I’m 80 still working and paying into SS , but I see no raise in my check

Hi. 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. Without access to your full Social Security covered earnings history I have no way of knowing whether or not your recent earnings were high enough to increase your benefit rate. However, you can submit a written and signed request to Social Security requesting a benefit recomputation if you believe that your recent earnings were high enough to make you eligible for a higher rate.

Best, Jerry
