“For the purposes of any provision of sections 59 to 70 which refers to a reasonable excuse for any conduct- (a) an insufficiency of funds to pay any VAT due is not reasonable excuse; and (b) where reliance is place 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 upon is a reasonable excuse.”
“if the exercise of reasonable foresight and of due diligence and a proper regard for the fact that the tax would become due on a particular date would not have avoided the insufficiency of funds which led to the default, then the taxpayer may well have a reasonable excuse for non-payment, but that excuse will be exhausted by the date on which such foresight, diligence and regard would have overcome the insufficiency of funds.”
“65. We agree with the tribunal in Total Technology that the default surcharge regime, viewed as a whole, is a rational scheme. The penalties are financial penalties, calculated by reference to the amount of tax unpaid at the due date. Although penalties may vary with the liability of the taxable person for the relevant VAT period, and increase commensurately with an increase in such liability (and, consequently, such default), the penalties are not entirely open-ended. The maximum liability for a fifth or subsequent period of default is 15% of the amount unpaid. In common with the Upper Tribunal in Total Technology , we consider that the use of the amount unpaid as the objective factor by which the amount of the surcharge varies is not a flaw in the system; to the contrary, the achievement of the aim of fiscal neutrality depends on the timely payment of the amount due, and that criterion is therefore an appropriate, if not the most appropriate, factor. 66. However, we accept that, applying the tests we have described, the absence of any financial limit on the level of surcharge may result in an individual case in a penalty that might be considered disproportionate. In our judgment, given the structure of the default surcharge regime, including those features described in Total Technology , this is likely to occur only in a wholly exceptional case, dependent upon its own particular circumstances. Although the absence of a maximum penalty means that the possibility of a proper challenge on the basis of proportionality cannot be ruled out, we cannot ourselves readily identify common characteristics of a case where such a challenge to a default surcharge would be likely to succeed.”
