I am sorry ti say there are very wrong answers on this forum. Shifa, You can get ITC credit if RCM in same month. If you have forgot to demand in July you can do it in Aug GSTR3b. Ankit, Amount will be reflected in credit ledger as ITC. Also ITC on amount above 5000 IS also eligible except for few items that food, radio taxi etc
Baldev, If regd. GTA has charged GST then it has to be shown on invoice. then no need to pay on RCM basis. IF GST is not shown on invoice then you have to pay on RCM basis and take credit later
