“(1) The Commissioners (HMRC) may by regulations make provision under which, where a taxable person so elects, the amount of his liability to VAT in respect of his relevant supplies in any prescribed accounting period shall be the appropriate percentage of his relevant turnover for that period. … (6) The regulations may (a) provide for the appropriate percentage to be determined by reference to the category of business that a person is expected, on reasonable grounds, to carry on in a particular period;”
“(1) The appropriate percentage to be applied by a flat rate trader for any prescribed accounting period, or part of the prescribed accounting period (as the case may be), shall be determined in accordance with this regulation and regulations 55JB and 55K (2) For any prescribed accounting period- (a) beginning with a relevant date, the appropriate percentage shall be that specified in the Table for the category of business that he is expected, at the relevant date, on reasonable grounds, to carry on in that period.”
“(1) Subject to sections 83G and 84, an appeal shall lie to the tribunals with respect to any of the following matters … (fza) a decision of [HMRC]… (ii) as to the appropriate percentage or percentages (within the meaning of that section) applicable in a persons case”
“(4ZA) Where an appeal is brought (a) against such a decision as is mentioned in [Section 83(1)(fza)], or (b) to the extent that it is based on such a decision, against an assessment, the tribunal shall not allow the appeal unless it considers that [HMRC] could not reasonably have been satisfied that there were grounds for the decision.”
“The flat rate you use depends on the business sector that you belong in. All the sectors can be found at the link in paragraph 4.3. The correct sector is the one that most closely describes what your business will be doing in the coming year. Sections FRS7200 and FRS7300 of the Flat Rate Scheme Guidance show you which businesses we think belong in each sector… We will not normally check your choice of sector when we process your application. So if you have made a mistake you may pay too much tax or too little. Paying too little could mean that you are faced with an unexpected VAT bill at a later date. However, if we approve you to join the scheme we will not change your choice of sector retrospectively as long as your choice was reasonable… Note: Some business activities can reasonably fit into more than one sector. So changing your sector does not automatically make your original choice unreasonable.”
“We note the wording of regulation 55K(4). The category proposed by HMRC refers to civil and structural engineers. That term whether read alone or in context with ‘architects’ and ‘surveyors’ denotes in our view operations relating to land, buildings and other structures. We consider that mechanical engineering is a distinct field. The adjectives, civil and structural, were, we must assume, chosen consciously and deliberately by the draughtsman. It is, we think well within judicial knowledge that there is an obvious defining line between mechanical engineering and the other two categories of engineering activity mentioned.”
