This discussion clarifies the process of GST setoff, particularly for IGST, CGST, and SGST. It explains the two-step procedure: first, intra-head setoff (CGST liability against CGST input, and SGST liability against SGST input), and then inter-head setoff using IGST input for CGST liability. The example provided demonstrates how to calculate the remaining tax payable after utilising available input tax credits.
First IGST input of Rs 50 has to be fully utilized. CGST output of Rs 90 will be first set off with IGST input of Rs 50. Then balance CGST output of Rs 40 will be set off with CGST input of Rs 150. Now c/f under CGST is Rs 40/-.
SGST output is to be set off with SGST input. Balance c/f in SGST is Rs 60/-
