This discussion explores whether a landlord needs separate GST registration in a state where their immovable property is located, even if they are registered elsewhere. While the place of supply is where the property is, the location of the supplier is key. If the landlord doesn't have a 'place of business' or 'fixed establishment' in the property's state, they can typically register in their usual place of residence and charge IGST on interstate supplies.
Better to refer Sec 12(3) of IGST act... In case You think some of the other view and charge IGST without take registration then You face problem under GST...
