Obtaining Unique Taxpayer Reference’s (UTR)

5 May 2025

Please see the following message, which we are sharing on behalf of HMRC:

"We’ll shortly be making a service change as part of our ongoing commitment to ensure that we keep our customer data secure. From 6 May, we will no longer provide Unique Taxpayer Reference’s (UTR) over the phone.  

Customers will be able to find their UTR at the top of the home page on their Personal Tax Account. If they don’t have online access, they will be able to find their UTR at the top of any Self Assessment letter that we have sent them. If a customer cannot obtain the UTR by these methods, we will send it to them by post after they have successfully answered a series of security questions.  

Agents that call on behalf of their client will also be advised of where the client’s UTR can be found. If it’s not possible to retrieve the UTR from those sources, then we will issue a letter direct to the agent’s client. The letter can take up to two weeks to arrive.  

We will be publishing an article about these changes in Agent Update on 15 May. In the meantime, please do share this change with your members.”
