For IRMAA purposes, a life-changing event is one of eight circumstances federal rules recognize: work stoppage (retirement), work reduction, marriage, divorce or annulment, the death of a spouse, loss or reduction of pension income, loss of income-producing property through events beyond your control, and an employer settlement payment tied to a bankruptcy or reorganization. If one of these reduced your income, Form SSA-44 asks Social Security to set your Medicare surcharge from your current income instead of the two-year-old tax return that triggered it.

It walks through Form SSA-44 step by step — the evidence Social Security wants for each event, and a worked example.

The long answer
The list exists because of a timing problem. IRMAA — the Income-Related Monthly Adjustment Amount — is calculated from your tax return two years back, so 2026 surcharges reflect 2024 income. For someone who retired, was widowed, or divorced in between, that snapshot is out of date, and the life-changing-event rules are the formal way to replace it with the way things actually are for you now.
By far the most common event is work stoppage — you retired, and the salary on the old return is gone. Each event pairs with natural evidence: an employer letter stating your last day, a death certificate, a divorce decree, a letter from the pension plan showing the stop or reduction.
Just as important is what’s not on the list: a one-time capital gain or Roth conversion, a required minimum distribution, a market decline, or the voluntary sale of property. None of those qualify — the income was real, or the loss isn’t the kind the rules count. The consolation is built in: one unusual year rolls out of the formula after a single cycle, no appeal needed.
