SSA-44 FAQs

What events qualify for Form SSA-44?

SSA lists marriage, divorce or annulment, death of a spouse, work stoppage, work reduction, loss of income-producing property, loss of pension income and an employer settlement payment.

Does a Roth conversion or stock sale qualify by itself?

A one-time income spike alone is not one of the listed SSA-44 life-changing events. A separate qualifying event that reduced household income may still support a request.

What if an amended tax return lowered my MAGI?

SSA directs beneficiaries with an amended income-tax return to contact SSA. That situation is handled outside the ordinary online life-changing-event flow.
