ICAI FAQs clarify GSTR-3B ITC reporting for import-service RCM

Import-service RCM credit and the Table 4(A) issue

FAQs attributed to the Institute of Chartered Accountants of India in the available source material address a practical GSTR-3B reporting problem: whether input tax credit relating to reverse-charge tax on an import of services must be denied merely because the taxpayer placed it in Table 4(A)(3). The clarification reported in the FAQs is that such placement does not by itself require denial, provided the credit is otherwise eligible.

That distinction is important. The question concerns classification within the ITC-available portion of a summary return, not an automatic determination that the underlying credit fails the substantive eligibility conditions. For taxpayers and reviewers, the first task is therefore to separate the return-entry error from the evidence supporting the tax payment and the ITC claim.

How GSTR-3B functions

The GST Portal guidance on Form GSTR-3B describes it as a simplified summary return through which taxpayers declare their GST liabilities for a tax period and discharge those liabilities. Every normal taxpayer and casual taxpayer is required to file it for each applicable tax period, including a nil period in which there was no business.

The official guidance states that monthly filers ordinarily file by the twentieth day of the month following the relevant tax period. For quarterly filers, the notified due date is ordinarily the twenty-second or twenty-fourth day of the month following the quarter, depending on the State or Union Territory. The Government may extend those dates by notification. These filing mechanics matter because Table 4 is part of the recurring return-control process through which a taxpayer records available, reversed and net ITC.

The return is not populated from one source alone. According to the portal, specified values flow from suppliers’ Form GSTR-1 or GSTR-1A filings and from the system-generated Form GSTR-2B, depending on the table concerned. Auto-population assists preparation, but the reported figure must still be checked against the taxpayer’s books, tax documents and the character of each inward supply.

What Table 4(A)(3) is designed to capture

Table 4(A) reports ITC available. The official table description for entry 4(A)(3) is “Inward supplies liable to reverse charge (other than 1 & 2 above).” The portal guidance explains that the entry is built from specified sections of GSTR-2B and is calculated on a net basis. It takes account of relevant invoices and debit notes, reduced by the identified reverse-charge credit notes and amendments.

The formula in the official guidance draws on Table 3, Part A, Section III of GSTR-2B and adjusts for reverse-charge credit notes and their amendments appearing in the stated parts of Tables 3 and 4. The resulting value can be positive or negative on a net basis. This is more specific than saying generally that “RCM credit goes in Table 4”: it identifies the data stream and the adjustments that feed the particular field.

The same guidance distinguishes neighbouring ITC entries. Table 4(A)(4) concerns inward supplies from an Input Service Distributor. Table 4(A)(5) concerns all other ITC on supplies from registered persons other than reverse charge. Each entry uses its own mapped GSTR-2B sections and adjustments. A classification review must therefore identify the transaction before choosing the sub-table.

Why import of services creates a reporting question

An import of services on which the recipient pays GST under reverse charge is not identical, for return-classification purposes, to every domestic inward supply liable to reverse charge. That is the setting in which the reported ICAI FAQ clarification becomes relevant. The taxpayer may have paid the reverse-charge liability and claimed credit but disclosed that credit in 4(A)(3), prompting a question over whether the selected row invalidates the claim.

The reported answer does not dispense with eligibility. It says that incorrect placement in 4(A)(3), standing alone, need not result in denial where the import-service RCM credit is otherwise admissible. The return entry remains capable of review or rectification; the point is that a disclosure mismatch should not automatically be treated as proof that no credit exists.

Auto-population does not replace reconciliation

GSTR-2B auto-population is a control input, not a substitute for classifying the transaction correctly. The GST Portal guidance notes that positive GSTR-2B values populate the relevant table, while a negative value may be represented as zero in specified circumstances; elsewhere the system works on a net basis. Credit notes and downward amendments can therefore affect the displayed amount.

For a professional review, the taxpayer’s working should reconcile the GSTR-3B claim with the reverse-charge liability, payment record, import-service documentation and the relevant GSTR-2B treatment. The review should identify the tax period, the amount originally entered, the table used, the table considered correct and the reason the credit remains eligible. That creates an audit trail without treating the portal-generated number as conclusive on entitlement.

Rectification and past-period review

Where a past return placed eligible import-service RCM credit in 4(A)(3), tax teams should first quantify the classification difference and determine whether any corrective disclosure is required under the applicable return mechanism. They should avoid a second claim that duplicates credit already taken. A rectification working should show that the exercise changes presentation rather than creates fresh entitlement.

The supporting file should retain the underlying tax-payment evidence, transaction records, return extracts and reconciliation. If the issue arises during scrutiny, the response can then explain the distinction between the substantive credit and the incorrect sub-table, while demonstrating that the same credit has not been availed twice.

Implications for taxpayers and advisers

The clarification is useful for return reviews because it discourages an outcome driven solely by the label of a Table 4(A) row. At the same time, it does not provide a safe harbour for unsupported ITC. Eligibility, payment under reverse charge, documentary support and reconciliation remain central.

CAs and GST teams should incorporate a specific import-service RCM check into monthly or quarterly close procedures. The check should compare the liability reported and discharged, the ITC claimed, the selected Table 4(A) entry and the GSTR-2B information available for the period. Exceptions can then be documented before filing rather than reconstructed after a notice.

Key takeaway

Eligible ITC on import-service reverse charge should not be denied only because it was placed in Table 4(A)(3) of GSTR-3B; professionals should nevertheless verify the underlying eligibility, reconcile the liability and credit, document the classification error and ensure that any rectification does not duplicate the claim.
