I am planning to buy an under construction flat in Kolkata. The carpet area of the flat is below 60 sq mt and the price is below 45 lacs. But the builder is asking for 5% GST saying that any flat is eligible for 1% GST only when all the flat is the project falls in that category. Since there are few flats above 60 sq mt he is demanding 5% GST. Kindly help me with official guidelines. Thanks in advance.
