This is a case of March 2020. An Assessee has Filed NIL GST Return even though there was a sale in March 2020 and Tax Payable was RS. 26000.
Now, he wants to pay the Tax because the Purchaser has withheld the payment. How this unpaid GST can be paid now. Please advise how to resolve the issue. (The purchaser is not willing to deduct the amount of mismatch from the payment due).
