CA Inter Students' Guide to GST & Customs Law

Students' Guide to GST & Customs Law is a comprehensive, student-oriented, and application-driven textbook that presents the Goods and Services Tax (GST) and Customs Law as an integrated, fully operational indirect tax system in India. The book reflects the settled and jurisprudentially mature phase of GST alongside the continuously evolving customs law framework governing cross-border trade. It explains GST not merely as a statutory framework, but as a functional economic and compliance system, focusing on how levy, classification, valuation, place of supply, time of supply, exemptions, input tax credit, and compliance provisions operate in practice. Parallelly, Customs Law is treated as an equally important pillar of indirect taxation, with structured and detailed coverage of customs duties, valuation rules, clearance procedures, baggage provisions, and exemptions. The central objective of this work is to eliminate learning fragmentation. It is editorially designed to minimise the need to consult multiple textbooks, bare acts, and problem manuals by offering a single, integrated learning resource that systematically moves from statutory concepts to analytical reasoning and practical application. Written on a teach-yourself methodology, the book functions simultaneously as a classroom textbook, a self-study guide, and an examination companion.

This book caters to multiple audiences, as listed below:

• Students of CA, CS, CMA, & Other Professional Courses where GST and Customs form core or allied subjects
• Undergraduate & Postgraduate Students of Commerce, Management, and Law studying indirect taxation
• Faculty Members & Academic Institutions seeking a structured, paragraph-wise, illustration-driven teaching text
• Learners Preparing for Examinations that emphasise problem-solving, valuation, and application of law, rather than rote learning
• Early-career Professionals seeking a consolidated reference on GST and fundamental customs law
