Anti-Profiteering Authority and Enforcement under GST

Updated 11 October 2026 · Fact-checked

Section 171 of the CGST Act requires a supplier to pass on any GST rate cut or input tax credit benefit to the buyer through a commensurate price reduction. A designated Authority examines whether this happened. If it finds profiteering, a penalty of 10% of the profiteered amount applies unless that amount is deposited within thirty days of the order.

Understand Anti-Profiteering Authority and Enforcement

GST is meant to lower the tax burden on consumers. Two things can lower a supplier's cost or tax: a cut in the GST rate, and the benefit of input tax credit. Anti-profiteering is the rule that the supplier must not keep that gain. Section 171(1) says any reduction in rate of tax, or the benefit of input tax credit, shall be passed on to the recipient by way of commensurate reduction in prices.

Section 171(2) lets the Central Government, on the Council's recommendation, constitute an Authority, or empower an existing one, to examine whether the ITC availed or the rate cut has actually produced a commensurate price reduction. The amount not passed on is the profiteered amount. It is defined in Explanation 1 to section 171, which follows section 171(3A).

Section 171(3) says the Authority exercises such powers and discharges such functions as may be prescribed. The detailed complaint procedure, the bodies that screen or investigate a complaint, and the directions the Authority can give are not set out in the section. Check the current CGST Rules for them before you describe them in an answer.

The Authority is whichever body the Government notifies or empowers under section 171(2). Check the current notification before you name it. Section 171, Explanation 2 (inserted w.e.f. 1-11-2024) says the expression "Authority" includes the Appellate Tribunal. The proviso to section 171(2) also lets the Government, on the Council's recommendation, notify a date after which the Authority will not accept any request for examination. Always check the latest notification for that date.

The Act itself provides one consequence of profiteering: under section 171(3A), the supplier is liable to a penalty of ten per cent of the profiteered amount, unless that amount is deposited within thirty days of the date of passing of the order. Any other direction, such as a price reduction or return of the amount to recipients, is not listed in section 171. If you mention such directions, attribute them to the CGST Rules and check the current text.

Key rules to remember

Duty to pass on benefit: Rate-cut or ITC benefit → commensurate reduction in price (s.171(1)); Covers both a reduction in tax rate and the benefit of input tax credit, on goods or services or both.
Profiteered amount: Profiteered amount = Price actually charged − Price that reflects the commensurate reduction; Explanation 1 to s.171 (after s.171(3A)): the amount determined on account of not passing on the benefit to the recipient.
Penalty: Penalty = 10% × profiteered amount (s.171(3A)); Levied only after the Authority's examination concludes the person has profiteered.
Penalty waiver: No penalty if profiteered amount is deposited within 30 days of the date of the Authority's order; The 30 days run from the date of passing of the order, not from receipt.
Powers of Authority: Powers and functions as may be prescribed (s.171(3)); The powers of the anti-profiteering Authority come from s.171(3) and the rules made under it. Section 105 (civil court powers) names the Authority, Appellate Authority and National Appellate Authority in the advance-ruling provisions, so do not cite it as the source of the anti-profiteering Authority's powers.
Appellate Tribunal procedure: Not bound by the Code of Civil Procedure, 1908; guided by natural justice; can regulate its own procedure (s.111(1)); It has civil court powers for matters listed in s.111(2) and can enforce orders as a decree (s.111(3)). Explanation 2 to s.171 includes the Appellate Tribunal in 'Authority'.

How to solve Anti-Profiteering Authority and Enforcement questions

Use this order for any case-based question on anti-profiteering. It follows the exam pattern: provision, facts, conclusion.

1Identify the trigger: a reduction in the rate of tax, or a new or higher input tax credit benefit. If neither exists, profiteering does not arise.
2State the rule: section 171(1) requires the benefit to be passed on by a commensurate price reduction to the recipient.
3Compare the facts: price before, price after, and the tax or credit change. Work out what the price should have been.
4Compute the profiteered amount as the difference, multiplied by the quantity or number of recipients.
5Name the forum: the Authority notified or empowered under s.171(2) examines the matter (check the current notification; the Appellate Tribunal is included under Explanation 2). Say that its powers and functions are as prescribed under s.171(3), and check the current CGST Rules for the procedure.
6State the consequence given in the Act: the penalty of 10% of the profiteered amount under s.171(3A). If you mention other directions such as price reduction or return of the amount, attribute them to the CGST Rules and not to section 171.
7Apply the 30-day proviso: no penalty if the profiteered amount is deposited within thirty days of the date of passing of the order.
8Close with a one-line conclusion that names the amount, the penalty and whether it is avoidable.

Quickest way: Four-line anti-profiteering answer

When to use it: Use when the question is short, or when you have under ten minutes for a part of a larger question.

Write: Section 171(1) requires any rate cut or ITC benefit to be passed on by commensurate price reduction.
Compute the profiteered amount in one line: (price charged − correct price) × units.
Write the penalty: 10% of the profiteered amount, nil if deposited within 30 days of the order.
Add one line on forum: the Authority notified or empowered under s.171(2), with powers and functions as prescribed under s.171(3).

Common mistakes in Anti-Profiteering Authority and Enforcement

Applying the 30-day relief from the date the order is received or from the date of complaint.
Students remember '30 days' but not the starting point.
Fix: The proviso to s.171(3A) counts thirty days from the date of passing of the order by the Authority.
Calculating penalty at 10% of the price or of the tax rather than of the profiteered amount.
The base is skipped when working under time pressure.
Fix: First compute the profiteered amount, then take 10% of that figure only.
Saying anti-profiteering applies only to rate cuts.
Most news examples involve rate reductions.
Fix: Section 171(1) covers both a reduction in rate and the benefit of input tax credit.
Citing section 105 as the source of the anti-profiteering Authority's powers.
Section 105 uses the words 'Authority' and 'National Appellate Authority', which look similar to the anti-profiteering Authority.
Fix: Section 105 gives civil court powers to the Authority, Appellate Authority and National Appellate Authority named in it, which are the advance-ruling bodies (see also s.101A). For anti-profiteering, say that the Authority's powers and functions are as prescribed under s.171(3).
Naming a body as the Authority without checking the current notification.
Older notes describe a body that was constituted earlier, and the position can change by notification.
Fix: Write that the Authority is the body constituted or empowered by the Government under s.171(2), and check the current notification. Add that Explanation 2 includes the Appellate Tribunal.
Stating the complaint procedure and remedies as if they were in section 171.
Students mix up the Act with the Rules and memorised notes.
Fix: Section 171 gives the duty, the Authority, the prescribed powers and the penalty. Describe procedure and any other directions as coming from the CGST Rules, and check the current text.

Worked examples

Example 1

Sharma Appliances Ltd sold a product at a base price of ₹10,000 plus GST at 28%. The GST rate on the product was cut to 18%, but the company continued to charge ₹12,800 per unit and sold 500 units after the cut. The Authority finds profiteering. Compute the profiteered amount and the penalty if the amount is not deposited within thirty days of the order.

Show the solution

Trigger: reduction in the rate of tax from 28% to 18%. Section 171(1) requires a commensurate price reduction.
Price before the cut: ₹10,000 + 28% of ₹10,000 = ₹10,000 + ₹2,800 = ₹12,800.
Commensurate price after the cut with the base price unchanged: ₹10,000 + 18% of ₹10,000 = ₹10,000 + ₹1,800 = ₹11,800.
Profiteered per unit: ₹12,800 − ₹11,800 = ₹1,000.
Total profiteered amount: ₹1,000 × 500 = ₹5,00,000.
Penalty under s.171(3A): 10% of ₹5,00,000 = ₹50,000, because the amount was not deposited within thirty days of the order.

Answer: The profiteered amount is ₹5,00,000 and the penalty is ₹50,000. Had the company deposited ₹5,00,000 within thirty days of the order, no penalty would apply.

Example 2

Residents of a housing project complain that the builder, Kavya Constructions Pvt Ltd, got a higher input tax credit benefit but did not reduce flat prices. Explain how the matter is examined under section 171 and what the outcome can be.

Show the solution

Provision: section 171(1) requires the benefit of input tax credit to be passed on to the recipient by commensurate price reduction.
Forum: the Authority notified or empowered by the Government under s.171(2) examines whether the ITC availed has resulted in a commensurate reduction in the price of the flats. Check the current notification for the body. Under Explanation 2, 'Authority' includes the Appellate Tribunal.
Powers and procedure: under s.171(3) the Authority exercises the powers and functions as prescribed. Check the current CGST Rules for how a complaint reaches the Authority and how it is investigated. Also check whether the Government has notified a cut-off date for accepting requests for examination under the proviso to s.171(2).
Conclusion on profiteering: if the Authority finds that the builder did not pass on the ITC benefit, the amount not passed on is the profiteered amount under Explanation 1.
Outcome under the Act: s.171(3A) makes the builder liable to a penalty of 10% of the profiteered amount, unless the amount is deposited within thirty days of the date of passing of the order.
Other directions: section 171 does not list directions such as price reduction or return of the amount to the buyers. If you mention them, attribute them to the CGST Rules and confirm the current text.

Answer: The Authority notified under s.171(2) examines whether the builder passed on the ITC benefit. If it concludes that the builder has profiteered, the builder is liable to a penalty of 10% of the profiteered amount, unless it deposits that amount within thirty days of the date of the order. The detailed procedure and any further directions are matters for the CGST Rules, to be checked in their current form.

Exam tips

Quote section 171(1), 171(2), 171(3) and 171(3A) by number. These are the sections you can safely cite; for rule-based procedure, describe the steps without rule numbers and say the Rules should be checked.
Always show the profiteered amount calculation before the penalty. Marks are given for the working.
Describe the Authority as the body notified or empowered under section 171(2), and check the current notification. Mention that the Appellate Tribunal is included in 'Authority' under Explanation 2.
Include the 30-day proviso in every penalty answer. It is the most frequently tested detail.
In open-book papers, keep section 171 and the current CGST Rules on anti-profiteering bookmarked, but write the answer in the provision, facts, conclusion format.

Anti-Profiteering Authority and Enforcement: frequently asked questions

What is anti-profiteering under section 171 of the CGST Act?

It is the rule that any reduction in the rate of tax, or the benefit of input tax credit, must be passed on to the recipient by a commensurate reduction in prices. An Authority examines whether this has happened. If the supplier has profiteered, section 171(3A) makes it liable to a penalty of ten per cent of the profiteered amount.

Who examines an anti-profiteering complaint?

Section 171(2) lets the Government constitute an Authority, or empower an existing one, to examine whether the rate cut or ITC benefit resulted in a commensurate price reduction. Under section 171(3) it exercises the powers and functions as prescribed. The steps by which a complaint reaches the Authority are in the CGST Rules, so check their current text.

Which body is the Authority at present?

The Act does not name a body. Section 171(2) only lets the Government constitute or empower an Authority, so check the current notification before you name it. Explanation 2 to section 171 says 'Authority' includes the Appellate Tribunal, and the Government can specify a date after which requests for examination are not accepted.

What is the penalty for profiteering and can it be avoided?

The penalty is ten per cent of the profiteered amount under section 171(3A). It is not leviable if the profiteered amount is deposited within thirty days of the date of the Authority's order.

What powers does the Authority have during examination?

Section 171(3) says the Authority exercises such powers and discharges such functions as may be prescribed, so look at the CGST Rules for the detail. Section 105 gives civil court powers to the Authority, Appellate Authority and National Appellate Authority named in it, which belong to the advance-ruling provisions. Do not cite it as the source of the anti-profiteering Authority's powers.
