Understanding Works Contract

A works contract is issued to carry out the construction, installation, erection, repair, renovation, maintenance, or alteration of any movable or immovable property, including the sale of goods. This contract involves providing a taxable service and selling a taxable good. Consequently, service tax is applicable on the service portion of the works contract.

What Constitutes a Works Contract?

A works contract involves the transfer of property in goods, where tax on the sale of goods is leviable. It encompasses executing the following services:

  • Erection, commissioning, or installation of plant, machinery, equipment, structures, and electronic devices. This includes plumbing, drain laying, and other installations for fluid transport, heating, ventilation, air-conditioning, as well as related pipework, ductwork, and sheet metal work.
  • Construction of new buildings, civil structures, pipelines, or conduits, primarily for commercial or industrial purposes. Learn more about the Karnataka RERA registration for projects associated with construction.
  • Development of new residential complexes.
  • Completion, finishing services, repair, alteration, renovation, or restoration services.
  • Turnkey projects including engineering, procurement, and construction or commissioning (EPC) projects. For projects involving agricultural marketing, see the Extension of New Agriculture Marketing Infrastructure Scheme.

Applicability of VAT

VAT or sales tax is levied on the transfer of property in goods involved in executing a works contract. The taxable service applies only to the services part of the contract execution. For more on property laws, explore Laws of Property Inheritance in India.

Works Contract Composition Scheme

As mentioned earlier, service tax is applicable solely to the service segment of the contract value. The taxable service value is typically determined according to the records maintained by the business. Alternatively, businesses can opt for a composition scheme, requiring them to pay 4% of the total contract value as service tax. However, businesses choosing the composition scheme cannot avail CENVAT credit on capital goods, inputs, and input services needed for the contract.

Calculating Taxable Service

In a works contract, the gross amount charged is inclusive of VAT or sales tax. The taxable service value for service tax is computed as follows:

[Gross amount charged - (Value of transfer of property in goods involved in the execution of the works contract and VAT or sales tax paid, if any, on the said transfer)].

Excise Duty Credit

For works contract services, the taxable value excludes the value related to transferring property in goods, which is leviable under VAT or sales tax. Therefore, the service provider cannot credit excise duty on such goods. To understand more about reverse charge mechanisms in GST, see our GST Reverse Charge Calculator.
