Small business owners in GovCon, this is important to understand before your next teaming arrangement.
The ostensible subcontractor rule (13 C.F.R. § 121.103(h)(3)) exists to prevent a common workaround: a small business winning a set-aside contract on paper while a larger subcontractor performs the actual work. SBA and its Office of Hearings and Appeals have one name for that arrangement, an ostensible subcontractor, and finding one means the prime and the sub are treated as affiliated for size purposes.
What that means in practice: if their combined size exceeds the applicable size standard, the small business is ineligible. Contracts can be terminated post-award. Status certifications SDVOSB, WOSB, and 8(a) can be challenged and lost, not just size.
SBA's OHA issued two significant decisions in 2025 that every small business should know about. In Bowhead Enterprise (May 2025), the prime demonstrated that it was meeting the subcontracting limitations, and OHA ruled that compliance with those limits is a bright-line defense against ostensible subcontractor allegations. In Veteran Elevated Solutions (also 2025), the prime could not make that showing, lost the primary and vital requirements analysis, and was found affiliated with its large business sub.
The difference between those two outcomes is documented in the compliant performance structure in the proposal and the teaming agreement.
If your teaming arrangement puts a large business in the driver's seat, you are not a prime contractor. You are a pass-through. And the government has no interest in paying for that.
Comment COMPLIANCE if you want resources on structuring defensible teaming arrangements.
