Requires certification of small business status for participation in small business set-asides.
Applicability: Required when the procurement is set aside for small business, HUBZone, women-owned, or service-disabled veteran-owned concerns.
Key Requirements
Accurately self-certify small business status based on size standards for your NAICS code
Understand affiliation rules—are you truly independent?
Disclose if you're planning to use subcontractors in key areas
Maintain documentation supporting your size certification for 3+ years
Notify the government of any change in status during performance
Common Issues & Pitfalls
Misunderstanding size standards for your industry—using wrong threshold
Over-affiliating with other companies and losing small business status
Using the same SBA size standard across multiple NAICS codes when they differ
Not recognizing that joint ventures affect size status
Failing to plan subcontracting strategy before responding to small business set-asides
Contractor Guidance for Your Bid
Size status is federal gold. If you qualify as small for your NAICS code, SAM.gov will mark you as small and agencies can restrict competition to you. But misrepresenting size or losing status during performance triggers debarment risk. Understand your exact size standard, document it, and never misrepresent status. If borderline, get an SBA size determination before bidding.
