Unique Tax Reference (UTR) number

IN THIS ARTICLE:

What is a UTR?

A Unique Tax Reference number (UTR) is made up of 10 numbers and is posted by HM Revenue and Customs to you when your company has been incorporated. The UTR is used to file your Self Assessment Tax Returns. 

When is it needed?

You will need your UTR number to register for corporation tax within 3 months of starting doing business, such as buying, selling, advertising, etc. You will also need it when you file Self Assessment Tax Returns to HMRC.

Where can I find my UTR number?

You will need a UTR number to register for corporation tax within 3 months of starting doing business, such as buying, selling, advertising, etc. You will also need it when you file Self Assessment Tax Returns to HMRC.

Once a limited company has been formed, Companies House will notify HMRC of the company’s incorporation. Roughly three weeks after your company's incorporation, HMRC will send you a letter to your registered office explaining what the company needs to do next, in this letter you will find the “Unique Tax Reference” or “UTR”.   

If you purchase one of our company formation packages that contain our London Registered Office Service, HMRC will automatically send the UTR letter to this registered address within three weeks of your company's incorporation date. When we receive the letter, we will then forward it to your home address.

Please note: we do not hold details of your UTR number.

Lost or did not receive your UTR number?

If you do not receive your UTR within 3 weeks of incorporation call one of the following:

  • UK: 0300 200 3410
  • Outside UK: +44 151 268 0571

HMRC will then resend the UTR to the Registered Office – they will not be able to give it to you over the phone.
