IRMAA life-changing events: the 8 that qualify

IRMAA is set from your tax return from two years ago. If one of these 8 events lowered your income since then, Social Security will use your newer, lower income instead. You ask with Form SSA-44.

Pick your event

What doesn't count

These raise your income, but Social Security turns them down on Form SSA-44:

Income changes that are not life-changing events
Not an eventWhy
A Roth conversionYour choice, not a life-changing event. The extra charge ends when that year's income stops being used, two years later.
Selling your home or other propertyA one-time gain from a sale you chose doesn't count, even if it pushed you into a higher bracket.
Capital gains or a large IRA withdrawalInvestment income you chose to take doesn't count.
Required minimum distributionsThey're expected income, not an event.
A one-time bonus or severanceOnly a settlement from an employer's bankruptcy or reorganization counts.

Two rules for every event

  1. Your income has to drop enough to change your bracket. Moving within the same bracket changes nothing. Check with the IRMAA bracket calculator.
  2. You need two kinds of proof: proof of the event (each event page lists what Social Security accepts), and proof of income for the year you ask them to use: a signed tax return, an IRS transcript, or your estimate for a year not filed yet.

Waiting for a document? You can still file

Social Security can record your proof as pending. You then have 30 days to send it, and you can ask for more time before the 30 days end.

Questions people ask

What is a life-changing event for IRMAA?

One of 8 events listed on Form SSA-44 that can lower your income: marriage, divorce or annulment, death of your spouse, work stoppage, work reduction, loss of income-producing property, loss of pension income, and an employer settlement payment.

Is retirement a life-changing event?

Yes. Retiring is a work stoppage. Use the month of your last day of work, not the month your pension or Social Security started.

How far back can the event be?

The event must have happened in or before the tax year you ask Social Security to use, and it must have lowered your income in that year. That year must be more recent than the one they used.

Does my spouse's event count for me?

For work stoppage and work reduction, yes: your spouse retiring or cutting back counts on your form. If both of you are on Medicare and pay IRMAA, each of you files your own SSA-44.
