Reverse Charge Mechanism (RCM) in GST India: Accounting and Compliance Guide
Reverse Charge Mechanism (RCM) shifts GST payment responsibility from supplier to buyer in specified cases.
When RCM Applies
RCM applicability depends on transaction type, supplier category, and notified rules. Businesses should not rely on assumptions or manual flags alone.
Accounting Treatment Under RCM
A robust accounting flow usually captures:
- GST liability under reverse charge
- corresponding eligible ITC (where applicable)
- clear document linkage for audit trail
Common RCM Mistakes
- treating normal taxable invoices as RCM
- claiming ITC before legal eligibility
- missing GSTIN/supply details in purchase records
- inconsistent posting between tax and ledger layers
Practical Compliance Controls
- enforce RCM classification checks at document creation
- keep supplier compliance metadata updated
- lock posted tax flags against casual edits
Final Takeaway
RCM is a high-risk GST area because structural mistakes can affect both tax liability and ITC.
Businesses need strong validation and posting controls, not only manual review.
