If you’re among the approximately 8% of Medicare beneficiaries paying a surcharge on top of your standard Part B premium, you’re probably wondering why this is happening and what you can do about it. The good news is that in certain circumstances, you may be able to reduce or eliminate these additional costs through an appeal process. This comprehensive article will walk you through everything you need to know about IRMA and how to navigate the appeal system.
What Is IRMA?
IRMA stands for Income-Related Monthly Adjustment Amount. It’s a surcharge that higher-income Medicare beneficiaries must pay in addition to their standard Part B and Part D premiums. Think of it as a progressive pricing structure for Medicare—similar to how our tax system works, those with higher incomes pay more for their Medicare coverage.
For 2026, the standard Part B premium is $202.90 per month. However, if your income exceeds certain thresholds, you’ll pay this base amount plus an additional IRMA surcharge, which can significantly increase your monthly costs.
How IRMA Is Calculated
One of the most important things to understand about IRMA is the timing involved. Your 2026 IRMA surcharge is based on your Modified Adjusted Gross Income (MAGI) from two years prior—specifically, your 2024 tax return. This two-year lookback period is critical because it means your current income may be very different from what Medicare is using to calculate your surcharge.
The Social Security Administration (SSA) determines your IRMA amount by reviewing tax return information provided by the IRS. They use your MAGI, which includes your adjusted gross income plus any tax-exempt interest income.
2026 Income Thresholds
For 2026, IRMA surcharges apply if your 2024 income exceeded:
- $109,000 for individual filers
- $219,000 for married couples filing jointly
These thresholds create multiple income brackets, with surcharges increasing at higher income levels. The additional amounts can range from around $80 per month at the lowest IRMA bracket to over $400 per month at the highest income levels—and that’s just for Part B. If you have Part D prescription drug coverage, you’ll face additional IRMA surcharges there as well. See the 2026 IRMA Brackets
Why You Might Qualify for an Appeal
Here’s where it gets interesting: because Medicare uses two-year-old income data, many beneficiaries find themselves paying IRMA surcharges based on income they’re no longer earning. This is especially common for recent retirees who had high W-2 income in their final working years but now live on significantly less.
You can appeal your IRMA determination if you’ve experienced what Medicare calls a “life-changing event” that has reduced your income. Qualifying life-changing events include:
- Retirement or reduced work hours: You’ve stopped working or significantly reduced your employment
- Loss of income-producing property: Such as selling a rental property or business
- Loss or reduction of pension income: Your pension payments have decreased or stopped
- Death of a spouse: Especially relevant as this changes your filing status and household income
- Marriage: Your combined household income may be different than your individual income was
- Divorce or annulment: Your income situation has fundamentally changed
The key requirement is that the life-changing event resulted in a significant reduction in your Modified Adjusted Gross Income.
How to Appeal IRMA: Step-by-Step Process
If you believe you qualify for an appeal, here’s how to proceed:
Step 1: Obtain Form SSA-44
The official form for requesting reconsideration of your IRMA determination is Form SSA-44, titled “Medicare Income-Related Monthly Adjustment Amount – Life-Changing Event.” You can:
Step 2: Gather Supporting Documentation
Strong documentation is essential for a successful appeal. Depending on your life-changing event, you may need:
- For retirement: A letter from your employer stating your retirement date, your final pay stub, or documentation showing reduced work hours
- For loss of income-producing property: Closing documents from a property sale or business dissolution papers
- For divorce: Your divorce decree and updated tax filing status
- For death of a spouse: Death certificate and documentation of your changed financial situation
- Tax documents: Your most recent tax return showing your current, lower income
The more comprehensive your documentation, the stronger your case will be.
Step 3: Complete the Form Thoroughly
Form SSA-44 asks you to:
- Identify which life-changing event you experienced and when it occurred
- Provide your estimated income for the current year (the year you want the IRMA adjustment to apply)
- Break down your income by source (wages, self-employment, investments, etc.)
- Explain how the life-changing event reduced your income
Be as accurate and detailed as possible. If you’re unsure about exact amounts, use reasonable estimates based on your year-to-date income and expected income for the remainder of the year.
Step 4: Submit Your Appeal
You can submit your completed form and supporting documentation:
- In person: At your local Social Security office (consider making an appointment to avoid long waits)
- By mail: Send it to your local Social Security office
- Download- Go to SSA.gov, click on the Medicare tap and then request to lower IRMA
Keep copies of everything you submit for your records.
Step 5: Wait for a Decision
Social Security typically processes IRMA appeals within 30 to 60 days, though processing times can vary. You’ll receive a written decision explaining whether your appeal was approved or denied.
If approved, your reduced IRMA amount will typically apply for the current year and future years, as long as your income remains at the lower level. You may also receive a refund if you’ve already paid higher premiums.
Step 6: If Denied, You Can Appeal Further
If your initial appeal is denied and you believe the decision was incorrect, you have the right to request a formal hearing before an Administrative Law Judge. Instructions for this next level of appeal will be included in your denial letter.
What If You Don’t Qualify for an Appeal?
If you haven’t experienced a qualifying life-changing event but your income has decreased, you’ll need to wait for the two-year lookback to catch up with your current situation. For example, if your income dropped in 2025 but not due to a life-changing event, your IRMA surcharge will automatically adjust starting in 2027 when SSA reviews your 2025 tax return.
The Bottom Line
IRMA surcharges can add hundreds of dollars per month to your Medicare costs, but you don’t have to accept these charges if your financial situation has genuinely changed. Understanding the appeal process and gathering strong documentation can help you successfully reduce your Medicare premiums and keep more money in your pocket during retirement.
If you’re paying IRMA and have recently retired or experienced another major life change, it’s absolutely worth taking the time to file an appeal. The potential savings over the course of a year—or many years—can be substantial, making the effort well worthwhile.
