HMRC guidance on identifying genuine email communications
HMRC has updated its guidance on identifying genuine email communications sent to taxpayers and agents. The information outlines various categories of official correspondence, including topics such as Anti-money laundering supervision, Child Benefit claims, and the mandatory tax adviser registration for Corporation Tax. The guidance clarifies that legitimate emails from HMRC will never request personal or financial information, except where specific administrative processes are involved.
What it means for a practice
- Staff should be aware of the specific HMRC email subjects listed, such as those regarding Mandatory Tax Adviser Registration (MMTAR) for agent services accounts.
- Use this list to verify the legitimacy of emails received by the firm or forwarded by clients to protect against phishing attempts.
- Remind clients that while HMRC uses email for informational updates and service prompts, they will not ask for sensitive personal or financial data via these channels.
