This means every civil contract, whether for a residential building, commercial complex, or government infrastructure project, is taxed as a composite supply of service, and the contractor must be GST-registered to raise a valid tax invoice, claim input tax credit on materials, and participate in e-tender portals like GeM and CPWD.
