“45. Whilst we can understand why Mr and Mrs Simmonite might have a genuine belief that notification to HMRC's Child Benefit Office satisfied any obligation they might have to notify HMRC, we find that – as a matter of strict law – it did not. The notification made on the phone by Mrs Simmonite to the Child Benefit Office was to stop payment of child benefit. We find that Mrs Simmonite told the officer to whom she spoke that she stopped her claim because of a liability to HICBC. However, we find that notification to the Child Benefit Office cannot be treated as notification to HMRC for the purposes of s7 TMA . HMRC undertakes a wide range of functions, some of which do not relate to the assessment and collection of tax (such as the administration of child benefit, SMP and SSP, and childcare payments). Given this wide range of functions, we find that notification under s7 can only be treated as effective if made to the correct department within HMRC.”
