What is Reverse Charge Mechanism and Why Does It Exist?
The Reverse Charge Mechanism (RCM) is a GST compliance framework under which the liability to pay GST is shifted from the supplier to the recipient of goods or services. In the normal GST framework, the supplier charges GST on the invoice and remits it to the government. Under RCM, the supplier issues an invoice without GST, and the recipient self-assesses the GST liability, issues a self-invoice, and deposits the GST directly with the government.nnRCM exists to address two enforcement challenges. First, certain categories of suppliers — individual advocates, goods transport agencies, and other small service providers — have large numbers of small clients spread across the country, making it administratively difficult to ensure every supplier registers for and complies with GST. By shifting the compliance obligation to the recipient — typically a larger, registered business — the government consolidates tax collection at fewer, more easily monitored points. Second, RCM captures tax on services imported from foreign suppliers who are outside India's GST jurisdiction — the Indian recipient is made responsible for paying GST on cross-border service imports.nnThe RCM provisions in India's GST law operate under two main sections. Section 9(3) of the CGST Act lists specific categories of goods and services on which RCM is mandatory regardless of whether the supplier is registered — these are notified by the government through periodic notifications. Section 9(4) creates RCM on supplies from unregistered persons to registered persons — though this provision has been limited in practice to specific categories notified by the CBIC rather than applying universally to all unregistered supplier transactions.
Complete RCM List Under Section 9(3) — Services and Goods
Section 9(3) of the CGST Act identifies specific categories where RCM applies regardless of the supplier's registration status. The key categories notified as of 2025 are as follows.nnLegal services by advocates — any registered business receiving legal services from an individual advocate or a firm of advocates must pay 18% GST under RCM. The advocate does not charge GST on their invoice. The business client self-invoices, pays 18% RCM GST to the government, and claims it as ITC in the same period making the net cost nil for registered businesses. Services by senior advocates to junior advocates and law firms are also under RCM from the law firm's side.nnGoods Transport Agency (GTA) services — when a business engages a GTA for transporting goods by road and the freight exceeds Rs.750 per single consignment or Rs.1,500 per single truck, the recipient must pay 5% GST under RCM (if GTA has not opted to pay GST themselves). GTAs can choose to charge GST themselves at 12% with ITC or 5% without ITC — if the GTA opts to charge GST, the recipient is not under RCM for that GTA. Direction to pay or not pay GST by the GTA depends on the GTA's registered option for the financial year.nnImport of services — any taxable service imported from a supplier located outside India for use in India attracts 18% GST under RCM regardless of whether the Indian recipient is GST-registered. This includes software subscriptions (Google Workspace, Microsoft 365, AWS, Salesforce), consulting fees to foreign firms, royalties to overseas IP holders, and management services from overseas holding companies. The Indian recipient must self-invoice and pay IGST at 18% under RCM for all such imported services.

RCM on Import of Services — Most Common Trigger for Businesses
Import of services is the most widely applicable and frequently encountered RCM scenario for modern businesses. Any business — registered or unregistered in India — that receives services from a supplier located outside India must pay IGST at the applicable rate under RCM. This obligation applies when: the supplier is located outside India, the place of supply is in India, and the service is received for use in India in the course of business.nnCommon imported services that trigger RCM: cloud computing and SaaS subscriptions (AWS, Google Cloud, Microsoft Azure, Salesforce, HubSpot, Slack, Zoom), software licences from foreign companies (Adobe Creative Cloud, Autodesk), digital marketing services from foreign agencies, consulting fees to foreign management consultants or advisors, legal advice from foreign law firms, royalties on intellectual property owned by overseas entities, and technical services from overseas parent companies to Indian subsidiaries.nnThe compliance process for RCM on imported services: step 1 — identify the foreign service invoice and determine the IGST rate applicable to that service type. Step 2 — create a self-invoice on or before the 20th of the month following the month of receipt of services or payment, whichever is earlier. Step 3 — declare the RCM liability in GSTR-3B Table 3.1(d). Step 4 — pay the IGST through the Electronic Cash Ledger (ITC cannot be used to pay RCM — cash payment is mandatory). Step 5 — claim the same IGST as ITC in Table 4 of GSTR-3B in the same or subsequent period. For most businesses making taxable supplies, the ITC offsets the cash payment making the net tax impact nil.
RCM Compliance — Self-Invoice, Payment and ITC Claim
RCM compliance involves a distinct set of procedural steps that differ from regular forward charge GST. When a business receives a supply attracting RCM, the supplier does not issue a GST invoice with tax — they issue an invoice showing their fees without any GST. The recipient must create a self-invoice internally to document the RCM liability.nnThe self-invoice must be issued by the recipient on or before the 20th of the month following the month in which the supply was received or payment was made to the supplier, whichever is earlier. The self-invoice should contain: the recipient's own GSTIN and address as the supplier details, the original supplier's details, the nature of supply, the value, and the IGST/CGST/SGST computed on that value.nnA critical procedural point in RCM: the GST on RCM supplies cannot be paid using ITC from the Electronic Credit Ledger. It must be paid in cash through the Electronic Cash Ledger. This is a specific restriction under Section 49(4) of the CGST Act. After making the cash payment, the same amount can be claimed as ITC in Table 4(A)(3) of GSTR-3B in the same or subsequent return period — so the cash is effectively only a timing cost. For businesses with large imported service invoices, this creates a temporary cash flow requirement that must be managed in monthly GST working.
Section 9(4) RCM — Purchases from Unregistered Suppliers
Section 9(4) of the CGST Act originally required registered businesses to pay RCM on all purchases from unregistered suppliers — a provision that proved practically unworkable given the vast unregistered sector in India. This blanket application was suspended and then replaced with a targeted approach: RCM under Section 9(4) now applies only to specific categories of goods and services notified by the CBIC, not to all unregistered supplier purchases.nnIn 2025, the notified categories under Section 9(4) include: raw cotton purchased by registered entities from unregistered farmers (RCM at 5%), lottery tickets from distributors who are unregistered, and a few other specifically notified categories. For most routine business purchases from unregistered vendors — raw materials from small suppliers, office supplies from local shops, or maintenance services from unregistered contractors — there is no RCM obligation under Section 9(4). Businesses should verify the current notification list for Section 9(4) categories as they are subject to change through CBIC notifications.nnThe residential rent RCM introduced from 18 July 2022 is technically a Section 9(3) notification rather than Section 9(4) — it applies specifically when a GST-registered person rents residential property for business use. The property owner (landlord) is treated as a supplier of rental services without GST, and the registered tenant is the recipient obligated to pay 18% RCM GST. This important provision continues in full force for FY 2025-26 and affects a significant number of registered businesses and professionals operating from rented residential spaces.
