Our client had made Deposit of Rs.1,20,000/- for Rent in April 2017, The deal was that our client doesn't have to pay monthly rent of Rs.10000/- PM for 12 month instead it was get adjusted against deposit on monthly basis. Accordingly, only JV passed to expense out rent on monthly basis. My question is do our client have to pay GST on reverse charges? Owner of Premises is unregistered.
