Hi,
The rule of availing and set off of credit of IGST is that the Tax Credit of IGST can be used for the payment of IGST. If any credit is left then it can be used for payment of CGST first and then for the payment of SGST/UTGST.
So, if you have no IGST and CGST payable, you can indeed use the IGST for payment of SGST.
