When selling land, it's important to understand its GST classification. According to the CGST Act 2017, the sale of land is considered neither a supply of goods nor a supply of services, meaning GST does not apply. If you are registered for GST, you should declare the sale of land as 'Non-GST' in your GSTR1 return, rather than 'Nil' rated.
As per Para 5 of SCHEDULE III of the CGST Act 2017, Sale of "LAND" is neither treated as Supply of Goods or Supply of Services. Hence, GST is not applicable on sale of land.
