HMRC have issued the latest round of One-to-Many letters. It is aimed at tax agents submitting multiple P11D and P14 claims for clients where there may be a subsequent discrepancy on their 2021-22 Self Assessment Tax Return in relation to the High Income Child Benefit Charge (HICBC).

  • The nudge letters are being sent by the HMRC Agent Compliance Team throughout the month of October.
  • The P11D and P14 claims may highlight where an individual has an Adjusted Net Income of over £50,000 but no notice has been given of a liability to the HICBC.
  • The letters will be followed up by HMRC to discuss potential charges and how errors can be amended, outside of the scope of a formal enquiry.
  • The deadline for amendments to the 2021-22 tax return is 31 January 2024.
  • Any voluntary amendments entered into as a result of the letters will not attract any penalties.
  • If no amendments are made where they should have been, Discovery Assessments and Penalties may be imposed.
