Good to know
Payroll-only services have their own US code (541214).
You can list more than one code. Companies House accepts up to four SIC codes, and SAM.gov lets you add several NAICS codes, with one marked as primary.
What the code affects
- SBA programs and federal contracts: your NAICS code sets the size limit you must stay under to count as small. Check your size.
- SAM.gov registration: contracting officers search by NAICS, so list every code you can deliver work under.
- Companies House: your SIC code appears on the public register and in your confirmation statement.
