Longer Answer:  HMRC should have been sent a UTR number when you:

If you have lost this document, you can find your UTR number on a number of other letters that HMRC would send to you including:

  • Your Tax return

  • Your Statement of Account

  • Any Tax Payment Reminders

  • A Notice to File a Tax Return

How long does it take to get a UTR Number?

Short Answer: 10 days after you register

Longer Answer:  If you complete the registration correctly and with no issues then it should take 10 days to receive your UTR Number.

For some people, it can be quicker to use an accountant to get your UTR Number as they know what they are doing and complete the process many times before and are less likely to make a mistake.

If you are applying from abroad it will take 21 days to get your UTR Number. 

This is another reason why people opt to have someone help them to get their UTR Number.

Is it OK to give out my UTR Number?

Short Answer: Yes

Longer Answer:  It is always a good idea to be cautious with your personal information.

Don't post your UTR Number publically on the internet or somewhere where anyone can see it.

If however, it is common for your employer to ask for your unique taxpayer reference number so that they can verify that you are self-employed or a subcontrator.
