Summary: In May 2025, the Goods and Services Tax Network (GSTN) issued several advisories focused on enhancing taxpayer compliance through portal updates and new validations. Key changes include mandatory HSN code reporting in GSTR-1/1A Table 12 based on turnover, with dropdown selection replacing manual entry. Table 13, covering document details, is now compulsory. New validations ensure consistency of B2B and B2C supply values across different tables in GSTR-1/1A. Table 12 enhancements include separate tabs for B2B and B2C summaries, downloadable HSN lists, and a searchable product master. Aadhaar-based biometric verification has been launched nationwide for new GST registrations to curb fraud, requiring applicants to book slots and verify identities at designated centers. Invoice-wise reporting in GSTR-7, earlier scheduled for implementation in January 2025, has been postponed. Refund process updates allow invoice-based claims without linking to specific tax periods for categories such as deemed exports, SEZ supplies, and export of services. Applicants must ensure all due returns are filed, and invoices used in refund applications are locked to prevent reuse. Appeal withdrawal under the Section 128A waiver scheme has been streamlined. If withdrawal is initiated before the issuance of acknowledgment, it is processed automatically; otherwise, it requires approval. Taxpayers are advised to upload supporting screenshots showing the appeal status. Lastly, while auto-populated values in Table 3.2 of GSTR-3B were expected to become non-editable from April 2025, GSTN has deferred this change, allowing taxpayers to manually adjust the data for now. Taxpayers will be notified before final implementation. These updates aim to simplify compliance and improve accuracy in GST return filing.

- Advisory on HSN Codes and documents

Advisory on refund filing process for recipients of deemed exports
The GSTN has issued an update in relation to changes in refund filing process under the category “on account of refund by recipient of deemed export”.
- Refund applications under this category no longer needs to be filed in chronological order of Tax Period which means taxpayers are not required to select “From Period” and “To Period” while filing refund application.
- However, taxpayers must ensure that all the returns (GSTR-1, GSTR-3B etc) due till the date of refund application, are filed.
- Under this category, the table “Amount Eligible for Refund” has been modified. The columns of the revised table are explained hereunder:
- 1 ‘Balance in ECL at the time of filing of refund application’. This column will reflect the balance available under various Head in Electronic Credit Ledger at the time of filing of application. It will be auto populated.
- 2 ‘Net Input Tax Credit (ITC) of Deemed Exports (as per uploaded invoices)’,in this column the amount of claimed ITC, under respective major Heads will be auto populated based on invoices furnished in Statement 5B.
- 3 ‘Refund amount as per the uploaded invoices’ reflects the sum of the amount of ITC claimed under all major Heads (IGST/CGST/SGST/UT) as per the invoices uploaded by the taxpayer in Statement 5B and shall be downward editable.
- 4 ‘Eligible Refund Amount’. In this column, maximum amount of ITC which is available for refund claim will be auto populated. It will be auto-calculated based on the order of debit specified in Circular No. 125/44/2019-GST dated 18.11.2019.
- 5 “Refund amount not eligible as insufficient balance in the ECL (5)”. This column reflects the difference between the total amount of claimed ITC and the total amount of ITC available in Electronic credit Ledger under various major heads.
- This functionality has been improved to maximize the amount of refund a taxpayer can claim in terms of uploaded invoices, irrespective of the fact that sufficient balance is available in the respective Head of electronic credit ledger or not. Here, the total amount of claim under various Heads (IGST, CGST,SGST) will be compared with total amount of ITC available under various heads in electronic credit ledger, simplifying the refund process.

Appeal withdrawal under GST Waiver Scheme
- GSTN has issued an advisory on Appeal withdrawal with respect to Waiver scheme under section 128A of CGST Act, 2017
- Waiver scheme under Section 128A mandates that any appeal against the requisite demand order should not remain pending with Appellate authority.
- In the GST system, when Appeal Withdrawal Application (APL 01W) for appeal is filed before issuance of final acknowledgment (APL 02) by the Appellate authority, then the system automatically withdraws the Appeal Application (APL 01). In such cases, the status of the appeal application will automatically change from “Appeal submitted” to “Appeal withdrawn”.
- However, if withdrawal application is filed after issuance of final acknowledgment, then the withdrawal of such appeal is subjected to the approval of the Appellate authority. Once the Appellate authority approves the withdrawal application, the status of the Appeal application changes from “Appeal submitted” to “Appeal withdrawn”.
- In both the above-mentioned cases, the status of the Appeal application is changed to “Appeal Withdrawn” which essentially fulfilled the requirement.
- It is advised by GSTN that while filing waiver application or in the already filed waiver application, taxpayers need to upload the screenshot of the appeal case folder showing status as “Appeal withdrawn”.
