where both spouses are 65 or older. It phases out above $75,000 of modified AGI for singles and $150,000 for joint filers, and it applies whether or not you itemize.⁴

Stacked up, a single senior under the phase-out has a combined standard deduction near $24,150. A qualifying 65-and-older couple can reach roughly $47,700. Those are high bars. The medical deduction tends to pay off in a year with a large one-time event (surgery, a nursing home move, major dental work) and enough other itemized deductions, like state and local taxes, mortgage interest, and charitable gifts, to carry the total over the top.

What Counts as a Medical Expense

The IRS defines a medical expense as the cost of diagnosing, treating, or preventing disease, or anything that affects a structure or function of the body, as long as the expense is primarily medical rather than something you would buy anyway.² For seniors, the most relevant categories include:

Payments to doctors, surgeons, dentists, chiropractors, psychiatrists, psychologists, and other licensed providers.
Inpatient hospital costs, lab work, and nursing wages, whether the care happens in a facility or at home.
Prescription drugs and insulin. Over-the-counter medications generally do not qualify.
Hearing aids (including batteries, repairs, and maintenance), wheelchairs, walkers, crutches, prescription eyeglasses, and contact lenses.
Dental and vision care: fillings, extractions, dentures, braces, eye exams, and corrective procedures.
The cost of buying, training, and maintaining a guide dog or other service animal for a person with a disability, including food, grooming, and veterinary care.

Food is almost always a personal expense, but there is a narrow exception. The extra cost of medically prescribed food is deductible when the food does not satisfy normal nutritional needs, it treats or alleviates an illness, and a physician has substantiated the need.⁵ Even then, only the amount above what you would normally spend on food counts. Vitamins and supplements taken for general health do not qualify.

Medicare and Other Insurance Premiums

Medicare premiums are usually the largest recurring medical cost a senior has, and most of them are deductible. The standard Medicare Part B premium is $202.90 per month in 2026, which adds up to $2,434.80 a year.⁶ Part D premiums, Medicare Advantage premiums, and Medigap premiums all qualify as well.²

One limit matters: premiums paid with pre-tax money, like paycheck deductions taken before taxes, are not deductible, because that money was never taxed to begin with. Medicare premiums deducted from your Social Security benefits are paid with after-tax dollars, so they do count.

Self-employed seniors get a better route. Instead of running Medicare premiums through the 7.5% floor, they can take them as a self-employed health insurance deduction, which reduces AGI directly.⁷ It covers Part B, Part D, Medigap, and Medicare Advantage. You cannot claim it for any month you were eligible for a subsidized plan through an employer, including a spouse’s employer.

Long-Term Care Services and Premiums

Qualified long-term care services are deductible when a chronically ill person needs them and a licensed healthcare provider has prescribed them. That covers rehabilitative and therapeutic services and personal care like help with bathing, dressing, or eating.²

Premiums for a qualified long-term care insurance policy are deductible too, but only up to an age-based annual cap. For 2026:

Age 40 or under: $500
Age 41 to 50: $930
Age 51 to 60: $1,860
Age 61 to 70: $4,960
Age 71 or older: $6,200

These caps are per person. If you and your spouse both carry policies, each applies the bracket for your own age. The eligible premium amount then joins the rest of your medical expenses and runs through the 7.5% AGI floor like everything else.¹ Long-term care premiums do not skip the threshold.

Nursing Homes and Assisted Living

Whether residential care is deductible turns on one question: is the person there primarily for medical care? If yes, the entire cost of the facility, including room and board, is deductible after any insurance reimbursement. If not, only the medical portion qualifies, and the lodging and meals do not.⁸

This matters most in assisted living, where residents often need a mix of medical and personal help. A physician’s certification that the resident is chronically ill and needs the level of care the facility provides supports deducting the full cost. Without that certification, you are usually limited to specifically medical charges like skilled nursing or physical therapy. Ask the facility for an itemized breakdown of medical versus non-medical charges at the start of each year.

Home Modifications

Improvements made for a medical condition are deductible, but only to the extent they do not increase the home’s value. Spend $10,000 on a wheelchair ramp that an appraiser says added $6,000 of value, and only $4,000 is a medical expense.² Common qualifying changes include entrance ramps, widened doorways, grab bars, stairway lifts, and lowered cabinets. Some, like handrails or accessible bathroom fixtures, rarely add market value at all, so the full cost generally counts.

Operating and maintenance costs for medically necessary equipment and modifications are also deductible, even if the installation was only partly deductible. If a prescribed air filtration system adds $40 a month to your electric bill, that $480 a year is a medical expense.

Travel for Medical Care

Getting to and from treatment counts. Bus, taxi, train, plane, and ambulance fares are deductible. If you drive, you can deduct actual out-of-pocket costs like gas and oil, or use the IRS standard medical mileage rate of 20.5 cents per mile for 2026.⁹ Parking and tolls add on top either way.²

Out-of-town treatment that requires an overnight stay allows a lodging deduction of up to $50 per night per person. The cap applies to the patient and to a necessary companion, so a trip with one companion can run up to $100 a night. The lodging has to be primarily for medical care at a licensed hospital or an equivalent facility, with no significant vacation element. Meals during medical travel are not deductible.¹

What Does Not Qualify

Some health-related spending is specifically excluded:

Cosmetic procedures, unless they correct a deformity caused by illness, injury, or a congenital abnormality.
Over-the-counter drugs other than insulin, including pain relievers, cold medicine, and allergy pills.
Vitamins and supplements taken for general health, unless a physician prescribes them for a specific diagnosed condition.
Gym memberships and health club dues, even when a doctor recommends exercise.
Toiletries and personal care items like toothpaste and sunscreen.
Funeral and burial costs, regardless of the cause of death.

Timing Matters

Medical expenses are deductible in the year you pay them, not the year you receive the care. A procedure in December paid for in January belongs on the next year’s return. Credit card charges count in the year you swipe the card.

That creates a real planning opportunity. If your spending for the year is close to the 7.5% floor, bunching elective costs like dental implants or new hearing aids into that same year can push the total over the line. Spread the same costs across two years and neither year may clear the floor, which wipes out the deduction entirely. Checking your running medical total mid-year is often enough to tell you whether to accelerate or defer.

Keeping Records

Save every receipt, bill, and explanation of benefits. The IRS can examine a return for up to three years after filing, and a deduction without documentation gets disallowed.¹⁰ EOB statements from your insurer are especially useful because they show exactly how much of a bill was unreimbursed.

The calculation itself is simple. On Schedule A, total your qualifying medical and dental expenses, subtract 7.5% of your AGI, and the remainder is your medical deduction. Add it to your other itemized deductions and compare the total to your standard deduction to decide which route to take.
