Concept and Historical Background of GST
A note on currency (read this first)
This chapter covers the CONCEPT, structure and objectives of GST — no numerical GST-computation problems are set here, matching the syllabus's own scope for this unit. Where any rate or figure is mentioned for illustration, it is flagged as "illustrative, current as of this writing" rather than as a fixed syllabus fact — GST rate slabs are revised from time to time by the GST Council, and a student should always confirm the rate actually in force for the year being examined.
What is GST?
Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based indirect tax levied on the supply of goods and services, right from the manufacturer/service-provider up to the final consumer. "Multi-stage" means GST is levied at every stage of the supply chain — production, wholesale, retail — but through the mechanism of input tax credit, tax paid at an earlier stage is set off against tax payable at the next stage, so the FINAL burden falls only once, on the end consumer, and never cascades stage upon stage. "Destination-based" means the tax revenue accrues to the State where the goods/services are actually CONSUMED, not the State where they are produced — a sharp departure from several pre-GST taxes that were origin-based.
Historical background
GST replaced a fragmented structure of central and state indirect taxes with a single, unified tax on the supply of goods and services across India. Its key milestones:
- The idea of a single, nationwide Goods and Services Tax was under discussion in India for over a decade before it was actually implemented, requiring both a Constitutional amendment (since taxation powers on goods and services were then divided between the Centre and the States) and extensive Centre-State negotiation on revenue-sharing.
- The Constitution (One Hundred and First Amendment) Act, 2016 amended the Constitution to give Parliament and every State Legislature concurrent power to make laws on the supply of goods and services, and established the GST Council (Article 279A) as the constitutional body to recommend GST rates, exemptions, and procedures.
- GST was rolled out across India with effect from 1 July 2017, under the widely-used slogan "One Nation, One Tax, One Market."
WBCHSE's Costing and Taxation syllabus draws GST's concept and background from the same central GST law that CBSE/NCERT-aligned Business Studies and Economics courses across India also teach — GST is a single, uniform national tax, so its concept does not vary from board to board.
A comprehensive, multi-stage, destination-based indirect tax on the supply of goods and services, levied at every stage of the supply chain with input tax credit ensuring the final burden falls only once, on the end consumer.
A tax whose revenue accrues to the State where the goods/services are actually consumed, rather than the State where they are produced — the principle GST is built on.
