Retrospective Price Escalation Attracts Interest From Original Clearance Date: GSTAT Bengaluru

Gopinath TM Vs Mukand Limited (GSTAT Bengaluru)

Summary: The Goods and Services Tax Appellate Tribunal, State Bench Bengaluru, partly allowed the Revenue’s appeal in Gopinath TM v. Mukand Limited and restored interest of ₹13,85,623 under Section 50 of the CGST Act, 2017, while confirming the first appellate authority’s decision to quash the Section 122 penalty. The dispute concerned ₹54,44,190 in differential tax voluntarily paid following retrospective upward price revisions for goods cleared during April–June 2017. Mukand issued debit notes and supplementary invoices on 29 September 2018 and 15 October 2018 under Section 142(2)(a). The order addresses whether that transitional mechanism created a fresh tax-liability date or preserved interest referable to the original clearances.

The Assistant Commissioner, Hosapete Division, passed Order-in-Original No. BEL/GST/000/DIVH/ASC/VM/05/2021-22 dated 28 March 2022, appropriating the differential tax and demanding interest and penalty. The Additional Commissioner (Appeals), Belagavi, granted relief through Order-in-Appeal No. BGM-JJ-ADC-38-2023-24-GST dated 30 June 2023. The demand summary accompanying the Tribunal’s order records disputed penalty of ₹5,44,419, comprising ₹2,72,209.50 each under central and State tax; the determined penalty is nil. Interest of ₹13,85,623 comprises ₹6,92,811.50 under each component.

The Revenue argued that retrospective price escalation related back to the original clearances. In its submission, Section 39(7) governed payment of tax already due, Section 34(4) merely permitted reporting debit notes in the return for the month of issuance, and neither provision displaced the time of supply under Section 12. It also referred to the Law Committee’s observations during the 38th GST Council Meeting concerning interest when tax liability on debit notes is discharged. The Revenue challenged the dropping of penalty under Section 122(2)(a) as well.

Mukand maintained that it had declared the debit notes in GSTR-1 and discharged the tax through GSTR-3B for September and October 2018, thereby complying with Sections 39(7) and 34(4). It argued that Section 12 did not govern pre-GST removals and that Section 142(2)(a), which treats the supplementary invoice or debit note as relating to a deemed outward supply under GST and requires issuance within thirty days of price revision, provided the relevant compliance framework. It also submitted that the Department had rejected its request for provisional assessment under the earlier regime, requiring normal self-assessment, and sought to distinguish Steel Authority of India on that basis. Its submissions on penalty referred briefly to H.M.M. Ltd., Godrej Soaps and Essar Oil.

The Tribunal applied the Supreme Court’s larger-bench decision in Steel Authority of India Ltd. v. Commissioner of Central Excise, reported in 2019 (366) ELT 769 (SC), which reaffirmed SKF India and International Auto. Referring particularly to paragraph 63, it reasoned that a retrospectively revised price became the true value of the goods at original removal. In the Tribunal’s interpretation, Section 142(2)(a) provided a procedural bridge for reporting the differential transaction and paying tax after the GST transition; it did not create a fresh charging event or erase the historical interest liability. It similarly treated Sections 39(7) and 34(4) as reporting and payment machinery that did not postpone accrual. The rejection of provisional assessment did not alter its conclusion because it considered the price-escalation principle independent of that administrative classification.

On penalty, however, the Tribunal found that the differential liability resulted from a contractual escalation clause and a bona fide interpretation of complex transitional provisions. It recorded no suppression, fraud, wilful misstatement, tax evasion or contumacious conduct, and noted voluntary discharge of the differential tax upon price finalisation. It therefore restored the original interest demand but upheld the quashing of penalty. The Revenue succeeded only to the extent of interest; the matter was not remanded.

Cases Discussed

• Steel Authority of India Ltd. v. Commissioner of Central Excise, Raipur, 2019 (366) ELT 769 (SC), Civil Appeal No. 2150 of 2012 — Supreme Court. The Tribunal relied particularly on paragraph 63 for the effect of retrospective price escalation on the value at original removal and applied that reasoning to the transitional GST dispute.
• Commissioner of Central Excise v. International Auto Ltd., 2010 (250) ELT 3 (SC) — Supreme Court. Cited as a decision reaffirmed in Steel Authority of India concerning interest on differential duty arising from price revision.
• Commissioner of Central Excise, Pune v. SKF India Ltd., (2009) 13 SCC 461; 2009 (239) ELT 385 (SC) — Supreme Court. Cited as an earlier decision reaffirmed by the larger bench in support of interest on differential duty.
• Collector of Central Excise v. H.M.M. Limited, 1995 (76) ELT 497 (SC) — Supreme Court. Cited by the respondent in support of its submission that penalty could not survive if the underlying demand failed. The Tribunal ultimately sustained interest but retained penalty relief on the bona fide nature of the transitional dispute.

1. Introduction: The Constitutional and Statutory Architecture of Transitional Tax Liability

“Taxes are the price we pay for a civilized society, and the rule of law demands that fiscal statutes be interpreted not through the myopic prism of artificial legal fictions, but through the enduring reality of economic transactions and statutory intent.”

This appeal concerns the legal transition from the erstwhile indirect tax regime to the Goods and Services Tax (GST) introduced on July 1, 2017. The central question is whether a retrospective upward price revision under a pre-existing contract, treated as a “deemed outward supply” via Section 142(2)(a) of the Central Goods and Services Tax Act, 2017, extinguishes historical interest liability on delayed tax payments, or whether the underlying economic reality requires the enhanced value to relate back to the original date of clearance.

The Respondent, M/s. Mukand Limited, cleared goods between April 2017 and June 2017, subsequently raising debit notes on September 29, 2018, and October 15, 2018, to discharge differential tax of Rs. 54,44,190/-. While the original adjudicating authority (OIO) correctly enforced statutory interest under Section 50, the First Appellate Authority (OIA) set aside the demand by misinterpreting the transitional provisions.

Applying the binding precedent of the Hon’ble Supreme Court in Steel Authority of India Ltd. v. Commissioner of Central Excise, alongside CCE v. SKF India Ltd. and International Auto Ltd., this order evaluates the statutory matrix, restores the enforceability of interest, and addresses the issue of penalty.

1. Chronology of Events (from OIO to OIA)

III. Grounds of Appeal of the Appellant (Revenue) Against the OIA

The Appellant (Revenue) challenges the Order-in-Appeal (OIA) on the following core grounds:

• Error in Setting Aside OIO: The OIA erred in setting aside the Order-in-Original (OIO) by holding that interest under Section 50 of the CGST Act, 2017 ( the Act) is not recoverable on differential tax paid via supplementary invoices.
• Flawed Interpretation of Section 39(7): The ADC (Appeals) erroneously held that the due date for discharging GST on supplementary invoices is the 20th of the month following their issuance, rather than relating back to the month of the original invoices. Section 39(7) of the Act simply mandates paying tax due; whether tax is “due” depends on the Time of Supply (Section 12 of the Act ), not the date a debit note is raised.
• Legislative Intent and Section 34(4): While Section 34(4) allows details of a debit note to be declared in the return of the month of its issuance, it is purely reporting machinery. As noted by the Law Committee during the 38th GST Council Meeting, ITC on debit notes is linked to the condition that interest is paid when tax liability is discharged.
• Erroneous Dropping of Penalty: The ADC (Appeals) dropped penalties under Section 122(2)(a) of the Act solely because no tax was deemed due from the taxpayer, which is legally flawed since tax was due from the date of actual supplies.

IV. Respondent’s Defense Anchored on Section 142(2)(a) of the CGST Act, 2017

In defense of the OIA, the Respondent counter-argues as follows:

• Compliance with Sections 39(7) and 34(4): Declaring debit notes in GSTR-1 and paying GST in GSTR-3B for the month of issuance (Sept/Oct 2018) constitutes timely payment under Section 39(7).
• Inapplicability of Section 12: Section 12 applies only to supplies made under the GST Act. For pre-GST removals, Section 142(2)(a) treats supplementary invoices as “deemed outward supplies made under this Act,” prescribing to a 30-day window from price revision. Compliance with this framework eliminates any delay or Section 50 interest.
• Rejection of Provisional Assessment / Steel Authority Relevance: The Department rejected their pre-GST request for provisional assessment, forcing clearances under normal self-assessment. Hence, the Respondent claims Steel Authority of India Ltd. (which dealt with provisional assessment finalization) does not apply to post-GST debit notes under Section 34(4).
• Immunity from Penalty: Relying on case law (CCE v. H.M.M. Ltd., Godrej Soaps, Essar Oil, etc.), the Respondent argues that if the primary demand (interest) fails, penalties under Section 122 must automatically collapse.

V. Our Analysis and Findings

1. Examination of Appellant Grounds, Respondent’s Counter, and Case Law via the ApexCourt’s Ration in Steel Authority of India

A rigorous and logical synthesis of the rival submissions reveals the legal fallacy in the Respondent’s defense when measured against the binding ratio of the Larger Bench of Hon’ble Supreme Court in Steel Authority of India Ltd. v. Commissioner of Central Excise [ (2019) 366 ELT 769 (SC)] ( Steel Authority Case ) which upheld Apex Court’s Division Bench judgments in CCE & v. SKF India Ltd.(2009) 13 SCC 461 ; 2009 (239) ELT 385 (SC) and CCE v. International Auto Ltd. (2010) 2 SCC 67; 2010 (250) ELT 3 (SC)

2. The Core Mandate of Steel Authority Ratio (Para 63 of Steel Authority case):

The Supreme Court explicitly held in Paragraph 63 of Steel Authority Case that when a price escalation has retrospective operation, the later-discovered or finalized price becomes the true value of the goods even at the time of original removal. The Court observed that interpreting statutory rules to mean that duty/tax “ought to have been paid” only when prices are finalized or supplementary invoices are raised does “violence to the provisions of the Act.”

3. Harmonizing Section 142(2)(a) of CGST Act 2017 with the Supreme Court’s Ration in Steel Authority Case:

Taxpayers frequently misinterpret Section 142(2)(a)—which mandates that a supplementary invoice or debit note be “deemed to have been issued in respect of an outward supply made under this Act”—as creating a fresh charging event or shifting the liability date to the post-GST era. However, harmonizing this provision with the binding ratio of Steel Authority of India, the deeming fiction under Section 142(2)(a) serves a purely procedural and administrative purpose. It provides the statutory gateway and mechanism for a registered taxpayer to report the differential transaction, issue a GST-compliant debit note, and discharge tax through the electronic portal. It does not rewrite economic history or alter the original time when the value accrued.

4. Inescapable Incidence of Interest:

Therefore, while Section 142(2)(a) bridges the procedural transition by allowing the payment of differential tax of Rs. 54,44,190/- via debit notes issued on September 29, 2018 and October 15, 2018, carries forward the historical liability for interest. Because the differential tax relates back to the original clearance period, the mandatory interest under Section 50 attaches automatically.

5. Dismantling the Respondent’s Section 39(7) and Section 34(4) Fallacy:

Respondent’s Claim: The due date shifts to the 20th of the month following the issuance of the debit note.

Our Finding: Just as Rule 8 of Central Excise could not shift the accrual date, Section 39(7) and Section 34(4) are purely procedural and administrative reporting mechanisms for the electronic portal. They provide the gateway to report transactions and file GSTR-3B, but they do not rewrite economic history or alter the original time when the value accrued.

6. Untenable Section 12 / Section 142(2)(a) “Fresh Tax Point” Theory:

Respondent’s Claim: Section 142(2)(a) creates a “deemed outward supply under this Act,” making the liability born fresh on the date of the supplementary invoice.

Our Finding: The deeming fiction in Section 142(2)(a) is merely a transitional bridge allowing taxpayers to issue debit notes and discharge tax post-July 1, 2017. It is not a legal time-machinethat erases the time-value of money enjoyed by the assessee during the interim legacy-to-GST period. The enhanced value relates back to the original clearance period.

7. Neutralizing the “Denied Provisional Assessment” Distinction

Respondent’s Claim: Steel Authority only applies to formal provisional assessments under the old regime; since their request was denied, the ratio is inapplicable to post-GST debit notes.

Our Finding: This is a distinction without a difference. The Supreme Court’s ratio is grounded in the universal economic reality of price variation clauses, not the administrative label of “provisional assessment.” Whether a price is subject to a contractual escalation clause or formal provisional assessment, an upward price revision is retrospective, and the tax was legally due from inception.

8. Penalty under Section 122: and Bonafide Transition

While the principal tax appropriation and the accompanying statutory interest are fully sustainable under the law, the imposition of penalty under Section 122 of the CGST Act, 2017 requires careful judicial scrutiny:

Nature of the Default: The differential tax liability did not arise from any suppression of facts, fraud, willful misstatement, or evasion of tax. Rather, it arose purely out of a contractual price escalation clause occurring during a complex legislative transition from the Central Excise regime to the GST regime.

Bonafide Interpretation of Transitional Law: The applicability of Section 142(2)(a) and the legal effect of supplementary invoices on pre-existing contracts involved intricate questions of statutory interpretation. The Respondent acted under a bonafide belief regarding the transitional mechanism.

Inapplicability of Penalty: Penalties under fiscal statutes are designed to punish deliberate infractions or contumacious conduct. In the absence of suppression or deliberate noncompliance —and given that the differential tax was voluntarily discharged upon finalization of prices—the imposition of penalty under Section 122 is unwarranted and legally unjustified. Accordingly, the quashing of penalty in OIA is legally sustainable.

VII. Conclusions

• Setting Aside the OIA: The findings and conclusions in the Order-in-Appeal (OIA ) which set aside the Order-in-Original (OIO) regarding the non-sustainability of interest are hereby found to be legally flawed and are liable to be set aside.
• Restoration of Interest Demand: In light of the grounds raised by the Appellant against the OIA, the comprehensive rebuttal of the Respondent’s counters, and the binding ratio of the Hon’ble Supreme Court in Steel Authority of India Ltd. (2019) (specifically paragraph 63, reaffirming SKF India Ltd. and International Auto Ltd. ), the demand for interest amounting to Rs. 13,85,623/- under Section 50 of the CGST Act, 2017 as originally determined in the OIO, is restored and upheld as valid, mandatory, and fully enforceable.
• Setting Aside of Penalty: The penalty imposed upon the Respondent under Section 122 of the CGST Act, 2017 is liable to be set aside in view of the bonafide nature of the transitional dispute and the absence of any contumacious conduct or suppression.

Accordingly, we pass the following order:

ORDER

1. The order in OIA with respect to non-sustainability of demand of interest is set side.

2. Demand for interest amounting to Rs. 13,85,623/- under Section 50 of the CGST Act, 2017, as originally determined in OIO is upheld.

3. The ruling in OIA with regard to quashing of the penalty imposed under Sec 122 of the Act is upheld.

4. The appeal filed by the Appellant (Revenue) against the OIA is accordingly partly allowed to the extent of upholding the interest demand, while confirming the relief granted regarding the penalty.
