Q: In 1975 I entered Federal employment under CSRS. then resigned in 1981, and withdrew my retirement contributions. I re-entered fed employment in 1984 under CSRS Offset and transferred to FERS in 1987, then resigned and withdrew my retirement contributions. I later re-entered fed employment in 1994 under FERS. I have paid back all retirement withdrawals allowed, plus interest. When my retirement is calculated over 30 years in service, will my CSRS Offset time be added to the CSRS years, or the FERS years?
