Service credit deposit for part-time work


Q: I need clarification of a fine point about calculating the amount of a service credit deposit for a four-month period of temporary service back in 1979 when no retirement deductions were withheld. I know that I would have to pay 1.3 percent of basic pay plus interest. My question relates to the definition of “basic pay.” Would basic pay be the pay I earned during the four months I was a temporary employee ($2,300), or would it be the annual pay rate for a person working at my grade in 1979 ($8,366)?

A: The deposit would be 1.3 percent of the basic pay you received, plus accrued interest.
