How to get my UTR number?

Your UTR is a Unique Taxpayer Reference. It consists of ten digits (sometimes with a letter K at its end) and is issued to you by HMRC.

I think I lost it - where to find it?

If you have registered for self assessment in the past with HMRC you can find your UTR number.

  1. On the front page of previous your tax returns
  2. On any Self Assessment documents HMRC has sent you such as notices to file a return and payment reminders
  3. In your online government gateway account under "self assessment" section.

I've never had it - how to get it?

You can get it by registering for self assessment at HMRC. The process consists of 4 key steps.

Before you start make sure you have your National Insurance number to hand.

  1. Register for HMRC's online service at the Government Gateway.
  2. Then use the service to enroll for self assessment
  3. After enrollment HMRC will send your UTR activation code in the post
  4. Activate your UTR number using the activation code.

HMRC says your UTR activation code will arrive via post within 8 weeks. In our experience it happens much faster. It is important to remember that once you have the code you have 28 days to use it for UTR activation.
