I began receiving SS benefits in 1992:but have continued to receive earned income subject to social security tax for the following 28 years. Does SS Administration recalculate my benefit to include my earnings in these subsequent years?

Hi. Yes. Social Security automatically recomputes Social Security retirement benefit rates when a person who's receiving benefits has an additional year(s) of earnings that are high enough to increase their benefit rate. But, Social Security retirement benefits are based on an average of a person's highest 35 years of Social Security covered wage-indexed earnings, so additional years of earnings only increase a person's benefit rate if they're higher than one or more of the 35 years currently being used to calculate the person's benefit rate.
