Understanding GST Basics in India

Goods and Services Tax (GST) is a comprehensive indirect tax introduced in India in 2017 to unify various indirect taxes like VAT, excise duty, and service tax under a single system. It is a multi-stage, destination-based tax applied on value addition at each step of the supply chain. This reform brought significant transparency and streamlined the tax structure across states. This article provides the fundamental concepts constituting the GST system and framework, aimed at helping businesses stay compliant.

Purpose of Goods and Services Tax (GST) System

The purpose of the Goods and Services Tax (GST) system is to create a unified and transparent tax structure across India by subsuming multiple indirect taxes such as VAT, excise duty, and service tax into a single tax regime. GST aims to eliminate the cascading effect of taxes, ensure a seamless flow of input tax credit, and promote ease of doing business by standardizing tax rates and compliance procedures nationwide. By treating the entire country as a single market, GST enhances efficiency in tax collection, reduces tax evasion, and fosters economic integration.

Who Needs to Register Under GST?

GST registration is mandatory for:

  • Individuals or businesses supplying goods/services exceeding ?20 lakh annually (?10 lakh for special category states)
  • Persons making inter-state taxable supplies
  • E-commerce operators and those supplying through such platforms
  • Aggregators offering branded services
  • Casual and non-resident taxable persons
  • Persons liable for TDS/TCS
  • Input Service Distributors (ISD)
  • Agents acting on behalf of taxable suppliers
  • Providers of online database access or retrieval services (from outside India to unregistered persons in India)
  • Entities liable to pay under the Reverse Charge Mechanism

GST Framework under the Law

GST replaced several indirect taxes like VAT, CST, excise, and service tax with a unified tax structure. There are two major GST categories in India:

  • Intra-state supplies: Subject to CGST (Central GST) and SGST (State GST)
  • Inter-state supplies: Subject to IGST (Integrated GST)

Imports are treated as inter-state supplies and attract IGST, while exports and supplies to SEZs are zero-rated.

Intra-State Supplies: CGST and SGST

When goods or services are supplied within a single state, both CGST and SGST are levied. The tax collected is shared equally between the Centre and the State where the transaction takes place. For example, a sale within Maharashtra would attract both CGST and SGST, each typically at half the applicable GST rate.

Inter-State Supplies: IGST

For transactions that cross state borders, IGST is imposed. This single tax is collected by the Central Government and later apportioned between the Centre and the destination state. IGST simplifies inter-state trade by eliminating the need for multiple tax payments and ensures that the tax revenue reaches the state where the goods or services are ultimately consumed.

Treatment of Imports and Exports

  • Imports: Imports of goods and services are treated as inter-state supplies under GST law and attract IGST at the applicable rate. Importers must also pay Basic Customs Duty (BCD) in addition to IGST. The IGST paid on imports is eligible for input tax credit, while customs duty remains a cost.
  • Exports: Exports and supplies to Special Economic Zones (SEZs) are zero-rated. This means no GST is charged on such supplies, and exporters can claim a refund of input tax credit or IGST paid, ensuring Indian exports remain competitive globally.

What are the GST Tax Rates in India?

India’s Goods and Services Tax (GST) regime features a multi-tiered tax structure designed to balance affordability for consumers with revenue needs for the government. The GST Council regularly reviews these rates, and as of 2025, the following slabs are in effect:

0% GST Slab (Nil Rated/Zero Rated)

  • Exports: All exports of goods or services and supplies to Special Economic Zone (SEZ) developers or units are classified as zero-rated supplies. This means no GST is charged, and exporters can claim a refund of input tax credit.
  • Essential Goods and Services: Common items like milk, fresh vegetables, unbranded cereals, eggs, curd, lassi, children’s drawing books, and healthcare and educational services are also exempt from GST.
  • Unpacked food grains and unbranded paneer are included in this category, ensuring basic food security remains untaxed.

5% GST Slab

  • Goods: Includes essential and daily-use items such as apparel up to ?1,000, agarbatti, cashew nuts, domestic LPG, coir mats, floor coverings, frozen vegetables, hearing aids, insulin, medicines, milk food for babies, packaged food, packed paneer, postage stamps, roasted coffee beans, pizza bread, revenue stamps, sugar, stents, sabudana, rusk, skimmed milk, tea, stamp post marks, and footwear priced below ?500.
  • Services: Road transport by motor cabs and radio taxis, restaurants with a turnover up to ?50 lakhs, tour operator services, sale of advertisement space, economy class air travel, and transport services like railways and airways.
  • Recent Change: Certain renewable energy devices and scrap materials also fall under the 5% or 12% slab, depending on their classification. Explore the modified GST rates for more clarity.

12% GST Slab

  • Goods: Ayurvedic medicines, apparel above ?1,000, almonds, butter, bhujia, animal fat sausage, chutney, chess and carrom boards, reagents, frozen meat, exercise books, fish knives, forks, fruit juices, ghee, jam, jelly, mobile phones, namkeen, notebooks, non-AC restaurants, pickles, packed coconut water, sewing machines, tongs, tooth powder, glasses for corrective spectacles, and umbrellas.
  • Services: Hotels, guest houses, and inns with tariffs between ?1,000 and ?2,500 per night, and business class air tickets.
  • Work contracts and certain processed foods are also taxed at 12%.

18% GST Slab

  • Goods: Aluminium foil, biscuits, bamboo, branded clothing, furniture, CCTV cameras, cakes, corn, curry paste, envelopes, footwear above ?500, hair oil, ice cream, mineral water, mayonnaise, monitors, paddling pools, pasta, printers, preserved vegetables, soups, soaps, salad dressing, steel products, tissues, tampons, toothpaste, weighing machines, and other consumer durables.
  • Services: Telecom services, AC hotels serving alcohol, IT services, and hotel rooms with tariffs between ?2,500 and ?5,000 per night.
  • Recent Revision: Sale of old and used electronically operated vehicles now attracts 18% GST instead of 12% on the marginal value.

28% GST Slab

  • Goods: Aerated water, personal aircraft, motorcycles, aftershave, ceramic tiles, chocolates without cocoa, dishwashers, deodorants, hair shampoo, dye, pan masala, shaving cream, shavers, paints, vacuum cleaners, washing machines, water heaters, luxury cars, and high-end consumer durables.
  • Services: 5-star hotels, gambling, betting in race clubs, hotels with room tariffs of ?5,000 and above, cinema, and entertainment. These enjoy a high tax rate due to the luxury nature of the services provided.
  • Many items in this slab also attract an additional compensation cess, especially luxury and sin goods like tobacco, aerated drinks, and large vehicles, with cess rates ranging from 1% to over 200%.

Input Tax Credit and Elimination of Cascading Effect

Previously, taxes like VAT and service tax resulted in a cascading effect, where tax was paid on tax due to non-availability of set-offs. GST eliminates this by allowing seamless input tax credit (ITC) across the supply chain. Tax is charged only on the value added at each stage.

Set-off Rules under GST:

  • IGST can be set off against IGST, CGST, and SGST liabilities. Learn about GST compliance for businesses.
  • CGST can be adjusted against IGST and CGST
  • SGST can be adjusted against IGST and SGST

Conclusion

GST has significantly simplified the indirect tax system in India by introducing a unified structure, promoting ease of doing business, and removing cascading tax burdens. Understanding GST applicability, framework, and credit mechanisms is essential for businesses to remain compliant and make the most of tax benefits.
