DATE: Monday, March 16, 2026
In March and September each year, the IBC is required to provide a Semiannual Headcount Report to the Office of Personnel Management (OPM) on behalf of our customer agencies. The report provides OPM a snapshot of the monies withheld from salaries for participation in the Civil Service Retirement System, Federal Employees Retirement System, Federal Employees Health Benefits Program, and the Federal Employees' Group Life Insurance Program. OPM uses this information when negotiating premium rates and employer contributions for health benefits and life insurance.
Per OPM's Benefits Administration Letter 26-305, the March 2026 Headcount Report is due March 31, 2026. The Payroll Operations Division reconciles, validates, and submits the report to OPM – our customer agencies are not required to take any action. If you would like a copy of the report for informational purposes only, please contact Michelle Blackmon, Supervisory Accountant, Review and Analysis Branch, at Michelle_D_Blackmon@ibc.doi.gov or 303-969-5649.
Additional information about the Semiannual Headcount Report can be found in Chapter 4.7 of the Payroll Accounting Guide.
