Quick Answer
Section 171 of the CGST Act, 2017 requires that any reduction in the GST rate or increase in Input Tax Credit be passed on to the buyer as a commensurate reduction in price. Keeping the price the same while paying less tax is "profiteering". Enforcement moved from NAPA (dissolved 1 Dec 2022) to the CCI, and now to the GSTAT Principal Bench — but no new complaints are accepted for supplies on or after 1 April 2025.

When it applies
What Triggers a GST Anti-Profiteering Complaint?
Section 171 is triggered in two situations — the benefit of a lower GST rate or extra input tax credit must reach the buyer.
| Trigger | What the supplier must do | Example |
|---|---|---|
| GST rate reduction | Cut the selling price so the buyer's final payable amount falls in line with the lower rate | A ₹100 item at 18% (₹118) whose rate drops to 5% must sell at ₹105 — not stay at ₹118 |
| Increase in ITC availability | Pass on the input-cost saving from newly available credit as a lower price | A sector that regains ITC entitlement must reflect the lower input cost in its prices |
| GST 2.0 rate cuts (22 Sep 2025) | Reduce MRP/price on goods moved from 12%/28% to 5%/18% under the two-slab reform | Note: fresh cases are no longer opened for supplies on/after 1 Apr 2025 |
The GST 2.0 rationalisation (effective 22 September 2025) replaced most 12%/28% slabs with a two-slab 5%/18% structure (plus a 40% demerit rate). Verify rates on the GST portal.
Section 171 is a legal duty, not a suggestion
Failing to pass on a rate cut or ITC benefit is profiteering. The profiteered amount plus 18% interest (from the date of supply to the date of return/deposit) is recovered and either refunded to identifiable buyers or paid into the Consumer Welfare Fund.

The Anti-Profiteering Complaint & Investigation Process
A complaint travels from a screening committee to the DGAP for investigation, and finally to the adjudicating authority for an order.

GSTATHears the supplier & passes order
| Stage | Authority | What happens |
|---|---|---|
| 1. Complaint filed | Standing Committee on Anti-Profiteering | Applicant submits old vs new price, GST rate before/after, and evidence the benefit was not passed on |
| 2. Referral | Standing Committee → State Screening Committee | Prima facie cases referred to the DGAP; weak ones closed |
| 3. Investigation | DGAP (Director General of Anti-Profiteering), CBIC | Examines invoices and GSTR data, computes the profiteered amount, issues a report |
| 4. Adjudication | GSTAT Principal Bench | Supplier is heard; order confirming or dropping profiteering is passed |
| 5. Execution | Jurisdictional GST Commissioner | Amount + 18% interest returned to buyers or deposited in the Consumer Welfare Fund |
Worked example
How the Profiteered Amount Is Calculated
The DGAP compares the pre-rate-cut base price with the post-rate-cut price actually charged. If a supplier keeps the buyer's total the same after the rate falls, the difference per unit is profiteering.
Correct — benefit passed on
Base price₹100
Old GST @ 18%₹18
New GST @ 5%₹5
Buyer now pays₹105
Profiteering — price held
Base price raised to₹112.38
New GST @ 5%₹5.62
Profiteered / unit₹7
Buyer still pays₹118
Multiply the per-unit profiteering by the total volume sold during the profiteering period to arrive at the amount recovered, plus 18% interest.
Consequences
Penalty for GST Profiteering
| Situation | Consequence |
|---|---|
| Benefit not passed on | Profiteered amount + 18% interest p.a. from date of supply to date of return/deposit |
| Buyers identifiable | Amount refunded directly to the affected buyers with interest |
| Buyers not identifiable | Amount deposited into the Consumer Welfare Fund |
| Non-compliance with the order | Recovered as arrears of tax by CGST officers |
| Extreme / repeat cases | Further penalty / cancellation of registration in aggravated cases |
Section 171 does not fix a separate percentage penalty; the core liability is the profiteered amount plus 18% interest.

Anti-Profiteering Compliance Checklist
Even though new complaints have sunset from 1 April 2025, suppliers should keep clean evidence that every past rate cut or ITC gain was passed on.
- Map every SKU affected by a GST rate change
- Recompute MRP/price on the effective date
- Document pre vs post-change base price
- Retain sales & pricing records for the period
- Reconcile with GSTR-1 outward supplies
- Reflect ITC-driven cost savings in pricing
- Keep board/pricing notes for defence
- Respond promptly to any DGAP notice
TaxClue Insight
The safest anti-profiteering defence is a documented, timely price cut on the exact effective date of every rate change. For pending DGAP or GSTAT matters, the computation methodology is where most disputes are won or lost — get the working reviewed before you respond.

Frequently Asked Questions
Basics
What is GST anti-profiteering?
GST anti-profiteering, under Section 171 of the CGST Act, 2017, is the legal requirement that any reduction in the GST rate or any increase in input tax credit availability be passed on to the buyer through a commensurate reduction in price. In short, if a supplier pays less GST after a rate cut, the customer must pay proportionately less — the supplier cannot keep the difference.
What is Section 171 of the CGST Act?
Section 171 is the anti-profiteering provision of the CGST Act, 2017. Section 171(1) requires benefits of rate reduction or extra ITC to be passed on by way of a commensurate price reduction. Section 171(2) empowers the Government to notify an authority to examine profiteering, and Section 171(3A) provides for penalty. The GSTAT Principal Bench is currently the notified authority.
What triggers anti-profiteering under GST?
Two things trigger Section 171: a reduction in the applicable GST rate on a supply, or an increase in the input tax credit available to the supplier. In either case, the cost benefit must be passed to the recipient as a lower price. If it is not, the retained benefit is treated as profiteering.
Does anti-profiteering apply if a business reduced prices voluntarily?
No. A supplier that proactively reduces prices in proportion to a GST rate cut — even before any complaint — is not liable under Section 171. Voluntary, timely compliance is exactly the intended outcome and provides full protection.
Authority & Sunset
Is NAPA still active in 2026?
No. The National Anti-Profiteering Authority (NAPA) was dissolved on 1 December 2022 following the 48th GST Council meeting. Its functions passed to the Competition Commission of India (CCI) on an interim basis, and the GSTAT Principal Bench was later notified as the anti-profiteering authority with effect from 1 October 2024. Section 171 itself remains part of the law.
Who handles GST anti-profiteering cases now?
The Principal Bench of the Goods and Services Tax Appellate Tribunal (GSTAT) in New Delhi is the notified anti-profiteering authority with effect from 1 October 2024, taking over from the CCI. The Director General of Anti-Profiteering (DGAP) still conducts the underlying investigation and submits its report to the GSTAT.
Has anti-profiteering been discontinued?
The mechanism has been given a sunset date. On the 53rd GST Council recommendation, no new anti-profiteering applications are accepted for supplies made on or after 1 April 2025. Section 171 has not been repealed and cases already in the pipeline continue before the GSTAT, but fresh complaints are no longer entertained after the sunset.
What happens to anti-profiteering cases pending from the NAPA period?
Cases pending when NAPA was dissolved moved first to the CCI and are now dealt with by the GSTAT Principal Bench. The sunset of 1 April 2025 stops new complaints; it does not close pending matters, which continue to be adjudicated under the existing Section 171 framework.
Process & Complaints
How does a consumer file a GST anti-profiteering complaint?
A buyer or business submits an application to the Standing Committee on Anti-Profiteering with the product/service details, the old price versus the new price, the GST rate before and after the change, and evidence that the benefit was not passed on. The Standing Committee (via the State Screening Committee for local matters) refers prima facie cases to the DGAP. Note that for supplies on or after 1 April 2025 new applications are no longer accepted.
How is the profiteered amount calculated?
The DGAP compares the pre-rate-cut base price with the price actually charged after the rate cut. In simple terms, if a ₹118 item (₹100 + 18% GST) should sell at ₹105 after the rate drops to 5% but is kept at ₹118, the ₹7 per unit retained is profiteering. This per-unit figure is multiplied by the volume sold in the profiteering period, and 18% interest is added from the date of supply to the date of return or deposit.
What is the role of the DGAP?
The Director General of Anti-Profiteering (DGAP) is the investigating arm under the CBIC. Once a case is referred, the DGAP examines invoices, price lists and GSTR data, computes the profiteered amount, and submits an investigation report to the adjudicating authority (now the GSTAT). The DGAP investigates but does not itself pass the final order.
Can a business be penalised if it reduced prices but not by the exact amount?
Yes. Section 171 requires a "commensurate" reduction. If a supplier passed on only part of the benefit, the shortfall is treated as profiteering and the supplier is liable for that amount plus 18% interest. Courts have, in some multi-product cases, accepted that exact computation is difficult and that reasonable methodologies may apply.
Penalty & Defence
What is the penalty for GST profiteering?
The core consequence is that the profiteered amount, plus 18% interest per annum from the date of supply to the date of return or deposit, is recovered. Where buyers are identifiable the amount is refunded to them; otherwise it goes to the Consumer Welfare Fund. Section 171(3A) also allows a penalty, and non-compliance with an order is recovered as arrears of tax.
Where is the profiteered amount deposited?
If the affected buyers can be identified, the profiteered amount with interest is returned to them directly. If they cannot be identified — common for low-value mass-market goods — the amount is deposited into the Consumer Welfare Fund, split between the central and state governments.
Can an anti-profiteering order be appealed?
Yes. An order passed by the anti-profiteering authority can be challenged before the High Court by way of a writ petition. Because computation methodology is often disputed, businesses typically contest both the finding of profiteering and the quantum determined by the DGAP.
How can a business protect itself from an anti-profiteering claim?
Cut prices on the exact effective date of every GST rate change, document the pre and post-change base price for each affected SKU, retain sales and pricing records for the period, and reflect any ITC-driven cost saving in pricing. Clean, contemporaneous records are the strongest defence if the DGAP ever examines your pricing.
