Medical Expense Deductions for Retirees: What Medicare Beneficiaries Can Write Off in 2025

Retirees on Medicare often have significant healthcare costs — and many are surprised to learn that Medicare premiums, out-of-pocket costs, and other medical expenses can qualify for the federal medical expense deduction. Understanding the intersection of Medicare and the tax code can mean real money saved for people on fixed incomes. Here’s a complete guide for 2025.

Are Medicare Premiums Tax Deductible? Yes.

Medicare premiums are explicitly listed as deductible medical expenses by the IRS. This includes:

Medicare Part B premiums — The standard Part B premium is $185/month ($2,220/year) in 2025, though higher-income retirees pay Income-Related Monthly Adjustment Amounts (IRMAA) that can be significantly higher. All of these premiums are deductible.
Medicare Part D premiums — Prescription drug plan premiums are deductible, including any IRMAA surcharges
Medicare Part A premiums — Most people don’t pay a Part A premium (because they worked 40+ quarters), but those who do pay are eligible to deduct those premiums
Medicare Supplement (Medigap) premiums — Premiums for Medigap policies that cover Medicare cost-sharing are deductible
Medicare Advantage (Part C) premiums — The additional premium you pay for a Medicare Advantage plan above the standard Part B premium is deductible

Medicare Cost-Sharing: Deductibles, Copays, and Coinsurance

Beyond premiums, the out-of-pocket costs you pay when you use Medicare services are also deductible:

Part A deductible — The per-benefit-period hospital deductible ($1,676 in 2025)
Part B annual deductible — The annual deductible before Medicare pays ($257 in 2025)
Part B coinsurance — The 20% you pay for doctor visits, outpatient services, and durable medical equipment after meeting the deductible
Part D cost-sharing — Prescription drug copays and coinsurance under your Part D plan
Costs for non-covered Medicare services — If you receive a service Medicare doesn’t cover and you pay out of pocket, those costs are potentially deductible if they qualify as medical expenses

Why the 7.5% AGI Threshold Works in Retirees’ Favor

The 7.5% AGI threshold is the key to unlocking the medical expense deduction — and it often works in retirees’ favor for two reasons: lower income and higher healthcare costs.

With a lower retirement income, 7.5% of your AGI is a lower dollar amount. And with Medicare premiums, out-of-pocket costs, prescription drugs, dental work, vision care, and other healthcare expenses, total medical costs in retirement can be substantial. This combination frequently means retirees clear the 7.5% floor when working-age adults might not.

Example: If your AGI is $40,000, your 7.5% threshold is just $3,000. Medicare Part B and Part D premiums alone ($2,220 + $500 = $2,720) get you close. Add a few prescription copays, a dental procedure, and an eye exam, and you’ve cleared the floor.

What Retirees Often Overlook

Many retirees don’t realize how many Medicare-related and other medical costs count toward the deduction:

Long-term care insurance premiums — Up to $5,960 for those 71 and older in 2025 (age-based limits apply)
Assisted living costs — When medical care is the primary reason for the facility, a portion (or all) of the cost may be deductible
Home health care — Costs for a home health aide providing medical or nursing care (not just household help) are deductible
Transportation to medical appointments — Mileage at the medical rate (21 cents per mile in 2025), parking fees, and taxi/rideshare costs to medical visits
Hearing aids — Medicare traditionally doesn’t cover hearing aids; if you pay out of pocket, these are deductible
Dental work — Medicare doesn’t cover most dental care; all qualifying dental costs you pay are deductible
Vision care — Medicare doesn’t cover routine vision care; glasses, contact lenses, and eye exams are deductible

Medicare Premiums Deducted as Self-Employed Health Insurance

If you’re still doing self-employment work in retirement, there’s an even better deduction available. Self-employed individuals can deduct Medicare premiums as self-employed health insurance — an above-the-line deduction that doesn’t require itemizing and isn’t subject to the 7.5% AGI threshold. This can be significantly more valuable than the Schedule A deduction for retirees with self-employment income. You can’t deduct these premiums under both the self-employed health insurance deduction and Schedule A for the same amounts.

The Standard Deduction vs. Itemizing for Retirees

Retirees who are 65 or older receive a higher standard deduction. In 2025, the additional standard deduction amount is $2,000 per person (65 or older and/or blind). So a married couple both over 65 gets $4,000 more in standard deduction on top of the baseline $30,000 — for a total of $34,000. This higher threshold makes it harder to benefit from itemizing, even with Medicare costs.

However, retirees with significant medical expenses (large dental bills, long-term care costs, hearing aids, or high Medicare surcharges from IRMAA) combined with property taxes, mortgage interest, or charitable deductions may still find itemizing worthwhile.

Social Security and Medicare Premiums: Not Auto-Deducted

Many retirees have Medicare Part B and D premiums automatically deducted from their Social Security benefits. These deductions are still your premiums paid out-of-pocket for tax purposes — the fact that Social Security deducts them doesn’t change their deductibility. Your Medicare Statement (or SSA-1099) will show the amounts deducted for premiums.

How to Claim Medicare Expenses as Deductions

To claim Medicare premiums and out-of-pocket costs on your taxes: gather your Medicare Summary Notices (MSN) and Explanation of Benefits showing what you paid, note your premium amounts from your SSA-1099, compile records of all other qualifying medical expenses for the year, and report all qualifying costs on Schedule A, subject to the 7.5% AGI floor.

The Bottom Line

Medicare premiums — including Part B, Part D, Medigap, and Medicare Advantage premiums — are deductible medical expenses. So are Medicare deductibles, copays, and coinsurance. Combined with other out-of-pocket healthcare costs that Medicare doesn’t cover (dental, vision, hearing aids, long-term care), many retirees will find they have enough medical expenses to benefit from itemizing. The lower incomes typical in retirement make it easier to clear the 7.5% AGI threshold. If you’re on Medicare and haven’t been carefully tracking your healthcare costs for tax purposes, you may be leaving a meaningful deduction on the table.
