The word “small” carries a specific meaning in federal contracting. It is not a feeling or a headcount you pick for yourself. It is defined by the U.S. Small Business Administration through size standards, and it determines whether you can compete for work reserved for small businesses.
Size depends on the NAICS code
The SBA sets a size standard for each six-digit NAICS code. Most standards are based on either average annual receipts or average number of employees. Industries where firms tend to be larger, such as certain manufacturing sectors, may have higher thresholds than industries where small firms are typical.
Because standards vary by code, a business can be small under one NAICS code and other than small under another. What matters for a given solicitation is the code the contracting officer assigned to it. You can find the current table of size standards on sba.gov.
How receipts and employees are measured
For receipts-based standards, the SBA generally looks at average annual receipts over a set number of completed fiscal years. For employee-based standards, it looks at average employment over a defined period, counting full-time, part-time and temporary employees. The specific calculation periods and definitions are set out in SBA regulations, which have been updated over time, so check the current rules rather than relying on older guidance.
Affiliation: the rule many firms overlook
When the SBA measures size, it includes not just your business but also affiliates. Affiliation can arise from common ownership, common management, control by another company, and certain other relationships. If two businesses are affiliated, their receipts or employees may be combined for size purposes.
Affiliation rules are detailed, and they have exceptions, such as for some approved joint ventures and mentor-protégé relationships. If your company has investors, sister companies or close business ties, talk to a government contracts professional before you certify your size.
When size is determined
In general, size is determined as of the date you submit your initial offer that includes price. You certify your size in your SAM.gov representations, and in some cases on individual offers. On long contracts, rules may require recertification in certain situations, such as after a merger or acquisition, or at specified points during the contract.
Why it matters for set-asides
Many federal contracts are set aside for small businesses or for specific types of small businesses. To compete, you must be small under the size standard for that solicitation. Congress has set a government-wide goal that a share of federal prime contract dollars go to small businesses, and agencies use set-asides as one way to meet those goals.
Success can eventually push a firm over the size standard for its main codes. Planning for that transition matters. Some firms broaden their capabilities, pursue full and open competitions, or build strong relationships as subcontractors before they outgrow small business status.
- Do you know the size standard for each NAICS code you list?
- Have you considered any possible affiliates?
- Do your SAM representations match your current situation?
Size rules can feel technical, but understanding them protects you from inaccurate certifications and helps you plan where to compete.
