Understood. Below is a professionally readable version with the structure corrected. I have used paragraphs for the legal explanation, bullet points only where they improve clarity, and tables only for the notified goods and services, where tabular presentation is actually useful.
The Reverse Charge Mechanism (RCM) under GST is the statutory mechanism under which the recipient of goods or services becomes liable to pay tax instead of the supplier. This is an exception to the normal charging system of GST, under which the supplier collects and pays the tax. Reverse charge applies only where the law specifically provides for it or where the Government has notified the supply under the relevant statutory power.
The legal basis of reverse charge is found primarily in section 9(3) and section 9(4) of the CGST Act, 2017, and section 5(3) of the IGST Act, 2017. These provisions are operationalised through notifications issued by the Government on the recommendation of the GST Council.
The reverse charge framework therefore rests on the following statutory provisions:
- Section 9(3), CGST Act – notified goods and services
- Section 9(4), CGST Act – notified inward supplies received from unregistered suppliers
- Section 5(3), IGST Act – notified interstate supplies
- Section 31(3)(f), CGST Act – recipient-issued invoice in specified cases
- Section 31(3)(g), CGST Act – payment voucher
Section 9(3) of the CGST Act
Section 9(3) authorises the Government to notify categories of goods or services on which the recipient shall pay GST on reverse charge basis. Once a supply is notified under this subsection, the recipient is treated as the person liable to pay tax for that transaction. The supplier does not discharge tax in the normal forward charge manner for that notified entry.
The principal notifications issued under this subsection are:
- Notification No. 04/2017-Central Tax (Rate), dated 28.06.2017 for notified goods
- Notification No. 13/2017-Central Tax (Rate), dated 28.06.2017 for notified services
The effect of section 9(3) is that:
- the liability shifts to the recipient
- the recipient must compute and pay the tax
- the recipient must comply with documentation and return requirements applicable to reverse charge transactions
Section 9(4) of the CGST Act
Section 9(4) deals with reverse charge in respect of specified inward supplies received by a registered person from an unregistered supplier, but only to the extent notified by the Government. This provision does not apply generally to every purchase from an unregistered person. Its operation is confined to notified classes of recipients or notified categories of supply.
The provision presently covers, among other notified cases:
- specified procurements by promoters in the real estate sector
- renting of immovable property other than residential dwelling by an unregistered person to a registered person, introduced through Notification No. 09/2024-Central Tax (Rate), with later CBIC material noting exclusion for composition taxpayers.
Section 5(3) of the IGST Act
Section 5(3) of the IGST Act is the corresponding reverse charge provision for interstate supplies. It empowers the Government to notify categories of interstate supplies on which the recipient is liable to pay IGST. This provision operates in the same manner as section 9(3) of the CGST Act, except that the tax discharged is IGST.
Its practical effect is that:
- the recipient becomes the taxable person for the notified interstate supply
- IGST is payable under reverse charge
- import of services is also dealt with within this framework
Import of Services
Where a person located in India receives services from a supplier located outside India and the place of supply is in India, the transaction is treated as import of services. Import of services is treated as an interstate supply, and IGST is payable by the recipient under reverse charge.
Accordingly:
- the recipient in India pays IGST
- the payment is made under reverse charge
- input tax credit may be claimed after payment, subject to sections 16 and 17 of the CGST Act
Documentation and Compliance
Reverse charge requires recipient-side documentation. Section 31(3)(f) of the CGST Act requires the recipient to issue an invoice in applicable reverse charge cases, and section 31(3)(g) requires the issue of a payment voucher at the time of payment to the supplier. The significant compliance change is the insertion of Rule 47A by Notification No. 20/2024-Central Tax dated 08.10.2024, effective from 01.11.2024. Rule 47A provides that where an invoice is required to be issued under section 31(3)(f) by a registered person liable to pay tax under section 9(3) or section 9(4), such invoice must be issued within 30 days from the date of receipt of the goods or services or both.
The compliance position may therefore be stated as follows:
- Self-invoice is required under section 31(3)(f) in applicable cases.
- Payment voucher is required under section 31(3)(g) at the time of payment.
- Rule 47A prescribes a 30-day time limit for issuing the recipient invoice.
- Reverse charge tax must be paid through the electronic cash ledger.
- Input tax credit cannot be used for payment of the reverse charge liability itself.
- ITC may be availed only after payment of tax, subject to eligibility and restrictions under sections 16 and 17.
Time of Supply under Reverse Charge
The time of supply provisions determine the point at which the reverse charge liability arises. Rule 47A deals only with the time for issuing the recipient invoice; it does not replace the statutory time of supply provisions.
For goods, section 12(3) of the CGST Act applies. The time of supply is the earliest of the following:
- the date of receipt of goods
- the date of payment
- the day immediately following 30 days from the date of the supplier’s invoice
If none of the above can be determined, the time of supply is the date of entry in the books of account of the recipient.
For services, section 13(3) of the CGST Act applies. The time of supply is the earliest of:
- the date of payment
- the day immediately following 60 days from the date of the supplier’s invoice
If these cannot be determined, the time of supply is the date of entry in the books of account of the recipient.
Notified Goods under Reverse Charge
The principal notification for goods is Notification No. 04/2017-Central Tax (Rate). The core notified goods are as follows.
| Sl. No. | Goods | Supplier | Recipient liable |
|---|---|---|---|
| 1 | Cashew nuts, not shelled or peeled | Agriculturist | Registered person |
| 2 | Bidi wrapper leaves (tendu leaves) | Agriculturist | Registered person |
| 3 | Tobacco leaves | Agriculturist | Registered person |
| 4 | Silk yarn | Specified supplier | Registered person |
| 5 | Raw cotton | Agriculturist | Registered person |
| 6 | Used vehicles, seized and confiscated goods, old and used goods in notified Government cases | Government / local authority | Registered person |
A separate 2024 development concerns metal scrap. CBIC’s 54th GST Council press release records the decision to introduce reverse charge on supply of metal scrap by an unregistered person to a registered person, and also records 2% TDS on B2B supply of metal scrap by a registered person. This should be treated as a current compliance update and checked against the exact rate notification text before final filing or publication use.
Notified Services under Reverse Charge
The principal notification for services is Notification No. 13/2017-Central Tax (Rate), read with later amendments. The current professional summary is set out below.
| Sl. No. | Service | Supplier | Recipient liable |
|---|---|---|---|
| 1 | Goods Transport Agency services | GTA | Specified recipients |
| 2 | Legal services | Individual advocate / firm of advocates | Business entity |
| 3 | Services by arbitral tribunal | Arbitral tribunal | Business entity |
| 4 | Sponsorship services | Non-body corporate supplier | Body corporate or partnership firm |
| 5 | Specified services by Government / local authority | Government / local authority | Business entity / registered person, as applicable |
| 6 | Renting of immovable property by Government in notified cases | Government / local authority | Registered person / business entity, as applicable |
| 7 | Services by director | Director | Company / body corporate |
| 8 | Insurance agent services | Insurance agent | Insurer |
| 9 | Recovery agent services | Recovery agent | Bank / financial institution / NBFC |
| 10 | Specified copyright-related services | Author / artist / specified person | Publisher / producer / specified recipient |
| 11 | Security services | Non-body corporate supplier | Registered person, subject to conditions |
| 12 | Renting of residential dwelling | Any person | Registered person |
| 13 | Renting of immovable property other than residential dwelling | Unregistered person | Registered person |
Two service-side updates require specific attention:
- Commercial immovable property rent by an unregistered person to a registered person was introduced under reverse charge through Notification No. 09/2024-Central Tax (Rate).
- Sponsorship services supplied by a body corporate were shifted to forward charge, leaving reverse charge applicable where the supplier is a non-body corporate. CBIC materials refer to this change through Notification No. 07/2025-Central Tax (Rate).
