Key Features of VAT and GST: What Makes Them Stand Out?

India’s indirect tax landscape has undergone two defining transformations in the last two decades – the introduction of Value Added Tax (VAT) in 2005, and its eventual successor, the Goods and Services Tax (GST), which came into force on 1 July 2017. While both are consumption-based taxes designed to bring efficiency and fairness to the tax system, they differ significantly in scope, structure, and reach. Understanding what makes each of them stand out – and why one had to give way to the other – is essential for anyone studying business law in India.

What is VAT and how does it work? 🔗

Value Added Tax (VAT) is a multi-point, indirect tax levied at each stage of the production and distribution chain – not just at the final point of sale. What makes it fundamentally different from the older sales tax regime is the input tax credit (ITC) mechanism: a registered dealer can deduct the tax already paid on purchases (input tax) from the tax collected on sales (output tax). Only the difference is deposited with the government. This ensures that tax is effectively levied only on the value added at each stage, rather than on the full accumulated cost of the product.

For example, if a manufacturer sells goods to a retailer for ₹100 and the VAT rate is 10%, the manufacturer collects ₹10 as VAT. The retailer then sells the goods to a consumer for ₹150 and collects ₹15 as VAT – but since the retailer already paid ₹10 as input tax, they remit only ₹5 to the government. The final consumer bears the entire tax burden, but it arrives at the government in stages – making the process transparent and traceable.

Salient features of VAT 🔗

Multi-point taxation with credit mechanism 🔗

Unlike single-point sales tax, VAT is levied at every stage where value is added – from manufacturer to wholesaler to retailer. However, through the input tax credit system, each registered dealer in the chain pays tax only on their own value addition. This eliminates the cascading effect, where earlier tax regimes taxed goods on their full price including previously paid taxes, effectively creating a “tax on tax.”

Destination-based consumption tax 🔗

VAT follows the destination principle – meaning tax revenue accrues to the state where the goods are finally consumed, not where they are produced. This ensures a more rational distribution of tax revenue, though, as India found later, applying it at the state level created uneven outcomes.

Methods of computing VAT 🔗

There are two primary methods of computing VAT. The invoice or tax-credit method is the most widely used globally. Under this method, the dealer pays output tax on each sale, claims credit for input tax paid on purchases, and remits the net amount. Most countries prefer the invoice method because of its flexibility, particularly for zero-rating exports under the destination principle. The second approach is the subtraction method, where tax is applied directly to the value added (selling price minus purchase price). Japan used this method briefly, but it is rarely adopted.

Rate structure under state VAT 🔗

VAT rates in India were broadly divided into four categories: a nil rate for exempt goods (such as basic foodstuffs and items in the unorganised sector), 1% for precious metals like gold and silver, 4-5% for essential commodities like medicines and cooking oil, and a higher rate of 10-12% for other taxable goods, known as the Revenue Neutral Rate (RNR). Special rates also applied – for instance, 20% on liquor in many states.

Exemptions and exclusions 🔗

Under the state VAT framework, certain categories of goods were fully exempt – typically items considered necessities, agricultural produce, and goods reserved for the unorganised sector. The taxable commodities were listed in separate schedules with fixed rates, and states attempted to maintain uniform rates to prevent tax-driven trade diversion between neighbouring states.

Operational mechanism: registration and returns 🔗

VAT registration was mandatory for all manufacturers and dealers above a prescribed turnover threshold. Registered dealers were required to calculate and report their VAT liability for each tax period, typically monthly, by reconciling output and input tax. The system proposed computerisation to flag non-compliant dealers and generate exception reports, reducing direct interference between the taxpayer and the tax officer.

Advantages of VAT 🔗

VAT offered several improvements over the earlier sales tax system. It eliminated the cascading effect of taxes, which had artificially inflated the price of goods. Its multi-stage collection structure made tax evasion harder – each stage in the supply chain required invoices to claim credit, thereby creating a natural audit trail. VAT also introduced uniform rates across the state, simplifying filing procedures and reducing discretionary powers of assessing officers. This built greater fairness and predictability into the tax system.

One of VAT’s key social objectives was to protect the purchasing power of lower-income groups. Since essential goods were either exempt or taxed at lower rates, and cascading was eliminated, VAT did not cause significant price inflation for everyday commodities.

Disadvantages and limitations of VAT 🔗

Despite its merits, VAT had significant shortcomings. First, it was a state-level tax – every state had its own VAT legislation, its own rates, its own schedules, and its own compliance procedures. This created a fragmented market. A business operating across multiple states had to navigate different legal frameworks for each state, increasing compliance costs.

Second, VAT applied only to goods, not services. Service tax was levied separately by the Central Government, and there was no cross-credit mechanism between the two. A trader paying VAT on goods purchased could not set it off against service tax liability, and vice versa – leading to continued cascading at the VAT-service tax interface.

Third, inter-state trade fell outside the VAT framework and was instead governed by Central Sales Tax (CST), which was origin-based rather than destination-based – directly conflicting with the logic of VAT itself.

Critics have also pointed out that VAT, as a consumption tax, tends to be regressive – the poor spend a higher proportion of their income on goods and therefore bear a relatively heavier tax burden compared to higher-income groups. Additionally, the extra accounting burden on small businesses was a practical concern.

The transition to GST: why VAT was not enough 🔗

VAT was a crucial step in modernising India’s indirect tax structure, but it was never the complete solution. It covered only goods, operated at the state level, and coexisted with a complicated web of central taxes – central excise duty, service tax, additional customs duties, cesses, and surcharges – with no unified credit mechanism linking them. The resulting structure had no uniformity of tax rates across states, and prices were artificially inflated because tax was paid on tax at multiple points without the ability to cross-claim credits.

The idea of a nationwide GST was first proposed by the Kelkar Task Force in 2000. The concept was simple: replace the entire complex web with a single, comprehensive, destination-based tax on the supply of both goods and services. After years of deliberations between the Centre and states, GST was finally implemented on 1 July 2017 through the Constitution (101st Amendment) Act, 2016, replacing taxes such as central excise duty, service tax, VAT, entertainment tax, octroi, and many others.

Salient features of GST 🔗

Comprehensive, multi-stage, destination-based tax 🔗

GST is comprehensive because it has replaced most indirect taxes at both the central and state level. It is multi-staged because it is levied at every stage of the production process, but tax paid at each stage is available as input credit to the next. And it is destination-based, meaning the tax revenue goes to the state where the goods or services are consumed, not where they originated.

Dual structure: CGST, SGST, and IGST 🔗

Given India’s federal structure, a single nationwide GST alone would deprive states of their fiscal autonomy. India therefore adopted a concurrent dual GST model. Both Central GST (CGST) and State GST (SGST) are levied simultaneously on every intra-state transaction. For inter-state transactions, Integrated GST (IGST) – roughly equal to CGST plus SGST – is collected by the Centre and apportioned to the consuming state. This model, also followed by Canada and Brazil, ensures that both levels of government retain taxation powers while the market remains unified.

Elimination of cascading through ITC 🔗

Under GST, a registered business can claim input tax credit on all taxes paid at previous stages, as long as the inputs are used for business purposes and the supplier has filed their returns. Tax is calculated only on the value addition at each stage of transfer of ownership – removing the earlier problem where excise duty was first levied by the Centre, then VAT was levied by the state on the full price including excise duty.

Tax slabs and rate structure 🔗

Under GST, goods and services are categorised into tax slabs of 0%, 5%, 12%, 18%, and 28%. Essential commodities are exempt or zero-rated; luxury and demerit goods attract the 28% rate plus an additional compensation cess. Precious metals like gold attract a special rate of 3%, and rough precious stones are taxed at 0.25%.

GST Council: the apex decision-making body 🔗

The GST Council, chaired by the Union Finance Minister and comprising state finance ministers, was established to make collaborative decisions on tax rates, exemptions, and administrative procedures. It operates on the principle of consensus and has the power to recommend changes to rates and rules – making it a unique constitutional body that bridges the Centre-state fiscal relationship.

Technology-driven compliance 🔗

GST compliance is almost entirely digital. Taxpayers register, file returns, make payments, and track credits through the common GST portal, with mechanisms like e-invoicing and e-way bills adding further layers of verification to reduce tax evasion. The GST Network (GSTN), a not-for-profit entity jointly set up by the Centre and states, provides the entire IT backbone for the system.

Anti-profiteering provisions 🔗

One notable feature of GST is the built-in anti-profiteering framework. Businesses are required to pass on the benefit of reduced tax rates or increased input tax credits to consumers by lowering prices. A National Anti-Profiteering Authority was constituted to monitor and enforce this.

Advantages of GST 🔗

GST’s most significant achievement is the creation of a unified national market. By replacing origin-based taxes like CST with a destination-based unified tax, it removed the fiscal barriers between states. Trucks no longer queue at state checkpoints for tax verification – the Ministry of Road Transport and Highways noted a 20% drop in interstate travel time following the disbanding of interstate check posts. Businesses now operate under a single tax law across the country, reducing compliance costs substantially for those with multi-state operations.

GST has also significantly broadened the tax base by bringing a larger number of businesses – especially in services – into the formal tax net. The shift to digital compliance has made it harder to evade taxes, as input credit claims are verified against supplier-filed invoices.

Challenges and criticisms of GST 🔗

GST has not been without difficulties. Small businesses with limited resources have struggled to adapt to the frequent changes in rules, multiple return filings, and digitally-intensive compliance requirements. The dual structure itself creates complexity: businesses must determine correctly whether a transaction is intra-state or inter-state before deciding whether to pay CGST+SGST or IGST – and an error in classification can result in paying the correct tax again along with penalties, followed by a refund claim for the wrongly paid amount.

Certain sectors – petroleum products, alcohol for human consumption, and electricity – remain outside the GST net and continue to be governed by the old VAT and excise framework. This creates a continued disconnect in the supply chain for industries like aviation, transportation, and manufacturing that heavily depend on fuel, since they cannot claim ITC on fuel costs.

Manufacturing states were also initially concerned that a destination-based tax would shift revenue towards consuming states. To address this, the Centre committed to compensating states for revenue losses for five years, funded through a GST Compensation Cess – a mechanism that had to be extended beyond the original deadline due to the economic disruptions caused by the COVID-19 pandemic.

VAT and GST: a comparative summary 🔗

VAT was an important stepping stone – it introduced the concept of multi-stage taxation with input credit and moved India away from the cascading sales tax regime. But it was always a partial reform: it covered only goods, operated at the state level, and could not resolve the fragmentation caused by different state laws and the parallel service tax system. GST completed the journey. It unified goods and services under a single tax, extended the destination principle nationwide, and created the infrastructure for technology-driven compliance at a scale that VAT never could. Together, they represent the arc of India’s indirect tax reform – from fragmented and opaque to integrated and transparent.

What do you think? VAT gave states control over their own revenue while GST centralised rate-setting through the GST Council – do you think this shift has adequately protected the fiscal autonomy of smaller states? And given that petroleum and alcohol remain outside GST, creating input credit gaps for several industries, should these sectors eventually be brought under the GST framework?
