When an adult has no current-year earnings and no future earnings and as long as you don't have a pension from non-covered earnings, you can enter your Social Security Retirement benefit that you would receive at age 70. Otherwise, in order to determine the best strategy for claiming benefits, MaxiFi and MMSS need to know an individual's 35 years with the highest covered earnings. It is not possible to determine whether the current year's or a future year's covered earnings will exceed a past year's earnings without actual past earnings. And if there is a pension from a job where there were non-covered earnings, no SS tax, then the full earnings record is needed to calculate the impact of GPO/WEP.
