FAR 14.407-3 Bid Mistakes: Myths and Realities Before Award

By QuickBidSetup Editorial Team · Published October 30, 2026 · Sources linked below

When bids are unsealed on a sealed-bid federal procurement, discovering a pricing omission or calculation blunder creates immediate pressure. While administrative determinations exist to resolve errors prior to contract award, strict procedural limits govern what can be changed or pulled back. Estimators who understand the framework in FAR 14.407-3 Other mistakes disclosed before award can separate procurement realities from persistent industry misconceptions when assembling numbers on their bid day checklist.

Myth 1: Bid Corrections Can Be Used to Make a Nonresponsive Offer Responsive

Fact: The authority to correct mistakes applies solely to bids that are already responsive as submitted.

Under the opening text of FAR 14.407-3, administrative determinations are designed to minimize award delays when mistakes are alleged after bid opening but before award. However, contracting agencies cannot use this authority to allow a bidder to fix omissions or compliance failures that made the original bid nonresponsive. If the paperwork originally failed to meet the responsiveness requirements of the invitation for bids, the bid cannot be reworked into compliance under the pre-award correction rules.

Myth 2: A Low Bidder Can Always Elect to Withdraw Rather Than Perform

Fact: The government can compel bid correction instead of permitting withdrawal under specific pricing conditions.

Bidders frequently assume that alleging an error automatically unlocks an exit ramp. Under FAR 14.407-3(b), if a bidder asks to withdraw rather than correct, the agency head may determine to correct the bid and refuse withdrawal if two conditions exist alongside clear and convincing evidence:

• The clear and convincing evidence proves both the existence of the mistake and the bid actually intended.
• The bid remains the lowest received both in its uncorrected form and in its corrected form.

If the evidence fails to justify correction or withdrawal under the regulatory standards, FAR 14.407-3(d) also permits the agency head to determine that the bid can be neither withdrawn nor corrected.

Myth 3: Proving an Intended Bid Faces the Same Evidentiary Bar as Proving an Error

Fact: Establishing an intended price requires clear and convincing evidence, while withdrawal may rest on a lower threshold of proof.

To modify an amount upward under FAR 14.407-3(a), the bidder must provide clear and convincing evidence of both the mistake itself and the specific bid actually intended. If the evidence establishes the error but fails to demonstrate the exact intended figure—or if the evidence reasonably supports a mistake without reaching the clear and convincing standard—FAR 14.407-3(c) allows an official above the contracting officer to permit withdrawal rather than correction. Reviewing our guide on how to handle bid mistakes in federal bidding illustrates why separating the existence of an error from the intended calculation is vital during dispute reviews.

Myth 4: Displacing a Lower Bidder Can Rely Entirely on Internal Worksheets

Fact: When a correction would displace a lower bid, the error and the intended price must be ascertainable substantially from the bid and invitation alone.

A contractor cannot simply bring forward private estimating software printouts or handwritten takeoff sheets to jump over another lower bidder. FAR 14.407-3(a) explicitly provides that if a proposed correction would displace one or more lower bids, the agency head cannot authorize the correction unless both the existence of the error and the bid actually intended can be ascertained substantially from the invitation and the bid submission itself. This safeguard prevents bidders from using post-opening documentation to adjust numbers competitively against other firms.

Myth 5: Contracting Officers Can Approve Corrections Based on Informal Statements

Fact: Agency determinations require formal documentation, verified evidence, and legal counsel concurrence.

A simple statement from administrative personnel expressing satisfaction that an error occurred is legally insufficient under FAR 14.407-3(g). When a contracting officer suspects an error—such as when a price is significantly below other offers or the government estimate—they must request verification. If the bidder alleges an error, the contractor must submit a formal written request to withdraw or modify, supported by statements (sworn if possible) and pertinent records:

1. The bidder's file copy of the submitted bid.
2. Original worksheets and preparatory calculation data.
3. Subcontractor quotes and supplier price lists.
4. Any additional data proving how the error occurred and what price was intended.

The contracting officer compiles this evidence with bid abstracts, specifications, bid expiration dates, and written recommendations to forward to the designated agency authority. Before issuance, every proposed determination under FAR 14.407-3 must receive the concurrence of agency legal counsel, and doubtful cases may be submitted to the Comptroller General for advance decision.
