GST on under construction properties is applicable when purchasing a property that has not received its completion certificate at the time of sale. The applicable GST rate depends on the type of property, such as affordable or non affordable housing, and is generally included in the purchase cost. Understanding GST rates, exemptions, payment procedures, and financial implications helps homebuyers make informed decisions and avoid unexpected expenses during the home buying process.
Buying an under construction property offers advantages such as flexible payment plans, modern amenities, and the potential for price appreciation. However, unlike ready to move homes, under construction properties attract Goods and Services Tax (GST), making it important for buyers to understand how this tax affects the total purchase cost.
Whether you are purchasing your first home or investing in real estate, knowing the applicable GST rates, calculation methods, exemptions, refund rules, and documentation requirements can help you plan your finances better. This guide explains everything homebuyers should know about GST on under-construction properties in India.

| Particular | Amount |
|---|---|
| Property Price | ₹60,00,000 |
| Applicable GST Rate | As per applicable category |
| GST Payable | Based on the notified rate |
| Total Amount Payable | Property Price + GST |
The exact GST amount should always be verified from the builder’s demand letter and payment schedule.
