Construction contracts that bundle materials and labour are treated as works contracts under GST. A works contract is a composite supply of services, not a supply of goods. This classification has significant implications for rate, valuation and input tax credit.
What Is a Works Contract?
Section 2(119) of the CGST Act defines works contract as a contract for building, construction, fabrication, completion, erection, installation, fitting out, improvement, modification, repair, maintenance, renovation, alteration or commissioning of any immovable property where transfer of property in goods (whether as goods or in some other form) is involved in the execution of such contract.
Key elements:
- There must be a contract.
- The contract must involve immovable property.
- There must be transfer of property in goods.
- The activities listed must be covered.
Examples:
- Construction of a building
- Interior fit-out of an office
- Renovation of a house
- Installation of a lift that becomes part of a building
- Laying of pipelines
- Painting and waterproofing of buildings
Works Contract Is a Service
Schedule II, paragraph 6(a) provides that a works contract shall be treated as a supply of services. Therefore, even if the contractor supplies goods like cement, steel, paint or electrical items, the entire contract is taxed as a service, not as separate goods.
GST Rates on Works Contract
The GST rate on works contract services depends on the nature of the project:
- Residential premises under affordable housing: 1.5% CGST + 1.5% SGST = 3% without ITC, or 5% with ITC under certain schemes? The effective rates are often 5% without ITC under specific notifications.
- Other residential and commercial construction: 12% (6% CGST + 6% SGST) with ITC, or 5% without ITC for certain residential projects under old notification.
- Works contracts for government authorities: 12% with ITC.
- Works contracts for roads, bridges, railways, etc.: 12% with ITC.
- Composite supply of works contract in general: 18% for many commercial and industrial works contracts.
The exact rate depends on the notification and the specific project. Builders often opt for 5% without ITC for residential projects under Notification No. 11/2017-CT(R).
ITC on Works Contract
Input tax credit on works contract services is allowed only if the works contract service is used for furtherance of business and is not blocked under Section 17(5)(c). That section blocks ITC on works contract services for construction of an immovable property (other than plant and machinery) except where it is an input service for further supply of works contract.
This means:
- A contractor providing works contract services to a customer can claim ITC on inputs and input services used.
- A customer who is not in construction business and gets an office built cannot claim ITC on the works contract service.
Valuation
The value of a works contract is the entire contract value, including all materials, labour, design, supervision, and profit. There is no separate taxation of goods and services within the works contract.
Practical Example
A contractor agrees to renovate a client's office for Rs 50,00,000, including supply of tiles, paint, electrical fittings and labour. This is a works contract. If the applicable rate is 18%, the contractor charges GST at 18% on Rs 50,00,000 and pays output tax. The contractor can claim ITC on materials and services used.
Distinction from Composite Supply of Goods
If a contractor only supplies goods and does not undertake installation or construction of immovable property, the supply may be a composite supply of goods. For example, supply of a movable AC unit with simple installation is not a works contract.
Common Mistakes
- Treating works contract as supply of goods and charging GST only on materials.
- Not applying the correct rate for affordable housing.
- Claiming ITC when blocked.
- Splitting contracts to avoid works contract classification.
