Performance Analysis of Goods and Services Tax (GST) in India (UPSC Economy)

The Goods and Services Tax came into force on 1 July 2017, replacing a thicket of central and state indirect taxes with a destination-based, credit-flowing tax on consumption. Eight years on, GST is India's largest indirect-tax experiment and one of its most ambitious federal bargains. Monthly collections have crossed Rs 1.8 lakh crore on a sustained basis, the taxpayer base has more than doubled, and most goods and services are taxed at rates well below the pre-GST aggregate. Yet persistent issues – inverted duty, multiple slabs, petroleum exclusion, compensation disputes – keep the reform unfinished.

Architecture of GST

Legal framework

• Central Goods and Services Tax (CGST) Act – Union levy on intra-state supplies.
• Integrated Goods and Services Tax (IGST) Act – Union levy on inter-state supplies.
• Union Territories GST (UTGST) Act – for UTs without legislature.
• GST (Compensation to States) Act – cess-backed revenue protection.
• Parallel State GST laws enacted by every state and UT with legislature.

Policy framework

Multiple rate structure: 0%, 5%, 12%, 18% and 28%, plus 0.25% for rough diamonds and 3% for gold. A Compensation Cess applies on demerit and luxury goods.

Administrative framework

• GST Council (Article 279A) decides rates, exemptions, thresholds.
• Centre and state tax administrations share assessee allocation and audit.
• GST Network (GSTN) is the IT backbone for registration, returns, refunds and e-way bills.

Achievements

One nation, one tax

Replaced the patchwork of CST, VAT, excise, service tax, octroi, entry tax and dozens of cesses with a unified credit-flowing tax. Removed inter-state checkposts; logistics costs dropped sharply.

Cascading effect eliminated

Input Tax Credit ensures tax is paid only on value added, not tax on tax.

Compliance gains

• Registered taxpayers rose from 64 lakh in July 2017 to over 1.5 crore in 2024.
• e-invoicing (mandatory above Rs 5 crore turnover), e-way bills and GSTR matching have squeezed the informal tax gap.
• Faceless scrutiny and risk-based audits have reduced discretion.

Formalisation and digitalisation

GST pulled small suppliers into the formal economy, forced digital record-keeping, and became a credit-history proxy for MSME lending.

Ease of doing business

Unified registration thresholds, common portal and predictable rates made multi-state operations easier, especially for services.

Revenue performance

• Monthly collections routinely above Rs 1.8 lakh crore.
• Record Rs 2.37 lakh crore in April 2025.
• Buoyancy above 1.2 in recent years.

Persistent Issues

Multiple rates

Seven rates (0, 0.25, 3, 5, 12, 18, 28) complicate classification and invite disputes. The original Revenue Neutral Rate of 15.5 per cent as envisaged by Arvind Subramanian's committee has not been achieved.

Inverted duty structure

When the GST rate on inputs exceeds that on outputs, producers accumulate unusable input tax credit. Textiles, fertilisers and footwear have faced acute distortions.

Coverage gaps

Petroleum crude, petrol, diesel, natural gas, aviation turbine fuel and electricity remain outside GST. This breaks the credit chain for transport, logistics and manufacturing, and denies states a share in buoyant fuel taxes.

Refund delays

Exporters have complained of working-capital stress from delayed IGST refunds. Fake-invoice rings exploiting input tax credit have been unearthed repeatedly.

Anti-profiteering framework

The National Anti-Profiteering Authority was replaced by the Competition Commission of India‘s jurisdiction in 2022, but guidelines on pass-through of rate cuts remain contested.

Compensation shortfall

The five-year GST compensation window ended in June 2022. States face a revenue adjustment after the protected 14 per cent annual growth lapsed. Compensation cess is being levied until March 2026 to service the Rs 2.69 lakh crore loan raised during COVID.

Revenue neutrality concerns

The 15th Finance Commission noted that the tax share of GST-subsumed revenue fell from 6.3 per cent of GDP in 2016-17 to around 5.7 per cent in the early GST years, before recovering. Post-pandemic, collections have normalised but remain below the pre-GST baseline in some states.

Dispute resolution

The GST Appellate Tribunal, long pending, was notified in 2023 and is slowly becoming functional. Until then, High Courts have absorbed GST litigation.

Small taxpayer burden

Composition scheme, Quarterly Return Monthly Payment (QRMP), and e-invoicing thresholds have eased compliance, but small businesses still complain of portal glitches and rule churn.

Reform Agenda

Rate rationalisation

A Group of Ministers under Bihar Deputy CM Samrat Choudhary in 2024 recommended collapsing the 12 per cent and 18 per cent slabs into a single mid-slab. The GST Council is examining a shift to a 3-rate structure – 5, 15 and 28 per cent – approaching the original RNR.

Petroleum inclusion

Including petrol, diesel and natural gas under GST would restore the credit chain and reduce fuel prices. States are cautious given the revenue implications.

Simplification

Unified returns, single registration, faster refunds, and AI-driven scrutiny.

Tribunal rollout

Full rollout of GST Appellate Tribunal benches across states.

Anti-evasion

Continued crackdown on fake invoicing via AI-based matching; track-and-trace for high-risk goods.

• Record collections: April 2025 saw Rs 2.37 lakh crore in gross GST, the highest ever. FY25 total crossed Rs 20 lakh crore.

UPSC Relevance

GST is a recurring GS III theme under taxation, federalism and infrastructure. Mains prompts test candidates on the performance of GST, rate rationalisation, compensation mechanism and inclusion of petroleum. Prelims can test Article 279A, GSTN, compensation cess sunset, and multi-rate structure. Essay linkages arise through one-nation-one-tax and cooperative federalism. Candidates should memorise collection figures, the GST Council's recent rate decisions, and the status of the Appellate Tribunal to write precise, data-rich answers.
