GSTN Automated Annexure-B Validation Utility for GST Refund Applications (RFD-01)
The Goods and Services Tax Network (GSTN) has introduced a major change in the GST refund filing process by implementing an automated validation utility for Annexure-B (Input Tax Credit Statement) to be filed along with Form RFD-01. Earlier, taxpayers and professionals were preparing Annexure-B manually in PDF or Excel format and uploading it as a supporting document with the refund application. However, under the revised mechanism, Annexure-B is now required to be prepared through the prescribed validation utility and uploaded in JSON format, which gets directly integrated with the refund application on the GST Portal.
This change is not merely a shift from PDF to JSON format, but a complete transition toward a system-driven and validation-based refund processing mechanism. The new utility performs automated checks and validations before allowing submission of refund data. Through this process, GSTN intends to increase transparency, reduce manual scrutiny, and improve accuracy in GST refund claims.
Under the updated utility, several additional reporting parameters have been introduced. Taxpayers are now required to separately disclose blocked Input Tax Credit under Section 17(5) of the CGST Act. Further, the utility mandates bifurcation between eligible and ineligible ITC, which has increased the importance of detailed reconciliation between books of accounts, GSTR-2B, and GSTR-3B. Another important requirement introduced is invoice-wise disclosure of the relevant GSTR-2B period in which the invoice is reflected. This has made vendor compliance and invoice tracking significantly more important for taxpayers claiming refunds.
GSTN has also introduced separate reporting tables for reversals under Rule 38, Rule 42, Rule 43, and Section 17(5) of the CGST Act. Additionally, a separate reporting table for “Other Reversals” has been incorporated into the utility. These additional disclosures indicate that GSTN is moving toward a more detailed and data-centric refund verification framework.
While the new automated utility is a positive step toward digitization and streamlined processing, it has also increased the compliance burden on taxpayers and professionals. Businesses are now required to maintain detailed invoice-level reconciliations, accurate ITC classifications, and proper vendor-wise data management to avoid validation failures and refund objections.
Overall, the introduction of the automated Annexure-B utility marks a significant technological advancement in the GST refund ecosystem. Although taxpayers may initially face practical and operational challenges, the new system is expected to improve the efficiency, transparency, and reliability of refund processing in the long run.
