In the given case, the supplier is unregistered and located in Kerala, the immovable property is situated in Tamil Nadu, and the recipient is a registered person in Tamil Nadu. The determination of the type of supply must be made by applying Section 12(3) of the Integrated Goods and Services Tax (IGST) Act, 2017.
Section 12(3) of the IGST Act clearly states that in case of services directly in relation to immovable property, including renting or leasing, the place of supply shall be the location of the immovable property, irrespective of the locations of the supplier or recipient. Accordingly, in this case, since the property is located in Tamil Nadu, the place of supply is Tamil Nadu.
Further, the recipient is also registered in Tamil Nadu. Hence, the location of the supplier (Kerala) is not relevant in determining the nature of supply when the supplier is unregistered and tax is payable under reverse charge. Since both the place of supply and the recipients location are in the same State (Tamil Nadu), the supply qualifies as an intra-State supply, and the applicable tax is CGST and SGST.
If the nature of service (such as renting of immovable property) falls under reverse charge as per Notification No. 13/2017 – Central Tax (Rate) dated 28.06.2017, the registered recipient in Tamil Nadu will be liable to pay CGST and SGST under reverse charge. There is no requirement for the unregistered supplier to obtain GST registration in this case.
