2024 IRMAA Cost Sharing for Higher Income Medicare Beneficiaries

Higher income Medicare beneficiaries pay more for Medicare Part B and Part D premiums. Called an Income-Related Monthly Adjustment Amount (IRMAA), this added fee is added to your monthly premium costs. In 2024, individuals whose income is higher than $103,000 and married couples who file taxes jointly whose income is more than $206,000 will pay the IRMAA surcharge. Married couples filing separately pay more.

How is IRMAA Calculated?

IRMAA applies only if your annual Modified Adjusted Gross Income (MAGI) exceeds the threshold amount set each year by the Social Security Administration (SSA). It is calculated using your MAGI from your taxes two years ago. In 2024, your IRMAA will be based on your 2022 tax return. 

If you have to pay the IRMAA surcharge in 2024, you should have received a Notice of Initial Determination from the SSA. The notice states your new premium amount and the reason for the determination. 

Can I Request a New IRMAA Determination?   

Yes, but you have to have a qualifying reason, such as:

  • Your tax return is out of date or you filed an amended return the year the SSA is using, so 2022 for the 2024 coverage year
  • There was an error in the IRS data
  •  You had a major, life-changing event that significantly reduced your income

IRMAA Qualifying Life-Time Events

There are 7 qualifying life-changing events:

  1. Your spouse died
  2. You got married
  3. Your got divorced or had your marriage annulled
  4. You or your spouse reduced the number of hours worked
  5. You or your spouse stopped working
  6. You involuntarily lost income from an income-producing property (for example,  (from a natural disaster, disease, or fraud)
  7. You lost or had certain kinds of pension income reduced

You can request a lower IRMAA, you will need to complete the Medicare Income-Related Monthly Adjustment Amount-Life-changing Event (SSA-44) and email or fax it to your local SSA office. Find your local SSA Office. You can also call the SSA at 800.772.1213. 

Can I Appeal My IRMAA New Initial Determination? 

If you disagree with the SSA’s IRMAA decision, but do not qualify to request a new initial determination, you can file an appeal, called a reconsideration. The SSA does not have a required time frame to respond to your request. If you have questions about your appeal status, contact the agency currently reviewing your appeal.

If your reconsideration is denied, you can appeal to the Office of Medicare Hearings and Appeals (OMHA) level within 60 days of the date on the reconsideration denial determination.
