Reverse Charge Mechanism under GST: Rules, Applicability and Examples

Reverse Charge Mechanism under GST changes the normal process of tax collection. Normally, the supplier collects GST from the customer and pays it to the Government. Under reverse charge, the recipient of the goods or services becomes responsible for paying GST directly to the Government.

This mechanism applies only to supplies notified under the GST law. It is not applicable to every purchase from an unregistered supplier. A business must first check whether the particular goods or service is covered by a reverse-charge notification.

What is Reverse Charge Mechanism under GST?

Under the normal forward-charge system, the supplier issues a tax invoice, collects GST from the recipient and reports the transaction in the applicable GST return.

Under reverse charge, the recipient pays the applicable GST instead of the supplier. The recipient may be required to issue the relevant document, record the liability in the GST return and pay the tax through the electronic cash ledger.

Reverse charge provisions mainly arise under Section 9(3) and Section 9(4) of the CGST Act. Similar provisions apply to inter-State supplies under Section 5(3) of the IGST Act.

When does reverse charge apply?

Reverse charge can apply in the following broad situations:

Specified goods or services notified by the Government
Specified supplies received by a registered person from an unregistered supplier, where the law specifically applies
Certain services supplied by notified categories of suppliers
Specified transportation, legal, sponsorship or other notified services
Import of services from a supplier located outside India, where the recipient is liable under the applicable provisions

The exact list is controlled by notifications issued under the CGST Act, IGST Act and related rules. Since the notified list can change, businesses should verify the current notification before treating a transaction as liable to reverse charge.

Examples of supplies that may attract reverse charge

Depending on the applicable notification and conditions, common examples may include certain legal services supplied by an advocate, specified goods transport services, sponsorship services and selected services supplied by directors to their company.

These examples are not automatic in every transaction. The supplier type, recipient status, place of supply and other conditions must be checked before applying reverse charge.

Who pays GST under reverse charge?

The recipient pays the GST when the supply is covered by a reverse-charge provision. The recipient should calculate the tax on the taxable value and apply the correct CGST and SGST or IGST treatment.

For an intra-State supply, CGST and SGST or UTGST may apply. For an inter-State supply, IGST may apply. The place-of-supply rules should be checked before deciding the tax type.

Registration requirement

A person liable to pay tax under reverse charge may be required to obtain GST registration even if turnover is below the normal registration threshold, subject to the applicable law and exemptions.

Small businesses should not assume that low turnover always removes the registration requirement. Review the registration provisions and the relevant notification before accepting a notified reverse-charge supply.

For an overview of the registration process, read our GST Registration in India guide.

Self-invoice and payment voucher

When the recipient is liable to pay GST on a supply received from an unregistered supplier, the recipient may need to issue a self-invoice as prescribed under the GST rules. A payment voucher may also be required when making payment to the supplier in the specified circumstances.

The document should contain the required particulars, including the date, serial number, supplier and recipient details, description of the supply, taxable value, tax rate and tax amount.

Self-invoice requirements do not apply in exactly the same way to every reverse-charge transaction. Check the type of supply and the applicable rule before creating the document.

How to report reverse charge in GST returns

The recipient should report the reverse-charge liability in the applicable GST return, including the relevant section of GSTR-3B where required.

The tax must generally be paid through the electronic cash ledger. Input tax credit cannot normally be used to pay the reverse-charge liability. After paying the tax and satisfying the conditions under the ITC rules, the recipient may claim eligible input tax credit in the return.

For related return guidance, see our article on GSTR-1 and GSTR-3B.

Example of reverse-charge calculation

Particular	Amount
Value of notified service	₹50,000
Assumed GST rate for illustration	18%
GST payable under reverse charge	₹9,000

If the supply is intra-State, the ₹9,000 may be divided between CGST and SGST. If it is inter-State, IGST may apply. The recipient should first confirm that the service is actually covered by reverse charge and then verify the current rate.

Input tax credit of reverse-charge GST

After paying the reverse-charge tax, the recipient may claim eligible input tax credit if the goods or services are used or intended for business and all Section 16 conditions are satisfied.

Credit remains subject to blocked-credit rules, exempt-supply reversals, document requirements and other restrictions. Paying reverse-charge tax does not automatically make the full amount eligible for ITC.

Time of supply under reverse charge

The time of supply for reverse-charge transactions follows special rules. For goods and services, the relevant date can depend on the date of receipt, payment or the date immediately after the prescribed period from the supplier’s invoice.

Because the time-of-supply rules differ between goods and services, businesses should maintain the invoice date, receipt date and payment date in their records.

Common mistakes to avoid

Applying reverse charge to every purchase from an unregistered supplier
Ignoring reverse-charge notifications
Using the wrong place-of-supply rule
Paying tax through the electronic credit ledger when cash payment is required
Claiming ITC before paying the reverse-charge tax
Failing to issue a required self-invoice or payment voucher
Reporting the liability in the wrong return period
Claiming blocked or personal-use credit

Reverse charge and normal GST invoice rules

A reverse-charge transaction still requires proper documentation. The supplier’s invoice, recipient’s self-invoice, payment voucher, tax calculation and GST return should agree with one another.

Conclusion

Reverse Charge Mechanism under GST transfers the tax-payment responsibility from the supplier to the recipient for specified transactions. The recipient must identify the applicable notification, calculate the correct tax, issue the required documents, pay through the prescribed method and claim ITC only when eligible.

Always verify the latest CBIC notifications, GST rules and GST Portal instructions before applying reverse charge to a transaction.
