GST and Indian Tax System Notes for UPSC

A tax is a compulsory payment made by people and businesses to the government, without any direct benefit in return. Taxes pay for roads, schools, defence, hospitals and welfare schemes. The Goods and Services Tax (GST), launched on 1 July 2017, is the biggest indirect tax reform in India since independence. For the UPSC Civil Services Examination, this topic is asked in Prelims through the GST Council, tax rates, the constitutional amendment and the difference between direct and indirect taxes, and in Mains through the effect of GST on federalism, trade and the economy. This note gives you all of it in simple language.

Direct and Indirect Taxes

Direct taxes are collected by the Central Board of Direct Taxes (CBDT), and indirect taxes by the Central Board of Indirect Taxes and Customs (CBIC). Both come under the Department of Revenue of the Ministry of Finance. India has moved over the years towards a simpler tax system with a wider base and fewer exemptions.

Why GST Was Needed

Before GST, India had a complex system. The Centre charged central excise duty, service tax and customs duty, and the states charged VAT, entry tax, octroi, luxury tax and entertainment tax. One product could be taxed many times as it moved from the factory to the shop. This was called the cascading effect or tax on tax. Different states had different rates, long queues of trucks waited at state check posts, and businesses spent much time on paperwork. The idea was to create "One Nation, One Tax, One Market".

Constitutional Basis

GST was introduced through the 101st Constitutional Amendment Act, 2016. It added Article 246A, which gives both Parliament and state legislatures the power to make laws on GST; Article 269A for GST on inter-state trade; and Article 279A, which created the GST Council. The GST laws passed were the Central GST Act, the Integrated GST Act, the Union Territory GST Act, the GST (Compensation to States) Act and the State GST Acts. Alcohol for human consumption is outside GST, and petroleum products (crude, petrol, diesel, natural gas and aviation turbine fuel) are still outside GST at the moment, which is a common point for questions.

Types of GST

• CGST (Central GST): collected by the Centre on intra-state supplies.
• SGST (State GST): collected by the state on intra-state supplies. Union Territories without legislature levy UTGST.
• IGST (Integrated GST): collected by the Centre on inter-state supplies and imports, and then shared with the destination state.

GST is a destination-based tax, which means the tax goes to the state where the goods or services are consumed, not where they are produced. This benefits consuming states such as Bihar and Uttar Pradesh, but producing states needed compensation in the early years. The compensation to states for revenue loss was provided for five years until June 2022 and funded by a cess on luxury and sin goods.

The GST Council

The GST Council is a constitutional body under Article 279A. Its chairperson is the Union Finance Minister, the Union Minister of State for Finance is a member, and the finance ministers of all states and Union Territories with legislatures are members. Decisions are taken by a three-fourths majority of the weighted votes: the Centre has one-third of the votes and all the states together have two-thirds. This gives the Centre a veto power in a way, as no decision can pass without its support, while the states together cannot be ignored. It decides tax rates, exemptions, thresholds, special rules for some states and dispute handling. The Council is often called a model of cooperative federalism, but critics say the states have lost fiscal autonomy.

GST Rate Structure

GST has a multi-slab structure. The main slabs have been 5, 12, 18 and 28 percent, plus a nil rate for essential items such as fresh vegetables and milk, a special rate of 3 percent for gold and silver, and 0.25 percent for rough diamonds. Luxury and sin goods, such as tobacco and big cars, also paid a compensation cess. The Council has reformed and simplified rates over time, and a major rationalisation of slabs was undertaken in 2025. The rate list changes often, so check the latest rates from the GST portal before the examination.

Input Tax Credit (ITC)

The heart of GST is the Input Tax Credit. A business that pays tax on its inputs can deduct it from the tax it collects on its output, and so tax is paid only on the value added at each stage. Take an example: a baker pays 18 rupees of tax on flour, collects 30 rupees of tax on the sale of bread, and pays only the balance of 12 rupees to the government. This removes the cascading effect and brings every business into a chain, which improves compliance and makes the economy more formal.

Direct Tax System in India

The main direct taxes are personal income tax, charged on individuals under the Income-tax Act, with slab rates and a new simplified regime; corporation tax, charged on company profits (India cut the rate to 22 percent for existing firms and 15 percent for new manufacturing firms in 2019); and capital gains tax, charged on profits from selling assets, with different rates for short-term and long-term gains. Other direct taxes include the securities transaction tax and the dividend tax rules. The government has used faceless assessment and e-filing to reduce corruption and speed up service. The new Income-tax Act is aimed at replacing the 1961 law with a simpler text.

Benefits and Problems of GST

The benefits of GST are a single national market, no cascading of tax, easier movement of goods, higher tax compliance, growth of the formal economy and a larger tax base. The monthly collections have crossed 1.5 to 2 lakh crore rupees, showing a strong improvement in revenue. The problems are multiple slabs, frequent rate changes, complicated filing for small businesses, delays in refunds, the exclusion of petrol and alcohol, and disputes between the Centre and states over compensation and revenue sharing. Reforms like the e-invoice, the e-way bill, a single registration portal and a GST Appellate Tribunal are meant to reduce these problems.

Other Taxes and Concepts

A cess is a tax on tax collected for a particular purpose, like the Health and Education Cess; it is not shared with states. A surcharge is an extra charge on high-income taxpayers. Customs duty is charged on imports and exports. The Tax Information Exchange agreements and the General Anti-Avoidance Rule (GAAR) are used to prevent tax evasion. A progressive system, with higher rates for higher incomes, supports equity, while simpler taxes support efficiency. Good tax policy balances both.

GST and Federalism: The Mains Angle

GST is a unique experiment in sharing power. The Centre and the states gave up their separate rights to tax goods and services and agreed to decide rates together in one council. Supporters say this is cooperative federalism at its best, because every state has a voice and decisions are taken after discussion. Critics point out that the states have given up an important source of their own revenue and now depend on the Council and on compensation. Disputes over delayed compensation and the legal status of the Council's decisions show that the balance is still evolving. In a Mains answer, present both views, give one or two examples, and finish with a suggestion, for example that transparent data sharing and a permanent dispute-resolution forum can build more trust between the Centre and the states. Also mention that GST helps the poor only if lower rates on essential goods are protected and prices actually fall for consumers.

Quick Revision

• GST launched on 1 July 2017 by the 101st Amendment; Articles 246A, 269A and 279A.
• GST is destination-based with CGST, SGST and IGST.
• GST Council: chaired by the Union Finance Minister; decisions by three-fourths weighted majority.
• Petrol, diesel and alcohol are outside GST at present.
• CBDT handles direct taxes; CBIC handles indirect taxes.

GST changed the way India collects tax and the way the Centre and states share power. Keep the Articles, the council structure and the three types of GST ready, and follow the latest rate changes, and you will find this topic easy and scoring.
