File a Bid Protest

GAO's E-filing System

GAO has established a secure and easy-to-use web-based electronic bid protest filing and dissemination system (EPDS) that is mandatory for all new protests (excluding those that include classified material) filed on or after May 1, 2018.

Protesters are required to use the system to file new protests, and there is a $350 filing fee. Funds from the filing fee will be used to pay for the operation and maintenance of the system.

Explore the technical reference materials below to understand more about using our new system.

If you have any questions or comments about EPDS or its related reference materials, please contact

Submissions Not in the E-Filing Program


This section provides information for submissions of supporting documentation in connection with protests filed before May 1, 2018 and are not filed using EPDS.

A document is considered "filed" when it is received by GAO by 5:30pm, ET. Bid Protest Regulations, 4 C.F.R. 21.0(f). Filings may be sent by e-mail, fax, the Postal Service or commercial carrier, or delivered by hand.


Documents filed by e-mail should be sent to Once your filing has been received at GAO, you will receive an automated reply advising that a file number and attorney will be assigned to the filing. The reply will also advise that the filing information and status of the filing are available on our online Bid Protest Docket, accessible via the Legal Products link on GAO's home page, or by calling our protest status line at 202-512-5436. If you do not receive an automated reply, GAO did not receive your e-mail filing. To ensure your filing is received in a timely manner, send your filing by another method or call the bid protest status line for assistance.


Fax all filings to 202-512-9749.
