What is the CIS online service?

The CIS online service is a HMRC online service which allows CIS contractors to file their monthly returns and verify subcontractors.

If you are a CIS contractor, you can set up an online account to simplify the tasks you have to complete as a contractor.

You will need the following information:

  • An email address
  • Your Employer Reference Number (ERN)
  • Your 13-digit Accounts Office reference number

You will also need a Government Gateway account to access the service.

If you have problems signing up for the service, you can call the HMRC technical helpline on 0300 200 3600. Lines are open between 8am and 8pm, Monday to Friday; 8am to 4pm on Saturday and 9am to 5pm on Sunday. The helpline is closed on Easter Sunday, Christmas Day, Boxing Day and New Year’s Day.

Sometimes the service can be slow during busy times – if this is the case when you are trying to access the system, HMRC recommend that you try again later. However, they don’t give any information about their busy and less-busy times so we’re afraid it is going to have to be a little trial and error if you wish to find a less-busy time.
