Before you rely on this
- Affiliates count. SBA adds the receipts or employees of your affiliates (companies that control you, that you control, or that share common ownership or management) to yours. See 13 CFR 121.103.
- Receipts are a 5-year average. Average annual receipts are generally your total receipts over your last 5 completed fiscal years divided by 5 (13 CFR 121.104).
- Employees are a 24-month average. Employee-based standards use your average number of employees per pay period over the preceding 24 completed calendar months, counting part-time and temporary staff (13 CFR 121.106).
- The contract decides the code. For a federal contract, the contracting officer assigns one NAICS code in the solicitation, and that code’s size standard is the one that counts.
- Check officially. Use the official SBA Size Standards Tool and keep your SAM.gov registration current.
