GSA Transactional Data Reporting
TDR is a monthly report of what you actually sold under your GSA contract — line by line, in a fixed file format, twelve times a year.
Where the requirement comes from
The clause is GSAR 552.216-75, Transactional Data Reporting (May 2023 version), prescribed at GSAM 516.506(c). It is in your contract. With MAS Solicitation Refresh 31, published 2 April 2026, TDR applies across all MAS Special Item Numbers, effective 1 July 2026. Before that it was a voluntary pilot on selected SINs.
What you report
Each transaction under the contract, as its own line: what was sold, the SIN it falls under, the quantity, the price per unit, the total, the order it came from, the date, and who bought it. For a reseller with a few hundred order lines a month, that is a few hundred rows.
When
Within 30 calendar days after the last calendar day of the reporting month. July's data is due by 30 August. A month with no sales still needs a report — the zero-sales filing is the one people most often miss.
How it is submitted
Through the FAS Sales Reporting Portal at srp.fas.gsa.gov, which takes an Excel file
upload, keyed entry in a form, a CSV upload, or an API/EDI feed. Sign-in needs a digital certificate
and multi-factor authentication. Most contractors use the
Excel upload.
What happens if you do not file
There is no fine attached to the clause. The consequence is contractual: it goes to your Contracting Officer, and it can affect whether an option period is exercised, or whether the contract continues at all. For a small vendor that is the whole federal revenue line, which is why it is worth more attention than the size of the task suggests. GSA's enforcement grace period runs to 31 December 2026.
The Industrial Funding Fee
Separately from the report, you remit the Industrial Funding Fee — 0.75% of reported sales, quarterly, under GSAM 538.270-1. Reporting and remitting are two different obligations on two different clocks.
