Medical Expense Deduction – The 7.5% AGI Threshold

Category: Tax Planning for Seniors | FinSeniors, Worthune.com

Healthcare costs are one of the biggest financial concerns in retirement — and for some retirees, they're also a meaningful source of tax deductions. The IRS allows you to deduct qualified medical expenses that exceed 7.5% of your Adjusted Gross Income (AGI), but only if you itemize deductions. For retirees with significant out-of-pocket healthcare costs, this deduction can be worth hundreds or even thousands of dollars.

The challenge is knowing what qualifies, understanding when itemizing actually makes sense given the enhanced senior standard deduction, and capturing all the expenses you're entitled to deduct.

The medical expense deduction is a floor, not a credit. You can only deduct the portion of your qualified medical expenses that exceeds 7.5% of your AGI. For example:

Only if you have enough other itemized deductions (mortgage interest, state/local taxes, charitable contributions) to exceed the standard deduction does this deduction actually save you anything. Many retirees find that a year of high medical expenses is the one year they can justify itemizing.

Healthcare Providers and Treatments

• Payments to doctors, dentists, surgeons, chiropractors, psychiatrists, and psychologists

• Hospital and nursing home care

• Physical therapy, occupational therapy, speech therapy

• Eye exams, glasses, and contact lenses

• Hearing aids and batteries

• Dental care including braces, dentures, and extractions

• Acupuncture (if prescribed for a medical condition)

• Addiction treatment programs (alcohol, drug, nicotine cessation)

Insurance Premiums

• Medicare Part B and Part D premiums (if not deducted from your paycheck pre-tax)

• Medicare Advantage and Medigap supplement insurance premiums

• Long-term care insurance premiums — up to the age-based IRS limit (see table below)

• COBRA premiums if you're paying for continuation coverage

• Qualified health insurance premiums if you're self-employed (deducted on Schedule 1, not Schedule A)

Long-Term Care Insurance Premium Limits (2026)

💡 These LTC premium limits are per person. A married couple where both pay LTC premiums can potentially deduct up to two times the applicable age-based limit.

Home Modifications for Medical Purposes

Home improvements made primarily for medical reasons — not for aesthetic or property value purposes — may be deductible. The deductible amount is the cost of the improvement minus any increase in the home's fair market value.

• Wheelchair ramps and widened doorways

• Grab bars, handrails, and non-slip surfaces in bathrooms

• Stairlifts and elevators installed for a medical condition

• Air filtration systems or air conditioning for severe respiratory conditions (doctor must prescribe)

• Pool or exercise equipment prescribed by a physician for a specific medical condition (deductible only to the extent it exceeds any FMV increase)

Transportation

• Mileage driven to and from medical appointments: 21 cents per mile for 2024 (check current IRS rate for 2026)

• Ambulance transportation

• Bus, taxi, or rideshare to medical appointments if you're unable to drive

• Parking fees at medical facilities

Prescription Drugs and Medical Devices

• Prescription medications (not over-the-counter drugs, with limited exceptions)

• Insulin and diabetes supplies

• Prescribed medical devices: crutches, wheelchairs, walkers, blood pressure monitors

• CPAP and BIPAP machines and supplies for sleep apnea

• Prosthetics and orthopedic appliances

• Cosmetic surgery (unless to correct a deformity arising from disease or accident)

• Non-prescription vitamins, supplements, or health foods

• Gym memberships (even if doctor recommends exercise — unless specifically prescribed for a disease)

• Teeth whitening or other purely cosmetic dental procedures

• Maternity clothes, diapers, or baby formula

• Funeral expenses

• Health insurance premiums paid with pre-tax dollars (e.g., through an employer plan)

If the primary reason for being in a nursing home or assisted living facility is medical care, the entire cost — including meals and lodging — may be deductible. If the primary reason is custodial rather than medical (i.e., you can't live independently but don't require skilled nursing care), only the medical components are deductible. The distinction matters and can be worth discussing with a tax professional in your specific situation.

Because the 7.5% threshold applies annually, you may be able to boost your medical deduction by bunching elective procedures into a single year. If you need dental work, new glasses, hearing aids, and an elective procedure, scheduling them all in the same calendar year instead of spreading them across two years can push you over the threshold and allow a meaningful deduction.

This bunching strategy pairs well with itemizing in the same year you bunch charitable contributions through a DAF — both strategies benefit from concentrating expenses in a high-deduction year.

• Keep all receipts, Explanation of Benefits (EOBs) from insurers, and provider invoices

• Track mileage for every medical trip in a log (date, destination, purpose, miles)

• Keep premium statements for Medicare, Medigap, and LTC insurance

• For home modifications, get contractor invoices and a home appraisal to document any increase in FMV

• Organize receipts by category to make reporting easier
