"7. It is increasingly common for HMRC to work enquiries simultaneously across several areas such as income tax, VAT, and employer compliance. That is a sensible approach which attempts to minimise the disruption to a taxpayer’s business by avoiding the same questions being asked on different occasions by separate enquiry teams. However, there are separate legislative provisions applicable to the different types of enquiry and so an application to this Tribunal must be considered in the context of the part of the exercise that is covered by the application. 8. HMRC are investigating Mrs Huan’s tax affairs in relation to income tax, VAT and employer compliance for a period extending over several years. Mrs Huan’s application to this Tribunal is made under s 28A TMA and concerns the s 9A income tax enquiry relating to the tax year 2008-09. 9. From Mrs Huan’s evidence we are unclear what she is prepared to concede concerning unrecorded sales. But from the documents available to us we conclude (a) she has stated to HMRC that the business had been run on the same basis since approximately 2000; and (b) there were unrecorded sales in 2009. From that it is reasonable for HMRC to draw the inference that the turnover shown in the business accounts for periods prior to 2009 (as well as 2009) may be inaccurate. 10. It would not be reasonable for HMRC to contend that the s 9A enquiry must remain open for the duration of HMRC’s investigation of the VAT records of the business. If Mrs Huan could show that the questions being asked by HMRC were not pertinent to her income tax position then HMRC might be in a difficult position in attempting to resist the closure notice application. So if the only open items were related to matters particular to the VAT position of her business – say, whether certain supplies of food were zero rated or standard rated – then we would have some sympathy with her application for the s 9A enquiry to be directed to be closed. However, at least some of HMRC’s unanswered questions fundamentally affect the s 9A enquiry – for example, the accuracy of the turnover stated in the business accounts. We consider that HMRC are not yet in a position to form a judgment about the income tax due for the 2008-09 tax year, and it would be premature to order closure of the enquiry at this time. Accordingly, as communicated to the parties at the conclusion of the hearing, we will refuse the application. 11. It is open to Mrs Huan to make a fresh application for a closure notice in the future. If at that time she has answered all HMRC’s legitimate questions pertaining to her income tax affairs for the 2008-09 tax year then, even if some points peculiar to the VAT enquiry remain open, the Tribunal may be persuaded that it is not reasonable for HMRC to keep open the s 9A enquiry. But that is not the state of affairs as of the date of this hearing."
