When it comes to buying an apartment, one of the key factors affecting the total cost is the Goods and Services Tax (GST). GST is a comprehensive indirect tax that replaced multiple taxes like service tax, VAT, and excise duty, which were previously levied on the real estate sector. For residential properties, GST significantly affects the pricing structure, particularly for under-construction apartments. Generally, GST applies to under-construction apartments, which is essential for potential buyers to understand. The GST rate on real estate is 5% (without input tax credit or ITC). This tax is calculated on the property's sale price, which means that GST is added on top of the base price.
