A supplier was registered in Goa in old tax regime as service tax payer.

Now the supplier has taken GST registration in Maharashtra and supplying services to Goa by putting IGST.

Can he do business from Maharashtra to Goa by putting IGST, although he mentioned two address in invoice of IGST one of Goa one of Maharashtra, and he was registered in service tax payer in Goa
