1. When Can a Federal Contractor File a Bid Protest?
At GAO, a protester generally must be an actual or prospective bidder or offeror whose direct economic interest would be affected by the award or failure to award the contract.
A federal bid protest may challenge a defect that exists before proposals are submitted or an evaluation and award decision learned about later. Those situations have different timing rules.
Pre-Award Challenges to Solicitation Terms
A prospective contractor may challenge an apparent solicitation problem involving matters such as restrictive specifications, ambiguous requirements, improper evaluation criteria, or terms inconsistent with procurement law.
An apparent defect generally must be protested before bid opening or the closing time for initial proposals.
If an amendment later introduces the disputed term, the protest generally must be filed before the next closing time. If no further submission is expected, the GAO rules can instead require filing within 10 days after the defect was known or should have been known.
Waiting until after award can therefore be too late for an objection that was apparent before proposals were due.
These solicitation and award issues are part of the broader Federal government contracts framework, but a bid protest has its own jurisdictional and filing rules.
Post-Award Challenges to an Evaluation or Award
After award, an unsuccessful offeror may identify a protest basis in the award notice, evaluation explanation, or debriefing.
Potential issues can include an evaluation that departs from the solicitation, materially unequal treatment, an unreasonable cost or price analysis, improper discussions, or a source-selection decision that lacks adequate support.
A contractor's belief that its proposal was better is not enough. The protest should identify a procurement error and explain how correcting that error could affect the protester's competitive position.
GAO's FY2025 reporting identified unreasonable technical evaluation, unreasonable cost or price evaluation, and unreasonable rejection of a proposal among the most prevalent grounds on which protests were sustained.
2. How Quickly Must a Bid Protest Be Filed?
GAO deadlines are measured in calendar days, and some protests must be filed before the ordinary 10-day rule would apply.
The contractor should separately calculate the deadline for GAO to consider the protest and the shorter timing that may be necessary to obtain a CICA suspension of award or performance.
GAO Deadlines, Debriefings, and EPDS Filing
For protest grounds not involving an apparent solicitation defect, a GAO protest generally must be filed no later than 10 days after the basis was known or should have been known.
There is a specific exception for certain procurements conducted on the basis of competitive proposals where a debriefing is requested and, when requested, is required.
For grounds covered by that required-debriefing exception, the initial GAO protest must not be filed before the offered debriefing date and is generally due within 10 calendar days after the debriefing is held.
That rule does not revive an untimely challenge to an apparent solicitation defect that should have been protested before the proposal deadline.
A contractor should immediately preserve:
The award notice;
The date the debriefing was requested;
The offered debriefing date;
The date the debriefing was held;
Written debriefing materials;
Follow-up questions and agency responses;
The date each potential protest basis became known.
A voluntary or non-required debriefing does not necessarily receive the same GAO timeliness treatment.
GAO filings generally must reach the Electronic Protest Docketing System, or EPDS, by 5:30 p.m. Eastern Time to count as filed that day. An apparent solicitation challenge must still satisfy any earlier bid or proposal closing time.
CICA Stay Timing Is a Separate Calculation
A protest can be timely for GAO consideration without qualifying for a statutory suspension of contract performance.
For a post-award protest, the CICA notice window generally ends on the later of:
10 days after the date of contract award; or
5 days after the debriefing date offered for a debriefing that was timely requested and, when requested, required.
The procuring agency must receive GAO's notice within that period for the statutory suspension requirement to apply, subject to applicable exceptions.
The award date should not be replaced with the date the disappointed bidder happened to read the award notice.
Department of Defense procurements can require an additional timing analysis. For covered DoD required post-award debriefings, an offeror may submit related written follow-up questions within two business days. When timely questions are submitted, the debriefing remains open until the agency provides its written responses, and the statutory five-day period is affected accordingly.
Even when a CICA stay is triggered, applicable law permits authorized continuation of performance in specified circumstances.
3. Agency Protests, GAO, and the Court of Federal Claims
The best protest forum depends on the procurement, timing, available record, desired relief, and business objective.
Agency-level review, GAO, and the U.S. Court of Federal Claims do not use identical procedures or mechanisms for delaying an award or contract performance.
Agency-Level Protests and GAO
An agency-level protest asks the procuring agency to reconsider its own procurement action.
Under the traditional codified FAR framework, apparent solicitation defects generally must be challenged before bid opening or the proposal deadline, while other agency protests generally have a 10-day filing rule.
In 2026, however, agency-level protest procedures should also be checked against the solicitation, agency supplements, and applicable FAR class deviations. Agencies implementing the Revolutionary FAR Overhaul may use reorganized Part 33 procedures rather than relying only on the codified FAR section numbering.
Filing first with the agency does not indefinitely suspend the GAO deadline.
When a timely agency protest precedes a GAO protest, the subsequent GAO filing generally must occur within 10 days after actual or constructive knowledge of initial adverse agency action, subject to the GAO timeliness rules.
GAO and the U.S. Court of Federal Claims
GAO operates under the bid protest procedures in 4 CFR Part 21.
The U.S. Court of Federal Claims has jurisdiction under 28 U.S.C. §1491(b) over specified procurement challenges brought by interested parties, including challenges to solicitations, proposed awards, contract awards, and certain statutory or regulatory violations connected with a procurement.
The court can provide declaratory and injunctive relief. Monetary relief under this bid-protest jurisdiction is limited to bid preparation and proposal costs.
Filing a case at the Court of Federal Claims does not itself trigger a CICA stay. A contractor seeking to stop award or performance may need a government agreement to withhold action or temporary or preliminary injunctive relief from the court.
A protest challenging contract selection is also different from a dispute that arises during performance of an existing contract, which can require a separate government contract dispute analysis.
4. How the Procurement Record Supports a Bid Protest
A strong protest connects the solicitation requirement, what the protester proposed, what the agency did, and how the alleged error could affect the selection decision.
The record is more useful when each document is tied to a specific evaluation issue rather than presented as a general list of materials.
Connecting the Solicitation, Proposal, and Debriefing
The solicitation and amendments establish the evaluation requirements the agency was supposed to apply.
The protester's proposal shows what it actually offered in response to those requirements. Debriefing information can then reveal why the agency assigned a weakness, deficiency, rating, or other evaluation result.
For example, review can compare:
A challenged weakness with the stated evaluation criterion;
The agency's explanation with the relevant proposal passage;
Treatment of the protester's proposal with lawfully available information about other proposals;
The source-selection rationale with the evaluation record and stated best-value methodology.
The protest should then explain why correcting the identified error could matter to the award decision.
This approach connects evidence to both the alleged procurement error and competitive prejudice.
Protective Orders, the Agency Report, and Comments
GAO may issue a protective order covering proprietary, confidential, or source-selection-sensitive material.
A company may file a GAO protest without an attorney. After a protective order is issued, eligible attorneys and consultants retained by counsel may apply for admission.
GAO considers whether an applicant participates in competitive decision-making and whether access creates a significant risk of inadvertent disclosure. Protected information cannot be shared with client personnel who have not received authorized access.
When a protest proceeds to an agency report, that report can include the contracting officer's statement, legal memorandum, relevant proposals, evaluation documents, solicitation materials, and other procurement records.
Comments on the agency report are generally due within 10 days after the agency files the report, unless GAO establishes a different deadline or grants an extension. Failure to file timely comments results in dismissal of the protest.
Additional documents or protected material can also reveal supplemental protest grounds, which must be evaluated under their own timeliness rules.
5. Frequently Asked Questions
GAO generally must issue a decision within 100 calendar days after a protest is filed.
Some protests end earlier through dismissal, withdrawal, agency corrective action, or another procedural resolution.
Filing alone does not ensure a suspension of performance.
A GAO protest must satisfy the applicable CICA notice timing and other statutory requirements. Even when the suspension requirement applies, authorized exceptions can permit performance to continue.
A company may file a GAO protest without an attorney, but access to protected procurement information is separately restricted.
Eligible attorneys and consultants retained by counsel can apply for admission to a GAO protective order. Protected information generally cannot be disclosed to client personnel who lack authorized access.
A sustained GAO protest does not automatically give the contract to the protester.
GAO recommends corrective action appropriate to the procurement error. That may include reevaluation, a new source-selection decision, changes to the solicitation, reopening part of the competition, or another corrective step.
6. Federal Bid Protest Representation
A contractor may need an immediate assessment after an unfavorable award notice, an apparent solicitation defect, or a debriefing that raises questions about the agency's evaluation.
A bid protest attorney can compare the award notice, debriefing dates, solicitation requirements, and evaluation findings to identify potential protest grounds and the deadlines for filing and preserving a possible stay. Representation may also include protective-order applications and record review, agency-report comments, timely supplemental grounds, and evaluation of proposed corrective action.
