Reverse Charge Mechanism (RCM) under GST — Complete Compliance
Complete RCM compliance: Section 9(3) notified supplies (GTA, legal, security, renting), Section 9(4), import of services, self-invoicing, payment vouchers and RCM ITC. Audit-proof your reverse charge. CA-led, pan-India.
Quick answer: Under reverse charge, the recipient — not the supplier — pays GST directly on notified supplies: goods transport agencies, advocate services, imports of services, director services and specified goods. RCM must be paid in cash and is claimable as ITC where eligible; unpaid RCM with interest is the most common departmental audit finding.
Reverse charge flips GST's default rule: the recipient pays the tax instead of the supplier. It exists for hard-to-tax supplier categories (goods transport agencies, advocates, unregistered persons, overseas suppliers) — and it is the most commonly missed liability in departmental audits, because nothing on the purchase invoice reminds you to pay. Unpaid RCM found in audit costs 18% interest and penalty exposure even though the ITC would have been fully claimable — a pure compliance own-goal.
Virtual Auditor builds RCM compliance that survives audit: an entity-specific applicability matrix, monthly expense-ledger scans, self-invoicing documentation, and defence where past RCM was missed.
Section 9(3) — Notified Supplies Where RCM Always Applies
| Supply | Supplier | Recipient liable | Rate / notes |
|---|---|---|---|
| Goods transport agency (GTA) | GTA not opting for forward charge | Registered factories, companies, firms, registered persons | 5% RCM (no ITC to GTA); GTA may opt for 5%/12% forward charge by annual declaration |
| Legal services | Advocate / firm of advocates | Any business entity with turnover above registration threshold | 18% |
| Security services (personnel) | Non-body-corporate supplier | Registered person | 18%; body-corporate suppliers charge forward |
| Sponsorship | Any person | Body corporate or partnership firm | 18% |
| Director services | Director (non-employee capacity) | The company | 18%; salary under employment contract is outside GST entirely |
| Renting of motor vehicle (with fuel) | Non-body-corporate charging 5% | Body corporate | 5% |
| Renting of residential dwelling | Any person | Registered person (subject to the proprietor personal-use carve-out) | 18% |
| Renting of commercial property | Unregistered landlord | Registered tenant | 18% — added from 10 Oct 2024; catches thousands of tenants with individual landlords |
| Goods: cashew (raw), bidi wrapper leaves, tobacco leaves, raw cotton, used vehicles/scrap sold by government, lottery | Agriculturist / government etc. | Registered buyer | Rates as notified |
| Metal scrap | Unregistered supplier | Registered buyer | RCM from 10 Oct 2024, plus 2% TDS on registered-supplier purchases |
Import of Services — the RCM Everyone Misses
Any service received from a supplier located outside India, for business, is taxable in your hands under RCM — regardless of value. The audit-season classics: Google/Meta advertising billed from Singapore/Ireland, SaaS subscriptions (AWS, Zoom, LinkedIn, Adobe), foreign consultants, licence fees and royalty to overseas parents, secondment arrangements (post the Supreme Court's Northern Operating Systems ruling, expatriate secondments are squarely targeted). Related-party imports are taxable even without consideration — Schedule I deems them supplies, valued under Rule 28.
Cash-flow note: RCM must be paid in cash — the electronic credit ledger cannot be used to discharge reverse-charge liability. The ITC comes back the same month (if eligible), but the cash-out is real, and for exempt-sector recipients (hospitals, schools, financial services) RCM is a permanent cost, not a wash.
Documentation — Where RCM Compliance Actually Fails
- Self-invoice (Section 31(3)(f)): mandatory for every RCM purchase from an unregistered supplier. Since the 2024 amendments, the self-invoice must be issued within 30 days of receipt of supply — and the ITC time limit runs from the self-invoice date, so a missing self-invoice can kill the credit.
- Payment voucher (Section 31(3)(g)): required at the time of payment to the supplier for RCM supplies.
- GSTR-1 Table 4B / GSTR-3B Table 3.1(d): RCM liability reported in 3.1(d), credit claimed in Table 4A(2)/(3). Reporting RCM in the wrong table is a red-flag mismatch.
- Invoice notation: registered RCM suppliers (advocates, GTAs) must state "tax payable on reverse charge" on their invoices — absence does not excuse the recipient.
Section 9(4) — Unregistered-Supplier RCM: Narrow but Alive
The original 2017 version of Section 9(4) — RCM on every purchase from unregistered suppliers — was suspended and then scrapped. What survives is targeted: promoters/builders must pay RCM on cement and on input shortfalls below the mandatory 80% registered-procurement threshold in real-estate projects, and specific notified goods (metal scrap from unregistered suppliers) now carry their own RCM entries. Businesses outside these categories owe nothing under 9(4) — but audit teams still raise it, and a crisp legal position note closes the query fast.
GTA — the Most Misunderstood RCM Entry
Three distinctions decide liability: (1) a GTA issues a consignment note; a mere truck owner without one is exempt transport of goods by road — no GST at all; (2) if the GTA has opted for forward charge (annual declaration by 31 March, now largely a standing option), it charges you 5% or 12% and RCM does not apply — collect the declaration copy from every transporter; (3) exemptions survive for small consignments (₹1,500/₹750 legacy limits) and specified goods (agricultural produce, milk, newspapers). Freight ledgers mixing GTA, non-GTA and courier payments are where audits find six-figure RCM gaps — our monthly scan classifies every freight entry.
Our RCM Compliance Programme
- Applicability matrix: your expense ledgers mapped against every 9(3) notification entry and the import-of-services test — a one-page yes/no/threshold chart your accounts team follows.
- Monthly ledger scan: freight, legal & professional, rent, security, director sitting fees, foreign remittances and subscriptions scanned for unpaid RCM before each GSTR-3B.
- Documentation kit: self-invoice and payment-voucher templates, numbering series, 30-day SOP.
- Back-period remediation: where RCM was missed, we quantify by year, pay with correct interest through DRC-03 before a notice makes it worse, and claim eligible ITC within the surviving time limits.
- Audit defence: RCM paras are among the most contested audit findings — our responses deploy revenue-neutrality arguments, the self-invoice date rule for ITC, and valuation defences for related-party imports (Rule 28 second proviso: invoice value accepted where full ITC is available).

Frequently Asked Questions
What is the reverse charge mechanism in GST?
Under RCM, the recipient of a supply — not the supplier — is liable to pay GST directly to the government. It applies to supplies notified under Section 9(3) (GTA, legal services, security services, sponsorship, director services, specified goods), to imports of services, and to specified purchases from unregistered suppliers under Section 9(4) (promoters) and newer entries like metal scrap and commercial rent from unregistered landlords. The recipient pays in cash and claims ITC if otherwise eligible.
Can RCM liability be paid using input tax credit?
No. Reverse-charge liability must be discharged in cash through the electronic cash ledger — the credit ledger cannot be used. The ITC on that RCM payment is then claimable in the same month's return if the underlying supply is eligible. This makes RCM cash-flow negative for one cycle even in the best case, and a permanent cost where your outputs are exempt.
Is GST payable under RCM on rent paid to an unregistered landlord?
For commercial property: yes — from 10 October 2024, a registered tenant paying rent to an unregistered landlord pays 18% GST under RCM. For residential dwellings rented to a registered person, RCM applies (with a carve-out where a proprietor rents purely for personal residence). Composition taxpayers renting commercial premises bear the RCM as a cost since they cannot claim ITC.
Do I need to pay RCM on Google Ads, AWS or foreign software subscriptions?
If the overseas supplier bills you from outside India, yes — import of services under Section 5(3) IGST Act, payable by you under RCM at 18%, with self-invoice documentation. (Some platforms bill through Indian entities and charge GST directly — check the GSTIN on the invoice.) This is among the most common audit findings for startups and agencies; the tax is usually revenue-neutral through ITC, but interest for late payment is not.
What is a self-invoice and when must I issue one?
When you receive RCM-liable supplies from an unregistered supplier, you must issue an invoice on your own supplier's behalf under Section 31(3)(f), within 30 days of receipt of the supply, plus a payment voucher when paying. The self-invoice is not paperwork trivia: after the 2024 clarifications, your ITC time limit runs from the self-invoice date — no self-invoice, no safe credit.
Is GST payable on remuneration to directors?
Salary to executive directors under an employment contract is outside GST (Schedule III). But sitting fees, commission to non-executive/independent directors, and professional fees billed by a director in a personal capacity attract 18% GST under RCM, payable by the company. Departmental audits routinely scan Form MGT and financial-statement disclosures for director payments — classification memos should be on file.
We discovered unpaid RCM for the last three years. What should we do?
Quantify by year, pay through DRC-03 with interest at 18% before any notice arrives — pre-notice payment means no penalty under Section 73(5). Claim the corresponding ITC where the time limit survives (for unregistered-supplier RCM, the clock runs from your self-invoice date, which helps). We handle the computation, DRC-03 mapping, self-invoice regularisation and the ITC claim as one exercise — turning a potential audit disaster into a manageable interest cost.
Does RCM apply to payments to freelancers and unregistered contractors?
Generally no — the blanket Section 9(4) RCM on unregistered purchases was scrapped; it survives only for promoters/builders (cement, 80% procurement shortfall) and specific notified goods like metal scrap. But check the 9(3) list first: if the freelancer is an advocate, a GTA, a security-services provider (non-body-corporate) or a sponsorship recipient, RCM applies because of the service category, not the registration status.
Is RCM applicable on ocean freight and import shipping?
The Supreme Court in Mohit Minerals (2022) struck down RCM on ocean freight in CIF imports as unconstitutional double taxation — the importer already pays IGST on the CIF value of goods. Refund claims for RCM paid on CIF ocean freight succeeded on this basis. FOB imports where you contract the freight separately need transaction-specific analysis. If you paid ocean-freight RCM historically, a recovery review is worth running.
How is RCM reported in GST returns?
Liability goes in Table 3.1(d) of GSTR-3B and is paid in cash; the corresponding credit is claimed in Table 4A(2) (import of services) or 4A(3) (inward supplies liable to reverse charge) of the same return. Registered RCM suppliers report those outward supplies in Table 4B of their GSTR-1, which flows to your GSTR-2B as RCM-flagged entries. Mismatches between 3.1(d) and the 2B RCM flags are now a standard scrutiny parameter — our monthly scan reconciles them before filing.
