A GAO bid protest is a formal challenge to a federal contract award filed with the Government Accountability Office, resolved within 100 days under CICA.

Quick answer

A GAO bid protest is a formal challenge to a federal contract award filed with the Government Accountability Office, resolved within 100 days under CICA.


A GAO bid protest is a formal challenge to a federal procurement decision filed with the Government Accountability Office, the most widely used protest forum in the United States. The GAO issues a written decision within 100 calendar days, and filing automatically stays contract performance while the protest is pending.

What is a GAO Bid Protest?

The GAO adjudicates bid protests under the Competition in Contracting Act (CICA) and its own Bid Protest Regulations at 4 C.F.R. Part 21. Any interested party, an actual or prospective offeror with a direct economic interest in the procurement, may file a protest challenging the terms of a solicitation or an award decision.

Protests must generally be filed within 10 calendar days of when the protester knew or should have known the basis for its claim. For protests based on a debriefing, the 10-day clock runs from the date the debriefing was held or made available. The GAO dockets the protest, notifies the agency, and requests an administrative record. The agency has 30 days to submit its report, the protester responds, and the GAO issues a decision.

GAO protest decisions are fully public and searchable at gao.gov, making them one of the best free sources of insight into how agencies apply evaluation criteria. Decisions often quote verbatim from Source Selection Evaluation Board findings, revealing exactly what evaluators reward and penalize. The GAO sustains approximately 14-17% of protests decided on the merits annually, with another 30-40% resolved through voluntary corrective action before a decision is issued.

Why GAO Bid Protests matter for government contractors

The GAO protest forum is faster, cheaper, and more widely used than litigation at the Court of Federal Claims. A sustained protest can halt an award and force reevaluation, resolicitation, or a revised source selection. Even unsuccessful protests produce public decisions that improve competitive intelligence. Reviewing GAO decisions on similar contracts before submitting a proposal is a proven capture strategy. See also our guide to bid protests for a step-by-step overview.

Example

An IT firm loses a DHS cloud services award to a larger competitor. After the debriefing reveals the agency awarded the competitor a "Significant Strength" for a cloud migration approach the firm also proposed, the firm files a GAO protest arguing the evaluation was unequal. The GAO requests the agency's record, reviews the Source Selection Decision Document, and sustains the protest, finding the agency applied the evaluation criteria inconsistently.

Frequently Asked Questions

What is the cost to file a GAO bid protest?


Filing a GAO protest requires no filing fee. The primary costs are attorney fees and internal staff time. The GAO may recommend that the government reimburse protest costs if the agency unduly delayed taking corrective action.

Can the agency just keep working on the contract while a GAO protest is pending?


No, filing a timely GAO protest triggers an automatic CICA stay that prohibits the agency from authorizing performance on the contested contract. The agency head can override the stay by certifying urgent and compelling circumstances, but this is relatively rare.

How do I find GAO protest decisions on contracts similar to mine?


GAO publishes all protest decisions at gao.gov/legal/bid-protests. You can search by agency, date, or contractor name. Decisions often name the RFP, the evaluation criteria, and the specific weaknesses assigned, making them highly useful for proposal strategy.

What is the difference between a GAO protest and an agency-level protest?


A GAO protest goes to the independent Government Accountability Office and triggers a mandatory stay. An agency-level protest is filed directly with the contracting officer, carries no automatic stay, and is decided by the same agency whose decision is being challenged.
