Medicare Part B premiums are not tax deductible for most people

If you pay Medicare Part B premiums out of your own pocket, you cannot deduct them on your federal income tax return. The IRS does not allow deductions for Medicare premiums, whether you pay them monthly or have them withheld from your Social Security check. This applies to the standard Part B premium and any additional income-related monthly adjustment amounts (IRMAA) you may owe.

The one exception is narrow: if you are self-employed and pay Part B premiums as part of your self-employment health insurance deduction, you may be able to deduct them. This requires specific circumstances and IRS Form 1040 Schedule C. Most people with W-2 jobs or retirees on Social Security cannot use this route.

Understanding what is and is not deductible matters because it affects how much you actually owe in taxes. Many people assume health-related costs are deductible and miss the fact that Medicare premiums are not among them.

Key Takeaways

  • Medicare Part B premiums cannot be deducted on your federal tax return unless you are self-employed and pay them as part of your self-employment health insurance deduction.
  • This rule applies whether you pay premiums directly to Medicare or have them deducted from your Social Security benefits.
  • You cannot deduct IRMAA (income-related adjustment amounts) that you owe on top of your standard Part B premium.
  • Medical expenses that exceed 7.5 percent of your adjusted gross income may be deductible, but Medicare premiums do not count toward that threshold.

Why Medicare premiums are treated differently from other health costs

The IRS separates health insurance premiums from other medical expenses. You cannot deduct premiums for Medicare Part B, Part D (prescription drug coverage), or Medigap supplemental insurance on your personal tax return. This is true even though you must pay them and they are health-related.

Other health costs—such as copays, coinsurance, deductibles, and out-of-pocket prescription costs—can count toward the medical expense deduction, but only if your total medical expenses exceed 7.5 percent of your adjusted gross income (AGI). Medicare premiums themselves never count, even if you have other large medical bills.

The distinction exists because Medicare is a federal program, and the IRS treats it as a separate category from private health insurance or out-of-pocket medical care.

The self-employed exception and how it works

If you are self-employed and have net self-employment income, you may deduct health insurance premiums—including Medicare Part B—as a business expense. This deduction appears on IRS Form 1040, Schedule C, and reduces your taxable income before you calculate self-employment tax.

To use this deduction, you must have self-employment income in the year you claim it. You cannot deduct more in premiums than you earned from self-employment. If you are retired and have no self-employment income, this exception does not explore to you, even if you had self-employment income in previous years.

You also cannot claim the same premium as both a self-employed deduction and as part of the medical expense deduction. You must choose one method. Most self-employed people benefit more from the self-employment deduction because it reduces both income tax and self-employment tax.

How IRMAA affects your tax situation

If your modified adjusted gross income (MAGI) exceeds certain thresholds, Medicare charges you an Income-Related Monthly Adjustment Amount (IRMAA) on top of your standard Part B premium. These additional amounts are also not tax deductible.

IRMAA is based on your tax return from two years prior. For example, in 2024, Medicare uses your 2022 tax return to calculate IRMAA. If your income changes significantly—such as from a large withdrawal from a retirement account or the sale of property—you may owe higher IRMAA amounts that year. These amounts still cannot be deducted.

You can request that Medicare recalculate your IRMAA if your income dropped due to retirement, death of a spouse, or loss of income-producing property. This is called a Life-Changing Event appeal, and it may lower your IRMAA for the current year, but the amounts you already paid remain non-deductible.

What you can deduct instead: the medical expense threshold

While Medicare premiums themselves are off-limits, other medical costs may be deductible if you itemize deductions and your total medical expenses exceed 7.5 percent of your AGI. This includes copays, coinsurance, deductibles, prescription costs not covered by insurance, dental work, vision care, and hearing aids.

To use this deduction, you must file IRS Form 1040 and Schedule A (Itemized Deductions). You add up all may have access to medical expenses for the year, subtract 7.5 percent of your AGI, and deduct the remainder. For most people, the standard deduction is larger than the medical expense deduction, so itemizing does not help.

Keep receipts and statements for all medical costs throughout the year. Medicare statements, pharmacy receipts, and doctor invoices all count. If you have significant medical expenses—such as ongoing treatment, surgery, or long-term care—tracking these costs carefully can make a real difference at tax time.

State and local tax treatment of Medicare premiums

Some states do not tax Social Security income, and a few states have special rules for retirees. However, these rules do not change the federal tax treatment of Medicare premiums. Even if your state does not tax Social Security, Medicare Part B premiums deducted from that income are still not deductible on your federal return.

A small number of states offer deductions or credits for health insurance premiums paid by low-income seniors, but these are rare and vary widely. Check your state's tax website or speak with a tax professional if you live in a state with special senior tax provisions.

Keeping records for tax time

Save your Medicare statements and any documents showing Part B premiums you paid during the year. If you have other medical expenses, keep receipts for those as well. Your Social Security statement shows if Part B was deducted from your benefits, and your Medicare Summary Notice (MSN) shows premiums paid.

If you are self-employed and claiming the self-employment health insurance deduction, keep records of all premiums paid and proof of self-employment income. The IRS may ask for documentation if you are audited.

When you file your taxes, do not attempt to deduct Medicare premiums on Schedule A or anywhere else on your return. If you are self-employed, the deduction goes on Schedule C only. If you are unsure whether you may have access to for the self-employed exception, consult a tax professional before filing.

Frequently Asked Questions

Can I deduct Medicare premiums if I pay them myself instead of having them taken from Social Security?

No. Whether you pay Part B premiums directly to Medicare or have them withheld from Social Security, the result is the same for tax purposes—they are not deductible. The method of payment does not change the IRS rule.

What if I have very high medical bills in addition to Medicare premiums?

Your other medical expenses may be deductible if they exceed 7.5 percent of your AGI, but Medicare premiums themselves never count toward that threshold. Add up copays, deductibles, prescription costs, and other out-of-pocket medical expenses separately from premiums.

I am self-employed and still working. Can I deduct my Medicare Part B premiums?

Yes, if you have net self-employment income. The deduction appears on Schedule C and reduces your taxable self-employment income. You cannot deduct more in premiums than you earned from self-employment in that year.

Does my state allow a deduction for Medicare premiums even if the federal government does not?

Most states follow federal tax rules and do not allow the deduction. A few states have special provisions for low-income seniors, but these are uncommon. Check your state's tax website or contact a tax professional in your state to be certain.

If I appeal my IRMAA and it gets lowered, can I deduct the overpayment?

No. IRMAA amounts are not deductible whether you pay them or not. If Medicare lowers your IRMAA after an appeal, you may receive a refund or credit toward future premiums, but you cannot deduct the amount you already paid.
