Sch 11 para 2B
(1) This paragraph applies where a taxable person provides to himself a document (a “ self-billed invoice ”) that purports to be a VAT invoice in respect of a supply of goods or services to him by another taxable person. (2) Subject to compliance with such conditions as may be— (a) prescribed, (b) specified in a notice published by the Commissioners, or (c) imposed in a particular case in accordance with regulations, a self-billed invoice shall be treated as the VAT invoice required by regulations under paragraph 2A above to be provided by the supplier. (3) For the purposes of section 6(4) (under which the time of supply can be determined by the prior issue of an invoice) a self-billed invoice shall not be treated as issued by the supplier. (4) For the purposes of section 6(5) and (6) (under which the time of supply can be determined by the subsequent issue of an invoice) a self-billed invoice in relation to which the conditions mentioned in sub-paragraph (2) are complied with shall, subject to compliance with such further conditions as may be prescribed, be treated as issued by the supplier. In such a case, any notice of election given or request made for the purposes of section 6(5) or (6) by the person providing the self-billed invoice shall be treated for those purposes as given or made by the supplier. (5) Regulations under this paragraph— (a) may be framed so as to apply only in prescribed cases or only in relation to supplies made to persons of prescribed descriptions; (b) may make different provision for different circumstances.
