Goods and Services Tax: 9 Years of GST Reforms

Why in News?

The Goods and Services Tax completed nine years on July 1, 2026. Introduced in 2017, GST replaced multiple Central and State indirect taxes with an integrated tax framework. Over the years, rate rationalisation, digital compliance systems and Centre–State coordination has strengthened its role in creating a common national market.

What is GST?

• The Goods and Services Tax is an indirect tax levied on the supply of goods and services for domestic consumption.
• Although consumers ultimately bear the tax, businesses collect it at the point of sale and deposit it with the government.
• GST is imposed on the value added at each stage of the supply chain. Through Input Tax Credit, a business can deduct the tax already paid on inputs from its final tax liability, thereby reducing the cascading effect of taxation.

Evolution of GST in India

2003:

• The Kelkar Task Force on Indirect Taxes recommended the introduction of a comprehensive GST.

2006:

• The Union Budget proposed the implementation of a national GST.

2014:

• The Constitution Amendment Bill was introduced as the 122nd Constitutional Amendment Bill.

2016:

• The Bill was enacted as the Constitution (101st Amendment) Act, 2016.

2017:

• GST came into force across India on July 1, 2017.
• It subsumed 17 taxes and 13 cesses, replacing a fragmented indirect-tax system with a more uniform framework.

Constitutional Framework

Article 246A

• It grants Parliament and State Legislatures concurrent powers to make GST laws.
• However, Parliament has exclusive authority to legislate on GST relating to inter-State trade or commerce.

Article 269A

• It deals with GST on inter-State supplies.
• The Union government levies and collects the tax, which is then apportioned between the Centre and States.

Article 279A

• It provides for the establishment of the GST Council by the President.
• The Council recommends tax rates, exemptions, threshold limits, procedural rules and special provisions.

Salient Features of GST

Tax on supply:

• GST is levied on the supply of goods and services rather than separately on manufacture, sale or service.

Destination-based tax:

• Tax revenue generally accrues to the State where the final consumption takes place.

Value-added taxation:

• Input Tax Credit prevents repeated taxation of the same value.

Dual structure:

• Both the Union and State governments levy GST on intra-State supplies.

Common national market:

• Uniform principles reduce internal tax barriers and support inter-State trade.

Digital administration:

• Registration, return filing, tax payment, invoice reporting and refund processing are largely electronic.

Components of GST

Central Goods and Services Tax

• CGST is levied by the Union government on intra-State supplies.

State Goods and Services Tax

• SGST is levied by the concerned State government on the same intra-State transaction.

Union Territory Goods and Services Tax

• UTGST applies to intra-Union Territory supplies in applicable Union Territories, together with CGST.

Integrated Goods and Services Tax

• IGST is levied by the Union government on inter-State supplies and imports. Its proceeds are shared with the destination State.

Taxes Subsumed under GST

Major Central levies

GST replaced taxes such as:

• Service Tax
• Central Excise Duty on covered goods
• Additional Duties of Customs
• Special Additional Duty of Customs
• Relevant Central cesses and surcharges

Major State levies

It subsumed:

• State VAT or Sales Tax on covered goods
• Purchase Tax
• Luxury Tax
• Entry Tax and Octroi
• Entertainment Tax, except local-body levies
• Taxes on lotteries, betting and gambling
• Relevant State cesses and surcharges

Items and Levies Outside GST

Alcoholic liquor for human consumption

It remains outside the scope of GST and is taxed by States.

Petroleum products

GST may be imposed on the following products from a date recommended by the GST Council:

• Petroleum crude
• Petrol
• High-Speed Diesel
• Natural gas
• Aviation Turbine Fuel

Until then, excise duty and State VAT continue to apply.

Other independent levies

These include:

• Basic Customs Duty
• Stamp Duty
• Motor Vehicle Tax
• Electricity Duty
• Toll Tax
• Anti-dumping and safeguard duties
• Certain local-body taxes

GST Council and Cooperative Federalism

The GST Council is a constitutional body under Article 279A.

It brings the Union and States together to decide:

• Tax rates
• Exemptions
• Threshold limits
• Model laws
• Procedural rules
• Special provisions for States

Because both levels of government share the GST base, the Council has become an important institution of cooperative fiscal federalism.

Goods and Services Tax Network

The GSTN provides the digital infrastructure for the GST system.

It supports:

• Registration
• Return filing
• Electronic payments
• Refunds
• E-invoicing
• Input Tax Credit matching
• Data exchange among tax authorities

GSTN connects the Centre, States, taxpayers and other stakeholders through a common technological platform.

Next-Generation GST Reforms

The 56th meeting of the GST Council approved a new phase of reforms that came into effect in September 2025.

Simplified rate structure:

The tax system was primarily reorganised around the 5% and 18% slabs.

Luxury and sin goods:

A higher 40% rate was introduced for specified luxury and demerit goods.

Consumer relief:

Rate reductions and exemptions were aimed at improving affordability of selected essential goods and services.

Correction of inverted duty structures:

Changes sought to reduce situations where tax on inputs exceeded tax on finished products.

Easier compliance:

Registration, refunds and return filing were simplified, especially for MSMEs and start-ups.

Relief for MSMEs and Small Taxpayers

Higher registration threshold

• The GST registration threshold for suppliers of goods was increased from ₹20 lakh to ₹40 lakh, subject to applicable conditions.

Composition Scheme

• Eligible small taxpayers can pay tax at a prescribed rate on turnover with simpler return and record requirements.

The turnover limit was raised to ₹1.5 crore for eligible taxpayers.

QRMP Scheme

• The Quarterly Return Monthly Payment Scheme allows taxpayers with annual turnover up to ₹5 crore to file returns quarterly while paying tax monthly.

NIL returns through SMS

• Taxpayers with no transactions can file specified NIL returns using SMS.

E-commerce relief

• Eligible small suppliers making intra-State supplies through e-commerce operators were exempted from compulsory registration under prescribed conditions.

Dispute relief

• Measures were introduced to reduce appeal pre-deposits and provide conditional waiver of interest and penalties for certain past demands.

Technology-Driven Tax Administration

E-invoicing:

Real-time invoice reporting improves accuracy and reduces fake invoicing.

Automated reconciliation:

Supplier tax liability is matched with the recipient’s Input Tax Credit claims.

Pre-filled returns:

System-generated information reduces repetitive reporting and manual errors.

Artificial Intelligence and analytics:

AI and machine learning identify suspicious registrations, invoice patterns and tax-evasion risks.

Risk-based scrutiny:

Authorities can focus on high-risk taxpayers while reducing unnecessary intervention for compliant businesses.

This shift has made tax administration more transparent, data-driven and predictable.

Major Achievements

Unified national market:

GST reduced internal tax barriers and improved the movement of goods and services across States.

Reduction of cascading:

Input Tax Credit lowered the burden of tax on tax.

Wider tax base:

The number of registered GST taxpayers increased from about 66.5 lakh in 2017 to 1.65 crore by May 2026.

Higher collections:

Gross GST collections increased from approximately ₹7.4 lakh crore in 2017–18 to ₹22.27 lakh crore in 2025–26.

Economic formalisation:

Digital invoices and return filing brought more firms and transactions into the formal economy.

Ease of doing business:

A common framework replaced multiple State-level tax procedures.

Transparency:

Electronic records created an auditable trail for transactions and tax payments.

Revenue buoyancy:

Improved compliance and reporting strengthened fiscal transparency and predictability.

Way Forward

• Continue rate rationalisation while safeguarding revenue stability.
• Reduce classification disputes and inverted duty structures.
• Make refunds faster and largely automated.
• Protect genuine Input Tax Credit claimants through proportionate enforcement.
• Strengthen GSTN capacity, cybersecurity and grievance redressal.
• Use AI-based scrutiny transparently and fairly.
• Consider phased inclusion of petroleum products through GST Council consensus.

Conclusion

GST is one of India’s most important structural tax reforms. It replaced a fragmented indirect-tax system with a destination-based, digitally administered and nationally integrated framework. Its achievements include a wider tax base, higher collections, reduced cascading and greater formalisation. However, GST remains an evolving reform. The next phase should focus on simpler rates, easier compliance, faster refunds, stable State finances and taxpayer trust.
