India's tax system: direct taxes, indirect taxes and GST

Taxes are the government's main source of revenue and its main tool for redistribution. Direct taxes, such as income tax and corporation tax, are paid by the person or firm on whom they are levied and cannot easily be shifted to someone else. They can be progressive, with higher rates on higher incomes, and they allow personal allowances and deductions. Indirect taxes, such as the Goods and Services Tax, are collected from sellers but borne by buyers through prices, and they tend to be regressive in effect, because poorer households spend a larger share of income on taxed consumption, even if necessities are exempt or taxed at lower rates.

Before 2017, India had a fragmented indirect tax system, with central excise duty, service tax, state value added tax, octroi and other levies creating cascading taxes on taxes and barriers between states. The Goods and Services Tax, launched on 1 July 2017 through the 101st Constitutional Amendment of 2016, replaced most of these with a destination-based tax on value added, with input tax credit preventing cascading in principle. GST has central and state components, an integrated tax on inter-state supplies, and a council of Union and state finance ministers to decide rates and rules, though the council's decisions and compensation to states for revenue loss have been contested.

Direct taxes have their own debates. Personal income tax has been reformed through new and old regimes with different slabs and deductions, while corporation tax rates were cut in 2019 to attract investment, with supporters citing competitiveness and critics citing revenue loss. Tax administration has moved towards faceless assessment, pre-filled returns and data matching to reduce discretion and harassment, though taxpayers still complain about notices, delays and complexity. The tax-to-GDP ratio, the share of national income collected as tax, is watched as a measure of state capacity: a low ratio limits public services, while a high ratio without good services undermines consent to taxation.

For civil studies, taxation links economics to the social contract. Who is taxed, what is exempted, how honestly taxes are collected and how revenues are spent decide whether citizens see taxation as fair. Exemptions for agriculture, small businesses or particular sectors may serve social goals but narrow the base and create lobbying for special treatment. A good tax system is therefore judged not only by revenue raised, but by simplicity, fairness, predictability and the quality of public services it funds.
