• Bid Protests

    Federal government procurement contracts may be protested by bidders or other interested parties. GAO's Procurement Law Division adjudicates those bid protests.

  • GAO's E-filing System for new bid protests filed on or after May 1, 2018

    GAO has established a secure and easy-to-use web-based electronic bid protest filing and dissemination system (EPDS) that will be mandatory for all new protests (excluding those that include classified material) filed on or after May 1, 2018. Prior to the full implementation of EPDS, please continue to submit your protest documentation as described here.

    Prior to rolling the system out for all new protests, GAO is conducting a limited pilot program of the system. GAO will designate several protests filed on or after February 1, 2018 for inclusion in the pilot program. If GAO selects your protest for the pilot, you will be notified and given detailed instructions. For cases included in the pilot program, users should review and follow the EPDS Instructions (except for the provisions regarding payment of the filing fee) available below, and make all subsequent filings related to the protest in EPDS.

    When the system is fully implemented all protesters will be required to use the system to file new protests, and there will be a $350 filing fee. Funds from the filing fee will be used to pay for the operation and maintenance of the system. The filing fee will not apply during the period of the pilot program.

    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 epdsfeedback@gao.gov.

    • File a Bid Protest

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

    • E-mail

      Protests and related documents filed by e-mail should be sent to protests@gao.gov. 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 also will 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 time manner, send your filing by another method or call the bid protest status line for assistance.
