IRMAA FAQs Thumbnail


Social Security

We often receive IRMAA questions from clients and other people who visit our blog.  Below are a few of the most common questions.  As we see more questions, we will continue to update this page.  If you have a question, please share it with us and we will do our best to answer it!

1. What is IRMAA?

IRMAA, also known as the income-related medical adjustment amount.  Essentially, it’s a surcharge applied to Medicare premiums by the Social Security Administration for higher-income beneficiaries.

2. What parts of my Medicare premium are affected by IRMAA?

IRMAA applies to Medicare Parts B & D.  

3. Do I have to worry about IRMAA before I start taking Medicare?

No.  IRMAA only applies to Medicare beneficiaries.

4. Do I need to pay Part D IRMAA if I am not enrolled in Medicare Part D?

No.  According to a December 10, 2010 Centers for Medicare & Medicaid Services (CMS) memorandum, if an individual does not have a Medicare prescription drug plan, that person should not be charged Part D IRMAA.   However, if that person disenrolled (either voluntarily or involuntarily) and has unpaid Part-D IRMAA from the outstanding balance, then that person might be responsible for the past due amount.

5. Who decides my IRMAA, and how do they calculate it?

The Social Security Administration (SSA) makes this determination.  According to the SSA Program Operations Manual System (POMS) HI 01101.035-Initial IRMAA Determination Notices, the SSA makes these determinations based on IRS data (from your individual tax returns).

6. How do I pay IRMAA?

The SSA handles IRMAA payments in one of two ways:

  1. If you are taking Social Security and the amount of your check can cover your IRMAA charges, then the SSA will automatically deduct the IRMAA from your Social Security checks.
  2. If you are not yet taking Social Security, or the IRMAA charges exceed the amount of your check, then you will receive a bill for the unpaid IRMAA balance.  This bill will come from either the Centers for Medicare & Medicaid Services or the Railroad Retirement Board, whichever applies to you.

7. Do I have to pay IRMAA even if I’m not taking Social Security?

If you are a Medicare participant and subject to IRMAA due to income, then you are required to pay IRMAA even if you are not taking Social Security.

8. What are the IRMAA amounts for 2021?

The 2021 IRMAA surcharges will be calculated for most taxpayers using their 2019 MAGI (adjusted gross income plus municipal bond income).  The 2021 IRMAA surcharges are as follows:

2021 Medicare Part B IRMAA

According to the Centers of Medicare and Medicaid Services, below is the 2021 Medicare Part B IRMAA schedule.

Standard premium:   $148.50 per month (increase of $3.90 per month from $144.60 in 2020)

 9. What can I do if I don’t agree with my IRMAA determination?

There are several reasons you might not agree with the IRMAA determination.  The SSA provides clear online guidance in the case of two of them.

1. IRMAA determination based upon IRS tax information that is incorrect.  This could be based upon either an amended tax return for the year that was used for the IRMAA determination, or it could be based upon an IRS error.  In either case, the beneficiary will be expected to provide proof, through one of the following:

  1. An amended tax return
  2. A letter from the IRS documenting the factual data the IRS actually received & the erroneous information that the IRS provided to the SSA
  3.  A transcript from the IRS with new information and a copy of the filed tax return for the tax year the error occurred.

For more information on using corrected or updated tax information to determine IRMAA, you can refer to the POMS HI 01120.050-Use of Corrected IRS Tax Data or contact the SSA office.

2. You recently experienced a life event that either had or is expected to have a significant impact on your income.  The SSA recognizes 8 life-changing events that may be used to reduce or eliminate IRMAA:

  1. Death of a spouse
  2. Marriage
  3. Divorce or annulment
  4. Work reduction
  5. Work stoppage
  6. Loss of income-producing property
  7. Loss of employer pension
  8. Receipt of settlement payment from a current or former employer

If one or more of those events occurred, you may be able to request a reconsideration of your IRMAA based upon that event.  For that to occur, you would fill out Form SSA-44, Medicare Income-Related Monthly Adjustment Amount-Life Changing Event and provide the requested documentation.   This is not an appeal.  It is a request for the SSA to come to a new determination based upon information that they could not have assumed from your tax return.

If neither of these routes is effective in helping you, you can always appeal to the Office of Medicare Hearings and Appeals.  Before your appeal, you must have requested a reconsideration of the IRMAA determination.   

For more information, you can contact the SSA or start with the OMHA Medicare Part B Premium Appeals website.

10. What is SSA-44 and how does it affect my IRMAA?

As mentioned above, SSA-44 is the form you can use to request a new determination based upon life changes that have impacted your finances.  To help you, we’ve written a step-by-step guide to walk you through the SSA-44.

11. I received my IRMAA determination letter, but then I retired.  Can I ask Social Security to change my IRMAA?

Retirement is one of the 8 life-changing events that the SSA would consider when making a new IRMAA determination.  To do this, you would follow the instructions on the SSA-44 (see above).

12. Can Roth conversions help me avoid IRMAA?

When done as part of a deliberate Roth conversion strategy designed to reduce required minimum distributions (RMDs), Roth conversions can help you reduce or avoid IRMAA.  

However, each taxpayer’s situation is different, and there are many factors that might determine your taxable income, not just IRA distributions.  Some of these factors (not all of them) might include:

  • How much municipal bond income you receive (Line 2a on your Form 1040)
  • Whether you receive pension income
  • Other sources of income (part-time job, spousal income, etc).
  • Charitable contributions:  Charitable contributions can help decrease your taxable income, especially qualified charitable distributions (QCDs).  QCDs are charitable distributions that you can make directly from your IRA to the qualified charity of your choice.  QCDs can count against your RMD, and still not count as taxable income.
  • Capital gains-There are two types of capital gains worth considering
    1. Investments with low-basis, high capital gains-This might be stocks or mutual funds that you’ve accumulated over the years, either through an employer, family inheritance, or on your own.
    2. Capital gains distributions-This might be in mutual funds with high turnover.  Even if you don’t sell the mutual fund, the mutual fund manager may issue distributions at the end of the year based upon capital gains that the mutual fund has accumulated

13. It looks like the SSA used 3 year old information to calculate my IRMAA even though I have a more recent tax return on file.  What can I do?

It appears that this is a common occurrence.  In fact, it's common enough for the SSA procedure manual to have its own section that outlines what to do:  

HI 01120.055 Beneficiary Provides 2 Year Old Tax Data When SSA Used 3 Year Old Tax Data to Determine the IRMAA

To summarize, this is the process by which the SSA office should verify the taxpayer's more recent return, and use that information to re-run the IRMAA calculation.  For example, a client recently asked about her 2021 IRMAA, which was calculated using 2018 tax return information, even though she and her husband had filed a 2019 tax return.  

This should not require an SSA-44, because this is not considered a life-changing event.  This is a completely different procedural matter that requires a different process to resolve it.  

Update:  Recently, a client had this conversation with the SSA on this very matter.  It appears that something in the SSA's system is automatically generating a lot of these notices, which the SSA is trying to get fixed.  Two different SSA employees told her that in the interim, the best way to resolve this is to

  • Contact the SSA office to inform them of this
  • Resubmit the SSA-44 form.  If possible, put the form to the attention to the person/department you discussed this with

Your mileage may vary.  Will update this post as warranted.
