An IRMAA appeal asks Social Security to lower or remove the income-based surcharge on your Medicare Part B and Part D premiums, and it costs nothing to file. Appeals succeed in exactly two situations: a qualifying life-changing event — retirement is the most common — has reduced your income since the tax year Social Security used, or the tax information they used was wrong or outdated.

If your income dropped or a life event changed your situation, this kit walks you through the appeal step by step. It includes the SSA-44 walkthrough, evidence lists, letter templates, and a worksheet.
The long answer
Here’s the structural fact behind most successful appeals: the surcharge is set by your tax return from two years earlier, so 2026 premiums reflect 2024 income. If you have retired, been widowed, or divorced since that return was filed, it may describe a life you no longer have — and the appeal exists to substitute your income as it is now.
The life-changing-event path uses Form SSA-44, a few pages filed with Social Security along with evidence: proof the event happened and documents supporting your estimate of this year’s income. Qualifying events include work stoppage, work reduction, marriage, divorce or annulment, the death of a spouse, loss of pension income, loss of income-producing property, and certain employer settlement payments.
What an appeal cannot do is undo a surcharge based on income you genuinely had. A one-time windfall — a Roth conversion, a business sale — was real income, and the surcharge on it stands; that situation corrects itself the following cycle, when a more normal return takes over. If your appeal is approved, your premium is corrected going forward and the extra amounts already collected that year come back. If it is denied, you have 60 days to request reconsideration.
You can file Form SSA-44 as soon as the qualifying life-changing event happens. You do not have to wait for the IRMAA determination letter, and filing early can prevent months of overcharge instead of forcing you to recover them later. The standard Part B premium itself, $202.90 a month in 2026 according to CMS, cannot be appealed. Only the IRMAA surcharge can. Social Security does not reduce IRMAA just because the amount feels high. The appeal has to be based on a qualifying life-changing event or wrong tax data.
