“The issue arises as to whether reliance on a third-party is prevented from being a reasonable excuse. For VAT purposes there is specific provision that where "reliance is placed on any other person to perform any task, neither the fact of that reliance nor any dilatoriness or inaccuracy on the part of the person relied on is a reasonable excuse." There is also specific provision that insufficiency of funds is not a reasonable excuse (see section 71 VATA). … There is no equivalent provision that reliance on a third party is not a reasonable excuse for direct tax purposes. Whilst in the VAT context it was thought necessary to exclude reliance on a third party as presumably otherwise it could be a reasonable excuse in the direct tax context it is, at most only a indication that reliance on a third party can be a reasonable excuse. However, I consider it a very telling indication especially as it is a limited exclusion for VAT (see Enterprise Safety Coaches notwithstanding GB Capital Ltd). The Thorne case and Enterprise Safety Coaches are clear authority that reliance on a third party can be a reasonable excuse. I conclude that in the direct tax context reliance on a third party can be a reasonable excuse.”
