What's the NAICS and SIC code for a holding company?
For a holding company, use NAICS 551112 (Offices of Other Holding Companies) in the US and SIC 64209 (Activities of other holding companies n.e.c.) in the UK.
United States, NAICS 2022
551112 Offices of Other Holding Companies
Offices of Other Holding Companies: companies that hold the shares of other companies without managing them.
SBA small business limit: $45.5 million average annual receipts.
United Kingdom, SIC 2007
64209 Activities of other holding companies n.e.c.
Activities of other holding companies n.e.c. Companies House also has sector-specific holding codes, 64201 to 64205.
Use this code when you register with Companies House or file your confirmation statement.
When a different code fits better
These are the codes most often confused with the main answer. Pick by the activity that earns most of your revenue.
| Code | Title | Use it if |
|---|---|---|
| NAICS 551114 | Corporate, Subsidiary, and Regional Managing Offices | the company actively manages its subsidiaries as a head office |
| SIC 70100 | Activities of head offices | the company is a head office that runs its subsidiaries day to day |
| SIC 64205 | Activities of financial services holding companies | it holds companies in the financial services sector |
Good to know
A holding company that only owns shares is not the same as a head office that manages a group. Pick the head office code if staff there make operating decisions for the subsidiaries.
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.
Codes checked against the US Census 2022 NAICS index and the ONS UK SIC 2007 index. Information only; confirm with the agency you file with.
