Supply as Taxable Event under GST: taxes attach to supply including free, deemed, and agent-mediated transactions.
Tax liability under GST arises on the supply of goods or services, an inclusive concept covering sale, transfer, barter, license, rental, lease or disposal, whether for consideration or not; deemed supplies in Schedule I (permanent disposal of business assets, private use of business assets, services used privately, assets retained after deregistration, and inter taxable person transfers) attract tax; Section 3(2) and Schedule II classify transfers as supply of goods or services; agency and aggregator provisions deem principal-agent and aggregator transactions to be supplies while an agent who neither receives nor supplies on behalf of a principal is not liable.
