What are the deadlines for filing a GAO bid protest after a debriefing is held?

The deadline for filing a GAO protest after a debriefing is held is not later than 10 days after the date on which the debriefing is held (4 CFR 21.2(a)(2)). This applies to federal contract awards. If the agency delays the debriefing, the protest still must be filed within 10 days of the actual debriefing. The date the debriefing is offered by the agency is a factor for the automatic stay, but not for the protest deadline itself.

For an agency-level protest, the deadline is also no later than 10 days after the basis of protest is known or should have been known (FAR 33.103(e)). If an agency-level protest was filed first, any later protest to GAO must be filed within 10 days of actual or constructive knowledge of initial adverse agency action (4 CFR 21.2(a)(3); FAR 33.103(d)(4)). State and local government contracts follow their own procurement codes and specific portal guidelines, which may have different protest timelines.
