TSP Eligibility Code Field Instruction

TSP Eligibility Code

Select the code that identifies whether or not a Federal Employees Retirement System (FERS), Civil Service Retirement System, Offset, or FERS employee is eligible to participate in FERS from the drop-down list. For a list of valid codes, see the TSP Eligibility Table. For detailed information regarding Thrift Savings Plan (TSP), refer to publications and bulletins published by the Federal Retirement Thrift Investment Board.
‎The TSP Eligibility Code is automatically changed to 9 when a TSP enrollment document is processed or when a FERS employee begins receiving the 1-percent Government basic contribution. Once Code 9 has been established, it cannot be changed. If an employee stops contributing, the employee’s eligibility to again contribute is determined by the Change Status Code and effective Date of Status Change fields in Information/Research Inquiry System Program IR118.
‎The Effective Date of Status Change is generated and is the first day of the pay period in which the Form TSP-1 is processed to begin employee contributions.
‎However, if the employee cancels the TSP contributions, the first day of the pay period in which the cancellation is processed will be generated as the Effective Date of Status Change. Note: The Effective Date of Status Change will not change if the employee elects to change the percentage rate or dollar amount of the contribution.
