Intra-Governmental Payment and Collection

All IPAC transactions, whether submitted manually or via bulk file, must be fully processed in the IPAC system before 11:59 PM (EST) on September 30, 2021 to be dated as FY21. Any transactions not fully processed until 12:00 A.M. (EST) or after on October 1, 2021 will be dated as FY22.

Bulk files, for example, could possibly take a couple of hours to process to completion so please allow sufficient processing time when submitting any IPAC transactions at year-end. We advise agencies to obtain confirmation within IPAC that the bulk file has completed successfully before the end of the accounting period cutoff.

Per the TFM for Buy/Sell transactions, Volume 1 Part 2 Chapter 4700 Appendix 8, "Treasury has established an IPAC cutoff date that requires all IPAC Buy/Sell transactions to be successfully processed no fewer than three business days before the close of each month or five business days before the close of year-end reporting."

Please call the Treasury Support Center at 877-440-9476 or email if you have any questions.

IPAC is a way for Federal Program Agencies (FPAs) to transfer funds from one agency to another with standardized descriptive data.

IPAC has three components:

  • IPAC
  • Retirement and Insurance Transfer System (RITS)
  • Treasury Receivable Accounting and Collection System (TRACS)
