1) Fix Payment Method challan is generated based on preceding month's payment from cash ledger. So those who haven't paid tax from cash ledger in preceding Quarter can't avail this method? Will they need to pay Their GST liability in full using self assessment method?

2) Said GST Liability is arising due to vendor's default in furnishing IFF before 13th and I didn't pay tax as I'm anticipating that vendor will upload the bill next month. What about interest on late payment? Will I need to pay interest if he uploads the invoice in next month's IFF?
