What is a UTR and why do I need a UTR?

Your Unique Taxpayer Reference (UTR) is a number that HMRC uses to identify you for everything to do with your taxes.
If you are or planning to be self-employed it is critical you have a UTR so that you can complete a self-assessment tax return at the end of each tax year (tax years run from 6th April to 5th April the following year).
If you do not complete a self-assessment HMRC will apply fines to your account.
