Why is my Part B premium higher than my neighbor’s?

Probably IRMAA — an income-related amount Social Security adds to Part B and Part D premiums when your income two years ago was above a threshold. It is based on an old tax return, so people who just retired often pay it on income they no longer have. If your income dropped because of a life-changing event — retirement, loss of a spouse, divorce, reduced work — you can file form SSA-44 and ask Social Security to use this year’s income instead.

If your income was above a threshold two years ago, Social Security adds an income-related amount (IRMAA) to your Part B and Part D premiums. If your income has since dropped because of a life-changing event — retirement, loss of a spouse, divorce, reduced work — you can ask Social Security to use your current income instead, using form SSA-44.

Who this is for

People whose Part B premium notice shows an income-related amount.

What changes it

  • A drop in income without a qualifying life-changing event usually has to wait for the normal two-year cycle.

The question that settles it

“My income dropped because of [event]. Can I file SSA-44 to lower my Part B premium?” — Social Security.
