Introduction
The Goods and Services Tax framework divides a single tax into three heads: Central Tax (CGST), State Tax (SGST) and Integrated Tax (IGST). Each head is accounted for separately and Section 49 of the Central Goods and Services Tax Act, 2017 (the “CGST Act”) prescribes how input tax credit (ITC) may move between them. In practice, however, taxpayers who correct earlier errors in their returns frequently find that an excess under one head cannot be absorbed in the same head, and the return format offers no way of carrying it forward.
In Nagamangalamurthy Ganesh Kumar v. M.G. Automobiles Sales & Service (APL/43/BUR/2026), reported as (2026) 47 Centax 249 (Tri. – GST – Bengaluru), the Goods and Services Tax Appellate Tribunal (“GSTAT”), Division Bench, Bengaluru, dealt with this question. The Hon’ble Bench held that a registered person’s direct adjustment of excess IGST against CGST and SGST liability, made in the course of a bona fide correction in the first year of GST, was a procedural infraction that caused no loss of revenue and could not sustain a demand for tax, interest and penalty.
The Tribunal also made an independent finding of wider significance during 2017-18, there was no statutory obligation on the recipient of a credit note to reverse ITC, since that obligation was introduced only with effect from 01.10.2025.
Background of the Case
The Respondent, M.G. Automobiles Sales & Service, is a partnership firm based in Ballari, Karnataka, dealing in motor vehicles and parts. Between September and November 2017, it received supplier credit notes and instead of reversing the attributable ITC, paid an equivalent amount as output tax of Rs. 3,53,544 each under CGST and SGST and Rs. 22,30,083 under IGST, largely through its electronic credit ledger.
In December 2017 it reversed the credit and reduced that month’s liability by the earlier payments. The CGST and SGST excess was absorbed within the same heads, but December’s IGST liability was only Rs. 4,436 and GSTR-3B could not carry the negative balance forward. The Respondent therefore applied the excess IGST against its CGST and SGST liability, at Rs. 11,15,064 each and reported net figures.
Following an audit, a show cause notice issued in 2022 proposed recovery of Rs. 22,30,083 as IGST short paid, with interest and penalty. On 30.06.2023 the Assistant Commissioner, Ballari Division, instead confirmed Rs. 22,30,128 as CGST and SGST short paid, relying on Circular No. 26/26/2017-GST. The Additional Commissioner, Belagavi, set that order aside on 30 September 2024, and the Department appealed to the GSTAT.
Contentions of the Parties
The core dispute was narrow. There was no quarrel over the reversal of ITC in December 2017, nor over the existence of the excess paid under each head, nor over the set-off of excess CGST and SGST within their own heads. The disagreement concerned only the IGST excess and the route by which it was applied. The Tribunal framed the following questions:
- Whether the Respondent was right in utilizing the excess IGST of an earlier tax period against its CGST and SGST liability for December 2017, through a net-basis adjustment in GSTR-3B?
- Whether the premise of the show cause notice, namely that the Respondent ought to have reversed ITC on supplier credit notes during 2017-18, had any statutory basis?
- Whether, in the absence of any loss of revenue, a demand for tax, interest and penalty could be sustained on account of the adjustment?
A subsidiary irregularity was also noted. The adjudication order confirmed the demand under a different head from that proposed in the notice and in an amount Rs. 45 more than the amount proposed in the notice. Since the Respondent had not raised this at any stage, the Tribunal treated it as an oversight in the early days of GST and condoned it.
The Statutory Framework
The Tribunal examined the following provisions of the CGST Act, the CGST Rules, 2017 and departmental guidance, which formed the statutory backdrop to the dispute.
- Section 34 governs credit and debit notes. As it stood in 2017-18, it permitted the supplier to reduce its output tax liability on issuing a credit note, subject only to the incidence of tax not having been passed on. It imposed no corresponding obligation on the recipient.
- Section 43(1) contemplated matching of a supplier’s credit notes against a corresponding reduction in the recipient’s ITC claim. It depended on Forms GSTR-2 and GSTR-3, which were suspended after the 23rd GST Council meeting in November 2017, and the section was omitted by the Finance Act, 2022 with effect from 1 October 2022.
- The substituted first proviso to Section 34, effective from 1 October 2025 and operationalized through Notification No. 16/2025-Central Tax dated 17 September 2025, for the first time conditions the supplier’s reduction on the recipient’s reversal of attributable ITC.
- Rule 37 requires reversal of ITC where the recipient fails to pay the supplier within 180 days. It addresses non-payment of consideration and is distinct from credit notes.
- Section 39 provides for furnishing of returns, with sub-section (9) permitting rectification of errors within the prescribed time.
- Section 49(4) and (5) govern utilization of the electronic credit ledger. IGST credit must first be applied against IGST, and the balance may then be applied against CGST and SGST, in that order.
- Section 54 and Rule 92(1A) govern refunds. Where tax was originally paid by debit to the electronic credit ledger, the refund is not paid in cash but re-credited to the ledger as ITC through Form GST PMT-03.
- Para 4 of CBIC Circular No. 26/26/2017-GST clarifies that since GSTR-3B cannot report differential figures for past months, corrections are to be reported on a net basis in the current return, without negative entries, with any unabsorbed amount carried to subsequent returns or claimed as a refund.
The Tribunal’s Reasoning
The premise of the notice had no legal support. The show cause notice proceeded on the basis that the Respondent ought to have reversed ITC on the credit notes received, rather than paying tax as output. The Tribunal found that during July 2017 to March 2018 there was no provision in the Act or Rules directing a recipient to reduce ITC on account of a supplier’s credit note. Section 34 reduced only the supplier’s liability, Section 43 matching was never operational and Rule 37 dealt with a different situation altogether. The recipient-side obligation arose only from 01.10.2025.
The Tribunal observed that GSTR-3B is a summary return, and that Circular No. 26/26/2017-GST required differential figures for past months to be worked out outside the form and reported net in the current period. The backend working for December 2017, which the Department did not dispute, showed that the Respondent had done exactly this. Since GSTR-3B permitted no negative entries and no carry-forward of the IGST balance, the Respondent was left either to claim a refund or to track the excess outside the return.
The Tribunal traced what would have followed had the Respondent sought a refund under Section 54. Because the excess IGST had been discharged from the electronic credit ledger, Rule 92(1A) would have restored it to that ledger as IGST credit through Form PMT-03. Once re-credited, Section 49(5) would have permitted its use against CGST and SGST. The direct set-off therefore produced the same outcome by a shorter route. The only lapse was that the refund and re-credit procedure had not been followed, and this came after two bona fide corrections by the Respondent.
The Tribunal held that the initial payment of tax and the subsequent reversal of ITC demonstrated the Respondent’s bona fides and that the adjustment caused no revenue loss. It relied on Orient Traders v. Deputy CCTes (Audit)-3, 4, DGSTO-3, (2023) 3 Centax 63 (Kar.), where the Karnataka High Court held that bona fide and inadvertent errors in the first year of GST deserve a lenient view. It further noted that the electronic, return-based architecture of GST was new to taxpayers of varied expertise and resources, and that inadvertent errors were to be expected.
The wrong-head payment cases were distinguished. The Tribunal found that Saji S., Ocean E Mart and Ayiswarya Polymers concerned tax deposited under the wrong head by mistake, whereas the present case involved the utilization of excess IGST against CGST and SGST. Those decisions therefore had no direct application. It accepted, however, the principle drawn from Saji S. v. Commissioner of State Tax, that an assessee should not suffer for technical misclassification where there is no loss of revenue.
The Order
The Department’s appeal was dismissed, and the Tribunal passed the following order.
- No interference was called for in the order of the First Appellate Authority, to the extent that it set aside the adjudication order.
- The demand of tax, interest and penalty confirmed by the Assistant Commissioner of Central Tax, Ballari Division, by order dated 30.06.2023 for the period July 2017 to March 2018, was set aside.
- There was no order as to costs.
An Important Caveat in the Judgment
The Tribunal did not declare a general right to adjust excess output tax under one head against liability under another. It expressly described the Respondent’s adjustment as procedurally wrong, and it set aside the demand because the infraction followed bona fide corrections, caused no loss of revenue, occurred in the first year of GST and would have reached the same result through the refund and re-credit route. The ruling denies the Department the ability to raise a demand on a purely procedural lapse of this kind. It does not dispense with the prescribed procedure.
The reasoning also rests on a specific factual foundation. The equivalence between the direct set-off and the refund route holds because the excess IGST had been paid from the electronic credit ledger, so that a refund would have returned as credit. Where excess tax has been paid in cash, Rule 92(1A) provides for a cash refund, and the same logic would not straightforwardly apply. Taxpayers should therefore be cautious in treating this decision as authority for cross-head adjustments in later periods or on different facts.
Why This Matters and Key Principles by the Tribunal
- Demands for earlier periods premised on a recipient’s failure to reverse ITC against a supplier’s credit note lack statutory support, No recipient-side reversal on credit notes before 01.10.2025.
- Where the refund route would have restored the same credit for the same use, a direct set-off is a procedural lapse, not a short payment attracting tax, interest and penalty.
- Net-basis corrections under Circular No. 26/26/2017-GST are legitimate. The Circular does not, on its terms, confine such adjustments to the same tax head.
- Following Orient Traders, inadvertent errors in the first year of GST causing no revenue loss should not attract punitive consequences. Bona fide first-year errors warrant a lenient view.
- A demand confirmed under a different head or in a higher amount than proposed remains open to challenge where the point is raised in time.
- Taxpayers facing 2017-18 demands should check whether payments came from the credit ledger, whether revenue was actually lost, and whether the notice identifies the correct head and amount. Compliance review for open matters.
AMLEGALS REMARKS
The GSTAT’s decision affirms that a taxpayer who has paid the correct tax through the credit ledger should not pay it twice merely because an adjustment followed an unprescribed route. By tracing the refund and re-credit mechanism under Section 54, Rule 92(1A) and Section 49(5), the Tribunal showed that the demand would only have duplicated tax already paid. The decision is nonetheless balanced: it does not endorse cross-head adjustment as of right, and confines relief to bona fide, revenue-neutral corrections in the first year of GST. Its finding on recipients’ credit note obligations before 01.10.2025 is likely to carry wider influence.
As an early reasoned GSTAT decision, the ruling will be persuasive before lower authorities, though open to challenge before the High Court under Section 117. Taxpayers should document corrections carefully and follow the refund and re-credit procedure where an excess cannot be absorbed in the same head. For the Department, demands should rest on a clear statutory basis and a real loss of revenue, not procedural form alone.
