GST on Sale of Buildings
An Interactive Guide to Understanding Tax Implications in India
The General Rule: Schedule III of the CGST Act, 2017
The Central Goods and Services Tax (CGST) Act specifies certain activities that are treated neither as a supply of goods nor a supply of services. As per Paragraph 5 of Schedule III of the Act, the "sale of land and, subject to clause (b) of paragraph 5 of Schedule II, sale of building" is excluded from the scope of "supply". This means if a completed building is sold, and the entire payment (consideration) is received after the issuance of a completion/occupancy certificate, no GST is applicable.

Analysis
Common Scenarios Explained
Situation: An individual purchases a ready-to-move-in apartment. The Occupancy Certificate (OC) has already been issued. The entire payment is made and the sale is registered after the OC date.
GST Implication: No GST is applicable.
Reason: This is a straightforward sale of a completed building where the entire consideration is received after the completion certificate. It falls squarely under Schedule III of the CGST Act and is not considered a supply.
Situation: A buyer books an under-construction flat and pays 20% of the value as an advance. The builder receives the OC a few months later. The remaining 80% is paid and the sale is registered after the OC is issued.
GST Implication: GST is applicable only on the 20% portion paid before the OC.
Reason: Any consideration received before the OC is for the supply of a service (construction service) as per Schedule II. The portion of consideration received after the OC is for the sale of a completed building, which is not a supply. Therefore, GST is levied only on the pre-OC payment.
Situation: A buyer purchases an under-construction property. The entire payment is made and the sale is registered before the builder applies for or receives the OC.
GST Implication: GST is applicable on the entire transaction value.
Reason: Since the entire consideration is received before the issuance of the completion certificate, the transaction is treated as a supply of construction services under Schedule II of the CGST Act. The exclusion under Schedule III does not apply.
