No, there is no GST on ready-to-move flats that have received their Completion Certificate (CC) before the sale. The GST applies only to properties that are under construction. Since ready-to-move-in properties are considered completed projects, they are exempt from GST, making them financially appealing to buyers who wish to avoid the additional tax burden associated with new constructions. Buyers should ensure that the property they are interested in has the necessary completion and occupancy certifications to avoid any GST liabilities.
