UTR (Unique Tax Reference) numbers will no longer be available by phone from HMRC.

HMRC have said that as of 06 May 2025 they will no longer confirm UTR numbers to taxpayers or agents via telephone. This is part of a move to increase the security of taxpayer data.

Instead, UTRs will be available through taxpayer’s individual online accounts or via the HMRC app. The 10-digit Unique Tax Reference number is needed to file Self Assessment and to communicate with HMRC.

HMRC have said: ‘We’ve made this change to help keep people’s data secure. Customers still can find their Unique Taxpayer Reference in their online account and on previous self assessment letters. We can also send new letters to customers who call us once we have verified their identity.’

Agents can request a letter on a client’s behalf or the taxpayer can request it themselves. HMRC have indicated that taxpayers will need to answer some security questions in order for the letter to be issued.

Letters from HMRC confirming the UTR number can take up to two weeks to arrive. Taxpayers should ensure that they have this information available prior to deadlines and busy time of year, such January which is the deadline for filing Self Assessment Tax Returns.

Further guidance is expected from HMRC in due course.
