“The failure to provide HMRC with a certificate of taxable status by the deadline (the end of 2007) means that Lockton did not submit a valid application within time. The claim was not made under Regulation 191(1) unless and until all the documents required by Part XXI of the VAT Regulations are provided; that did not happen prior to the deadline date for making the claim. Consequently HMRC were, we think, correct in law in refusing the application.”
