It is certainly possible. The MS earning (or yearly earnings plus MS earnings) would have to be greater than one of the years used for computing SS benefits. Some people have reported very low wages, and for them, a really good MS year might be enough to replace a low wage year. I am curious to see if anyone has been able to attribute an increase solely to MS income. Of course, it has to be net income, not gross income. The only chance is for people who do not reach the maximum yearly income which is subject to SS tax who have lower years to replace. In 2019, that is $132,900 in 2019 , up from $128,400 in 2018. It is very complicated, because earlier basis year income is indexed for inflation.
