Updated July 28, 2026. Quick answer: You cannot appeal it away. SSA’s own operational guidance names “Conversion of an IRA” in its enumerated list of events that do NOT qualify for relief. The regulation lists exactly seven life-changing events and a companion provision makes that list exclusive. A conversion is a voluntary act, and voluntary acts are the thing the relief is designed not to cover.
The seven events, and what is missing from them
20 C.F.R. §418.1205 lists the qualifying events, and §418.1210 makes the list exclusive. They are all things done to you rather than by you — marriage and its endings, the death of a spouse, work stoppage or reduction, loss of income-producing property, loss of a pension, and an employer settlement payment.
| Event | Qualifies? |
|---|---|
| Death of a spouse, divorce, marriage | Yes |
| You stopped or reduced work | Yes |
| Loss of income-producing property outside your control | Yes |
| Roth conversion | No — named as non-qualifying |
| Selling a business or property | No |
| A large capital gain | No |
| A required minimum distribution | No |
The planning error this creates is expensive and common. A conversion is recommended, the IRMAA consequence is raised, and someone says “you can file an SSA-44 afterwards.” You cannot — not for the conversion. The surcharge arrives two years later and is simply owed. The IRMAA cost has to be priced into the conversion decision at the time, because there is no remedy afterwards.
And because IRMAA is a cliff, the cost of a conversion that crosses a boundary by a small amount is the same as one that crosses it by a lot.
No dollar thresholds appear here. Most IRMAA bracket boundaries are CPI-indexed and change annually, and the top boundary is on a different schedule from the rest. Take the current year’s thresholds from CMS or the Social Security Administration directly.
