Reverse Charge Mechanism (RCM) in GST 2026: Complete India Guide

Most businesses understand that under GST, the supplier charges tax and deposits it with the government. But there is an important exception to this rule that catches many businesses off guard — the Reverse Charge Mechanism (RCM).

Under RCM, the responsibility to pay GST flips: it is the recipient — not the supplier — who must pay the tax directly to the government. Miss this, and you face tax demands, 18% interest per annum, and penalties that can equal 100% of the tax owed.

This 2026 guide covers everything: what RCM is, Section 9(3) and 9(4) triggers, the full list of notified goods and services, how to pay, self-invoice requirements, ITC eligibility, and practical worked examples for GTA transport, advocate fees, and purchases from unregistered vendors.

What is Reverse Charge Mechanism (RCM) in GST?

The Reverse Charge Mechanism is a provision under the GST law where the tax liability is shifted from the supplier to the recipient of goods or services. In the normal GST system (called forward charge), the supplier:

• Charges GST on the invoice
• Collects it from the buyer
• Deposits it with the government

Under RCM, the process is reversed:

• The supplier issues an invoice without charging GST (or issues a bill of supply)
• The recipient calculates the applicable GST themselves
• The recipient pays the GST directly to the government in cash
• The recipient issues a self-invoice for their own records

RCM vs. Normal GST (Forward Charge): Key Differences

Feature	Forward Charge (Normal GST)	Reverse Charge (RCM)
Who pays GST?	Supplier	Recipient
Who charges GST on invoice?	Supplier	No one — supplier issues invoice without GST
Who deposits tax with govt?	Supplier (via GSTR-3B)	Recipient (via GSTR-3B Table 3.1(d))
Invoice issued by whom?	Supplier	Recipient issues a self-invoice
Can ITC be used to pay the tax?	Yes	No — must pay in cash only
ITC claimable on tax paid?	Recipient can claim ITC	Recipient can claim ITC after paying in cash
Triggering provision	Normal supply rules	Section 9(3) or Section 9(4) of CGST Act

Section 9(3) — Mandatory RCM on Specified Goods and Services

Section 9(3) of the CGST Act (and corresponding IGST Act provisions) lists specific categories of goods and services where RCM always applies — regardless of whether the supplier is registered or not. The government has issued notifications specifying these categories.

Here is the complete table of notified categories as applicable in 2026:

Section 9(4) — RCM on Purchases from Unregistered Dealers

Section 9(4) of the CGST Act originally required every registered person to pay GST under RCM whenever they purchased goods or services from an unregistered supplier. This was a wide-ranging obligation that created massive compliance burdens for businesses of all sizes.

The Suspension in 2017 and Current Status

The original Section 9(4) was suspended by the government in October 2017 due to the compliance burden it created. It was later omitted and replaced with a more targeted version. As of 2026, the position is as follows:

When Does Section 9(4) Still Apply?

Scenario	RCM Under Section 9(4)?
A registered company buys stationery from an unregistered local shop	No — not applicable in 2026 for routine purchases
A registered person purchases goods/services in a notified category from unregistered supplier	Yes — if specifically notified
Composition scheme dealer purchasing from unregistered supplier	Yes — Section 10(4) applies; composition dealers must pay RCM on all inward supplies from unregistered persons
Renting of residential property from unregistered landlord to a registered business	Yes — covered under Section 9(3) notification, not 9(4)

Who Pays GST Under RCM: The Recipient, Not the Supplier

This is the most fundamental point about RCM and the one most frequently misunderstood. Under RCM:

• The supplier does not charge GST on the invoice
• The supplier does not collect GST from the buyer
• The supplier does not deposit GST with the government
• The recipient (buyer) is solely responsible for paying GST on the transaction
• The recipient pays this GST directly to the government — not to the supplier

How to Pay RCM GST: Cash Only — ITC Cannot Be Used

One of the most critical and frequently violated rules under RCM is this: RCM liability must be paid in cash only. You cannot use your Input Tax Credit (ITC) balance in the Electronic Credit Ledger to pay RCM.

Step-by-Step: How to Pay RCM GST

1. Identify all transactions attracting RCM during the tax period (month).
2. Calculate the GST amount for each RCM transaction at the applicable rate.
3. Ensure your Electronic Cash Ledger has sufficient balance (recharge via challan if needed).
4. File GSTR-3B and report RCM outward liability in Table 3.1(d) — "Inward supplies liable to reverse charge."
5. The system debits your Electronic Cash Ledger for the RCM amount.
6. After the RCM is paid in cash, you may claim ITC on the RCM paid in the same GSTR-3B (in Table 4A(3) — "Inward supplies liable to reverse charge").

Can You Claim ITC on RCM Paid? Yes — With Conditions

After paying RCM in cash, the recipient is eligible to claim Input Tax Credit (ITC) on the GST paid, subject to the following conditions:

• The goods or services received are used in the course or furtherance of business
• The recipient is a registered taxable person
• The supply is not blocked under Section 17(5) of the CGST Act
• The RCM GST has been actually paid in cash
• A self-invoice has been issued by the recipient
• The ITC is claimed within the time limits prescribed under Section 16(4)

When Is ITC on RCM Blocked?

Transaction	ITC on RCM	Reason
GTA transport for business goods delivery	Eligible (if 12% rate chosen)	Business use — ITC allowed at 12% rate
GTA transport at 5% rate	Not eligible	GTA opted for 5% without ITC benefit
Advocate fees for business legal work	Eligible	Business use — ITC allowed
Residential rent (used as employee personal accommodation)	Blocked	Section 17(5)(g) — personal consumption
Residential rent (used as business guest house)	Eligible (disputed — consult CA)	Business use, not personal residence
Security services for office	Eligible	Business use — ITC allowed
Director's fees (sitting fees, commission)	Eligible	Business use — ITC allowed
Sponsorship of a personal event (not business)	Blocked	Not in course of business

Self-Invoice Requirement Under RCM

When a registered recipient purchases goods or services from an unregistered supplier and RCM applies, the recipient must issue a self-invoice (also called an inward supply invoice). This is a legal requirement under Rule 36(1)(b) of the CGST Rules, 2017.

What is a Self-Invoice?

A self-invoice is a document prepared by the recipient on their own behalf to record the inward supply attracting RCM. It is not an invoice from the supplier — it is the buyer acting as the invoice-issuing party for their own purchase.

Practical Examples of RCM in Action

RCM and E-Commerce Operators: Section 9(5)

Section 9(5) of the CGST Act is a related but distinct provision from Sections 9(3) and 9(4). Under Section 9(5), the e-commerce operator (not the individual service supplier) is deemed to be the supplier and is liable to collect and pay GST on certain services supplied through their platform.

Key categories covered under Section 9(5) in 2026:

Service Category	E-Commerce Platform Examples	Who Pays GST?	Rate
Passenger transport services (cab aggregation)	Ola, Uber, Rapido	E-commerce operator	5%
Accommodation / hotel services (below ₹7,500/night)	OYO, MakeMyTrip, Goibibo	E-commerce operator	12%
Housekeeping services (plumbers, electricians, etc.)	Urban Company, UrbanClap	E-commerce operator	18%
Restaurant services (through food aggregators)	Swiggy, Zomato	E-commerce operator	5%

Frequently Asked Questions on RCM in GST

What is Reverse Charge Mechanism (RCM) in GST?

Under RCM, the liability to pay GST shifts from the supplier to the recipient. The buyer pays GST directly to the government instead of to the supplier. It applies to specified goods and services under Section 9(3) and, in limited cases, purchases from unregistered dealers under Section 9(4) of the CGST Act.

Can ITC be used to pay RCM liability?

No. This is an absolute restriction. RCM liability must always be paid from the Electronic Cash Ledger — i.e., in cash. You cannot use your ITC balance in the Electronic Credit Ledger to pay RCM. However, once you pay RCM in cash, you can claim ITC on that amount in the same return period (if the supply is eligible for ITC).

Who is liable to pay GST under RCM?

The recipient of goods or services is liable. The supplier receives payment from the buyer without GST, issues a regular invoice or bill of supply, and has no obligation to pay or remit any GST for that transaction. The entire GST responsibility rests with the registered recipient.

Is GTA service covered under RCM?

Yes — Goods Transport Agency (GTA) services fall under Section 9(3) mandatory RCM. When a registered recipient uses a GTA that has not opted for forward charge (12% with ITC), the recipient must pay GST at 5% (without ITC) or 12% (with ITC) under RCM. The choice of rate is exercised by the GTA at the start of the financial year.

What is a self-invoice under RCM?

A self-invoice is a document prepared by the registered recipient themselves to record an inward supply from an unregistered supplier where RCM applies. It substitutes for the supplier's GST invoice (since the unregistered supplier cannot issue a GST invoice) and is required to support the ITC claim on RCM paid. It must include the supplier's details, goods/service description, taxable value, and GST calculated at the applicable rate.

What is Section 9(4) of the CGST Act and does it apply in 2026?

Section 9(4) originally required RCM on all purchases from unregistered dealers, but was suspended in 2017 due to the compliance burden. In its current amended form, it applies only to specific notified categories of registered persons and goods/services — not to all unregistered purchases. For most businesses in 2026, routine purchases from small unregistered vendors do not attract RCM under Section 9(4). However, composition dealers must pay RCM on all purchases from unregistered suppliers under Section 10(4).

Can you claim ITC on GST paid under RCM?

Yes — provided the following conditions are met: (1) the supply is used for business purposes, (2) RCM has actually been paid in cash, (3) a self-invoice has been issued, (4) the supply is not in the blocked credit list under Section 17(5), and (5) ITC is claimed within the prescribed time limits. ITC on RCM can be claimed in the same tax period in which the RCM was paid.

What are the penalties for not paying RCM?

Failure to pay RCM attracts: (1) interest at 18% per annum on the unpaid tax from the due date, (2) a penalty of 10% of the tax evaded (minimum ₹10,000), and (3) up to 100% penalty if evasion intent is established during investigation. If ITC was wrongly claimed on unpaid RCM, the ITC must be reversed along with its own interest and penalty, effectively doubling the financial burden.
