The Institute of Chartered Accountants of India (ICAI) has released a technical publication titled “Practical FAQs on Filing of Form GSTR-3B”, providing important practical clarifications and compliance guidance on various issues relating to filing of FORM GSTR-3B under the GST regime.
The publication addresses several complex and recurring practical issues faced by taxpayers, professionals, and businesses while reporting Input Tax Credit (ITC), Reverse Charge Mechanism (RCM) liabilities, reclaim of reversed credits, interest computation, and reconciliation challenges in GST returns.
Clarifications on ITC Reversal and Reclaim Mechanism
One of the major highlights of the publication is detailed clarification regarding reporting of temporary and permanent ITC reversals in Table 4(B)(1) and Table 4(B)(2) of FORM GSTR-3B.
ICAI clarified that:
- Table 4(B)(1) is intended exclusively for permanent and non-reclaimable reversals such as blocked credits under Section 17(5) and reversals under Rules 38, 42 and 43;
- Table 4(B)(2) is meant for temporary and reclaimable reversals; and
- The Electronic Credit Reversal and Reclaimed Statement (ECRRS) tracks only those reversals reported in Table 4(B)(2).
The publication further explains the procedural treatment for inadvertent reporting errors and methods for correcting reclaim ledger imbalances in subsequent returns.
Guidance on Reverse Charge Mechanism (RCM)
The FAQ guide provides practical clarification regarding:
- RCM liability on import of services;
- Reporting of RCM ITC under correct tables in GSTR-3B;
- RCM transactions involving unregistered persons;
- Self-invoicing requirements under Section 31(3)(f); and
- Proper disclosure of RCM liabilities in Table 3.1(d) and corresponding ITC claims in Table 4(A)(2)/(3).
ICAI clarified that mere procedural misclassification of eligible ITC between different reporting tables would not result in denial of ITC where tax has been duly paid and substantive conditions are satisfied.
Important Clarification on Rule 86B Compliance
The publication also addresses practical issues relating to non-compliance with Rule 86B of the CGST Rules, 2017, where taxpayers inadvertently discharge more than 99% of output tax liability through ITC instead of the mandatory 1% cash payment.
ICAI clarified that such excess utilisation of ITC does not invalidate the ITC itself but results in procedural non-compliance requiring corrective payment through Form DRC-03.
Guidance on IMS and GSTR-2B Issues
The publication contains detailed clarification regarding:
- Treatment of credit notes under Invoice Management System (IMS);
- Prevention of double ITC reversal;
- Handling deemed accepted credit notes;
- Non-reflection of Bills of Entry in GSTR-2B; and
- Correct use of IMS declaration facilities to avoid system validation errors.
ICAI clarified that eligible ITC on import of goods can still be claimed based on Bill of Entry and proof of tax payment even if the same is not reflected in FORM GSTR-2B due to ICEGATE transmission delays.
Clarifications on GSTR-1A and Negative Liability Adjustment
The FAQ guide also provides practical guidance regarding:
- Use of FORM GSTR-1A for missed invoices before filing GSTR-3B;
- Adjustment of negative liability statements generated due to excess credit notes; and
- Editability of interest and late fee auto-populated in Table 5.1 of GSTR-3B.
Useful Resource for Taxpayers and Professionals
ICAI stated that the publication has been prepared to assist taxpayers and professionals in navigating practical return filing challenges under GST and ensuring accurate compliance with evolving GSTN system validations and procedural requirements.
The publication is expected to serve as a valuable reference resource for Chartered Accountants, GST practitioners, businesses, and tax compliance teams dealing with GSTR-3B reporting and reconciliations.
