Your Medicare Premiums May Be Tax Deductible — Here's How to Claim Them

Every spring, millions of Medicare beneficiaries file their federal tax returns without claiming a deduction they've legitimately earned all year long. Medicare premiums — the monthly amounts you pay for Part A hospital coverage, Part B outpatient coverage, Part C Medicare Advantage plans, and Part D prescription drug plans — can qualify as deductible medical expenses under IRS rules. Whether you can actually take that deduction depends on how you file, how much you earn, and whether your total medical costs clear a specific threshold. Understanding those rules before you file could meaningfully reduce what you owe.

For most Medicare beneficiaries who are retired employees or not self-employed, the path to deducting Medicare premiums runs through Schedule A, the IRS form for itemized deductions. The catch is the 7.5% floor: you can only deduct the portion of your total qualifying medical expenses that exceeds 7.5% of your adjusted gross income (AGI). If your AGI is $40,000, for example, your medical expenses must surpass $3,000 before a single dollar becomes deductible — and only the amount above $3,000 counts. For a beneficiary with $5,000 in total qualifying medical costs, that means $2,000 is deductible. It's not a dollar-for-dollar benefit, but for people with significant healthcare costs, it adds up quickly.

What counts toward that medical expense total? The IRS allows a broad range of costs beyond just Medicare premiums. Out-of-pocket costs for doctor visits, hospital stays, prescription drugs, dental work, vision care, hearing aids, and long-term care insurance premiums (up to age-based limits) all qualify. In 2025, the standard Part B premium is $185.00 per month — $2,220 per year — for most beneficiaries. Higher earners pay more through Income-Related Monthly Adjustment Amounts (IRMAA), which can push Part B premiums as high as $628.90 per month in 2025. Those IRMAA surcharges are also deductible. Add Part D premiums, any Medigap supplemental insurance premiums, and out-of-pocket costs, and many beneficiaries can clear the 7.5% threshold without realizing it.

Part A premiums are a special case worth understanding. Most people who worked at least 40 quarters (10 years) in Medicare-covered employment pay $0 for Part A. But beneficiaries who worked between 30 and 39 quarters pay $285 per month in 2025, and those with fewer than 30 quarters pay the full $518 per month. If you're in one of those groups and paying a Part A premium, that amount is absolutely deductible as a medical expense, subject to the same 7.5% AGI threshold. People who voluntarily enrolled in Medicare Part A after age 65 without qualifying for premium-free coverage are often unaware they can deduct what they pay.

The rules are considerably more favorable for self-employed beneficiaries. If you run your own business, work as a freelancer, or receive self-employment income — even part-time consulting income in retirement — you may be able to deduct 100% of your Medicare premiums as a business expense adjustment to income. This is reported on Schedule 1 of Form 1040 and reduces your AGI directly, which is far more valuable than an itemized deduction. You don't need to itemize, and you don't need to clear the 7.5% threshold. The only restriction is that you cannot deduct more in premiums than your net self-employment income for the year, and you cannot take this deduction for any month in which you were eligible to participate in an employer-sponsored health plan — including through a spouse's employer.

Medicare Advantage (Part C) premiums are also deductible under the same rules. If you pay a monthly premium for your Medicare Advantage plan — and many plans in 2025 still carry premiums ranging from $0 to over $100 per month depending on your region and plan — those costs qualify. The same applies to standalone Part D prescription drug plan premiums. The average Part D premium in 2025 is approximately $46.50 per month nationally, though costs vary widely by plan and by state. If you're enrolled in a Medicare Savings Program that covers your Part B premium, you cannot deduct the portion the state pays on your behalf — only what comes out of your own pocket counts.

Medigap (Medicare Supplement) premiums deserve special attention because they are among the largest out-of-pocket costs many beneficiaries face and are frequently overlooked at tax time. Monthly Medigap premiums vary enormously by plan type, age, location, and insurer — ranging from under $100 to well over $300 per month for comprehensive plans like Plan G or Plan N. A beneficiary paying $200 per month for a Medigap Plan G policy is spending $2,400 per year on that premium alone. Combined with Part B premiums, Part D premiums, and any remaining out-of-pocket costs, many beneficiaries with Medigap coverage will find their total medical expenses clear the 7.5% AGI threshold, particularly if their retirement income is modest.

One important distinction: premiums paid through payroll deduction on a pre-tax basis — which applies to some people still working and covered under employer group health plans — are generally not deductible again on your tax return, because they were never included in your taxable income to begin with. Medicare premiums deducted from your Social Security benefit, however, are paid with after-tax dollars and are fully eligible for the medical expense deduction. The Social Security Administration sends each beneficiary an SSA-1099 form each January that shows the total Medicare premiums withheld from your benefits during the prior year — that number is your starting point for calculating your deductible premium costs.

To actually claim the deduction, you'll need to compare your potential itemized deductions against the standard deduction for your filing status. For tax year 2025, the standard deduction for single filers age 65 or older is $16,550, and for married couples filing jointly where both spouses are 65 or older, it's $32,300. If your total itemized deductions — including medical expenses above the 7.5% floor, state and local taxes (capped at $10,000), mortgage interest, and charitable contributions — don't exceed those amounts, you're better off taking the standard deduction. But if your medical costs are high, running the numbers both ways with a tax professional or using IRS Free File software is worth the time. IRS Publication 502, available at irs.gov, provides a complete list of qualifying medical expenses and detailed instructions for calculating the deduction correctly.
