3. Payment of ST/VAT by utilizing the input tax credit :- In terms of the requirement under Para 2(d) of the said notification, appropriate ST/VAT is to be paid by the importer on sale of goods. It is noticed that most of the ST/VAT legislations provide for payment of ST/VAT by utilizing the input tax credit. If the Sales Tax Authorities accept payment of ST/VAT through cash or adjustment of input tax credit, the same shall be treated as effective discharge of ST/VAT payment on imported goods.
Further, it was provided in Board’s Circular No.16/2008 –Cus dated 13-10-2008 that a certificate from Statutory Auditor/Chartered Accountant correlating the payment of ST/VAT on the imported goods with the invoices of sale, along with supporting documents of proof of payment of appropriate ST/VAT is acceptable for the purpose of 4% SAD refund.
