“Section FRS 3300 of the FRS guidance states ‘The policy is to refuse retrospection where the business has already calculated its VAT liability for the period(s) using a different accounting method. The reason for this is that FRS exists to simplify VAT accounting and record keeping for small businesses, so that they are able to spend less time on VAT’. Section FRS 3300 of the guidance also states ‘In line with the rationale of the Scheme the fact that a business will pay, or would have paid, less tax, is not sufficient reason to authorise retrospective use of the FRS’. Where a trader has already calculated their VAT liability using normal accounting, retrospective use of the Flat Rate Scheme would be authorised only where justified by exceptional circumstances. In your letter you stated ‘My Client had reclaimed VAT on what turned out to be bogus traders and the total liability was£2,652.42 .’ The fact that your Client’s business would have paid less tax is not sufficient reason to authorise retrospective use of the FRS.”
