This book serves as a comprehensive guide on the GST implications of Joint Development Agreements (JDAs) in India's real estate sector. It introduces a structured T1–T4 framework covering every taxable transaction within a JDA—from the supply of transferable development rights (TDRs) and construction services between landowners and developers to the sale of flats, units, or plots to end customers—with each transaction analysed across three dimensions: taxability, value & rate, and time of supply. The book offers separate chapter-wise treatment for residential, commercial, and plotted development projects, supported by practical case studies, worked-out illustrations, input tax credit analyses, and references to landmark judicial decisions, Board Circulars, and key Notifications. It traces the complete legislative evolution from the pre-GST Service Tax regime through the GST rollout on 1st July 2017 and the rate restructuring effective from 1st April 2019, addressing transitional issues for legacy JDAs.
