Goods and Services Taxes is a comprehensive academic text that provides an in-depth understanding of India’s indirect taxation framework with a strong focus on the Goods and Services Tax (GST). The book systematically traces the evolution of GST, its constitutional foundations, and the role of the GST Council, while explaining core concepts such as levy, collection, rates, and compliance mechanisms. It offers detailed coverage of input tax credit, reverse charge mechanism, e-way bills, registration, returns, assessments, interest, penalties, and audits. Advanced topics including composite and mixed supplies, place, time and value of supply, exemptions, and recent GST Reforms 2.0 (2025) are thoroughly discussed. The text also integrates the Customs Act, 1962 and the Foreign Trade Policy 2023, linking domestic taxation with international trade. Written in a clear, structured, and student-friendly manner, the book is well aligned with university syllabi and is equally valuable for students, educators, tax practitioners, and commerce professionals.
