In addition, the FERCCA allows certain employees who have completed a schedule of make-up contributions, or who plan to schedule make-up contributions, to receive lost earnings on those contributions under certain circumstances. Employees are (and have been) entitled to lost earnings on the make-up agency contributions they receive as a result of the correction of an agency error.","path":["Title 5—Administrative Personnel","CHAPTER I—OFFICE OF PERSONNEL MANAGEMENT","SUBCHAPTER B—CIVIL SERVICE REGULATIONS","PART 839—CORRECTION OF RETIREMENT COVERAGE ERRORS UNDER THE FEDERAL ERRONEOUS RETIREMENT COVERAGE CORRECTIONS ACT","Subpart J—Lost Earnings for Certain Make-up Contributions to the TSP"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-5.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:23:53Z","sha256":"d3bfeef2fe86b7a58eb04df83f8daea8fb006a2bbd0951774f363365465431e2","source_id":"us-cfr","stale":true,"prev":"us/5-cfr-839.903","next":"us/5-cfr-839.1002"},"notice":"GroundRules: Original legal text.
