Small business set-aside contracts represent a significant share of federal procurement. Because larger firms are excluded, set-asides provide a real competitive advantage for qualifying contractors. Unfortunately, they also carry serious risks for contractors who think they qualify but do not.

A single unfavorable size determination can disqualify a company from an award and trigger a protest. In cases involving knowing misrepresentation, it can create False Claims Act liability. The SBA's rules on size and affiliation are an active area of regulatory change, and the stakes are high.

How size is determined

Whether a company qualifies as a small business depends on the size standard assigned to the NAICS code for the specific procurement. For construction contracts, size standards are typically expressed as average annual receipts over the prior three to five fiscal years.

The relevant figure is not the contract value. It is the company's overall revenue, averaged across the applicable period. That calculation is straightforward when a company stands alone. It gets complicated when affiliation is involved.

Affiliation and why it matters

Affiliation can arise through common ownership, common management, contractual relationships that create economic dependence, or, critically for construction firms, the newly clarified rules around joint ventures and mentor-protégé relationships.

When affiliation exists, the SBA aggregates the revenues of affiliated businesses for size purposes. A company with modest revenues of its own can be ineligible for set-asides because of a larger affiliate's size. That result surprises a lot of contractors who have never thought of themselves as affiliated with anyone.

The affiliation analysis is fact-specific and not always intuitive. A new relationship or transaction can change the picture for a company that has operated for years without triggering affiliation concerns.

Joint ventures and the present effects rule

Joint ventures are common in construction procurement, particularly on large or complex federal projects where teaming allows firms to combine capabilities. The SBA has specific rules governing when a joint venture qualifies as small, and recent regulatory activity has focused on preventing large businesses from accessing set-aside contracts through nominally small partners.

The composition, management structure, and work-share arrangements of the joint venture all matter for size purposes. Getting this wrong, even unintentionally, can expose both partners to size protests and potential misrepresentation liability.

Mentor-protégé arrangements

The SBA's mentor-protégé program allows large businesses to assist small businesses through formal mentoring relationships. Joint ventures formed under approved mentor-protégé agreements receive a specific exception from the normal affiliation rules. That exception is valuable. It allows small businesses to access the resources and past performance of their mentors without triggering affiliation.

The exception comes with eligibility and compliance requirements that must be maintained throughout the relationship. Letting those lapse can eliminate the protection.

What contractors should be doing now

Any contractor that relies on small business status for a meaningful portion of its federal revenue should conduct a current affiliation analysis. Not the analysis done at certification. Not the one from the last recertification event. A current one.

  1. Review all ownership, management, and contractual relationships for potential affiliation triggers.
  2. Confirm that revenue calculations reflect the current applicable size standard and lookback period.
  3. Audit any joint venture or teaming arrangements for compliance with SBA joint venture requirements.
  4. Ensure that any mentor-protégé arrangement remains in compliance with program terms.
  5. Confirm that SAM.gov registration and representations reflect current accurate information.

Business relationships change. Ownership changes. Revenue levels change. The affiliation picture needs to keep up.
