I have IGST payable of Rs.20k and Input credit in SGST- Rs.40k and CGST Rs.40k. How should I adjust IGST payable from input credit available in both of these?
After submitting GST3 B at the time of Set Off you will get the option to adjust CGST input against IGST Liability. After CGST is utilized you can utilize SGST for balance IGST Liability.
