Intra-governmental Transactions

Intra-governmental Transactions (IGT)

As federal entities conduct business with each other, IGT activity must follow standard processes that support the recording, reporting, reconciliation, and measurement of intra-governmental activity. Federal entities’ adherence to the process provides the required controls for IGT activity and allows both federal entities, and Fiscal Service, to perform their financial statement reporting in an efficient way.

Two of the applications used by federal entities in the brokering of IGT transactions between two federal trading partners are G-Invoicing and Intra-governmental Payment and Collection (IPAC). More information about those applications is provided below.

G-Invoicing

G-Invoicing is the long-term solution for federal entities to manage their intra-governmental (IGT) Buy/Sell transactions. G‑Invoicing helps (or will help) agencies and their trading partners:

  • Negotiate and accept General Terms and Conditions (GT&C) agreements
  • Broker orders
  • Exchange performance information
  • Validate settlement requests through IPAC

Federal entities were mandated to implement G-Invoicing for New Orders by October 2022. The mandated implementation deadline of October 2022 for New Orders includes Orders with a Period of Performance beginning October 1, 2022 or later.

Federal entities must submit quarterly implementation status updates to Treasury by providing updated plans and/or Attachment As and/or Attachment Bs to the IGT mailbox (IGT@fiscal.treasury.gov). These templates are located on our G-Invoicing Resources page.

Treasury will help agencies get ready for and start using G-Invoicing. (See more on the Enrollment page.)

Benefits of G-Invoicing

Better communication between trading partners: Using G-Invoicing to communicate, trading partners share a common platform and a clear record of their negotiations.

Transparency: G-Invoicing supports each phase of the IGT Buy/Sell lifecycle. This common repository will decrease differences between agencies.

Common data standard: G-Invoicing replaces the various terms and forms that agencies have historically used to broker their Agreements.

Agreed-upon processes: Common processes support timely and accurate accounting.

Streamlined settlements of funds in IPAC: With performance reporting in G-Invoicing, trading partners can settle more quickly and efficiently.

Intra-governmental Transactions Working Group (ITWG)

ITWG Meetings are 90 minute conference calls that focus on data attributes, process flows, and system interface specifications for G-Invoicing. Topics are provided before the meetings to ensure that all ITWG participants with knowledge on the topic join the meeting.

To join the ITWG Working Group, send an e-mail to IGT@fiscal.treasury.gov.

Our ITWG meeting materials are now available in Intralinks. Access to Intralinks can be requested through the Treasury Support Center (Email: GInvoicing@stls.frb.org or Phone: 1-877-440-9476)
