Frequently asked questions

What is ITC utilisation order under GST?

Under Sec. 49A and 49B, IGST credit is applied first to IGST, then CGST, then SGST. CGST credit offsets CGST and then IGST. SGST credit offsets SGST and then IGST. Cross-utilisation between CGST and SGST is not allowed.

Can ITC offset reverse charge GST?

No. GST payable under the reverse charge mechanism must be paid in cash and cannot be offset against ITC in the same period.

What does this calculator optimise?

It applies ITC in the legally correct priority order to minimise the total cash outflow for IGST, CGST, and SGST after using available credit.
