Hi,
Hope you are doing well !!
Yes, landowner is liable to pay 12% of his share of constructed area's value as GST.
When a developer enters into a development agreement with a Landowner, GST would become payable by the Landowner when the developer transfers possession or the rights in the constructed complex, building or civil structure, to the Landowner by entering into a conveyance deed or allotment letter.
Hence, when the Landowner receives a constructed property from the Developer in exchange for providing land, the Landowner would become liable for payment of GST. The GST rate applicable on such a transaction would be 18%.
The actual GST rate for under construction flats, properties or commercial properties is 18%. However, 1/3 of 18% is deemed as the value of land or undivided share of land supplied to the buyer of the property. So effectively rate will be 12% with full ITC.
It should be calculated on fair market value of land.
Thanks & Regards,
