What This Code Means

Another extremely common catch-all code. It is popular with freelancers and service businesses that provide general business support. Virtual assistants, admin service providers and anyone offering mixed business services often use this code. If your primary service is more specific (marketing, IT, accounting), use the relevant specific code instead. This code has very wide HMRC benchmarks because it covers such a diverse range of businesses.

Businesses That Use This Code

  • Virtual assistant businesses
  • Business process outsourcing
  • Debt collection agencies
  • Credit rating companies
  • Freelance administrative support providers
