Reverse Charge Mechanism Under GST: Complete Guide

What if the supplier does not collect GST from you—but your business still has to pay it?

That is the basic idea behind the Reverse Charge Mechanism (RCM) under GST.

Under the normal GST mechanism, the supplier collects GST from the recipient and pays it to the government. Under reverse charge, however, the responsibility to pay GST shifts to the recipient for specified categories of supplies and circumstances.

For businesses, RCM can become complicated because the transaction does not always look like a conventional GST purchase. The accounting team may receive an invoice without GST, yet the business may still have a GST liability to report and pay.

The GST Portal currently provides a specific reporting mechanism for inward supplies liable to reverse charge in Table 3.1(d) of GSTR-3B. The corresponding eligible ITC is separately reported in Table 4A(3).

Understanding when RCM applies, how the liability is calculated and how the related ITC is treated is therefore an important part of GST compliance.

What Is Reverse Charge Mechanism Under GST?

Reverse Charge Mechanism means that, instead of the supplier being liable to pay GST, the recipient becomes liable to pay GST for specified supplies or circumstances under GST law.

The basic difference can be understood as:

Normal GST

Supplier → Charges GST → Collects GST → Pays GST to Government

Reverse Charge

Recipient → Determines RCM liability → Pays GST to Government

The recipient must therefore identify applicable RCM transactions during its regular accounting and GST review.

RCM is not applicable to every purchase from an unregistered or registered supplier. It applies only where the GST law or relevant notification specifically provides for reverse charge.

CBIC maintains notifications specifying categories of supplies on which tax is payable under reverse charge, including notifications under the CGST and IGST frameworks.

Why Is RCM Important for Businesses?

RCM transactions can be easily missed because the GST may not appear in the supplier's invoice in the same way as an ordinary taxable purchase.

For example, a business may receive a professional service invoice of:

Professional fee: ₹1,00,000

The accounting team may record ₹1,00,000 as an expense and pay the supplier ₹1,00,000.

But if the particular transaction is covered by an applicable RCM provision, the recipient may separately have a GST liability.

If the accounting team does not identify the transaction, the business could under-report its GST liability.

RCM should therefore be treated as a separate compliance checkpoint.

When Does Reverse Charge Apply?

RCM generally arises in specified circumstances rather than as a blanket rule for all purchases.

Broadly, businesses should consider three important categories:

1. Supplies Specifically Notified Under the CGST Act

Section 9(3) provides the framework under which the Government may notify categories of supplies on which tax is payable by the recipient under reverse charge.

The relevant notifications specify the supplies and circumstances covered.

2. Certain Supplies Covered by Section 9(4)

Section 9(4) deals with specified categories of supplies received by specified classes of registered persons from unregistered suppliers, subject to the conditions and notifications applicable to the provision.

Businesses should therefore not assume that every purchase from an unregistered supplier automatically attracts RCM.

The specific statutory conditions need to be checked.

3. Import of Services

Certain services received from outside India can create an RCM liability in India where the applicable GST provisions treat the recipient as liable to pay tax.

This is particularly relevant for businesses purchasing:

• Foreign consulting services
• Software or digital services
• Professional services
• Technical services
• Other cross-border services

The exact GST treatment depends on the nature of the transaction and applicable place-of-supply and import-of-services provisions.

Common RCM Transactions Businesses Should Review

The exact list of notified RCM supplies can change through notifications, so businesses should verify the applicable notification for the relevant period.

Depending on the facts, RCM can arise in areas such as:

• Specified legal services
• Certain services supplied by individual advocates or firms of advocates
• Certain services supplied by a director to a company
• Specified services received from outside India
• Certain transport-related services
• Certain notified goods or services
• Other categories specifically notified by the Government

This is why a business should maintain an RCM transaction checklist rather than relying on memory.

RCM on Legal Services

One important area businesses commonly review is legal services covered by the applicable reverse-charge notification.

For example, a company receives a qualifying legal service from an individual advocate.

Instead of assuming that the advocate will charge GST under the normal mechanism, the company should examine whether the service falls within the notified RCM category.

If RCM applies, the recipient must account for the GST liability according to the applicable rules.

The accounting entry and GST return treatment should then be aligned.

RCM on Director's Services

Services supplied by a director to a company can also require careful review.

Businesses should distinguish between different types of payments made to directors and examine the underlying nature of the payment.

For example, director remuneration may have different GST implications depending on whether it represents:

• Salary under an employer-employee relationship
• Fees for services
• Other contractual payments

The accounting classification should therefore not be used as the only basis for deciding whether RCM applies.

The actual legal and contractual nature of the payment must be reviewed.

RCM on Import of Services

Import of services is another important RCM area for businesses.

Suppose a Delhi-based company receives consulting services from a foreign company.

The foreign supplier may not be registered under Indian GST.

That does not automatically mean that GST is irrelevant.

The recipient should examine whether the transaction qualifies as an import of services and whether GST is payable under reverse charge.

This review may involve:

• Supplier location
• Recipient location
• Place of supply
• Nature of service
• Consideration
• Business purpose
• Applicable GST provisions

For businesses regularly purchasing services from overseas vendors, RCM should be included in the monthly accounts-payable review.

Does Every Foreign Service Attract RCM?

No.

A foreign transaction should not automatically be classified as an RCM transaction merely because the supplier is located outside India.

The business should first determine whether the transaction qualifies as an import of services under the applicable GST provisions.

Place of supply and other statutory conditions can affect the GST treatment.

Therefore:

Foreign supplier ≠ automatically RCM

The correct process is:

Foreign transaction → Determine nature → Check import-of-services conditions → Determine GST treatment → Check RCM applicability

How Is RCM Reported in GSTR-3B?

The GST Portal currently provides a specific field for inward supplies liable to reverse charge.

Table 3.1(d) of GSTR-3B is used for inward supplies liable to reverse charge.

The GST Portal states that the relevant reverse-charge liability is auto-drafted from GSTR-2B where applicable.

The taxpayer should nevertheless review the figures and ensure that all applicable RCM transactions have been properly identified.

RCM should be reconciled with the books rather than relying solely on portal auto-population.

Can RCM Tax Be Paid Using ITC?

This is one of the most important practical points.

RCM liability cannot simply be discharged using regular ITC.

The GST Portal specifically states that reverse-charge-related liabilities must be paid through the electronic cash ledger or applicable accumulated negative liability balance, rather than through available ITC.

This means a business needs sufficient cash balance to discharge the RCM tax liability.

For example, suppose:

RCM liability: ₹18,000

The business cannot simply use ₹18,000 of existing ITC to pay that RCM liability.

It needs to discharge the RCM liability through the permitted cash mechanism.

Can ITC Be Claimed on GST Paid Under RCM?

In many eligible cases, GST paid under RCM can subsequently become available as ITC, subject to the applicable ITC conditions and restrictions.

The GST Portal separately identifies:

Table 4A(3): ITC available on inward supplies liable to reverse charge

The portal states that this section covers inward supplies liable to reverse charge other than the specified categories separately identified, with invoices, debit notes and credit notes taken into account on a net basis.

Therefore, businesses should understand that:

RCM liability and RCM ITC are two separate steps.

The sequence is generally:

Identify RCM → Calculate GST → Pay GST in cash → Determine ITC eligibility → Claim eligible ITC

Practical Example of RCM Accounting

Suppose a business receives a qualifying service covered by RCM.

Service value: ₹1,00,000
Applicable GST rate: 18%
RCM liability: ₹18,000

The business records the service expense of ₹1,00,000.

It then recognises the applicable RCM GST liability of ₹18,000.

The ₹18,000 tax must be paid through the permitted cash mechanism.

If the business satisfies the applicable ITC conditions, the eligible ₹18,000 may subsequently be claimed as ITC.

The important point is that the company cannot skip the liability-payment stage simply because it expects to claim the amount as ITC.

RCM and GSTR-2B

GSTR-2B can provide information relevant to certain reverse-charge transactions.

The GST Portal states that reverse-charge liability in GSTR-3B Table 3.1(d) is auto-drafted from GSTR-2B. It also separately auto-populates eligible RCM ITC in Table 4A(3), subject to the relevant data.

However, businesses should not assume:

“If it is not in GSTR-2B, there is no RCM liability.”

The recipient remains responsible for identifying transactions that independently attract RCM.

For example, an import-of-services transaction may require review even if the accounting team does not see a conventional domestic supplier invoice in GSTR-2B.

RCM Reconciliation: What Should Businesses Compare?

A monthly RCM reconciliation can compare:

• Purchase register
• Expense ledger
• Vendor master
• Legal/professional expense ledger
• Foreign service payments
• Director-related payments
• Transportation expenses
• Relevant RCM invoices
• GSTR-2B
• GSTR-3B
• Cash ledger
• RCM liability records
• RCM ITC records

A simple reconciliation tracker can be useful.

The purpose of this tracker is to ensure that RCM does not disappear inside general expense accounts.

How to Identify RCM Transactions From Accounting Data ?

A useful approach is to create an RCM review list from the general ledger.

Review expense categories such as:

• Legal and professional fees
• Director-related payments
• Transportation/freight
• Foreign professional services
• Consulting fees
• Technical services
• Certain government-related payments
• Other categories relevant to the business

Then examine each transaction to determine whether a notified RCM provision applies.

This is more reliable than asking the accountant to remember every RCM category.

RCM and Cash Flow Planning

RCM can also have a cash-flow impact.

Suppose a business has ₹5 lakh of normal GST liability but also has ₹2 lakh of RCM liability.

The company may have substantial ITC available from other purchases.

However, the RCM portion still needs to be paid through the permitted cash mechanism.

This means businesses with significant RCM transactions should forecast the cash requirement before filing the return.

RCM should therefore be considered during monthly tax planning, not only during return preparation.

Common RCM Compliance Mistakes

Mistake 1: Assuming the Supplier Will Pay GST

Under RCM, the recipient is responsible for the applicable tax.

The accounting team should therefore identify the transaction independently.

Mistake 2: Treating Every Unregistered Purchase as RCM

Not every purchase from an unregistered person automatically attracts RCM.

The specific legal provision and applicable notification must be checked.

Mistake 3: Paying RCM Through ITC

The GST Portal specifically states that reverse-charge liabilities must be paid through the permitted cash mechanism.

Mistake 4: Claiming ITC Without Paying the RCM Liability

The liability and ITC stages should be properly accounted for.

Mistake 5: Ignoring Foreign Services

Foreign service payments should be reviewed for import-of-services and RCM implications.

Mistake 6: Treating Director Remuneration as One Category

Salary, professional fees and other payments can have different GST implications.

The underlying nature of the payment should be reviewed.

Mistake 7: Relying Only on GSTR-2B

GSTR-2B is useful, but businesses remain responsible for identifying applicable tax liabilities.

Mistake 8: Not Maintaining an RCM Register

Without a dedicated tracker, recurring RCM transactions can easily be missed.

Monthly RCM Compliance Checklist

A practical monthly process can include:

• Review all expenses for potentially notified RCM transactions.
• Review legal and professional fees.
• Review director-related payments.
• Review foreign service payments.
• Review transportation and other relevant expenses.
• Check applicable RCM notifications.
• Match RCM transactions with GSTR-2B.
• Calculate applicable GST liability.
• Report the liability in GSTR-3B.
• Ensure RCM tax is paid through the permitted cash mechanism.
• Determine whether ITC is eligible.
• Record eligible RCM ITC appropriately.
• Reconcile RCM liability with the cash ledger.
• Reconcile RCM ITC with the ITC ledger.
• Maintain supporting invoices and calculations.

RCM Example for a Business in Delhi

Consider a Delhi-based consulting company that receives:

Legal service: ₹50,000
Foreign consultancy: ₹1,50,000
Regular office purchase: ₹30,000

The accounting team should not simply calculate GST based on the total expenses.

Instead, it should classify each transaction separately.

The legal service should be checked against the applicable RCM notification.

The foreign consultancy should be reviewed to determine whether it qualifies as an import of services and whether RCM applies.

The regular office purchase should be evaluated under the normal GST mechanism.

This transaction-level classification can prevent both missed RCM liabilities and incorrect GST payments.

RCM Compliance for Delhi NCR Businesses

Businesses in Delhi, Noida, Gurugram, Ghaziabad and Faridabad may regularly purchase professional, technical, transportation and overseas services.

RCM review becomes particularly important for:

• IT companies
• Consulting firms
• Export-oriented businesses
• Startups
• Manufacturing companies
• Real estate businesses
• Professional service firms
• Companies using foreign SaaS or consulting vendors
• Businesses with significant legal expenses

Businesses searching for GST RCM services in Delhi, GST consultant in Delhi, RCM compliance services in Noida, or GST compliance consultant in Gurugram should ideally have a monthly process that connects accounting, vendor payments and GST returns.

How Professional GST Compliance Support Helps ?

A structured GST compliance system can help businesses:

• Identify potentially applicable RCM transactions.
• Review relevant notifications.
• Calculate RCM liability.
• Reconcile RCM with accounting records.
• Verify GSTR-2B data.
• Prepare GSTR-3B correctly.
• Track RCM payments.
• Review eligible ITC.
• Maintain supporting documentation.
• Monitor recurring RCM transactions.

For businesses with multiple expense categories or foreign vendors, this can reduce the risk of treating an RCM transaction as an ordinary purchase.

Final Thoughts

Reverse Charge Mechanism changes the normal GST payment process.

Instead of waiting for the supplier to collect and pay GST, the recipient may become responsible for identifying and paying the applicable tax.

The most important principle is:

Do not identify RCM only from the invoice. Identify it from the nature of the transaction and the applicable GST provisions.

A strong monthly RCM process should therefore follow:

Review transactions → Identify RCM → Verify applicable provision → Calculate tax → Report in GSTR-3B → Pay through permitted cash mechanism → Determine eligible ITC → Reconcile records.

Businesses should also periodically review changes in GST notifications because the categories and conditions applicable to reverse charge can change.
