Reverse Charge Mechanism (RCM) Under GST in India 2026: A Complete Guide for Businesses

18 June 2026

The most GST transactions follow a simple pattern; the supplier charges GST, collects it from the buyer, and deposits it with the government. The reverse charge mechanism flips that. Under RCM, the buyer, not the seller, is responsible for paying GST directly to the government.

For many businesses, this comes as a surprise the first time they encounter it. If you're new to GST compliance, first understand the basics of GST through our guide on What is GST and Types of GST in India. This guide covers everything you need to know about RCM under GST in India for 2026, including which transactions it applies to, how to handle ITC, and the compliance steps you shouldn't skip.

What Is the Reverse Charge Mechanism (RCM) Under GST?

Under the standard GST framework (called "forward charge"), the supplier charges GST on the invoice, collects it from the recipient, and pays it to the government. Under RCM, the obligation to pay GST shifts to the recipient of the goods or services.

In plain terms, if you buy something covered under RCM, you have to pay GST on that purchase yourself even if the seller didn't charge you any.

This doesn't mean you pay more overall. If your business is GST registered and eligible, you can typically claim that RCM payment back as an input tax credit. But the compliance burden sits with you, the buyer, not the supplier.

Why RCM Exists — The Logic Behind It

The government introduced RCM primarily to plug tax leakage in situations where compliance is difficult to enforce.

Consider this: if a small unregistered vendor supplies goods to a large company, the vendor isn't in the GST system at all. There's no mechanism to collect tax from them. But the transaction still has taxable value. By shifting tax liability to the registered recipient who is already filing GST returns, the government ensures tax gets collected.

RCM also applies to certain notified goods and services where the government has decided that buyer-side tax payment makes administrative sense. This covers sectors like goods transport agencies, legal services, and imports of services.

Legal Basis: Section 9(3) and Section 9(4) of the CGST Act

RCM under GST draws from two provisions of the Central Goods and Services Tax Act, 2017.

Section 9(3) covers specific goods and services notified by the government. For these, RCM applies regardless of whether the supplier is registered. The government issues notifications listing exactly which categories fall here.
Section 9(4) covers purchases from unregistered suppliers. A registered person buying goods or services from an unregistered dealer may be required to pay GST on a reverse charge. This provision has been modified multiple times since 2017; its current scope is narrower and applies only to specific categories notified by the government.

Parallel provisions exist under the IGST Act (Sections 5(3) and 5(4)) for interstate supplies.

Who Is Liable to Pay Tax Under RCM?

The GST liability under RCM falls on the registered recipient of the goods or services. A few important points:

The supplier does not charge GST on the invoice for RCM transactions
The recipient pays GST directly to the government (not to the supplier)
The recipient must self-invoice if the supplier is unregistered; this is a separate document required for ITC claims
The recipient is responsible for filing RCM details in GSTR-3B (Table 3.1(d)) and GSTR-2B

Businesses that have not yet obtained registration should first check the GST registration process and eligibility requirements.

RCM on Purchases From Unregistered Suppliers

This is where most confusion arises for small and mid-size businesses.

When a GST-registered business purchases goods or services from an unregistered person, Section 9(4) may apply. However, the current position (post-2019 amendments) is that Section 9(4) applies only to notified categories, not to all purchases from unregistered suppliers.

Self-invoicing requirement: If RCM applies and the supplier is unregistered, you must issue a self-invoice on the date of receipt. This document serves as the tax invoice for the transaction and is required to claim ITC. If you are applying for a GSTIN for the first time, refer to our GSTIN application guide.
Payment timeline: RCM tax must be paid in cash (not by offsetting against ITC). You cannot use your ITC balance to discharge RCM liability. The payment must be made by the 20th of the month following the transaction.

Input Tax Credit (ITC) on RCM — What's Allowed and What Isn't

Yes, you can claim ITC on tax paid under RCM, but with conditions.

What's allowed:

ITC on RCM tax is available once the tax is actually paid in cash to the government
The self-invoice (in case of unregistered supplier) acts as the supporting document
Credit is available only in the tax period in which payment is made, not before

What's not allowed:

ITC cannot be used to pay RCM liability (payment must be in cash)
ITC on RCM is not available if the goods/services are used for exempt supplies or personal use
Blocked credits under Section 17(5) apply; for example, motor vehicle purchases, food and beverages, and certain construction services are blocked regardless of RCM

One practical implication: your cash flow takes a hit when RCM applies, even if you ultimately recover the credit. The cash payment goes out first; the credit comes back later in the same period (if eligible).

How to Comply With RCM

Step 1: Identify RCM Transactions

Each time you make a purchase, check whether it falls under Section 9(3) (notified list) or Section 9(4) (unregistered supplier in notified categories). Keep a working list of your regular suppliers and transaction types.

Step 2: Issue a Self-Invoice (If Supplier Is Unregistered)

If you're buying from an unregistered person, create a self-invoice. This should include the supplier's name and address, the nature of supply, the taxable value, the applicable GST rate, and the RCM declaration.

Step 3: Pay GST in Cash

Calculate the GST due (CGST + SGST for intra-state, or IGST for inter-state). Pay this amount in cash via your electronic cash ledger on the GST portal before the 20th of the following month.

Step 4: Report in GSTR-3B

Report RCM tax liability in Table 3.1(d) of GSTR-3B. This is separate from your outward supply liability.

Step 5: Claim ITC (If Eligible)

After paying the RCM tax, claim the eligible ITC in Table 4 of GSTR-3B. Make sure the goods/services are used for taxable business purposes and are not on the blocked credit list.

Step 6: Reconcile With GSTR-2B

Verify that RCM details auto-populated in GSTR-2B match what you've reported. Discrepancies can trigger notices.

RCM vs Forward Charge: A Quick Comparison

Aspect	Forward Charge	Reverse Charge
Who pays GST	Supplier	Recipient
Invoice type	Tax invoice from supplier	Self-invoice by recipient (if supplier unregistered)
ITC availability	Available to recipient	Available to recipient after cash payment
Cash flow impact	The recipient pays supplier (includes GST)	The recipient pays government directly
Applicable to	All regular taxable supplies	Notified goods/services + unregistered supplier categories
Registration requirement	The supplier must be registered	The recipient must be registered

Common Mistakes Businesses Make With RCM

Not identifying RCM applicability at the time of purchase - Many businesses realize they missed RCM liability only at the time of filing, leading to interest and penalties.
Using ITC balance to pay RCM tax - This is specifically not allowed. RCM must be paid in cash.
Not issuing a self-invoice - Without a self-invoice, your ITC claim on RCM transactions is on shaky ground. The GST department can deny it during scrutiny.
Treating the RCM tax payment as the end of the matter - Many businesses pay RCM in GSTR-3B but forget to claim the corresponding ITC. That's money left on the table.
Incorrect time of supply - For RCM, the time of supply is the earliest of: the date of payment, the 60th day from the supplier's invoice date, or the date of self-invoice. Getting this wrong affects which period's return the liability falls in.
Not tracking partial exemption - If your business makes both taxable and exempt supplies, the ITC on RCM is subject to proportionate reversal under Rule 42/43.

Conclusion

Businesses that are newly registered under GST should understand both registration compliance and reverse charge obligations. The tax doesn't announce itself; you have to know which transactions trigger it, generate the right paperwork, pay in cash, and then recover the credit correctly. Miss any step and you're either over-paying, under-paying, or leaving ITC unclaimed.

For most businesses, the biggest risk isn't understanding the rules; it's not having a system to catch RCM transactions at the point of purchase before they snowball into a filing mess. A simple checklist of your regular suppliers and transaction types, reviewed quarterly against updated CBIC notifications, goes a long way.

If your business regularly deals with goods transport agencies, legal counsel, directors' remuneration, or imports of services, RCM touches you every month. Building it into your accounting workflow from the start is worth the effort.

When in doubt, consult a GST practitioner, particularly for newer transaction types or if you're operating across multiple states.

FAQ Section

Q1. What is the Reverse Charge Mechanism under GST?

RCM is a GST provision where the liability to pay tax shifts from the supplier to the recipient. Instead of the supplier charging GST on the invoice, the buyer pays it directly to the government.

Q2. Which services are compulsorily covered under RCM?

Services covered include goods transport agency services, legal services by advocates, services by arbitral tribunals, sponsorship services, services by directors to companies, insurance agent services, and import of services from foreign providers, among others listed in the government notifications under Section 9(3).

Q3. Can I use my ITC balance to pay RCM tax?

No. RCM tax must be paid in cash from the electronic cash ledger. You cannot offset it against your existing ITC balance. Once paid in cash, the corresponding ITC can be credited in the same tax period (subject to eligibility).

Q4. Do I need to issue a self-invoice for every unregistered purchase under RCM?

Only if the purchase falls under a notified category under Section 9(4). Not all purchases from unregistered suppliers trigger RCM in 2026; the scope is limited to specific categories notified by the CBIC.

Q5. When is the time of supply under RCM for services?

The time of supply of services under RCM is the earlier of the date of payment or 60 days from the date of the supplier's invoice. If neither can be determined, the date of entry in the recipient's books is used.

Q6. Is RCM applicable for imports?

Yes. The import of services is taxable under IGST on a reverse charge basis, regardless of whether the foreign supplier is GST-registered. The Indian recipient must pay IGST and can claim ITC on it.

Q7. What happens if I miss reporting RCM liability?

Undeclared RCM liability attracts interest at 18% per annum from the due date, plus a penalty of 10% of the tax amount (minimum Rs. 10,000). In cases of fraud or deliberate evasion, the penalty can go up to 100% of the tax due.

Q8. Can a composition dealer purchase from a GTA?

No. Composition dealers cannot pay tax under RCM and are therefore not eligible to receive services covered under RCM like GTA services. If they do, they lose their composition status eligibility.

Q9. Does RCM apply to e-commerce transactions?

Transactions facilitated by e-commerce operators have their own tax rules under Section 9(5). These are distinct from standard RCM under Section 9(3) or 9(4), though the underlying concept of liability shifting to a party other than the direct supplier is similar.

Q10. How do I report RCM in GST returns?

Report RCM liability in Table 3.1(d) of GSTR-3B. The ITC claimed that the RCM payment goes in Table 4(A)(3). Self-invoices issued for unregistered purchases should also be reported in GSTR-1 (Table 4B).
