Tax Reforms in India: Direct and Indirect Tax Structure

July 19, 2026

TOPIC CLASSIFICATION

Subject: Economy — Public Finance and Fiscal Policy
Sub-topic: Tax Structure — Direct vs Indirect Taxes, GST, Income Tax, Corporate Tax, Customs, Excise, Tax Buoyancy, Tax Reforms (1991 onwards), Tax-to-GDP Ratio, Taxation and Federalism
Mains GS Paper-III: Indian Economy — taxation structure, tax reforms, GST, direct tax code, tax evasion and black money.


EXAMINER REASONING

Tax reforms are central to India's fiscal story — from the 1991 tax reforms to the landmark GST (2017). Prelims tests: direct vs indirect tax components, GST Council structure, tax slabs, cesses and surcharges, tax-to-GDP ratio, FRBM targets. Mains demands: (a) the pre-GST indirect tax regime — cascading taxes, state-vs-centre taxation, VAT, excise, (b) GST as a transformative reform — structure (CGST, SGST, IGST), rates, compensation mechanism, ITC, (c) direct tax reforms — Direct Taxes Code (attempted), corporate tax rate cut (2019), new income tax regime (2020), (d) tax buoyancy vs tax effort — India's low tax-to-GDP (~11.5% vs OECD ~34%), (e) tax evasion and black money — demonetisation, Benami Act, FATCA, (f) federal aspects — GST Council, divisible pool, Finance Commission. The examiner's favourite framing is: "Has GST achieved the goal of 'One Nation, One Tax'?"

Pre-GST Indirect Tax Regime — The Problems

ProblemDescriptionPre-GST Example
Cascading (Tax on Tax)Excise levied on manufacturing → VAT on excise-inclusive price → no set-offA product paid tax at every stage
Multiple taxesCentral: excise, CST, service tax, customs, surcharges — State: VAT, entry tax, luxury tax, entertainment tax, octroiOver 15 different indirect taxes
No seamless ITCInput Tax Credit not available across stages — cascading costs built into priceManufacturer could not claim credit for service tax paid
Check-posts and delaysState border check-posts for CST — trucks spent 10-20 hours at borders60% truck time wasted at check-posts
Tax evasionNon-VAT states (before 2005) — no chain of invoices — easy evasionUnder-invoicing, missing trader fraud

GST — Goods and Services Tax (2017)

AspectDetail
Constitutional Basis101st Constitutional Amendment Act, 2016 — Art. 246A, 269A, 279A
GST CouncilArt. 279A — Union FM + State FMs — recommends rates, exemptions, threshold
Rate Structure0% (essential items), 5% (common use), 12% (standard), 18% (standard), 28% (luxury/demerit) + cess on 28% items
CGSTCollected by Centre — on intra-state supply
SGSTCollected by State — on intra-state supply
IGSTCollected by Centre — on inter-state supply + imports (Integrated GST)
Compensation5-year guarantee (2017-2022) — states guaranteed 14% revenue growth — extended via borrowing mechanism (2020-22)
ITC (Input Tax Credit)Seamless chain — credit of CGST/SGST/IGST available across the value chain — but subject to matching returns

Statement Elimination Guide

StatementTruth ValueWhy?
"GST is a single tax on all goods and services in India"FalseGST has multiple rates (0%, 5%, 12%, 18%, 28%) — and petroleum, alcohol, electricity are outside GST
"The new income tax regime is optional"FalseFrom FY 2023-24, the new regime is the default regime — the old regime is available by choice
"The GST Council's decisions are binding on all states"TrueThough the Council's recommendations are not legally binding by the Constitution, they have been uniformly implemented by consensus
"Corporate tax in India is one of the highest globally"FalseAfter the 2019 cuts, India's corporate tax rate (22%) is competitive — lower than USA, Japan, Germany
"The tax-to-GDP ratio of India is above the global average"FalseIndia's ~11.5% is below the emerging market average of ~18% and far below OECD ~34%

Current Affairs Hook

2023-26: GST compensation — the compensation period ended June 2022; the GST Council extended the levy of compensation cess until March 2026 to repay loans taken during COVID. Rate rationalisation — the Group of Ministers (GoM) on rate rationalisation has recommended merging the 12% and 18% slabs into a single ~15-16% slab. New Income Tax Regime — made default from FY 2023-24; the old regime still available but narrowing. Vivad se Vishwas 2.0 (2024) — direct tax dispute resolution scheme. Customs duty reforms — the 2023-24 Budget rationalised customs duties for electronics, solar cells. GST on online gaming — 28% GST on full face value (demand) — challenged in Supreme Court. Tax buoyancy concern — while GST collections are record-high, the tax-to-GDP ratio is still stagnant.


Interlinkages

  • → Federalism (GS-II): GST Council is a unique federal institution — cooperative federalism in action
  • → Fiscal Policy (GS-III): Tax revenue determines fiscal capacity — FRBM deficit targets depend on tax buoyancy
  • → Budget (GS-III): Direct and indirect tax estimates are the foundation of the Union Budget
  • → Black Money (GS-III): Tax evasion reduction through GST's invoice matching
  • → Investment (GS-III): Corporate tax cuts aimed at boosting Make in India, PLI schemes
  • → State Finance (GS-II): State GST revenues, compensation, Finance Commission devolution

Common Mistakes

MistakeCorrection
"GST subsumed all indirect taxes"Petroleum, alcohol, electricity, stamp duty, and toll tax are outside GST
"The GST Council's decisions require a unanimous vote"Decisions require 3/4th majority — Centre has 1/3 vote, states 2/3
"The new income tax regime has more exemptions than the old regime"The new regime has no exemptions (no 80C, HRA, etc.) — lower rates but fewer deductions
"Corporate tax rate in India is 30%"The base rate was reduced to 22% for existing companies and 15% for new manufacturing (2019)
"Wealth tax is still applicable in India"Wealth tax was abolished in 2015 — replaced by a surcharge on high-income earners
