Find your UTR number

You get a Unique Taxpayer Reference (UTR) when you:

  • register for Self Assessment
  • set up a limited company

It’s a 10-digit number. It might just be called ‘tax reference’.

You’ll get your UTR by post 15 days after you register. It takes longer if you live overseas.

This guide is also available in Welsh (Cymraeg).

Where to find your UTR

How you find your UTR depends on your circumstances.

If you’re an individual or sole trader

You can find your individual UTR number:

  • in your Personal Tax Account
  • in the HMRC app
  • on previous tax returns and other documents from HMRC (for example, notices to file a return or payment reminders)

If you cannot find your UTR on any documents or online, contact HMRC.

If you’re acting on behalf of an organisation (for example, a company, partnership or trust)

You can find the organisation’s UTR number on previous tax returns and other documents from HMRC (for example, notices to file a return or payment reminders).

If you cannot find the organisation’s UTR on any documents or online, contact HMRC.

If you have a limited company

You can request your Corporation Tax UTR online. HMRC will send it to the business address that’s registered with Companies House.
