When a Small Business Award Is at Risk — Understanding SBA Size Protests
Are you planning on filing an SBA bid protest because of alleged affiliation with the awardee and another company? Or, are you the successful bidder and your competition alleges that you have violated the Ostensible Subcontractor Rule under 13 CFR 121.103? Our Washington, DC SBA bid protest lawyers are help to help clients navigate through the complex SBA regulations, and protect what rights they have in the United States federal procurement process.
Knowing what to do next in either situation can be very tricky. Many protests are dismissed because they do not meet the technical requirements. On the other hand, intervenors may attempt to respond to the size protest but may not fully understand the rules.
For many small federal contractors, winning a government contract can mark a turning point — years of bidding, certifications, and careful growth finally lead to something solid. But for some, that moment is short-lived. A size protest can interrupt everything. You could lose a multimillion-dollar government contract.
A competitor may challenge your small-business eligibility. Or you’ve just lost an award and suspect the winner shouldn’t have been eligible at all. You’re handed a process you didn’t design, with deadlines you didn’t set, and consequences you may not have anticipated. It’s not always about who did something wrong. Often, it’s about who understands how SBA actually works — and who doesn’t.
13 CFR 121.1001 Who may initiate a size status protest or request a formal size determination?
You can file a small business size status protest if you meet any of the following:
(i) Any offeror that the contracting officer has not eliminated from consideration for any procurement-related reason, such as non-responsiveness, technical unacceptability or outside of the competitive range;
(ii) The contracting officer;
(iii) The SBA Government Contracting Area Director having responsibility for the area in which the headquarters of the protested offeror is located, regardless of the location of a parent company or affiliates, the Director, Office of Government Contracting, or the Associate General Counsel for Procurement Law; and
(iv) Other interested parties. Other interested parties include large businesses where only one concern submitted an offer for the specific procurement in question. A concern found to be other than small in connection with the procurement is not an interested party unless there is only one remaining offeror after the concern is found to be other than small.

Information Required in an SBA Bid Protest
Two Places Small Business Contractors Usually Stand
1. You won a contract — and someone filed a size protest against you.
You now have days to respond. Not weeks. The SBA will ask for:
-
Tax returns
-
Payroll and W-2 information
-
Ownership and control documents
-
Revenue across potentially affiliated entities
If you’ve grown fast, or if your structure has changed, what used to be safe may no longer be.
You don’t get a second chance to submit your response. The size determination becomes binding.
2. You lost a contract — and believe the awardee shouldn’t qualify as small.
This is common in competitive industries. You’ve done the homework, you’ve checked SAM.gov, and you know — or strongly suspect — that the winning business exceeds the SBA size threshold or is backed by a larger firm.
The problem: most size protests fail because of timing, framing, or insufficient evidence — not because the underlying claim was wrong.
When Filing an SBA Size Protest, Mistakes Are Easy to Make — Even With Good Intentions
Many size challenges don’t come from bad actors. They come from misunderstanding affiliation, using outdated size thresholds, or assuming past eligibility applies to a new contract. Some examples:
-
A joint venture agreement that doesn’t meet SBA’s formal structure rules
-
Family-owned entities with overlapping management are being treated as one business
-
Rapid growth across related entities that tips the average receipts over the limit
-
Misapplying the wrong NAICS code and certifying small when you’re not
Once flagged, those missteps can become part of a government protest — or worse, a False Claims Act investigation.
What the SBA Actually Looks At
When a protest is filed (or when you’re defending against one), the SBA doesn’t just ask “Are you small?”
It asks:
-
What’s your revenue over the last five years?
-
Who owns and controls the company — directly and indirectly?
-
Do you share resources, office space, personnel, or management with another firm?
-
Do you participate in any mentor-protégé agreements or joint ventures?
-
Are you subcontracting more than allowed under the limitations on subcontracting rule?
And they measure all of this against the NAICS small business size standard assigned to that particular contract — not just your average standing.
What Happens After the SBA Receives a Small Business Bid Protest Under 13 CFR 121.1008?
SBA will provide a copy of the protest to the protested concern together with SBA Form 355, Application for Small Business Size Determination, by certified mail, return receipt requested, or by any overnight delivery service that provides proof of receipt.Once the SBA receives a small business bid protest, it will review the request and notify both parties of its decision. If the protest is resolved in your favor, the contracting officer must re-evaluate offers and make a new award to your company. The timeline for processing small business-size protests varies based on a variety of factors.
The SBA area office will make a small business size determination in approximately 15 business days of receiving the protest.If the SBA determines that the protested business is small, or dismisses the protest, you may award the contract.
If the SBA determines that the winning business is not small, the business is not eligible for that contract. The ineligible business can’t become eligible for the contract by reducing its size after the SBA’s determination.

For Those Under Small Business Fraud Scrutiny — The Concern Grows Quickly
Some small-business size protests reveal more than an eligibility issue. The SBA might refer your matter to an Inspector General or U.S. Attorney’s Office if they believe:
-
A size certification was knowingly false
-
You used a front company or pass-through to win an award
-
You concealed relationships that should have been disclosed
-
The same team is controlling “separate” companies bidding in the same industry
Even if there’s no intent to defraud, the False Claims Act doesn’t require criminal standards to apply. Violations tied to the NAICS size standard can trigger years of civil exposure or criminal liability — and damage reputations that took decades to build. Our SBA small business government contract fraud attorneys frequently address these types of cases.
Avoiding Dismissal of SBA Bid Protests
- avoid speculative allegations
- making sure that you have legal standing to file the protest and can show some level of prejudice
- making sure that you were not deemed ineligible for award for reasons other than size
- providing merit and evidence to support the allegations in the bid protest
