Quick Answer
Under the Reverse Charge Mechanism (RCM), the recipient of goods or services pays GST directly to the government instead of the supplier. It applies to certain notified goods and services, imports of services, and some purchases from unregistered suppliers. If RCM applies to you, you must register for GST (no turnover limit), pay the tax in cash, issue a self-invoice where the supplier is unregistered, and you can usually claim it back as input tax credit.
In a normal GST transaction, the seller collects tax from the buyer and deposits it with the government. The Reverse Charge Mechanism flips this around. Under RCM, the buyer — not the seller — becomes responsible for paying the GST. It sounds unusual, but the government uses it to collect tax in situations where the supplier is hard to track, such as imports or supplies by small, unregistered vendors. If you run a business and buy services like transport or legal advice, RCM very likely affects you. Let's break it down in simple terms.
What is the Reverse Charge Mechanism?
Reverse charge is a method of collecting GST where the liability to pay tax shifts from the supplier to the recipient. Instead of the supplier adding GST to the bill and paying it, the recipient calculates the GST, pays it to the government, and reports it in their returns. The legal backbone for this is found in Section 9(3) and Section 9(4) of the CGST Act (and the matching provisions of the IGST Act for imports). If you're still getting familiar with the basics, our GST full form & meaning guide is a good starting point.
Forward Charge vs Reverse Charge
| Basis | Forward Charge | Reverse Charge (RCM) |
|---|---|---|
| Who pays GST | Supplier | Recipient (buyer) |
| Tax on invoice | Charged by supplier | Not charged; buyer self-accounts |
| Payment mode | Cash or ITC | Cash only |
| Common in | Most transactions | Notified goods/services, imports |
When Does Reverse Charge Under GST Apply?
RCM is not something you can choose — it applies automatically in specific situations. There are three main triggers:
- Notified goods and services [Section 9(3)] — the government publishes lists of goods and services on which the recipient must pay GST.
- Supply by an unregistered person to a registered person [Section 9(4)] — applies to notified categories, such as certain purchases by real-estate promoters.
- Import of services — when you receive a service from outside India, you pay IGST under reverse charge.
The exact lists are updated from time to time, so always cross-check the latest GST notifications before deciding whether RCM applies to a transaction.
Reverse Charge on Goods
Certain goods attract reverse charge when supplied by specified persons. Common examples from the notified list include:
- Cashew nuts (not shelled/peeled) supplied by an agriculturist
- Tobacco leaves and bidi wrapper leaves (tendu)
- Raw cotton supplied by an agriculturist
- Silk yarn
- Supply of lottery
- Used vehicles, seized/confiscated goods and scrap supplied by the government to a registered person
Reverse Charge on Services
Services are where most businesses actually encounter RCM. Widely applicable examples include:
- Goods Transport Agency (GTA) services — the recipient often pays GST at 5% under RCM
- Legal services by an advocate or law firm to a business
- Director's services (like sitting fees) to a company
- Sponsorship services provided to a body corporate or partnership
- Services by an insurance agent or recovery agent
- Import of services such as foreign software, consulting or subscriptions
- Renting of motor vehicles and security services in specified cases

Registration Rules Under RCM
Here's a point many businesses miss: if you are liable to pay tax under reverse charge, you must register for GST regardless of your turnover. The usual threshold exemption does not apply. So even a small business below the normal limit has to register the moment an RCM liability arises. Check the details in our guide to the GST registration threshold limit, and keep the registration documents checklist handy.
Self-Invoicing and Payment Voucher
When you buy from an unregistered supplier and RCM applies, the supplier obviously can't raise a GST invoice. So the law requires you, the recipient, to:
- Issue a self-invoice for the supply received, and
- Issue a payment voucher at the time of paying the supplier.
These documents keep your records clean and support your input tax credit claim later.
How to Pay and Report RCM
Two rules matter most here. First, RCM tax must be paid in cash through your electronic cash ledger — you cannot use input tax credit to discharge a reverse charge liability. Second, you report it in your returns:
- Declare the RCM liability in Table 3.1(d) of your GSTR-3B.
- Claim the eligible ITC in Table 4 of the same return.
- Reconcile with your GSTR-2B where applicable.

Input Tax Credit (ITC) Under RCM
The good news is that the tax you pay under reverse charge is usually not a permanent cost. Once you've paid it in cash, you can claim it back as input tax credit — provided the goods or services are used for your business and meet the normal ITC conditions. In effect, RCM is often revenue-neutral, though it does affect your cash flow because you pay first and claim credit later. Review the eligibility rules in our guide on the conditions to claim ITC under GST.
One important exception: businesses under the composition scheme must pay RCM at normal rates but cannot claim the credit.
Time of Supply Under RCM
The "time of supply" decides when your RCM liability arises. The rules differ for goods and services:
| Supply | Time of Supply (earliest of) |
|---|---|
| Goods | Date of receipt of goods, date of payment, or 30 days from the invoice date |
| Services | Date of payment, or 60 days from the invoice date |
Common RCM Mistakes to Avoid
- Forgetting to register when the first RCM liability arises.
- Trying to pay RCM using ITC instead of cash.
- Missing self-invoices for purchases from unregistered suppliers.
- Not reporting RCM in the correct GSTR-3B tables.
- Overlooking RCM on imported services and subscriptions.
Errors here can snowball into a GST demand, assessment, or even litigation — so it pays to get the process right from day one.
Frequently Asked Questions
Who pays GST under reverse charge?
The recipient (buyer) of the goods or services pays GST directly to the government, instead of the supplier collecting and paying it.
Is registration mandatory for RCM?
Yes. Any person liable to pay tax under reverse charge must register for GST regardless of turnover — the normal threshold exemption does not apply.
Can I use input tax credit to pay RCM?
No. RCM liability must be paid in cash through the electronic cash ledger. You can, however, claim the amount back as ITC afterwards if eligible.
Do I need to issue a self-invoice under RCM?
Yes, when you receive a supply from an unregistered person under RCM, you must issue a self-invoice and a payment voucher.
Does RCM apply to imported services?
Yes. When you receive services from a supplier located outside India, you pay IGST under reverse charge.
Conclusion
The Reverse Charge Mechanism can feel counter-intuitive at first — after all, you're paying tax on something you bought. But once you understand the logic, it's manageable: identify whether the supply is notified, register if required, pay the tax in cash, keep proper self-invoices, and claim your credit. The businesses that run into trouble are usually the ones that don't realise RCM applied until a notice arrives. A little awareness up front saves a lot of stress later. When a transaction sits in a grey area, a quick expert check is always worth it.
