Input Tax Credit on Works Contract is one of the most confusing areas under GST. Many businesses claim GST on office renovation, interiors, painting, and construction but later face reversal with interest and penalty during audit.
The reason lies in Section 17(5)(c) and 17(5)(d) of the CGST Act, which block ITC on immovable property. Therefore, understanding these provisions is essential before claiming ITC.
Legal Background
GST allows credit of taxes paid on business expenses. However, Section 17(5) restricts credit on specific transactions even if used for business.
Two important clauses:
- Section 17(5)(c) – Works contract services
- Section 17(5)(d) – Construction on own account
Both apply mainly to office setup, renovation, factory building, interiors, and fit-outs.
What is Works Contract under GST
As per Section 2(119):
Works contract means construction, installation, repair, renovation or modification of immovable property involving goods and services.
Examples
- Office construction
- Interior designing with material
- Electrical wiring inside wall
- Plumbing and pipeline fitting
- Painting of building
If immovable property is involved, it becomes a works contract.
Section 17(5)(c) – ITC on Works Contract Services
ITC is not allowed when works contract services are used to construct an immovable property.
Exception
ITC is allowed only if the recipient is a works contractor and further supplies works contract service.
Example
| Situation | ITC |
|---|---|
| You hire contractor to build office | Not allowed |
| Builder hires sub-contractor | Allowed |
Section 17(5)(d) – Construction on Own Account
This clause blocks ITC on goods or services used for construction of immovable property even when used for business.
Meaning
Buying materials yourself also blocks ITC.
| Expense | ITC |
|---|---|
| Cement and tiles | Not allowed |
| Labour contractor | Not allowed |
| Office renovation | Not allowed |
Meaning of Construction
Construction includes reconstruction, renovation, alteration, and additions only when capitalized in books.
If expensed, ITC may be allowed depending on facts.

| Particular | 17(5)(c) | 17(5)(d) |
|---|---|---|
