IGST reimbursement for manufacturers enables partial refund for interstate supplies, subject to registration, quarterly claims and compliance. SRO-431 creates a state scheme reimbursing part of IGST paid on interstate supplies by manufacturing units in J&K from 01.04.2018, limited to units registered under the J&K VAT Act as of 07.07.2017 and registered with the Department of Industries/Handicrafts/Handloom, excluding goods in Annexure A.

Applicants must submit prescribed registration documents, a declaration and an affidavit cum indemnity bond; inspections, provisional payments, and stipulated recovery procedures with interest apply for misdeclaration or noncompliance.
