To understand the true cost of IRMAA, it helps to see the annual amounts you'll pay at each bracket level:
| IRMAA Tier | Monthly Part B | Monthly Part D | Annual Total | Annual Surcharge |
|---|---|---|---|---|
| Standard (No IRMAA) | $174.70 | $0.00 | $2,096.40 | $0 |
| Tier 1 | $244.60 | $12.90 | $3,090.00 | $993.60 |
| Tier 2 | $349.40 | $33.30 | $4,592.40 | $2,496.00 |
For married couples where both spouses are on Medicare, these amounts double. Understanding the annual impact is essential for comprehensive retirement planning.
Understanding what IRMAA stands for and how you reach a bracket is the first step. IRMAA is essentially a progressive surcharge on your income through Medicare — the more income you earn, the greater your surcharge.
You can file an IRMAA appeal if you've experienced qualifying life-changing events. Additionally, reducing your MAGI through strategic planning can help minimize surcharges.
