About a UTR

Your UTR is your unique taxpayer reference and is a ten digit code that HMRC uses to identify you.

You'll get a UTR when you register for self assessment. If you need help registering, you can do that by clicking here.

Sometimes HMRC or others may refer to it as a tax reference or a personal tax reference. Don't confuse it with your national insurance number (also called an NI number or NINO), which is a mix of letters and numbers.

Your UTR is a very important reference - it can be used to make filings to HMRC on your behalf. You will be able to find it in your HMRC personal tax account - and if you're an untied user, it will be in your profile screen.

How do I find my UTR?

  • Check on documents that HMRC have sent to you, as they often include it
  • Take a look for it on previous tax returns you have filed
  • If you have an HMRC log in, you can find this number in your personal tax account.

In some places, you may see the letter "K" after the UTR. This does not form part of your UTR but is used by HMRC for some payment references.

You can use untied to pay HMRC. We make it simple, quick and easy because your UTR and payment reference will automatically be populated in the untied app.

If your UTR looks like it's 13 digits long, then only include the last ten digits.
