SUBJECT: Early Submission of Time and Attendance (T&A) Files for Pay Period (PP) 2024-02

Martin Luther King Jr. holiday, January 15, 2024, falls at a critical time in the payroll processing cycle for PP 2024-02. As a result of the holiday, all pay groups are required to submit amendment and current T&A files to the Interior Business Center (IBC) as outlined below, which may be early for some agencies. It is essential all timekeepers and date processing staff are advised of the importance of following the PP 2024-02 schedule detailed in this memo.

Below are the submission deadlines and important notes to follow, with T&A files required no later than 6:45 p.m. Mountain Time, or earlier, depending on the latest release allowed by your T&A solution:

All other agencies (normally calculates on Wednesday nights)Tuesday, January 16, 2024

Important notes: 

  • T/As must be submitted/released
  • It is imperative that all agencies complete personnel actions related to the retroactive pay adjustments that have implications related to amended and current T&A processing such as separation, deceased, leave without pay status, etc.

To ensure submissions are received early, it may require changes to release schedules: 

  • Non-IBC supported T&A solutions:
    • Agencies should inquire with their T&A system administrator to see if changes are needed. 
  • IBC supported T&A solutions:
    • Quicktime or webTA, administrators must review and ensure the Lock/Release or Build and Transfers schedule is changed appropriately for early submission. 
      • Once payroll calculate has been completed, administrators must change the schedules back to normal scheduling.
