Understanding Medicare IRMAA
What Higher-Income Retirees Need to Know
When enrolling in Medicare, most people expect to pay the standard Part B premium. However, if your income exceeds certain thresholds, you may pay more due to IRMAA, the Income-Related Monthly Adjustment Amount.
Understanding how it works, and planning ahead, can potentially save thousands in retirement.
💡 What Is IRMAA?
IRMAA is an additional premium added to:
- Medicare Part B (Medical Insurance)
- Medicare Part D (Prescription Drug Coverage)
It applies if your Modified Adjusted Gross Income (MAGI) from two years prior exceeds specific limits.
👉 Your 2026 premiums are based on your 2024 tax return.

⚠️ Client Alert: Just $1 Over the Line Can Cost You
If your income exceeds a threshold by even $1, you move into the next IRMAA tier and pay the higher premium for the entire year.
For example:
- Standard Premium: $202.90
- Highest Tier Premium: $689.90
- Difference: $487 per month
- Annual Difference: $5,844 per person
For married couples, that could mean nearly $12,000 per year in additional Medicare costs.
🧠 Why IRMAA Catches Retirees Off Guard
Many people unintentionally trigger IRMAA due to:
- Large IRA withdrawals
- Required Minimum Distributions (RMDs)
- Roth conversions
- Sale of a business or property
- Capital gains
- Widowhood (switching to single filing status)
- One-time income events
Because Medicare uses a two-year lookback, the impact often surprises retirees long after the income spike occurred.
📉 Can IRMAA Be Appealed?
Yes.
If your income dropped due to a qualifying life-changing event (retirement, divorce, death of spouse, etc.), you may file Form SSA-44 to request a reduction.
Many retirees do not realize they qualify.
🎯 Planning Tip:
IRMAA is not just a Medicare issue.
It is a tax and income-planning issue.
Strategic decisions about:
- Roth conversions
- Timing of Social Security
- Capital gains realization
- Distribution sequencing
- Charitable giving strategies
can directly impact whether you cross IRMAA thresholds.
