Most seniors cannot deduct Medicare Part B premiums on their federal income taxes

Medicare Part B premiums are not tax-deductible for most people who pay them out of pocket. The IRS does not allow you to subtract Part B premiums from your taxable income, even though you pay them directly to Medicare each month. This is true whether you pay the standard premium or a higher amount based on your income.

The one exception is narrow: if you are self-employed and pay Part B premiums yourself (not through an employer), you may be able to deduct them as a business expense on Schedule C. This is different from the standard medical deduction and applies only to self-employed individuals before they reach age 65 and enroll in Medicare.

Key Takeaways

  • Part B premiums cannot be deducted from your federal income tax return for most retirees, even if you pay them yourself.
  • Self-employed people under 65 who pay their own health insurance premiums (before Medicare) may deduct Part B premiums as a business expense on Schedule C.
  • Part B premiums are not the same as out-of-pocket medical expenses, which may be deductible under different rules if they exceed a certain threshold.
  • Income-related monthly adjustment amounts (IRMAA) — the extra charges some higher-income seniors pay — also cannot be deducted.

Why Part B premiums are not deductible

The IRS treats Medicare Part B premiums as a personal expense, not a medical expense you can deduct. This is because Medicare is a form of insurance, and insurance premiums in general are not tax-deductible for individuals. The rule applies to Part B specifically, even though you must enroll in it at 65 or face penalties.

This differs from some other health insurance premiums. For example, if you are still working and your employer deducts health insurance from your paycheck before taxes, that amount is already excluded from your taxable income. But once you are on Medicare and paying premiums directly, the IRS does not allow you to deduct them later.

When you might deduct health costs related to Medicare

While Part B premiums themselves are not deductible, other medical expenses may be. If your total out-of-pocket medical costs — including Part B premiums, Part D prescription drug premiums, Medigap premiums, copays, coinsurance, and other unreimbursed medical expenses — exceed 7.5% of your adjusted gross income (AGI), you can deduct the amount above that threshold on Schedule A.

For example, if your AGI is $50,000, the threshold is $3,750. If your total medical expenses for the year are $5,000, you could deduct $1,250 (the amount over $3,750). Part B premiums count toward this total, but only as part of the larger calculation. You must itemize deductions on your tax return to use this rule; most seniors take the standard deduction instead.

Part D premiums (for prescription drug coverage) and Medigap premiums (supplemental insurance) also count toward this medical expense threshold, even though they are not deductible on their own.

Income-related charges and taxes

Some seniors pay higher Part B premiums because of their income. These extra charges are called Income-Related Monthly Adjustment Amounts (IRMAA). If your income is above certain thresholds, Medicare charges you more for Part B and Part D coverage. These IRMAA charges also cannot be deducted from your taxes.

IRMAA is based on your modified adjusted gross income (MAGI) from two years prior. For 2024, if your MAGI exceeds $97,000 (single) or $194,000 (married filing jointly), you will pay more. The extra amount increases with income. Like the standard Part B premium, IRMAA charges are not tax-deductible, though they do count toward the 7.5% medical expense threshold if you itemize.

What documents you need if you itemize deductions

If you decide to itemize deductions and include medical expenses, keep records of all Part B premium payments for the year. Your Medicare statements show what you paid each month. You will also need receipts or statements for any other medical expenses you are including — copays, prescription costs, dental work, vision care, or other out-of-pocket medical bills.

Form 1040 Schedule A is where you list itemized deductions, including medical expenses. You calculate the total of all medical expenses, subtract 7.5% of your AGI, and enter the remainder. The IRS may request documentation if you are audited, so keep your Medicare statements and medical receipts for at least three years.

Comparing itemizing versus the standard deduction

Most seniors take the standard deduction rather than itemize. For 2024, the standard deduction is $29,550 for married couples filing jointly and $14,775 for single filers age 65 and older. You would only benefit from itemizing if your total itemized deductions — including medical expenses, state and local taxes, mortgage interest, and charitable donations — exceed the standard deduction for your filing status.

Because the medical expense threshold is 7.5% of your AGI, you need very high medical costs to make itemizing worthwhile. If your AGI is $60,000, you must have more than $4,500 in medical expenses before you can deduct any of them. For most retirees, the standard deduction is the better choice.

Questions to ask your tax preparer or the IRS

If you are unsure whether you should itemize or take the standard deduction, a tax preparer can calculate both options and show you which saves more money. You can also contact the IRS directly at 1-800-829-1040 (TTY 1-800-829-4059) to ask about your specific situation.

If you are self-employed and still working before age 65, ask your tax preparer whether you can deduct health insurance premiums (including Part B if you have enrolled early) on Schedule C. This is a different rule from the standard deduction and may explore to your situation.

Frequently Asked Questions

Can I deduct my Medigap or Part D premiums?

No, Medigap and Part D premiums are not deductible on their own, just like Part B premiums. However, they do count toward the 7.5% medical expense threshold if you itemize deductions on Schedule A. You would need total medical expenses above that threshold to benefit.

What if my employer still pays part of my Medicare premiums?

If your former employer or current employer pays any portion of your Part B premium, that amount is not taxable income to you and you do not report it. You only report and potentially deduct the premiums you pay yourself.

Does my Part B premium count toward my out-of-pocket maximum?

No. Your Part B premium is separate from your out-of-pocket costs under Medicare. The out-of-pocket maximum applies to copays and coinsurance for covered services, not to premiums.

Can I deduct Medicare premiums if I am still working?

If you are still employed and your employer deducts health insurance from your paycheck, that amount is already excluded from your taxable income. If you pay Part B premiums yourself while working, they follow the same rules as for retirees — not deductible on their own, but they count toward the 7.5% medical expense threshold if you itemize.

Should I keep my Medicare statements for tax purposes?

Yes. Keep your Medicare statements showing Part B premiums paid for at least three years. If you itemize deductions, you will need them to calculate your medical expense deduction. The IRS may request documentation during an audit.
