It has resulted in transformative changes to consumers, businesses, and government revenues alike. This article explores the benefits of GST, discusses the various taxes it replaced, and provides insights into why GST is considered a milestone in the economic reforms of India.

What is GST?

Goods and services tax (GST) is a form of indirect tax levied on all goods and services sold or rendered for domestic purposes. The tax amount is added to the total price of the product or the service. GST is structured into five tax slabs — 0%, 5%, 12%, 18%, and 28% and is collected in four forms. The IGST (integrated tax) is shared by the Centre and states on inter-state transactions, CGST is collected by the Central Government, SGST is collected by state governments, and UTGST is collected by the union territory governments.

Advantages of GST

Here are the key benefits of ‘One Nation, One Tax’:

Elimination of the Cascading Effect

The GST is a comprehensive indirect tax which brings indirect taxation under one umbrella, removing the ‘tax on tax’ burden. Before the introduction of GST, taxes were levied on already-taxed goods or services. GST eliminates the cascading effect by allowing seamless input tax credits and lowering the overall tax load, benefiting both businesses and consumers.

Simplified and Easy Compliance

GST has consolidated and subsumed several indirect taxes into a single system, easing the compliance process significantly. This has especially benefited small and medium enterprises (SMEs), which now have reduced paperwork and fewer legal complexities.

Uniformity of Tax Rates and Structures

GST has harmonised indirect tax rates and structures nationwide, increasing certainty and ease of doing business. This uniformity creates a fairer, more transparent business environment, irrespective of the choice of place of doing business.

Improved Competitiveness

The GST improves competitiveness for trade and industry by reducing transaction costs and improving transparency. Greater operational efficiency and trust among stakeholders help to drive profitability, sales and market expansion. Implementation of GST and dismantling of interstate check posts are considered as one of the crucial steps to improve the competitiveness of India’s manufacturing sectors.

Gain to Manufacturers and Exporters

By merging central and state taxes, allowing input tax credit , and phasing out CST, GST reduces the cost of locally manufactured goods and services, thereby benefiting the manufacturers and exporters. This supports exports and boosts the global competitiveness of Indian products and services.

Higher Revenue Efficiency

GST has enhanced the efficiency of the collection of tax, boosting revenues for both central and state governments.

Reduction in Overall Tax Burden

The input tax credits paid at each stage can be claimed at the next stage of value addition, making GST fundamentally a tax only on the value added at each step. The final consumer will have to bear only the GST charged by the last dealer in the supply chain, claiming the set-off benefits at all the previous stages. GST decreases and lowers the average tax burden, translating to decreased production costs and, in many cases, lower consumer prices.

Reduced Tax Evasion

GST is equipped with a robust IT infrastructure. Its streamlined and digitised framework strengthened transparency, reducing corruption and curbing tax evasion.

Simpler Administration

The GST is easier not only for consumers and businesses but also for the government to administer. The streamlined indirect taxation system has decreased the administrative overheads, making tax management more efficient and cost-effective for all stakeholders.

How Does GST Eliminate the Cascading Effect or ‘Tax on Tax’?

The term ‘tax on tax’ , also known as the cascading effect of taxes , refers to double taxation where a tax is levied on an amount that already includes another tax. This increases the overall tax burden and inflates the final price of goods and services.GST provides seamless input tax credits (ITC), allowing businesses to offset the taxes they pay on inputs (purchases) against the taxes they collect on outputs (sales). This eliminates the cascading effect and reduces the effective tax cost. Let us take an example to understand this before and after the GST.

Before the GST regime After GST
A service provider offering services for say, ₹50,000 is charged a service tax of 15%. He/she pays ₹7,500 (₹50,000 * 15%) as service tax. The same service provider offering services for ₹50,000 pays GST @18% = ₹9,000 Total: ₹59,000
Then, say, he/she buys office supplies for ₹20,000, paying 5% as VAT of ₹1,000 (₹20,000 *5%). On office supplies of ₹20,000, GST @5% = ₹1,000.
Under the old system before GST regime, the service provider cannot claim credit for the ₹1,000 VAT paid on supplies against the ₹7,500 service tax. Total tax outflow = ₹7,500 (service tax) + ₹1,000 (VAT) = ₹8,500. With GST input tax credit, the service provider can get an offset of the ₹1,000 GST paid on supplies against the ₹9,000 GST collected on services. Total tax outflow - ₹9,000 (GST on services)

GST - Powering the Growth of the Indian Economy

The GST implementation in India marks a major milestone in the tax reform journey of the country. By replacing multiple central and state-level indirect taxes, GST has simplified the tax structure, created a unified national market and reduced the cascading effect of taxes. It has brought significant benefits, including greater ease of doing business, enhanced competitiveness and stronger tax compliance.While challenges remain, such as limited cross-utilisation of credits, reduced fiscal autonomy for states, and potential revenue impacts for manufacturers. However, the overall impact of GST has been transformative, significantly outweighing these drawbacks and laying a strong foundation for a more robust and efficient taxation system in India.If you run a business, calculate your liability using the GST calculator and pay the applicable taxes.
