SUBJECT:  Early Submission of Time and Attendance (T&A) Files for Pay Period (PP) 2023-13

Juneteenth holiday, June 19, 2023, falls at a critical time in the payroll processing cycle for PP 2023-13. As a result of the holiday, all pay groups are required to submit amendment T&A files to the Interior Business Center (IBC) early as outlined below. Clients whose payroll normally calculates on Tuesday night (listed in the table below*), are also required to submit current T&A files early as outlined below. It is essential all timekeepers and data processing staff are advised of the importance of following the PP 2023-13 schedule detailed in this memo.

Below are the submission deadlines, 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.

Amended T&As

Amended T&As for all clients must be submitted/released no later than Friday, June 16, 2023.

Current T&As

  • Clients listed in the table below* whose payroll normally calculates on Tuesdays:
    • Current T&As must be submitted/released to the IBC early on Friday, June 16, 2023.
  • All other clients whose payroll normally calculates on Wednesdays:
    • Current T&As must be submitted/released on their normal schedule no later than Tuesday, June 20, 2023.

In order to ensure submissions are received early, it may require changes to release schedules from your T&A system. Agencies should inquire with their T&A system administrator to see if changes are needed.

For Quicktime or webTA, administrators will need to review and ensure the Lock/Release or Build and Transfer schedule is changed appropriately for early submission. Once payroll calculation has been completed, administrators will need to change the schedules back to normal scheduling.
