“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 … 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. … 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. … given the structure of the default surcharge regime … this is likely to occur only in a wholly exceptional case, dependent upon its own particular circumstances … we cannot ourselves readily identify common characteristics of a case where such a challenge to a default surcharge would be likely to succeed … whilst it might be tempting to seek to isolate, and thus confine, cases by reference to particular criteria, such cases, by reason of their exceptional nature, are likely to defy such characterisation.”
“The correct approach is to determine whether the penalty goes beyond what is strictly necessary for the objectives pursued by the default surcharge regime, as discussed in detail in Total Technology and whether the penalty is so disproportionate to the gravity of the infringement that it becomes an obstacle to the achievement of the underlying aim of the directive which, in this context, we have identified as that of fiscal neutrality”
“[the] 'reasonable excuse' exception strikes a fair balance. The gravity of the infringement is reflected in the absence of 'reasonable excuse' and the amount of the penalty reflects the extent of the default, that is to say the amount of tax not paid by the due date.”
