Works Contract Under GST — Key Provisions
Definition Under GST
Works contract is defined under Section 2(119) of CGST Act as a contract for building, construction, fabrication, erection, installation, repair, maintenance, or commissioning of immovable property where transfer of property in goods is involved.
Deemed Supply of Service
Under Schedule II Para 6(a), works contract involving immovable property is treated as supply of service. This is a composite supply where goods and services are naturally bundled.
