Meaning and Need for Goods and Services Tax

1. Meaning and Need for Goods and Services Tax

Goods and Services Tax (GST) is a single, destination-based, multi-stage indirect tax levied on the supply of goods and services, collected at every stage of value addition, with credit allowed for the tax already paid at the previous stage. GST was introduced in India through the Constitution (One Hundred and First Amendment) Act, 2016, and came into effect from 1 July 2017, replacing a large number of separate Central and State indirect taxes with one unified tax on the supply of goods and services across the country.

Why India needed GST — the problems with the earlier system. Before GST, a single transaction could attract several different indirect taxes levied separately by the Centre and the States — Central Excise Duty on manufacture, Service Tax on services, and, at the State level, Value Added Tax (VAT)/Sales Tax, Central Sales Tax on inter-state sale, Entry Tax or Octroi on goods entering a state or city, Luxury Tax, and Entertainment Tax, among others. This fragmented structure created several genuine problems:

1. Cascading effect ("tax on tax") — because credit for taxes paid at one stage often could not be fully claimed against a different tax levied at the next stage (a manufacturer's Excise Duty, for instance, was not creditable against a later State VAT), tax paid earlier in the chain itself became part of the price on which the next tax was calculated, inflating the final price to the consumer well beyond the sum of the individual tax rates.
2. Multiplicity of taxes and compliance burden — a business could be liable to register for, calculate, and separately file returns under several different Central and State taxes at once, each with its own rules, rates, and forms.
3. Barriers to inter-state trade — Entry Tax and Octroi, and the documentation and check-posts used to enforce them, slowed the movement of goods across state borders, including Andhra Pradesh's own trade with neighbouring states such as Telangana, adding real cost and delay without adding any value to the goods themselves.
4. Tax rates and rules varying by state — differing VAT rates and rules across states distorted business decisions on where to locate and how to price, instead of those decisions being driven purely by genuine economic efficiency.

GST's design directly answers each of these problems, chiefly through two features: it is levied on the SUPPLY of goods and services (a single, wider taxable event, replacing the separate events of "manufacture," "sale," and "provision of service" that triggered different taxes earlier), and it allows Input Tax Credit across the whole chain (covered in Section 3), which removes the cascading effect by letting a business set off the GST it has already paid on its own purchases against the GST it collects on its own sales. This is why GST is often summarised, in the words widely used to describe its introduction, as "One Nation, One Tax, One Market."

GST is:

• Destination-based, not origin-based — the tax revenue accrues to the State where the goods or services are actually consumed, not the State where they are produced or from which they are despatched.
• A multi-stage tax — collected at every point in the supply chain, from the manufacturer, to the wholesaler, to the retailer, wherever value is added. …
