UTR Number

All you need to know about & how to apply for your UTR number

A UTR (Unique Taxpayer Reference) number is a 10 digit number that is unique to either you or your company, sometimes with a letter ‘K’ on the end. On some HRMC documents it might just be called a ‘tax reference’.

Lost your UTR number?

Your UTR number is on previous tax returns and other documents from HMRC, for example:

  • Notices to file a return
  • Payment reminders
  • Your “Welcome to self assessment” letter (SA250)
  • Your self assessment tax return
What if you still can’t find your UTR number

Call the Self Assessment helpline if you need your UTR number and can’t find any documents from HMRC.

The UTR number can take a while to come through the post so make sure you leave enough time to apply (we suggest, 2 months in advance) so you can meet the filing deadline of 31st January. HMRC recommend you give yourself at least 4 weeks to receive your UTR number.

If you have recently become self employed, then you may need to apply for a UTR (Unique Tax Reference) number from HMRC. It is important to make sure that you have registered and have all the correct paper work as it is your responsibility to ensure your status is correct.

If you are a subcontractor, take your new UTR number to your contractors, you will then be charged 20% tax, rather than the 30% emergency tax rate you will currently be paying. If you decide to use Rebate My Tax Ltd to perform your self assessment, we can ensure you get back any excess tax you have paid, ensuring you get back what is rightfully yours.
