I am a composite taxpayer.I had made all my purchases for the quarter july-sep from registered taxpayer and paid gst at the time of purchase. By mistake I entered the details of inward supplies in 4B(B2B) tab of offline utility for gstr4 and submitted it. I had made the payment of tax equivalent to 1% of turnover but the liability of tax inward supplies is still pending.
Whether I have to pay tax again?Without settling the liability I cannot file gstr 4.What should I do?
