Finding your UTR number

Last updated: 08 Jun 2020

You would automatically be sent a Unique Taxpayer Reference (UTR) when you registered as a self-employed person or for self-assessment.

You can also find your UTR in your Personal Tax Account

It’s a 10-digit number; it might also be called ‘tax reference’.

Your UTR number will be on any letter that HMRC sends you.
