GSA TDR Due Dates, Zero-Sales Months and the 2026 Grace and Trial Periods

This guide describes GSA’s published instructions as of MAS TDR User Guide v2.0 (September 2026), as read on October 22, 2026; GSA updates them, so check its current pages before you report. It is not legal or tax advice.

Each monthly GSA TDR report is due within 30 calendar days after the month ends: October sales are due November 30. Every month counts, including a month with no sales, which you report as zero sales by Form Entry in the FAS Sales Reporting Portal (SRP), the only way SRP takes a month of $0 in sales. SRP takes the months in order, so a missed month is reported before the next one. The Industrial Funding Fee (IFF) runs on its own clock: it is due within 30 calendar days after each quarter, unless you choose to pay it monthly. GSA’s 2026 grace period (for contracts whose TDR effective date is on or after October 1, 2025) and its trial period (for six newer data fields, on every contract) both run from July 1 to December 31, 2026, and cover good-faith errors in the data fields only, never a missing report or a late fee. EG TDR Reporter shows the next report due, with the days left, on its Home page.

The monthly due date

GSA’s rule is 30 calendar days after the end of each month, and its own example is October sales due November 30. The clause behind TDR, GSAR 552.238-80 in the text acquisition.gov publishes (its Alternate I of May 2023; GSA’s own pages cite a December 2025 GSAR deviation of it), says the same, and SRP’s FAQs call it a 30-day window to report after the end of the month. Count the 30 days from the month’s last day:

Because the count runs from the month’s last day, a short February moves the January report into March: January 2027 sales are due March 2, 2027.

Which month a sale belongs to depends on your reporting basis. You report by invoice date or by payment date, whichever fits your accounting, and use the same one every month. So an invoice dated October 30 and paid November 12 is an October sale for a contractor who reports by invoice date, and a November sale for one who reports by payment date.

SRP’s FAQs say a month of zero sales must be reported within the 30-day period to avoid delinquency status. They also say that “all reports become delinquent once they have reached 30 days after the due date”, when SRP sends a data delinquency notification. Work to the 30-day date either way: it is the date GSA’s Help with TDR page and the clause give. The clause also names failing to submit the required reports as sufficient cause for the Government to terminate the contract for cause.

In EG TDR Reporter, Home shows the next report due with its contract, its due date (the month’s last day plus 30 days) and the days left, in amber when it is a week away and in red when it is late.

A month with no sales

A month without sales is still reported. The clause asks for a confirmation of no reportable transactional data within the same 30 calendar days, and SRP’s Data Reporting Options page says the only way to report $0 in sales is Form Entry, not a file. In SRP:

1. Choose Reporting, Form Entry, and pick the contract. SRP fills in the reporting period with the last outstanding month.
2. Choose Yes for zero sales.
3. Submit the report, tick the box that affirms the data is accurate, and confirm. The reporting status then reads Submitted.

The obligation runs to the end of the contract’s work: the clause asks for reports, zero months included, through physical completion of the last outstanding task order. SRP’s FAQs add that after a contract’s expiration date you report the months in which you have sales, not every month. If a month reported as zero later turns out to have had sales, it is corrected under Adjust Data, where you change the zero sales answer and upload the month’s file. Correcting a report covers it.

In EG TDR Reporter, a past month with no rows has a “No sales in” link on its Month page (No sales in August, for example). It asks whether you reported the month as zero sales in SRP, makes no file, and the Archive lists the month as “No file: zero sales (by Form Entry in SRP)”. If you run the checks on a month with no rows, the Block “No sales to report” says the same: report zero sales by Form Entry, then mark the month.

Missed months come first

SRP takes reports in chronological order. Form Entry fills in the last outstanding month and will not take a later month until every earlier one is reported, and a file upload that includes a contract with an earlier month unreported is rejected. If you are behind, report each missed month on its own, as zero sales where there were none, before the current month. Several contracts can share one upload file only when they are on the same reporting period.

EG TDR Reporter holds back a month’s file while an earlier month of the contract is neither reported nor has its file made, and warns when an earlier month’s file is made but not yet marked uploaded. If you reported earlier months in SRP before you started with the workbook, you set the first month you report in it on Setup, and the check starts there.

The IFF is due by the quarter

The fee has dates of its own. GSA requires the IFF to be remitted quarterly, within 30 calendar days after the last day of the quarter, and lets you pay monthly when you report if you prefer. SRP sends a reminder before the payment deadline. For each quarter:

The report for a quarter’s last month and that quarter’s IFF fall due on the same day: December 2026 sales and the October to December 2026 fee are both due January 30, 2027. The IFF guide covers the rate, how SRP figures the fee and how to pay it.

GSA’s 2026 grace and trial periods

GSA set two temporary periods to help contractors adapt to TDR. They cover different things and run over the same dates:

For a services contract, the trial period’s fields that apply are Federal Customer, UCID and Cloud Service Type. During both periods GSA will not take enforcement action for good-faith errors made when entering the required data fields. You may still receive system-generated compliance flags by email that point out discrepancies, and GSA expects you to use them to correct your data and your process. The relief covers the formatting and filling of data fields only, and it does not waive four obligations:

• reporting all sales every month, zero sales included;
• completing the required TDR data fields that apply;
• remitting the full and correct IFF on time;
• avoiding any intentional misrepresentation of sales data.

After December 31, 2026, your contracting officer can take enforcement action. Three more fields, order type, worksite and order discount, are to come later, and the User Guide says every contract will get a six-month trial period for them from the date they are implemented.
