I am a metal scrap trader i have a doubt that if i purchase metals from local scrap supplier at 30.5 without gst (consider the market price is 28 plus gst ) and i sale it with gst at The price of 26.5 plus gst can i consider the payment i had given to the local seller as 25.85 plus gst by considering in rcm method and pay the excess rs 0.12 to gst portal offseting it or i need to pay rs 4.65 to gst portal to claim itc and reverse it
