GST on rental of commercial property

no....you cannot charge igst....as in case of immovable property place of supply is where the property located....in your case it is Mumbai....you are also registered in Mumbai...so cgst and sgst will be chargeable.....

and what do you mean by centralised registration? there is no centralised registration. in gst....do you mean isd??

Thanks for the reply. But what is isd?

isd means Input Service Distributer...isd is like a centralised office which receives all the bills related to services provided by all the branches and distribute the credit to all the branches as provided by law

Earlier in service tax ISD were allowed to take centralised registration.....but in gst there is no concept of centralised registration..... isd and each branch has to register separately.

Dear Team,
we are having GST registrations in all the states and having ISD registration in tamilnadu along with TN registration, now our employees going for event with respect to market strategies in Hyderabad and those input services are common to us ,hence we need to distribute the input
shall we share our GST ISD number to event person and will distribute the Hyderabad Sgst and cgst to all the locations.
