Gst obligation in case of advance rent

Is the rental agreement for residential property or commercial one?

"Commercial"

As such the liability to pay GST over the rent arises as on appointed date....... for the month upto March, 2018 or upto the date of expiry of the agreement, whichever earlier.

Thankyou Mr. Rambhia, So I undersratnd that you suggest that GST will have to be collected and paid from 1st July till the expiry on Pro data Basis.

Can you please guide, As landlord issues invoice, Should he collect the Gst from tenant on monthly basis till the Contract Expires or a lumsum can also be collected and deposited?

Thanks
