What To Do If You Have Lost Your UTR Number
If you want to file your tax return online, or you have a query about your self assessment tax return, you will generally be asked for your Unique Taxpayers Reference (UTR) number. This is a number that is unique to you and is provided by HM Revenue and Customs (HMRC) when you register for self assessment.
However, it is easy to lose or mislay your UTR number. Our guide gives you advice on where to find your UTR number and who to contact if you lose it.
Your UTR number
A UTR number is a unique number provided by HMRC so that you can complete your tax return. It has ten digits (for example, 64892 13567) and it is used by HMRC to identify you. As it is unique, it makes it easy for HMRC to access your tax affairs when you submit your self assessment tax return or if you have any queries about your tax.
Finding your UTR number
If you can’t remember what your UTR Number is, there are various places where you may be able to find it. These include:
- Your ‘Welcome to Self Assessment’ letter (SA250). This letter explains the importance of the UTR, your need to retain it, store it securely and how it is used by HMRC for reference purposes
- Your tax return – if you have a copy of your tax return, your UTR number should be on this
- Your ‘Notice to File a Tax Return’ – if you submit your tax return online, you will generally receive a reminder that your self assessment tax return is due. This is your ‘Notice to File’. Your UTR number will be found on your Notice to File document
- Your ‘Statement of Account’ – your UTR will also appear on your HMRC statement
You will often also find your UTR number on other HMRC correspondence; for example any payment reminders or other formal letters.
What to do if you have lost your UTR number
If you cannot find your UTR number on any of your HMRC correspondence, you should get in touch with your local Tax Office. Your Tax Office will be able to locate your UTR number for you after you have passed a number of security checks.
For confidentiality and security reasons, your UTR number will be sent to you via the post. You won’t be given your UTR number over the telephone or via fax.
If an agent (an accountant, for example) is dealing with your tax affairs, the same security rules apply. Agents are normally expected to obtain a UTR number from you directly, although there is a dedicated number at HMRC they can call if you do not have lost your UTR number. Agents will have to have formal authorisation from you and pass security checks. Again, the UTR number will be confirmed in writing by post.
