I agree that s.12D TMA 1970 provides an alternative to notification by 5 October in delivering a ‘purported return’ as described therein by 31 January next following the tax year.
Such a return would give details of income and gains, and the tax liability thereon. However, the information to be provided to the TRS under regulation 45 does not include any details of the tax for which the trustees are liable.
No information supplied to HMRC in their guise as the Tax Registration Service seems be an acceptable alternative to sections 7 or 12D TMA 1970.
