"First, whether the assessment has been made under the power conferred under that section; and, second, whether the amount of the assessment is the correct amount for which the taxpayer is accountable."
"The explanation may be that the tribunal, applying its own judgment to the same underlying material at the second, or 'quantum', stage of the appeal, has made different assumptions - say, as to food/drink ratios, wastage or pilferage - from those made by the commissioners. As Woolf J pointed out in Van Boeckel ([1981] STC 290 at 297), that does not lead to the conclusion that the assumptions made by the commissioners were unreasonable; nor that they were outside the margin of discretion inherent in the exercise of judgment in these cases. Or the explanation may be that the tribunal is satisfied that the commissioners have made a mistake - that they have misunderstood or misinterpreted the material which was before them, adopted a wrong methodology or, more simply, made a miscalculation in computing the amount of VAT payable from their own figures. In such cases - of which the present is one - the relevant question is whether the mistake is consistent with an honest and genuine attempt to make a reasoned assessment of the VAT payable; or is of such a nature that it compels the conclusion that no officer seeking to exercise best judgment could have made it. Or there may be no explanation; in which case the proper inference may be that the assessment was indeed arbitrary."
“ Please cancel the above registration as continued ill health makes it impossible for me to continue working. ” 16. Mr Rush attended at 10 Blenheim Gardens on13 December 2007 . He was advised by the occupant that she had just bought the house and gave a forwarding address called Garden View in Morpeth. She also provided a mobile phone contact number. Mr Rush attempted to find that address without success. However Mr Rush was able to speak with Mr Dockett by phone and was told that he would be in Spain for the next couple of months. 17. In February 2008 an officer again contacted Mr Dockett by phone and was told that he was still in Spain and was unsure where the business records were. She was also told that Garden View was where Mr Dockett’s son lived. Mr Dockett was given 3 weeks in which to produce the business records. 18. The business records were not produced and on19 March 2008 HMRC wrote to Mr Dockett at Garden View seeking to arrange an appointment for Mr Rush to visit on1 April 2008 to inspect the business records at Garden View. Mr Dockett did not respond or make himself available on1 April 2008 . 19. On14 April 2008 HMRC wrote to Mr Dockett, this time at the Pegswood address. The letter was copied to Garden View and enclosed a schedule of the VAT considered to be due for periods 05/05 to 11/07. The letter indicated that an assessment would follow in due course. 20. On25 April 2008 “ Notice of Assessment(s) ” was sent to Mr Dockett at the Pegswood address. The total VAT assessed was£105,876 . Mr Dockett states that he did not receive the Notice and we accept that evidence. 21. At some stage thereafter the Assessments were passed to the HMRC debt management office which also sought assistance from the Spanish Authorities in enforcing the debt. The evidence before us showed a letter dated20 October 2009 to Mr Dockett at an address in Tarragona, Spain. The unpaid amount, presumably including interest, was£155,050 . Mr Dockett replied by an undated letter which was received by HMRC on4 November 2009 . He expressed surprise at having received the letter and said “ …when I left the UK as far as I knew I owed you nothing … When I left the UK I meant to inform you that I had ceased trading but was not fully compos mentos due to high levels of prescription drugs … ”. 22. There was then further correspondence and a period of delay on the part of HMRC before notices of the assessment were sent to Mr Dockett in Spain on24 August 2010 . This letter was not returned to HMRC and we find on the balance of probability that Mr Dockett first became aware of the actual Assessments at the end of August 2010. There was subsequent correspondence returned undelivered but on9 February 2011 Mr Dockett wrote criticising the Assessments. By that stage he was certainly aware of the basis on which the Assessments had been made. (2) Judgment in Making the Assessments 23. HMRC carried out an audit visit on3 May 2005 during which the officer was satisfied as to the zero rating of certain supplies. Since then Mr Dockett had made VAT returns giving rise to quarterly repayments of approximately£3,000 . One of the matters Mr Rush wished to consider at the visit he was seeking to arrange in 2007 was a fall in declared sales from June 2006 onwards which did not seem to reflect in the amount of quarterly repayments. 24. In the absence of any opportunity to inspect the business records or discuss the business with Mr Dockett, Mr Rush made the Assessments in April 2008. He was not satisfied that the business should be in a repayment position. He considered other pet food shops and wholesalers which were all making payment returns. In the circumstances he based the Assessments on the flat rate scheme for “ wholesaling not listed elsewhere ”
