3. How to register
To register as a contractor, you need to follow the process for setting up as a new employer.
When done, you’ll get a letter from HM Revenue and Customs (HMRC) with the information you need to start working as a Construction Industry Scheme (CIS) contractor.
If your business is based outside the UK but you do construction work here, you follow a different registration process.

You can also sign up for webinars and emails or watch videos from HMRC about CIS.
