Gst on flat purchase

Hello Satyendra.

As per GST Act, The GST rate payable on construction services is 18%. However, the effective rate paid on property transaction would be 12%, as GST at the rate of 18% is levied only on 2/3rd of the amount for the property; 1/3rd of the amount is deemed as value of land or undivided share of land supplied to the buyer and is not taxable under GST. However if you have purchased property under Credit linked Subsidy Scheme  then effective rate of GST is 8%

As builder is asking for Rs.128000 on purchase of flat  of Rs.16,65,000 which will come roughly around 8%. This seems to be correct as under CLSS scheme.
