UK Adds Joint Account Reporting

On December 4, 2025, the United Kingdom HMRC published an update to the International Exchange of Information Manual “Reportable Information: Joint Accounts”. Commencing with reporting on Y2026 data to be submitted in 2027, Financial Institutions (FIs) must identify if Reportable Accounts are joint accounts. If yes, then the number of joint account holders must be reported.

Additionally, if a new joint account holder is added to a pre-existing account, the FI is required to undertake New Account due diligence on the new joint account holder.
