What is a UTR?

UTR stands for Unique Taxpayer Reference.  Your UTR is a unique number that identifies you to HMRC.  It is sometimes referred to as just "Taxpayer Number".  Businesses and individual taxpayers have one.

What do I need it for?

You need a UTR in order to complete your tax return.  Even if you don't need to complete a tax return you might need one if you ask an accountant or tax advisor to help with your financial affairs. 

In order to submit your tax return from the untied app you will need to enter your UTR number along with your Government Gateway ID.

Where do I get one from?

Your UTR number is assigned automatically by HMRC when you register for self assessment tax returns.  If you're already registered you'll find it in one of the following places:

  • In your "A Welcome to Self-Assessment" letter (SA250).
  • In your Self Assessment tax return.
  • In your notice to File a Tax Return.
  • In your Statement of Account and payment reminders.

If you aren't yet registered for self assessment you will need to do so if you need to submit a tax return. You can do that here on the HMRC website.
