When a new company is incorporated, both Companies House and HMRC will issue reference numbers. This may take between 14 and 28 days. In order to submit documents electronically, we need to ask you to let us know the reference in each case.
HM Revenue & Customs call it a Unique Taxpayer Reference or a UTR. Companies House talks about an authentication code. Examples of the tax office form and the Companies House letter are shown below. In each case, please let us know the reference or the code. We don’t need the letter, just a simple email with the reference or the code, thanks.
Once we have the reference number from HMRC we will complete the form CT41G for you using our own electronic proforma. You do not need to do anything with the original paper form. File it in your system just in case you need the UTR later.
We will check that the Companies House authentication code works on their web site, and then we’ll keep it safe pending the submission of various forms in future.
