GAO Bid Protest Procedures: Deadlines, CICA Stay & Remedies

A GAO bid protest is a formal challenge filed with the Government Accountability Office when a bidder believes a federal agency violated procurement law during a contract competition. To follow GAO bid protest procedures, you file electronically through the GAO’s Electronic Protest Docketing System (EPDS), pay a $500 filing fee, and meet strict deadlines that vary by protest type. The GAO then issues a decision within 100 days.¹ In fiscal year 2025, the GAO reported an overall effectiveness rate of 52 percent, meaning more than half of protests resulted in either a sustained decision or voluntary corrective action by the agency.²

Who Can File

The GAO limits protests to “interested parties,” meaning actual or prospective bidders whose direct economic interest would be affected by the contract award or the failure to award it.³ You need to show that overturning the agency’s decision would put you in a realistic position to receive the contract. Subcontractors, taxpayers, and companies that never submitted a proposal lack standing.

One boundary worth flagging: if your real argument is that a competitor doesn’t actually qualify as a small business under the contract’s industry size standard, that belongs at the Small Business Administration’s Office of Hearings and Appeals, not the GAO. The Small Business Act gives the SBA exclusive authority over size and status determinations, and the GAO will dismiss protests that are really size challenges.

There are also jurisdictional limits by contract type. Task orders under Department of Defense contracts must be worth at least $25 million for GAO to take the case, and task orders under civilian agency contracts must be worth at least $10 million. Federal Supply Schedule orders can be protested regardless of value.

Grounds for a Protest

Protests fall into two broad categories. Solicitation challenges argue that the requirements themselves are unduly restrictive, ambiguous, or otherwise unlawful. Evaluation and award challenges argue that the agency applied its stated criteria improperly, ignored weaknesses in the winner’s proposal, or made an unreasonable technical or price judgment.⁴ The most common grounds for sustained protests in fiscal year 2025 were unreasonable technical evaluations, flawed cost or price evaluations, and improper rejection of proposals.²

Filing Deadlines

Miss a deadline by one day and the GAO dismisses the protest without reaching the merits. The timelines are unforgiving and depend on what you’re challenging.

Solicitation Challenges

If your protest targets a flaw in the solicitation, you must file before the deadline for submitting initial proposals. Once you submit a proposal under terms you consider flawed, the issue is waived.⁵

Evaluation and Award Challenges

For all other protests, you have 10 days from when you knew or should have known the basis for your protest.⁵ When a required debriefing is involved, the Federal Acquisition Regulation delays the protest clock until the debriefing concludes.⁶

DoD Enhanced Debriefings

Department of Defense procurements add a step. After receiving a written or oral debriefing, you can submit follow-up questions within two business days, and the agency then has five business days to respond in writing. The debriefing isn’t considered concluded until that written response is delivered, and the protest window doesn’t start until then.⁷ For DoD contracts, you then have five days after the debriefing concludes to file a protest that triggers the automatic stay.⁸

Supplemental Protests

If new grounds surface after your initial filing, often through the agency report, the same 10-day rule applies from the date you learn of the new issue.⁵

What Your Filing Must Contain

A protest that just says “the agency got it wrong” goes nowhere. Your filing must include:

Your name, street address, email, and phone number.
The solicitation or contract number and the contracting agency.
A detailed explanation of how the agency violated procurement law or the solicitation’s own terms. This is the core of the protest and needs enough specificity for the GAO to assess whether you have a viable claim.
Supporting evidence: excerpts from the solicitation, evaluation documents, correspondence with the contracting officer, and anything else that backs your arguments.
The relief you want, such as re-evaluation, a new award decision, or cancellation of the solicitation.

Every protest is filed through EPDS and must be signed by the protester or their representative.⁹ The filing fee is $500, in effect since October 2024, and it’s not refundable regardless of outcome.¹

Within one day after filing, you must serve a complete copy of the protest and all attachments on the contracting officer or the person designated in the solicitation.¹⁰ Failing to provide that timely notice is a common reason for dismissal. If you’re scrambling to meet the filing deadline late at night, remember you still owe the agency a copy the next day.

The CICA Automatic Stay

One of the main reasons companies protest at the GAO rather than elsewhere is the automatic stay of contract performance under the Competition in Contracting Act. When the agency receives notice of a timely protest within 10 days after award, or within 5 days after a required debriefing (whichever is later), the contracting officer must immediately stop the contractor from performing.⁸ The freeze lasts while the protest is pending.

The stay isn’t absolute. The head of the procuring activity can override it with a written finding that either performance is in the best interests of the United States or urgent and compelling circumstances won’t permit waiting for a GAO decision.⁸ Overrides are rare because they invite scrutiny, and a protester can challenge the override at the U.S. Court of Federal Claims.

What Happens After You File

Once the GAO accepts the protest, the process runs on a tight schedule.

Agency Report

The contracting agency has 30 days to submit a report to the GAO with the documents and legal reasoning behind its decisions.¹¹ The report typically includes the solicitation, evaluation records, the source selection decision, and the agency’s legal response to each protest ground. Under the express option, the agency report is due within 20 days.

Your Comments

After receiving the agency report, you have 10 days to file written comments responding to the agency’s evidence and arguments. Under the express option, that shrinks to 5 days.¹¹ Many protests are won or lost here. If you fail to file comments, the GAO will dismiss the protest.¹²

Intervenors

The contract winner gets a seat at the table. Once the agency receives the protest, it notifies the awardee, who can intervene to defend the award, access the agency report subject to any protective order, file comments, and even move to dismiss.¹⁰ If no contract has been awarded yet, any bidder with a realistic chance of winning can intervene.

Decision

The GAO must issue its decision within 100 days from filing under the standard track. Cases suitable for faster resolution can go on an express track with a 65-day deadline.¹³ The GAO also offers alternative dispute resolution.

Protective Orders and Sensitive Information

Federal procurements involve proprietary pricing, trade secrets, and source-selection-sensitive material that competitors should never see. The GAO handles this through protective orders that restrict who can access protected documents during the protest.

The GAO can issue a protective order at a party’s request or on its own. Access is generally limited to outside counsel and their consultants who are not involved in competitive decision-making for any company that could benefit from the information.¹⁴ Requesting a protective order is your counsel’s responsibility. If you don’t ask, you risk being shut out of key documents in the agency report.

If your protest itself contains proprietary information, you must file a redacted version within one day after filing the unredacted protest.¹⁰ Violating a protective order carries serious consequences, including referral to bar associations, restrictions on practicing before the GAO, or dismissal.¹⁴

How Protests End

A protest can end in five ways: you withdraw it, the GAO dismisses it on procedural grounds, the GAO denies it on the merits, the GAO sustains it, or the agency takes voluntary corrective action.

Corrective Action

Often the agency reviews the protest and decides to fix the problem itself rather than litigate. Corrective action can take the form of re-evaluating proposals, amending the solicitation, or making a new award decision. When the agency’s fix resolves the issues raised, the GAO dismisses the protest as academic.¹⁵ This is where most of the 52 percent effectiveness rate comes from: only 14 percent of merit decisions resulted in a formal sustain in fiscal year 2025, but a much larger share of cases ended favorably through voluntary corrective action.²

Sustained Protests and Remedies

When the GAO sustains, the Comptroller General may recommend that the agency recompete the contract, issue a new solicitation, terminate the awarded contract, award the contract in compliance with law, or any combination.¹³ GAO recommendations are not technically binding, but agencies follow them in the vast majority of cases. An agency that declines must report its reasons to the GAO within 60 days.

Getting Your Costs Back

If the GAO sustains the protest or finds that the procurement violated a statute or regulation, it can recommend that the agency reimburse your protest costs. Recoverable costs include reasonable attorney fees, consultant and expert witness fees, and bid and proposal preparation costs.¹¹

For companies that aren’t small businesses, attorney fees are capped at $150 per hour unless the agency finds that the cost of living or limited availability of qualified attorneys justifies more. That $150 figure also serves as a benchmark for evaluating whether small business attorney fees are reasonable.¹¹ You must file your cost claim with the contracting agency within 60 days after receiving the GAO’s recommendation. Miss that window and you forfeit the right to recover.

Reconsideration

Any party that participated in the protest can request reconsideration if they believe the GAO made an error. The request must be filed within 10 days after the basis for reconsideration becomes known or should have been known.¹⁰ The bar is high. You need an error of fact or law, not a rehash of arguments the GAO already considered.

Other Forums

The GAO isn’t the only option. Two other venues handle procurement disputes.

Agency-Level Protests

You can file directly with the contracting agency. Agency-level protests are the least formal and least expensive route, which makes them accessible for smaller firms that don’t want to hire outside counsel for a GAO filing. The downside: you’re asking the same organization that made the decision to reverse itself, and there is no automatic stay of contract performance.

Court of Federal Claims

The U.S. Court of Federal Claims provides a judicial forum for bid protests. Filing costs $405.¹⁶ There is no automatic CICA stay at the Court of Federal Claims, so you would need a temporary restraining order or preliminary injunction to halt performance while your case is pending. Court proceedings involve full litigation with discovery and potentially oral argument, which makes them more expensive and slower than the GAO’s 100-day process. Court decisions are binding, unlike GAO recommendations, and the court reviews agency actions to decide whether they were arbitrary, capricious, or contrary to law. Some protesters file simultaneously at the GAO and the Court of Federal Claims, though the GAO will dismiss its case if the court takes jurisdiction over the same issues.
