Acknowledgment requirement for VAT returns: coloured triplicate forms determine refund claims and render returns incomplete if absent. Every dealer required to furnish VAT returns must attach an Acknowledgment in triplicate printed on red paper if claiming a cash refund and on green paper if not; each acknowledgment must be signed, fully completed and include departmental receipt number, return period, dealer identification, whether CST and DVAT statements (DVAT-18, DVAT-18A) are enclosed, turnover and tax figures, and, for refunds, detailed bank account information with a cancelled cheque. Any return submitted without the prescribed acknowledgment will be treated as an incomplete return.
