Medicare IRMAA FAQs – Tax deductions, duration, and how to pay

For higher income retirees, Medicare adds a surcharge to your Part B and Part D premiums, called IRMAA, or the Income Related Monthly Adjustment Amount. The extra charge is determined by your Modified Adjusted Gross Income, and there are a couple important questions we’re often asked:

We have several other articles that go into detail about various aspects of IRMAA, including:

In this article, we are just going to cover some common questions that we recieve about IRMAA that can be answered without knowing a lot about your personal financial situation.

Is IRMAA Tax Deductible?

Yes, IRMAA surcharges are deductible as part of the medical expense deduction (as are other Medicare expenses). But, because of the relatively high standard deduction today, few taxpayers itemize their deductions and qualify for this.

If you do itemize on your taxes, you are able to deduct any medical and dental expense for you, your spouse, and your dependents that exceed 7.5% of your AGI, or Adjusted Gross Income. If your Medicare expenses, along with out of pocket expenses for medical and dental care exceed 7.5%, you may be able to take advantage of this and recieve a tax deduction based on your Medicare surcharge.

How Long Does IRMAA Last?

Your surcharge is determined each year, so if you’re only high income for one year, it will eventually be reduced in a future year. Typically, you will be notified by the Social Security Administration in November or early December if you will be subject to the Medicare surcharge for the next year.

There’s a two-year lookback for the charge. So your 2025 Medicare premium will be based on your 2023 income. Your 2026 Medicare premium would be based on your 2024 income.

For example, if you had very high income in 2023 due to a work bonus, sale of a rental property, Roth conversion, or large IRA withdrawal, that will only impact your 2025 Medicare premium. It will not impact you for the rest of your life as long as your income drops in future years.

How is IRMAA Billed?

If you have started your Social Security benefits, you will pay the Medicare surcharge through your monthly Social Security payment. You will recieve a reduced net amount into your bank account each month as the Medicare premiums and surcharges are withheld.

If you have not begun your Social Security benefits yet, you may also pay via direct bill, as part of your regular Part B and Part D payment on a quarterly basis.
