Most EU countries use Tax Identification Numbers (TINs) to identify taxpayers and facilitate the administration of their national tax affairs.

In the UK, this is known as your UTR (Unique Taxpayer Reference).

Within two to three weeks of registering a new limited company with Companies House, HMRC will have sent a letter to your registered office address. This letter is a CT41(G) Form which will contain your company’s 10-digit UTR.
