All MTD updates

Guidance on genuine HMRC communications using multiple channels

HMRC has updated its guidance regarding instances where the department uses multiple communication methods to contact taxpayers and agents. This includes letters, emails, phone calls, or text messages. The page lists specific active research projects and administrative processes where HMRC or independent agencies like IFF Research and Verian may reach out to businesses and representatives. The information aims to help verify the legitimacy of these contacts and avoid potential scams.

What it means for a practice

  • You may be contacted by IFF Research via letter, email, or phone regarding surveys on your experience as an agent working with HMRC.
  • If you or your clients receive unexpected contact, check this list to verify if the outreach is part of a current HMRC research project or administrative process.
  • Remind clients that they may be contacted through various channels for specific updates, such as changes to tax codes or complaints handling, but that genuine HMRC outreach will not request personal financial information in most of these specific scenarios.
