Reverse Charge Mechanism (RCM) under GST

Normally, the supplier of goods or services pays the tax on supply. In the case of Reverse Charge, the recipient of goods or receiver becomes liable to pay the tax, i.e., the chargeability gets reversed.

There is a threshold limit for turnover aggregating to Rs 20 lakh (Rs 10 Lakh for north eastern states) for registration for normal taxpayers but under reverse charge, there is no such limit. The person has to be registered under GST irrespective of the aggregate limit. Therefore Mr. A is required to obtain GST Registration in Delhi.







When a Registered Dealer receives goods or services from an Unregistered Supplier

  3. In case of Inter-state purchases the recipient has to pay IGST. While for Intra-state purchases CGST and SGST has to be paid under RCM by the recipient.
  4. Example: Mr. A, a registered dealer under GST purchases goods worth Rs 50000/- from a unregistered supplier Mr. B. Hence in this case RCM would be applicable and Mr. A is applicable to pay GST to government under reverse charge.
