As per circular for the time being the restaurants will show it as nil rated supply in table 8 of GSTR-1 and correspondingly in 3.1(c) of GSTR-3B. In my opinion even that is not required but follow the circular as it does not have tax implications and will be helpful in reconciliations with Income Tax return at year end
Sir that notification has put Ecom in taxable catagory. but doesn't say reg restaurants need not pay on sale thru Ecom operators. I am confused. even sec 9(5) talks about liability of Ecom only
