Christopher Diball v The Commissioners for HMRC

28 July 2023
[2023] UKFTT 657 (TC)
First-tier Tribunal
Mr. Diball forgot to tell the taxman about extra tax he owed. He said he didn't know about the rule, but the judge said that's not a good enough excuse, so he still has to pay the penalty.

Key Facts

  • Mr. Diball failed to notify HMRC of his liability to the Higher Income Child Benefit Charge (HICBC) for the tax year 2018/19.
  • HMRC sent Mr. Diball a letter on June 11, 2021, informing him of his liability and the potential penalty.
  • Mr. Diball claims he did not receive an awareness letter from HMRC in December 2019.
  • HMRC assessed a 20% penalty (£357.60) for failure to notify.
  • Mr. Diball appealed the penalty, arguing he had a reasonable excuse due to lack of awareness of the HICBC.

Outcomes

Appeal dismissed; penalty upheld.

The Tribunal found that Mr. Diball did not have a reasonable excuse for failing to notify his HICBC liability. While he did not receive the initial awareness letter, ignorance of the law does not constitute a reasonable excuse. His cooperation with HMRC was deemed 'prompted', resulting in a lower penalty than it could have been.
