At the end of the hearing the Tribunal gave its decision for reasons which now follow. 33. The adverse trading circumstances affecting the Appellant were not in dispute. We were not addressed in relation to the individual defaults, but rather on the defaults as a whole in the context of the Appellant’s trading difficulties. We accept that the Appellant was clearly experiencing financial difficulties over the period of default. However, as stated in paragraph 6(2)(a) of Schedule 56, an insufficiency of funds does not qualify as a reasonable excuse. An inability to pay does not represent special circumstances which might justify a reduction in a penalty. An exceptional or unforeseen event which caused the insufficiency of funds may amount to a reasonable excuse but on the facts of this appeal there was no such event. Something specific, unforeseen and related to the particular tax-payer is required. Adverse economic conditions affecting business activity generally do not suffice. 34. HMRC were not under any statutory duty to warn the Appellant of a change in potential penalties. The legislation does not require HMRC to issue warnings to individual employers. It is settled law that any failure by HMRC to give warning of the penalty regime cannot provide a reasonable excuse. The obligation is to make payment by the due date – see Rodney Warren & Co[2012] UKFTT 57 (TC) and Dina Foods Limited above. 35. The Tribunal is satisfied that there was an extensive campaign of advance publicity and that there was no reason why the Appellant should not have been sufficiently alerted. The Appellant’s apparent lack of awareness of the new penalty regime is not capable of constituting a special circumstance or reasonable excuse. 36. The Appellant would have received an initial Penalty Default Warning letter in May 2011 (which also explained about time to pay arrangements) and subsequent enforcement warning letters. There was a considerable amount of contact with HMRC throughout the year about late payments of PAYE. There were several telephone conversations with representatives of the company. A reasonably prudent employer, aware of its responsibilities to make timely payments of PAYE and NICs amounts, would have been prompted to make enquiries of HMRC to obtain information about the penalty regime. 37. With regard to the issue of proportionality, in Dina Foods , at [40]-[42], the Tribunal considered whether the penalty was disproportionate, and said as follows: ‘40. In its initial appeal letter and in its formal notice of appeal, the company referred to the penalty being excessive. It is clearly not excessive on the terms of Schedule 56 itself because the system laid down prescribes the penalties. Nonetheless, whilst no specific argument was addressed to us on proportionality, we have considered whether, in the circumstances of this case, the 4% penalty that was levied on the total of the relevant defaults in the tax year can be said to be disproportionate. 41. The issue of proportionality in this context is one of human rights, and whether, in accordance with the European Convention on Human Rights, Dina Foods Ltd could demonstrate that the imposition of the penalty is an unjustified interference with a possession. According to the settled law, in matters of taxation the State enjoys a wide margin of appreciation, and the European Court of Human Rights will respect the legislature's assessment in such matters unless it is devoid of reasonable foundation. Nevertheless, it has been recognised that not merely must the impairment of the individual's rights be no more than is necessary for the attainment of the public policy objective sought, but it must also not impose an excessive burden on the individual concerned. The test is whether the scheme is not merely harsh but plainly unfair so that, however effectively that unfairness may assist in achieving the social objective, it simply cannot be permitted. 42. Applying this test, whilst any penalty may be perceived as harsh, we do not consider that the levying of the penalty in this case was plainly unfair. It is in our view clear that the scheme of the legislation as a whole, which seeks to provide both an incentive for taxpayers to comply with their payment obligations, and the consequence of penalties should they fail to do so, cannot be described as wholly devoid of reasonable foundation. We have described earlier the graduated level of penalties depending on the number of defaults in a tax year, the fact that the first late payment is not counted as a default, the availability of a reasonable excuse defence and the ability to reduce a penalty in special circumstances. The taxpayer also has the right of an appeal to the Tribunal. Although the size of penalty that has rapidly accrued in the current case may seem harsh, the scheme of the legislation is in our view within the margin of appreciation afforded to the State in this respect. Accordingly we find that no Convention right has been infringed and the appeal cannot succeed on that basis’
