Is GST Applicable on Under Construction Property?
Yes. GST is applicable when you purchase a flat, apartment, or commercial space that is still under construction. The GST is calculated on the sale value of the property (excluding land cost).
Once the building is complete and the builder obtains a Completion Certificate (CC) or Occupancy Certificate (OC), no GST is charged on the sale.

GST on Apartments Under Construction
All types of apartments—whether luxury or budget—are covered under GST when sold before completion. The gst on apartments under construction is:
- 5% for standard units
- 1% for affordable units
The builder cannot claim Input Tax Credit (ITC) under the new GST regime (post-April 2019). So, all project-related GST costs are absorbed in the base selling price.
Old GST on Commercial Property Under Construction
(Old GST Rates – Applicable Until 21st September)
For commercial properties like offices, shops, or retail units under construction, the applicable GST rate is:
- 12% with Input Tax Credit
This applies to:
- Commercial buildings
- Business parks
- Co-working spaces
- Under construction malls or showrooms
So, the gst on commercial property under construction is higher, but allows ITC claims, which can benefit businesses in the long run.
GST on Under Construction Buildings (Mixed Projects)
Builders working on mixed-use buildings—for example, residential towers with retail shops on the ground floor—must apply different GST rates:
- Residential portion: 1% or 5% (based on classification)
- Commercial portion: 12% with ITC
Correct documentation and bifurcation in invoicing are essential to ensure GST is applied properly to each unit.
