In a bid to make the GST refund system more automated, the government is introducing an Annexure-B offline utility in place of the earlier PDF-based Annexure-B in Form GST RFD-01, making the refund filing process more streamlined, structured and system-driven.
With this enhancement, businesses claiming GST refunds on unutilised Input Tax Credit (ITC), particularly exporters and taxpayers operating under an inverted duty structure, are expected to benefit from improved data accuracy, faster processing and greater transparency in refund applications. The revised utility is also likely to enable stronger system-based validation and reduce manual intervention, thereby improving efficiency and ensuring smoother processing of refund claims.
Under the revised procedure, taxpayers filing refund applications for accumulated ITC will now have to prepare Annexure-B using an offline utility and upload it in JSON format along with FORM GST RFD-01.
The updated utility now requires taxpayers to furnish significantly more detailed information for every invoice included in the refund claim.
This includes the nature of inward supply, type of document, total ITC claimed, whether any portion falls under blocked credit rules under Section 17(5), eligible and ineligible ITC amounts, and the relevant GSTR-2B period in which the invoice appears.
Under the revised system, the GST portal itself may begin validating invoices and ITC details at the filing stage through automated checks.
For businesses, particularly exporters that depend heavily on timely GST refunds for working capital, the changes increase the importance of accurate reconciliations and clean vendor data.
Companies may now need to undertake more detailed matching of purchase registers, GSTR-2B records, electronic credit ledger balances and refund workings before filing claims.
Even minor errors — such as claiming blocked credit, reporting an incorrect GSTR-2B period or mismatches in invoice details — could trigger system flags, additional scrutiny or delays in refund processing.
The impact is expected to be more significant for businesses with large procurement volumes and multiple vendors, where reconciliation gaps are more common.
