What is a UTR number?

UTR stands for Unique Taxpayer Reference.  

It is a 10 digit number that HMRC issued to you when you registered successfully for self employment.

This reference number is unique to you and means that HMRC can identify you, just like your passport number or national insurance number. For this reason it is really important you hold onto it.

Every time you speak to HMRC on a self employment issue they will ask you to provide your personal details, including this 10 digit number.

Where To Find Your UTR number?

Your unique reference number will be shown on any correspondence you receive from HMRC.  Here are some of typical documents where you will be able to find it:

  • Your HMRC Tax Return;
  • HMRC Statement of Account;
  • HMRC Payment Reminders or Late Payment Letters;
  • Your SA250 which is a letter issued when you first registering for self assessment notifying of successful registration;
  • Online in your Government Gateway account (your online HMRC account which you set up when registering for self employment).
