No. Once an employee is correctly placed under FERS (except those employees who were erroneously put in CSRS/Offset and were already corrected to FERS), the individual will always have FERS coverage in the future, unless excluded from retirement coverage because of the nature of the appointment.
If you currently work for the Federal Government, you should contact your Human Resources office for help. Your agency has all of your employment records and can verify whether your retirement coverage is correct. Please don't contact OPM as we normally don't receive your employment records until you separate from the Government.
If you are a separated employee, retiree, or survivor of an employee who was in the wrong retirement plan, contact OPM on 1-888-767-6738.
When your agency corrected your retirement coverage to FERS, it also should have contributed make-up agency contributions and lost earnings on those contributions to your TSP account.
If you now choose CSRS Offset, no adjustments will be made to your TSP account. Instead, OPM will find out how much of your TSP account is based on what your agency contributed (this includes the earnings on those contributions). That dollar amount will form the basis for an actuarial reduction in your CSRS Offset retirement benefit.
