Small Business

Definition

A Small Business, for federal contracting purposes, is a business that meets SBA's size standards for the applicable NAICS code. Size is measured by average annual receipts (typically over the most recent 3 or 5 completed fiscal years) or employee count, depending on the NAICS. Firms self-certify as small when they register in SAM.gov under specific NAICS codes. SBA's size standards table is the authoritative source. Affiliation rules under 13 CFR 121.103 can aggregate size across affiliated entities, so JV and investment structures can trigger size issues.

Why It Matters

Small-business status is the most fundamental socioeconomic classification in federal contracting. Federal agencies have 23% governmentwide small-business goals, with set-asides and sole-source tools to meet them. Losing small-business status (through revenue growth, affiliation, or acquisition) is often a major strategic transition, and many firms plan for it years in advance, moving into graduation-period vehicles like OASIS Unrestricted or MAS that can serve both small and mid-tier competition.

Example

A services firm with $36M in average annual revenue remains small under NAICS 541512 ($34M standard) because its 3-year average is $33.5M. It uses this window to win two final 8(a) sole-source awards before graduating to the full-and-open market.
