What is the reverse charge mechanism in GST?

Normally the seller collects GST from the buyer and pays it to the government. Under the reverse charge mechanism the responsibility flips: the buyer (recipient) pays the GST directly to the government instead of the supplier collecting it. It applies only to specific notified supplies and situations, not to ordinary sales.

When does reverse charge apply?

RCM applies in defined cases, such as certain notified categories of goods and services, and supplies received from an unregistered person in specific situations. Common real-world triggers include some goods transport (freight), legal services from an advocate, and a few other notified services. Because the list is specific and changes over time, check the current notifications for your exact supply rather than assuming.

Do I need to raise a self-invoice under RCM?

Yes, when you receive a supply liable to reverse charge from an unregistered supplier, you as the recipient are required to issue a self-invoice for it and, where applicable, a payment voucher. This creates the document trail the tax needs, since the supplier did not raise a GST invoice. Registered suppliers under RCM will usually mention that tax is payable on reverse charge on their invoice.

Can I claim input tax credit on GST paid under reverse charge?

Generally yes, provided the input or service is used for your business and is otherwise eligible. You first pay the reverse-charge tax in cash (it cannot be set off against input credit at the payment stage), and then you can claim that amount back as input tax credit in the same or a later period, subject to the normal conditions. So for eligible purchases it is often cash-flow timing rather than a permanent cost.

How do I show reverse charge in my GST return?

Reverse-charge liability is reported and paid through your regular return (GSTR-3B), where there are specific fields for tax payable under reverse charge and for the input credit you then claim on it. Keep the self-invoices and supplier documents so the figures reconcile if questioned.

Reverse Charge Mechanism (RCM) in GST: A Plain Guide for 2026

In most GST transactions the seller adds GST to the bill, collects it, and pays it to the government. The reverse charge mechanism, or RCM, turns that around for certain supplies: the buyer pays the GST directly instead. It surprises many small business owners the first time they hit it, usually on freight or legal fees, so it is worth understanding before it appears on your books.

This plain guide explains what reverse charge means, the common cases where it applies, how to raise a self-invoice, how the tax is paid and reported, and when you can claim it back as input credit. Because the notified list of RCM supplies is specific and is updated over time, always confirm the current position for your exact goods or service.

What reverse charge actually means

Under normal (forward) charge, GST flows seller to government via the invoice. Under reverse charge, the law makes the recipient liable to pay the GST. You are effectively both the buyer and the person who deposits the tax. It applies only to specified categories, so it is the exception, not the rule, but when it applies it is mandatory, and ignoring it creates a liability you did not collect from anyone.

Common cases where RCM applies

The precise list is set by notification, but the situations small businesses meet most often include:

Goods transport / freight from a transporter in defined cases;
Legal services received from an advocate or a firm of advocates;
certain other notified services (for example some sponsorship or director-related services); and
specific supplies received from an unregistered person where the law requires the registered recipient to pay.

If you pay a transporter for delivery or an advocate for advice, there is a good chance reverse charge is in play, so check before you assume the supplier handled the tax.

Self-invoicing and vouchers

When you receive an RCM supply from an unregistered supplier, you must issue a self-invoice for it, because no GST invoice came from the other side. Where a payment is made, a payment voucher is also required. This paperwork gives the transaction a proper document trail and is what lets you later claim the input credit. A registered supplier under RCM will typically state on their invoice that tax is payable by the recipient under reverse charge.

How the tax is paid and reported

Reverse-charge tax must be paid in cash; you cannot set it off against your input credit balance at the moment of payment. You report the liability in your regular monthly return (GSTR-3B), in the fields meant for tax payable under reverse charge, and pay it. Missing this is a common error because the amount never appeared as GST you collected, so it is easy to overlook.

Claiming it back as input credit

The good news for most business purchases: after paying the reverse-charge tax, you can usually claim it as input tax credit in the same or a later period, provided the goods or services are used for your business and are otherwise eligible. So for eligible inputs, RCM is often a timing and paperwork matter rather than a permanent extra cost. For blocked or personal-use items, the credit is not available and the tax is a real cost.

Keep the trail tidy

Reverse charge lives or dies on documentation: the self-invoice, the supplier's paperwork, the return entries, and the credit claim all need to line up. If your billing and records are organised, RCM is a manageable routine; if they are scattered, it becomes the entry that trips up a filing.
