GST applies to under-construction properties in India but not completed ones. Rates vary based on affordability and property type. RWA fees above ₹7,500 are also GST applicable.
GST on flats is 5% for non-affordable housing and 1% for affordable housing, excluding Input Tax Credit. Under-construction flats have a 12% GST. Completed and resold flats are exempt. This impacts construction costs and simplifies the tax system.
