Nil rated Sales made to B2B

1. Nil rated u have to disclose in Table 8 as Nil rater inter state or intra state supply.

2. When u r marking both the type of sales in one invoice u have to disclose it under Table 4 as rate of tax zero and have to reverse the common ITC in proportion of the supply.

For purely nil rated invoices use table 8

Where in an invoice both taxable and nil rated supplies are made then use table 4

Thank you
If B2B Nil rated sales are shown in table 8 how could it be reflected to the buyer gstin?

And should the nil rated goods shown in table 4 along with taxable goods be seperated to nil rated sales row in Gstr 3b(where mismatch in values between Gstr1 and gstr3b occurs) or to be entered to taxable supplies row?
