GST Reverse Charge Mechanism (RCM): A Plain-English Guide

Reverse Charge Mechanism (RCM) flips the normal GST flow - instead of the seller paying tax, the buyer pays. Miss it on a single transaction and you owe back-tax, interest, and late fees. Get it right and your ITC stays clean.

This guide explains GST RCM in plain English - when it applies, who pays, how to claim ITC, and the mistakes that bring in notices.

What is Reverse Charge Mechanism in GST?

Under RCM, the recipient of goods or services pays GST directly to the government, instead of the supplier collecting and paying it. You then claim ITC on the same tax, provided conditions are met.

RCM is governed by Section 9(3) and 9(4) of the CGST Act.

Who pays tax under RCM?

• The recipient - regardless of the supplier's GST status
• The recipient must be registered under GST
• Tax is paid in cash - cannot be offset against existing ITC

Services covered under RCM

• Goods transport agency (GTA) services to registered persons
• Legal services by advocates
• Director's remuneration to companies
• Services by government or local authority
• Sponsorship services
• Import of services
• Renting of motor vehicles to corporate recipients

Benefits of understanding RCM

• Avoid tax recovery during audits
• Claim ITC correctly - no reversal risk
• Handle legal and GTA invoices cleanly
• Protect yourself when dealing with unregistered suppliers

Step-by-step: comply with RCM

1. Identify RCM-liable transaction - match against CBIC notifications
2. Self-invoice - generate an invoice under your own GSTIN
3. Pay tax in cash - via PMT-06 challan
4. Report in GSTR-3B - Table 3.1(d) + Table 4(A)(3)
5. Claim ITC in next cycle - subject to Section 16 conditions
6. Maintain records - invoice, payment voucher, challan

Documents to maintain

• Self-invoice under RCM
• Payment voucher
• PMT-06 challan
• GTA consignment note
• Advocate's bill of supply

Cost of missing RCM

• 18% annual interest on unpaid tax
• Penalty up to 100% of tax amount
• ITC denial on underlying input
• Audit escalation

Common mistakes under RCM

1. Offsetting RCM tax with existing ITC - must be paid in cash
2. Missing self-invoice - audit flag
3. Skipping GTA invoices - most common miss
4. Not tracking director sitting fees - falls under RCM
5. Forgetting foreign software imports - always RCM
