41. Anti-Profiteering (Section 171) and Rate-Cut Pricing

Section 171(1) requires that any reduction in the rate of tax on a supply, or any benefit of input tax credit, be passed on to the recipient by a commensurate reduction in prices. The provision was meant for the transition in 2017, when many businesses gained new credits, and for later rate cuts. It does not fix prices; it forbids keeping a tax benefit that the law intended for the buyer.

41.1 The Machinery and Its Sunset

Period	Authority examining complaints
2017 to 30 November 2022	National Anti-profiteering Authority (NAA)
1 December 2022 to 30 September 2024	Competition Commission of India
From 1 October 2024	Principal Bench of the GSTAT (pending and new cases)
On or after 1 April 2025	No new request for examination accepted (sunset notified on 30 September 2024)

Cases filed before the sunset continue before the GSTAT. Where profiteering is established, the person must reduce prices and return the profiteered amount with interest, or deposit it in the Consumer Welfare Funds where the recipients cannot be identified. Under section 171(3A), a penalty of 10% of the profiteered amount applies unless the amount is deposited within 30 days of the order.

Judicial view: Validity of anti-profiteering

Reckitt Benckiser India (P) Ltd. v. Union of India (Delhi High Court, 2024): The Court upheld the constitutional validity of section 171 and the related rules. It held that the absence of a fixed methodology did not make the provision arbitrary, because the method must suit the facts of each case. Individual orders could still be challenged on their facts, and some cases were sent back for that purpose.

Practical point: pending cases are argued on facts, such as product-wise computation, cost increases absorbed, and whether the benefit reached the customer in another form.

41.2 Why It Still Matters after GST 2.0

The rate cuts of 22 September 2025 were the largest since 2017. Many goods moved from 12% or 18% to 5%, and from 28% to 18%. Because of the sunset, no new anti-profiteering complaint can be filed for these cuts. But the Government publicly expected the benefit to be passed on, monitored prices of common items and took consumer grievances through its consumer helpline channels. Large brands, retailers and e-commerce platforms were also watched by the media and by customers comparing old and new prices. For a business, the risk now is reputational and commercial rather than a statutory order, but the numbers should still be defensible.

Illustration 197: Revising prices after GST 2.0

Mehta Distributors revised the price list on 22 September 2025, keeping the pre-tax price unchanged.

Item	Old MRP (Rs.)	Pre-tax price (Rs.)	New MRP (Rs.)
Toothpaste: 18% to 5%	118	118 / 1.18 = 100	100 x 1.05 = 105
Butter: 12% to 5%	560	560 / 1.12 = 500	500 x 1.05 = 525
Air conditioner: 28% to 18%	44,800	44,800 / 1.28 = 35,000	35,000 x 1.18 = 41,300

If a business also absorbs a genuine cost increase, it should keep a note of the increase (raw material prices, wages) with dates, so that the reduction it did pass on can be explained.

41.3 Stock in Hand and Credit

A rate cut does not require reversal of ITC on stock in hand, because the goods remain taxable. The credit simply exceeds the output tax for a while. Where goods become fully exempt, such as UHT milk, paneer and Indian breads, ITC on inputs held in stock and in semi-finished or finished goods must be reversed under section 17(2) and rules 42 and 43, or under section 18(4) where all supplies become exempt.

Illustration 198: Credit on stock bought before the cut

Arora Electronics bought air conditioners in August 2025 at Rs. 30,000 each plus 28% GST of Rs. 8,400. After 22 September 2025 it sells them at Rs. 35,000 plus 18% GST of Rs. 6,300.

Step 1: Output tax Rs. 6,300; ITC Rs. 8,400. Excess credit Rs. 2,100 per unit stays in the electronic credit ledger and is used against other output tax.

Step 2: Inverted duty refund under section 54(3) is not available for this excess. CBIC clarified in 2020 that where the input and output are the same goods, credit accumulated because of a rate reduction does not qualify.

41.4 Practical Steps after a Rate Cut

Rate masters: update HSN-wise rates in the ERP and billing software from the effective date; test a sample of invoices.
Price communication: issue revised price lists to distributors and retailers with the effective date; keep copies.
MRP on packs: the Legal Metrology guidelines of 9 September 2025, relaxed on 18 September 2025, allowed manufacturers, packers and importers to show the revised MRP on unsold stock by sticker, stamping or online printing up to 31 December 2025, keeping the original MRP visible. The newspaper advertisement requirement was replaced by circulars to dealers with a copy to the Legal Metrology authorities. Check any later extension before relying on it.
Contracts: long-term supply contracts with tax clauses should be read; a price stated as "inclusive of taxes" may need renegotiation to pass on the cut.
Evidence file: keep the old and new price lists, cost data and dealer circulars together for at least the record retention period.

Chapter summary

• Section 171 requires rate cuts and ITC benefits to be passed on through commensurate price reductions.

• Complaints moved from the NAA to the CCI on 1 December 2022 and to the GSTAT Principal Bench from 1 October 2024; no new request is accepted from 1 April 2025.

• The Delhi High Court upheld the provision in Reckitt Benckiser (2024), leaving methodology to the facts of each case.

• For GST 2.0 there is no statutory complaint route, but commercial and reputational scrutiny continues; keep price workings on file.

• Rate cuts do not require ITC reversal on stock unless goods become exempt; accumulated credit from a rate cut on the same goods is not refundable.

• Revised MRP stickering on old stock was permitted up to 31 December 2025 with the original MRP visible.

PART I: ACCOUNTING, RECONCILIATION AND PRACTICE

GST in the books, reconciliations, year-end closing and notice management

This Part turns from the law to the working desk. It shows how GST is recorded and disclosed, how returns are reconciled with the books month by month and at year-end, and how a practice handles notices and litigation in an orderly way.
