Reverse Charge Mechanism; Anti-Profiteering Authority — Law of Taxation Notes

Reverse Charge Mechanism; Anti-Profiteering Authority

Normally the seller collects GST and pays it. But when you hire an advocate, or buy from an unregistered farmer, the law flips it — you, the recipient, pay the tax directly to the government. That flip is the reverse charge, and alongside it the anti-profiteering authority makes sure that when GST rates fall, businesses actually pass the saving to you.

A. Reverse Charge Mechanism (RCM)

The normal (“forward”) charge puts the duty to collect and pay GST on the supplier. Reverse charge (s.9(3)/(4) CGST, s.5 IGST) shifts that duty to the recipient — the buyer pays the GST directly to the government instead of paying it to the supplier.

When RCM applies:

Notified goods/services (s.9(3)) — the Government notifies specific supplies where the recipient pays: e.g. advocate/legal services to a business, goods transport agency services, services of a director to a company, import of services, cashew/tobacco leaves from agriculturists.
Supplies from unregistered persons (s.9(4)) — in notified cases, a registered recipient buying from an unregistered supplier pays GST under reverse charge.

Why it exists: to collect tax where the supplier is unorganised, unregistered, or hard to tax (small service providers, farmers), and on imports — shifting the compliance to the (usually registered) recipient. The recipient who pays under RCM can normally claim it back as input tax credit.

B. Anti-Profiteering Authority

The problem it solves. When the GST Council cuts a rate or a business gets extra input tax credit, the business should reduce its price. But it might quietly pocket the benefit. Section 171 CGST requires that any reduction in the tax rate, or benefit of input tax credit, be passed on to the recipient by a commensurate reduction in prices.

The authority. To enforce this, the National Anti-Profiteering Authority (NAA) was set up (its functions were later transferred to the Competition Commission of India). It can investigate complaints, and order the business to reduce prices, refund the excess to consumers (with interest), impose penalty, and even cancel registration in serious cases.

🧩 WORKED EXAMPLE — Reverse charge on advocate’s services

Facts. ‘X’, a senior advocate, provides legal services to a company; GST is payable on the fee.

Rule. Legal services by an advocate to a business entity are notified under s.9(3) for reverse charge — the recipient company, not the advocate, pays the GST.

Apply. The advocate does not charge or collect GST; the company self-assesses the GST on the fee and pays it directly to the government.

Conclusion. GST is paid by the company under reverse charge, which can then take input tax credit of it — a classic RCM example the exam repeats.

In Simple Terms: Reverse charge flips the normal rule — instead of the seller collecting GST, the buyer pays it directly (used for advocates, transporters, imports, and unregistered suppliers). The anti-profiteering rule (s.171) forces businesses to pass on GST rate cuts and credit benefits to customers as lower prices, enforced by a dedicated authority.

Case Laws

Union of India v Mohit Minerals (P) Ltd. (2022) — upheld reverse charge on ocean freight but read down the levy on the importer where IGST was already borne, clarifying RCM’s limits.
