Can I find my UTR number online?

I have researched and compiled information on finding your UTR number online. The Unique Taxpayer Reference (UTR) number is a 10-digit code assigned to individuals or businesses in the United Kingdom for tax purposes. It is a unique identifier that helps in filing tax returns, interacting with HM Revenue and Customs (HMRC), and managing your tax affairs.

While many aspects of tax management can be done online, unfortunately, the process of finding your UTR number is not one of them. The HMRC does not typically provide UTR numbers online for security reasons. However, there are alternative methods to obtain your UTR number.

Method 1: Checking your UTR number on previous tax documents

If you have filed a tax return before or have any other correspondence from HMRC, your UTR number should be mentioned on these documents. It is usually indicated at the top or bottom of the document and can be identified as 'UTR' or 'Tax Reference' followed by 10 digits. Keep in mind that these documents should be kept safe and accessible for future reference.

Method 2: Contacting HMRC

If you cannot find your UTR number on any of your tax documents, you can contact HMRC directly to obtain it. The general contact number for individuals in the UK is 0300 200 3310, and for businesses, it is 0300 200 3410. Calling HMRC will require you to provide relevant personal and business information to verify your identity. Once your details are confirmed, a representative will assist you in retrieving your UTR number.

Method 3: Requesting a UTR number online

In some cases, individuals or businesses may not have previously been issued a UTR number. If this is your situation, you can request a UTR number online by completing the HMRC form SA1. This form is for individuals and partnerships and should be submitted to HMRC for processing. However, it is important to note that this method may require additional time for your application to be processed and for you to receive your UTR number.

It is essential to keep your UTR number secure

After obtaining your UTR number, it is crucial to keep it safe and secure. Your UTR number is confidential information that should not be shared with anyone else unless necessary for tax-related purposes. Failure to protect your UTR number could lead to potential identity theft, fraud, or unauthorized access to your tax information.


While you cannot find your UTR number online due to security reasons, you can obtain it through alternative methods. Checking previous tax documents, contacting HMRC directly, or requesting a UTR number online are the three main options available. Make sure to keep your UTR number confidential to protect your tax information and minimize the risk of unauthorized access.

Remember, if you have any concerns or questions regarding your UTR number or tax matters, it is always a good idea to consult with a tax professional or seek guidance from HMRC directly.
