Frequently Asked Questions: SBA Size Standards in Federal Procurement
Essential guidance for federal contractors, capture managers, and small business liaison officers (SBLOs) navigating Small Business Administration size determinations.
How is the SBA 5-year average annual receipts calculated?
Under the Small Business Runway Extension Act and 13 CFR § 121.104, annual receipts are calculated by averaging the gross revenues (receipts) of your business plus all domestic and foreign affiliates over the 5 most recently completed federal tax years. If your business has been operational for less than 5 years, divide total receipts by the number of weeks in business and multiply by 52.
What is the SBA affiliation rule (13 CFR § 121.103)?
When determining your small business size, the SBA aggregates the receipts or employee counts of all affiliated businesses. Affiliation exists when one business controls or has the power to control another (through majority stock ownership, voting agreements, common management, identity of interest, or economic dependence), or when a third party controls both. Failure to aggregate affiliates is the leading cause of size protests in federal procurement.
What is the difference between revenue-based and employee-based size standards?
Most service, consulting, and construction industries are evaluated using 5-year average annual receipts (dollars). Most manufacturing, research, and supply industries are evaluated using employee headcount, calculated as the average number of employees for each pay period over the preceding 24 calendar months (including part-time and temporary staff).
Does meeting the SBA size standard automatically qualify my firm for 8(a), WOSB, SDVOSB, or HUBZone?
No. Meeting the SBA size standard is only the baseline requirement that proves your business is "small." Socio-economic federal programs require independent eligibility criteria: 8(a) requires proving social and economic disadvantage; WOSB requires at least 51% unconditional ownership and operational control by women; SDVOSB requires service-disabled veteran ownership; and HUBZone requires a principal office in a designated HUBZone with at least 35% of employees residing in a HUBZone.
What happens when a federal contractor exceeds the SBA size ceiling?
When your rolling 5-year average receipts or 24-month headcount exceeds the applicable NAICS threshold, your company "graduates" and is classified as Other Than Small (Large Business). You can no longer bid on prime small business set-asides under that NAICS code. However, you can compete for full-and-open contracts, participate as a mentor in the SBA Mentor-Protégé Program (13 CFR § 125.9), or serve as a large subcontractor with mandatory Small Business Subcontracting Plans (FAR Subpart 19.7).
