Does GSA TDR Apply to Your Contract? How to Check Your Start Date

How to tell if monthly Transactional Data Reporting applies to your GSA MAS contract, how your start date is set, and where to confirm it.

Monthly Transactional Data Reporting (TDR) now applies across GSA’s Multiple Award Schedule. Here is how to see where your contract stands and when your first monthly report is due.

What GSA says about who is covered

GSA’s TDR page says: “Effective with Refresh 31, Transactional Data Reporting, or TDR, is mandatory for all Multiple Award Schedule SINs.”
GSA’s TDR User Guide says Refresh 31 “was released on April 2nd, 2026.”
GSA says this covers “all new MAS offerors and existing MAS contract holders.”
One exception: “TDR currently does not apply to VA Schedule contracts.”
Some contracts moved to TDR earlier. In August 2025 GSA said: “If you have any SINs that are TDR eligible, TDR participation is mandatory.”

How your start date is set

If your contract was not yet on TDR, the change comes through a contract modification.

GSA said a “Mass Modification to ‘Participate in TDR’ will be issued to all MAS contractors who have not yet transitioned.”
GSA’s Refresh 31 webinar says: “Contractors must accept this modification within 90 days of issuance.”
GSA’s Help with TDR page says: “MAS-TDR reporting begins on the first day of the quarter after acceptance of the TDR modification.”
Until then, “Non-TDR requirements will continue to apply until the effective date of the Participate in TDR modification.”

GSA asks existing contractors to accept the Refresh 31 mod first, then the TDR mod, “as soon as possible.”

When your first report is due

GSA says: “Reports are due within 30 calendar days after the end of each month.”
GSA’s webinar gives an example. A contractor accepts the mass mod on “4/15/2026.” TDR becomes effective on the “first day of next quarter (7/1/2026).” The contractor must “Submit July transactional data by August 30, 2026.”

Your own dates depend on when your mod was accepted.

How to check your own contract

Find your SINs. GSA says: “You can find awarded SINs by searching your contract number in GSA eLibrary search bar, then click on company name.”
Find your TDR mod. Look in your contract modification records for the “Participate in TDR” mod. GSA has said: “The effective date will be included on the approved Participate in TDR modification SF30.”
Check for a pending mod. GSA ties your start date to when you accept the TDR mod. If the mass mod is still waiting for your signature, accept it and note the quarter it starts.
Ask your Contracting Officer. GSA’s User Guide says “you can confirm your effective date with your MAS Contracting Officer if needed.”

Where to confirm: Your MAS Contracting Officer, GSA’s TDR page (gsa.gov/tdr) and GSA’s TDR team at TDRteam@gsa.gov.
