Hi,
Please get the clarity. It seems you are getting some confusion here.
GST is not at all applicable on Land & Buildings till date as they are covered in Stamp Duty of State.
Further, whatever GST you are talking about is applicable on construction activities carried out by builders and contractors in nature of services of construction and supply of building material as part of that construction services.
As such, applicability of GST on Land Owner who is willing to sell his Land & Buildings without any construction activities are not covered under GST.
If the land owner provides construction activity/ services to the potential buyers, only then GST@12% is applicable only on construction component not on value of Land & Buildings.
I hope now you are clear on this.
Regards,
