UTR number is of great importance in various tax-related transactions, such as filing tax returns, registering self-employment, requesting tax refunds, or contacting tax departments. Learning about this tax reference is an important part of performing tax obligations. In this passage, we are going to explore what is a UTR number, who needs to apply for one, how to get it, and some frequently asked questions.

What is a UTR Number

UTR number, referring to a Unique Taxpayer Reference, is a tax identification number in the UK. The number is issued by Her Majesty’s Revenue and Customs (HMRC) at the time of registering for a self-assessment tax return or establishing a limited company. It is used to identify a taxpayer’s account and link payments to the bills. It remains unchanged after issuing throughout your whole life. 

The code consists of 10 digits and some end with the letter “K”. Let’s see its format.

  • First 2 digits – representing the issuing authority, a specific HM Revenue and Customs (HMRC) office.
  • Next 6 digits – representing the owner of the UTR and distinguish different taxpayers in the same tax office.
  • Final 2 digits – validating and ensuring the accuracy of the code by detecting errors and discrepancies.

Who Needs a UTR Number

The NTR number is needed when HMRC tracks your tax obligations and refunds overpaid tax, when you file self-assessment tax returns or calculate company tax, and when you partner with accountants.
