Works Contract

In layman’s term, a works contract is a contract of service which may also involve the supply of goods in the execution of the contract. Further, a contract of work may relate to both immovable and immovable property, in a general sense.

Works Contract Under GST

Works Contract under GST laws are put under a restriction i.e., they involve works only in relation to “Immovable Property”. In other words, these contracts under GST do not include works in relation to movable property.

Definition Of Works Contract

The Works Contract has been defined in Section 2(119) of the CGST Act, 2017 as
“works contract” means a contract for building, construction, fabrication, completion, erection, installation, fitting out, improvement, modification, repair, maintenance, renovation, alteration or commissioning of any immovable property wherein transfer of property in goods (whether as goods or in some other form) is involved in the execution of such contract.”

As per CGST Act, works contracts are a supply of services under GST.

Input Tax Credit On Works Contract

The Input Tax Credit on work contract under GST is available when the services are in use for further supply of services. In addition to this, ITC on such contract is available when services are in use for the construction of plant & machinery.

For instance, a building developer may engage the services of a sub-contractor for a certain portion of the whole work. The sub-contractor will charge GST in the tax invoice raised on the main contractor. The main contractor will be able to take ITC on the tax invoice raised by his subcontractor, as his output is works contracts service. However, if the main contractor provides this contract service (other than for plant and machinery) to a company say in the Software business, the ITC of GST paid on the invoice raised by the works contractor will not be available to the Software Company.

In other words, the ITC on these contracts is not available where services:

  • are not in use for further supply of services
  • are in use for construction of immovable property other than plant & machinery
Place Of Supply

As stated above, works contract under GST necessarily involves immovable property. In view of the same the place of supply, where both the supplier and recipient are located in India – the place of supply would be where the immovable property is located. On the contrary, in case the immovable property is located outside India, and the supplier as well as recipient both are located in India, the place of supply would be the location of recipient. Furthermore, in cases where either the supplier or the recipient are located outside India, the place of supply shall be the place where the immovable property is located or intended to be located.

Maintenance of Records

As per CGST Rules, 2017, every registered person executing work contracts shall keep separate accounts for work contract showing:

  • The names and addresses of the persons on whose behalf the work contract is under execution
  • The description, value and quantity (wherever applicable) of goods or services received for such execution
  • The description, value and quantity (wherever applicable) of goods or services utilized in the execution
  • The details of payment received in respect of each works contract
  • Names and addresses of suppliers from whom he received goods or services.
