Anti-Profiteering under Section 171: What the GST Tribunal Has Decided

The window for new anti-profiteering complaints closed on 1 April 2025. The liability did not.

Section 171 of the CGST Act has no limitation period of its own, no monetary threshold and no sunset for matters already in the system. What it now has, after the Finance (No. 2) Act, 2024, is a cut-off date for fresh applications and a new adjudicator. Complaints made before 1 April 2025 are being decided today by the Principal Bench of the Goods and Services Tax Appellate Tribunal, and the orders coming out of it are the first reasoned anti-profiteering rulings from a judicial forum rather than an administrative authority.

Seven of them are now reported. They decide, among other things, when a construction project is "complete", why a developer fights to have its buyers declared untraceable, and why the answer to that question is worth more than the profiteered amount itself. This note sets out the provision, the machinery and the ratios.

Where the law now stands

Section 171(1) states the obligation in a single sentence:

Any reduction in rate of tax on any supply of goods or services or the benefit of input tax credit shall be passed on to the recipient by way of commensurate reduction in prices.

Two triggers, therefore: a rate reduction, or additional input tax credit. One remedy: a commensurate reduction in price. Nothing in the sub-section requires a complaint, a threshold or a time limit.

Section 171(2) empowers the Central Government, on the Council's recommendations, to constitute or empower an Authority to examine whether the benefit has in fact been passed on. Section 148 of the Finance (No. 2) Act, 2024 added a proviso allowing the Government to notify a date from which the Authority "shall not accept any request for examination", with Explanation 1 defining that expression as a written application by an applicant, and Explanation 2 providing that "Authority" includes the Appellate Tribunal.

Section 171(3A), inserted by section 112 of the Finance (No. 2) Act, 2019 and brought into force on 1 January 2020 by Notification 1/2020-Central Tax, imposes a penalty equal to ten per cent of the profiteered amount, with a proviso that no penalty is leviable if the amount is deposited within thirty days of the order.

The practical effect of the 2024 proviso is set out in Tata Play, where the Delhi High Court recorded that Notification 19/2024-Central Tax dated 30 September 2024 fixed 1 April 2025 as the cut-off, so that "it is only complaints prior to 01st April, 2025 that can be considered by the Principal Bench of the GST Appellate Tribunal".

That is a closing door, not a closed one. A supply made in 2017 can still be the subject of an order in 2026, provided the application reached the system in time — as the dates in the table below show.

Three custodians in seven years

The handovers are not merely administrative history. Every one of the seven Tribunal decisions reviewed here began as an investigation before the National Anti-profiteering Authority, passed to the Competition Commission, and was then remanded to the Director General of Anti-Profiteering for fresh computation before reaching the Tribunal. In Merit Magnum Construction the first investigation report was dated 31 August 2021 and the final supplementary report 30 June 2026 — a little under five years in transit.

The jurisdiction is also exclusive. Section 109(1) extends the Tribunal's remit to "conducting an examination or adjudicating the cases referred to in sub-section (2) of section 171", and the second proviso to section 109(5) provides that such matters "shall be examined or adjudicated only by the Principal Bench". No State Bench may hear them.

This has a consequence for the remedy that is easy to miss. Section 117(1) gives an appeal to the High Court only against orders of the State Benches. Section 118(1)(a) gives an appeal to the Supreme Court from any order passed by the Principal Bench. Since anti-profiteering is heard only by the Principal Bench, the statutory appeal from such an order lies to the Supreme Court and not to the High Court.

The statutory clock, and why it does not stop anything

Every one of those periods has been held directory. In A.J. Enterprises the respondent argued that the Authority was bound to pass its order within six months and that the proceedings were therefore barred. The Tribunal rejected it, holding that "the time limit of six months prescribed under Rule 133 of CGST Rules are directory in nature" and relying on the Supreme Court in P. T. Rajan, on the Delhi High Court in Nestle India, and on paragraph 158 of Reckitt Benckiser, where the Court held that the Rules "do not provide any consequence in case the time limits provided there under lapse" and that beneficial legislation must receive a construction favouring the consumer. EMAAR reached the same conclusion on rules 129 and 133 together.

A respondent who has waited nine years for an order should not expect the delay to be a defence.

Reckitt Benckiser: the methodology, and what survived it

The governing judgment is the Delhi High Court's decision of 29 January 2024 in the batch led by W.P.(C) 7743/2019, Reckitt Benckiser India Pvt. Ltd. v. Union of India, reported at (2024) 14 Centax 374 (Delhi). It did two things that pull in opposite directions, and both matter.

First, it upheld the constitutional validity of section 171 and of rules 122, 124, 126, 127, 129, 133 and 134, holding at paragraph 102 that "whatever is saved in tax must be reduced in price" and that section 171 "incorporates the principle of unjust enrichment". It added the warning, at paragraph 163, that where power has been exercised arbitrarily the remedy "is to set aside such orders on merits" — "[w]hat will be struck down in such cases will not be the provision itself which invests such power on the concerned authority but the erroneous application of the power."

Second, it rejected the methodology then in use for real estate. At paragraph 124 the Court held that "no fixed/uniform method or mathematical formula can be laid down", there being "no one size that fits all". At paragraph 129 it held the existing approach flawed because it compared the ratio of input tax credit to turnover, when in real estate "there is no direct correlation between the turnover and the Input Tax Credit availed for a particular period". The Court directed instead:

one needs to calculate the total savings on account of introduction of Goods and Services and Tax for each project and then divide the same by total area to arrive at the per square feet benefit to be passed on to each flat buyer. This would ensure that flat-buyers with equal square feet area received equal benefit.

That rejection is why every case in this group was remanded and recomputed. The scale of the correction is visible in Alton Buildtech, where the National Anti-profiteering Authority had determined Rs 6,24,48,008 by order dated 16 October 2020; on re-investigation the ratio moved from 13.80 per cent pre-GST to 14.72 per cent post-GST, an incremental benefit of 0.92 per cent, and the amount became Rs 44,18,355 plus GST of Rs 3,53,468 — Rs 47,71,823 in all. The respondent accepted the revised report. A reduction of roughly ninety-two per cent is a reason to read the remand order before paying anything.

The replacement methodology has now been tested

The obvious objection to the post-remand exercise is that the Director General simply wrote "purchase value" where it had written "turnover". That objection was argued and rejected in LICHFL Care Homes, decided by the Delhi High Court on 28 September 2026 — the first High Court decision reviewing a Tribunal anti-profiteering order.

The Court held that paragraph 129 "did not hold that every comparison between the pre-GST and post-GST period was impermissible", and that the distinction was "significant":

The purchase value has not been used as a proxy for turnover for the purpose of determining a benefit relatable to the amounts realised from individual buyers. It has been used as the denominator for quantifying the proportion of ITC available against the project expenditure during the relevant period.

Because the saving was then converted into a project-wide per square foot figure and applied to each buyer's area, the final step was "directly aligned" with paragraph 129. The Court also rejected the argument that notionally available but unclaimed pre-GST CENVAT credit should be built into the comparison: the ST-3 returns showed nil credit actually availed, and "the authorities were justified in examining the actual ITC availed during the respective periods rather than introducing a hypothetical credit".

Two points of practice follow. The first is the test the Court applied: "The question is not whether the methodology is the only possible methodology, but whether it is a fair and reasonable methodology consistent with the specific direction issued by this Court." The second is the forum. The Court was careful that the proceedings were "not an appeal against the quantum determined by GSTAT", and that Articles 226 and 227 are "not intended to substitute the Court's own assessment of factual material for that of the specialised adjudicatory authority". A respondent who takes a quantum dispute to the writ court should expect that limitation on review; the statutory appeal, as noted above, runs to the Supreme Court.

The four scenarios

Paragraph 128 of Reckitt Benckiser settles the position for four fact patterns, and the Tribunal has applied them as a grid.

Scenario (c) is the one respondents most often resist, because it requires a benefit to be paid to a buyer who paid in full before GST existed. In Merit Magnum Construction the developer argued that twenty-four buyers had paid in full pre-GST and six had made only nominal post-GST payments, so paragraph 128(a) applied. The Tribunal held the case fell within scenario (c): the project had commenced pre-GST, credit was availed post-GST, and the purchasers "became entitled to the benefit of additional Input Tax Credit accruing to the Respondent in the post-GST period".

Scenario (d) is where a respondent can win outright. In Sobha Limited the villa was applied for on 17 June 2019, the buyer's agreement was executed on 8 July 2019, and the whole of the construction and payment followed. The Director General found the credit-to-purchase-value ratio had fallen, from 12.26 per cent to 11.02 per cent — a difference of minus 1.24 per cent. The Tribunal held the case covered by paragraph 128(d), the price having been "determined after factoring the benefit of ITC, which became available to the Respondent in the post-GST regime", and went further: the complainants "have no locus standi and legal rights to contest the DGAP report". A declining ratio is a complete answer.

When does a project end?

Merit Magnum Construction is the clearest authority on the investigation window, and it is worth following the reasoning because it is structural rather than factual.

The developer had applied for the Occupancy Certificate on 25 April 2017 — before GST — and argued the project was therefore complete pre-GST. The certificate was actually granted on 13 October 2017. The Tribunal held:

It is well settled that a project is deemed to be completed only upon the actual grant of the Occupancy Certificate from the Competent Authority, and not upon the mere filing of an application therefor.

The developer's own conduct confirmed it: credit of Rs 2,91,894 was availed between 1 July and 13 October 2017.

The window then closes at that date, and the reason is the credit chain rather than the certificate. Paragraph 5 of Schedule III treats the sale of a building as neither a supply of goods nor of services, subject to paragraph 5(b) of Schedule II, which makes construction for sale a supply of service except where the entire consideration is received after the completion certificate or first occupation. Read with sections 17(2) and 17(3), a unit sold after the certificate is an exempt supply and the credit attributable to it is not available at all. Hence:

no question of profiteering can arise in respect of units sold after the issuance of the Occupancy Certificate, as no admissible input tax credit benefit survives in relation to such units.

The Director General's original period of 1 July 2017 to 31 March 2019 was accordingly cut back to 1 July to 13 October 2017. On the shorter window the ratio rose from 3.90 per cent to 22.16 per cent, an increase of 18.26 per cent; total savings were Rs 2,40,548 over 89,434 square feet, or Rs 2.69 per square foot; applied to 88,660 square feet sold, the profiteered amount was Rs 2,38,495, and with GST at twelve per cent, Rs 2,67,114.

Note what the correction did and did not do. Shortening the period raised the percentage sharply but cut the absolute amount from Rs 11,20,094 to Rs 2,67,114, because the purchase value in the denominator fell further than the ratio rose. The ratio is not the liability.

The question worth more than the tax: who is identifiable

Rule 133(3) gives the adjudicator a menu. Two clauses matter:

• Clause (b) — return to the recipient the amount not passed on, "along with interest at the rate of eighteen per cent. from the date of collection of the higher amount till the date of the return of such amount".
• Clause (c) — where "the eligible person does not claim return of the amount or is not identifiable", deposit fifty per cent in the Central Consumer Welfare Fund and fifty per cent in that of the concerned State.

Sub-rule (3) in this form was substituted by Notification 26/2018-Central Tax dated 13 June 2018. The words adding interest to the clause (c) deposit were inserted later, by rule 17(c) of the Central Goods and Services Tax (Fourth Amendment) Rules, 2019, notified as Notification 31/2019-Central Tax dated 28 June 2019.

That difference in dates is the whole game, and it explains an apparent conflict in the Tribunal's orders.

In Mallikarjuna Cinema Hall the President held that the clause (c) interest provision is prospective, not clarificatory or curative, applying the Constitution Bench in Vatika Township and laying emphasis on the word "further" in the amending notification. The investigation ran from 1 January to 30 June 2019, so only three days fell within the amended provision. Interest was allowed on Rs 27,350 — the profiteered amount of Rs 16,50,166 divided by 181 days and multiplied by three — with the principal deposited half in the Central and half in the Telangana Consumer Welfare Fund. In A.J. Enterprises the violation ran from 15 November 2017 to 30 September 2019 and interest was confined to 28 June 2019 onwards, the amount going half to the Central and half to the Maharashtra Fund.

Clause (b) carries no such limitation, because the interest in it was never inserted in 2019. In Vasavi and GP Infra the Tribunal held the provision "mandatory in nature" and that it "leaves no discretion in its application", interest being "compensatory in nature and intended to ensure restitution of the time value of money that rightfully belongs to the recipients". EMAAR awarded it for a period running from 1 July 2017 to 16 July 2019. Merit Magnum Construction awarded it on a period lying entirely in 2017.

So a respondent found to have profiteered in 2017 pays interest from 2017 if its buyers can be named, and from June 2019 if they cannot. On a seven-year-old liability that difference can exceed the profiteered amount. The Tribunal has noticed:

This Tribunal is of the view that the Respondent's reliance on Rule 133(3)(c) is clearly an attempt to avoid paying interest on the profiteered amount.

And it has closed the route. In Merit Magnum Construction the developer pleaded that some buyers had never complained, some were untraceable and some had resold their flats, and offered to deposit into the Consumer Welfare Fund under protest. The Tribunal held clause (c) to be "a residuary provision ... attracted only in those cases where the eligible recipients are genuinely unidentified", creating a legal fiction for the case where consumers cannot be found, and to be construed strictly:

The expression "recipient is not identifiable" occurring in Rule 133(3)(c) cannot be interpreted to mean that the recipient has not filed a complaint, is not presently available, or that the computation has not initially been made buyer-wise. The test under Rule 133(3)(c) is one of objective impossibility of identification.

Books of account, allotment letters, agreements for sale, demand notices and payment schedules all disclose identity. For a real estate developer the point is close to unarguable, and the Tribunal said so bluntly: the respondent had itself relied on buyer-specific data and categorised purchasers by the timing of payments, and "[s]uch a stand itself demolishes the contention that the recipients are unidentifiable". It added that no "genuine or demonstrable attempt" to trace the buyers had been made.

Clause (c) is therefore available to a cinema or a restaurant, which sells to walk-in consumers it cannot name, and effectively unavailable to a builder.

The remaining ratios

Penalty follows the calendar, not the finding. Section 171(3A) came into force on 1 January 2020 and has no retrospective operation. In Merit Magnum Construction, Alton Buildtech, A.J. Enterprises and EMAAR the investigation periods ended before that date and no penalty was imposed, the Tribunal holding that "penal provisions cannot be applied retrospectively unless expressly stated". In Vasavi and GP Infra the period of contravention ran from 1 July 2017 to 30 September 2024 and penalty was attracted, because part of it fell after commencement. Where a period straddles 1 January 2020, expect the penalty.

No set-off between buyers. This is the single most expensive rule for a large project. In EMAAR the Director General found a shortfall of Rs 55,85,980 across 226 homebuyers and an excess of Rs 69,38,986 across 204 others. The respondent had, on a net basis, over-passed the benefit. It made no difference:

The obligation under Section 171(1) of the CGST Act, 2017 is recipient-specific and each homebuyer is independently entitled to receive the commensurate benefit accruing on account of additional ITC. Any excess amount passed on to a particular recipient can be adjusted only with that recipient and cannot extinguish or reduce the Respondent's liability towards other recipients.

Vasavi and GP Infra holds the same. A developer who passed on generously to early buyers and meanly to later ones owes the later ones in full.

GST on the profiteered amount is part of the profiteered amount. The argument that the tax was deposited with the Government and cannot be refunded twice was rejected in Vasavi and GP Infra: the consideration collected from buyers was inclusive of tax, so the excess realisation "inherently includes the corresponding GST component", and the issue is "restitution of the entire excess realisation". This follows paragraph 157 of Reckitt Benckiser, that neither Government intended to collect additional tax on the inflated price. Twelve per cent was added in Merit Magnum Construction, Alton Buildtech, Vasavi and GP Infra and EMAAR.

Credit on input services counts. In Vasavi and GP Infra the respondent sought to exclude service-related credit from the comparison. The Tribunal held the contention "devoid of merit": the benefit "includes ITC on both goods and services, and cannot be restricted only to material inputs".

The investigation is not confined to the complainant. EMAAR held that once an investigation is validly initiated the Director General "is empowered to examine the position of all similarly situated recipients in the project", the statutory enquiry being directed at the supply rather than the individual complainant. This rests on paragraphs 159 to 161 of Reckitt Benckiser, where the Court read "any supply of goods or services" in rule 129(2) widely and drew on the Supreme Court's decision on analogous powers in Excel Crop Care. One complaint can open a whole project. In Tata Play a single complaint produced a finding of profiteering exceeding Rs 450 crore.

Records beat denials. In Vasavi and GP Infra thirteen customers sent emails denying that they had received any benefit. The Tribunal nonetheless allowed the respondent credit for Rs 46,40,136 on the strength of its books of account, customer ledgers and credit notes. Contemporaneous records cut both ways, and here they cut for the respondent.

A rate reduction creates a rebuttable presumption, and the rebuttal must be evidenced. A.J. Enterprises concerned a Subway franchisee. The rate on restaurant service fell from eighteen to five per cent with effect from 15 November 2017 by Notification 46/2017-Central Tax (Rate), and the franchisee raised the base prices of two items on that very date. It pleaded increases in royalty, advertisement contribution, lease rent and aggregator commission aggregating 12.69 per cent. The Tribunal held the presumption unrebutted for want of "cogent, clear and un-equivocal evidences", and drew the obvious inference from the timing: the increase on the very date the notification took effect indicated an intention "to maintain the same MRP that existed till 14.11.2017". Costing and pricing do respond to market forces — Mallikarjuna Cinema Hall accepts that expressly — but the exercise "should be a genuine exercise of rising of prices and not a mere pretence".

Price control by a State is not a defence. In Mallikarjuna Cinema Hall the theatre relied on the Telangana Cinemas Act, Government orders and High Court directions fixing maximum ticket prices. The Tribunal held that those instruments fix a ceiling only, and "the fixing of prices of a particular class, or any locality or particular show is the discretion of the theatre owners". The respondent had also admitted in its written submissions that it had attempted to recover some profit in a competitive market, which the Tribunal treated as "a clear admission".

Higher output tax does not answer a credit allegation — but it may still defeat it on facts. Tata Play is the caution against treating the two as the same question. The rate on direct-to-home services rose from fifteen to eighteen per cent in November 2017, and the company produced figures showing it had absorbed Rs 245 crore of additional tax while holding its pack prices constant. The Authority had nonetheless found profiteering of more than Rs 450 crore on inputs. The Delhi High Court set that order aside and remanded the matter to the Principal Bench to examine "whether there was any actual profiteering at all or whether the Investigation Report ... was based merely on conjecture or surmise". The allegation was not held untenable in principle; it was held to require a factual examination that had not been done.

What this means in practice

For a respondent with a live matter before the Principal Bench, the order of work is reasonably settled.

1. Check the period first. Establish the date of the completion or occupancy certificate from the competent authority, not the date of the application. Everything after it is outside the enquiry, because the credit is not admissible on exempt supplies.
2. Check which scenario applies. A project wholly within the GST regime falls under paragraph 128(d) and attracts nothing, as Sobha Limited shows. A declining credit-to-purchase-value ratio ends the matter.
3. Do not plead that your buyers cannot be found unless identification is objectively impossible. For anyone holding allotment letters and payment schedules the plea will fail, and it will have signalled that the real dispute is interest.
4. Reconstruct the computation rather than attacking the methodology as such. After LICHFL Care Homes, an attack on ITC-to-purchase-value as a disguised ITC-to-turnover comparison is unlikely to succeed. Disputes about the purchase value, the credit actually availed, the certified area and the sold area are where the amounts move — as the fall from Rs 6.24 crore to Rs 47.71 lakh in Alton Buildtech demonstrates.
5. Get the chartered accountant's certificate right. In Merit Magnum Construction the Tribunal directed the respondent to furnish certified purchase and credit data for the shortened window, and the final figure was built on it.
6. Count the thirty days. The proviso to section 171(3A) removes the ten per cent penalty altogether if the profiteered amount is deposited within thirty days of the order. Where the period straddles 1 January 2020 this is the cheapest decision available.
7. Do not rely on delay. The periods in rules 128, 129 and 133 are directory.
8. Plan the appeal for the right forum. Section 118(1)(a) routes an appeal against a Principal Bench order to the Supreme Court. Writ proceedings are available, but LICHFL Care Homes shows the review will be confined to jurisdictional error and will not revisit quantum.

A final observation on the corpus. The seven Principal Bench decisions reported so far are not the whole of the Tribunal's anti-profiteering work: its own orders refer to decisions in Pyramid Infratech, Urban Essence, Proctor & Gamble Group and Dange Enterprise, and the order under challenge in LICHFL Care Homes was a Tribunal order of 23 March 2026 that is not among them. The body of law is larger than the reported set and is growing month by month. Anyone advising on a pending matter should check for orders later than the ones discussed here.
