ITC for Builders and Developers
Residential developers (affordable and non-affordable):
- Cannot claim ITC on construction inputs (cement, steel, labour)
- The 1% and 5% rates are without ITC
Commercial developers:
- Can claim ITC on all construction inputs
- 18% GST on commercial construction with full ITC
Contractors (sub-contractors):
- Can claim ITC on materials and sub-contracted services
- Charge 18% GST on works contract services to main contractor
GST on Ready-to-Move-In Properties
Ready-to-move-in flats (with completion certificate): Exempt from GST
This is a significant benefit — buyers of completed properties pay no GST. Only under-construction properties attract GST.
GST on Joint Development Agreements (JDA)
When a landowner enters a JDA with a developer:
- Landowner: Transfers development rights to developer — taxable as supply of services
- Developer: Provides construction services to landowner — taxable at applicable rate
- GST on development rights: 18% (or applicable rate based on property type)
JDA transactions are complex — consult a CA for specific situations.

| Builder/developer (turnover > ₹40L) | Yes |
| Contractor (turnover > ₹20L for services) | Yes |
