GST Rationalisation in India: A Simpler Path to Growth

When the Goods and Services Tax (GST) was introduced in July 2017, it was hailed as India’s biggest indirect tax reform since Independence. By replacing a patchwork of state and central levies with a unified structure, GST promised to embody the vision of “One Nation, One Tax.” It streamlined compliance, improved transparency, and expanded India’s tax base. From 66.5 lakh registered taxpayers in 2017, the number has grown to more than 1.5 crore by 2025, while monthly GST collections have risen from around ₹82,000 crore in 2018 to over ₹2 lakh crore today.

Although things improved, the GST system wasn't perfect. The four different tax rates (5%, 12%, 18%, and 28%) made things complicated, led to lobbying, and influenced what people bought. An additional problem was the inverted duty structure, where businesses paid a higher tax on raw materials than on their final products. This led to frustrating delays in getting tax refunds and caused a cash crunch for businesses. It was clear the GST needed a major overhaul. 

That overhaul, now informally called GST 2.0, arrived on September 3, 2025, when the 56th GST Council meeting approved sweeping reforms.

The core of the reform lies in rationalising the slab structure:

• Merit Rate (5%) – for essentials and mass consumption goods.

• Standard Rate (18%) – for most goods and services.

• Demerit Rate (40%) – for luxury and sin goods such as tobacco, high-end cars, and sugary drinks.

In effect, India has moved from a confusing four-slab regime to a much simpler two-slab system with one special category. Alongside this, many goods and services have been reclassified, some completely exempted, and certain cesses abolished.

This restructuring, effective from September 22, 2025, is nothing short of transformational. It marks a decisive shift toward simplicity, transparency, and consumption-led growth.

GST 2.0 was shaped by a mix of industry pressure, political needs, and global conditions. Businesses in sectors like FMCG, textiles, and automobiles had long demanded simplification, arguing that multiple slabs and refund delays distorted pricing and strained liquidity. Politically, the government grew more confident as the tax base expanded and compliance improved, while easing inflation also carried electoral importance. Macroeconomic factors added urgency, with global trade tensions making domestic demand India’s strongest growth lever. International experience too offered guidance, as countries like Australia and Canada rely on simpler GST or VAT structures. India’s two-slab model with a demerit category reflects these lessons while accommodating its own realities.

The impact of GST 2.0 has been felt across sectors in diverse ways. Many everyday items like soaps, shampoos, toothpaste, bicycles, and packaged foods now have a lower tax, which means they're cheaper to buy. This helps both consumers and companies, as more people are buying these products. 

Big-ticket electronics and appliances like televisions, refrigerators, and air conditioners are also more affordable since their tax rate dropped from 28% to 18%. This is expected to boost sales and consumer demand. The housing market is also getting a big boost. The tax on cement has dropped from 28% to 18%, and other construction materials like marble, granite, and bricks are now taxed at just 5%. This makes it cheaper to build homes, which should encourage more people to buy them, especially in rural areas. 

The automobile industry is also set to improve, with lower taxes on small cars, two-wheelers, and commercial vehicles (from 28% to 18%), making them more accessible to buyers. Farmers, who are crucial to the Indian economy, are also seeing benefits. The tax on things they need to do their work, such as tractors, irrigation equipment, and fertilizer, has been reduced. This directly helps them save money and increases their income.

Perhaps the most socially significant reforms are in education and healthcare. Exercise books, pencils, crayons, and a set of thirty-three life-saving drugs have been exempted from GST altogether. Traditional medicines such as Ayurveda and homeopathy now attract only 5 percent, while health and life insurance premiums are exempt, easing household budgets and strengthening India’s social safety nets. Renewable energy has also received a boost, with solar modules and wind turbine generators becoming cheaper, lowering generation costs and aligning with India’s green energy targets. On the other hand, not all sectors have gained. Oil and gas, for instance, have seen GST rise from 12 to 18 percent, raising production costs and potentially discouraging investment in upstream projects.

Beyond rate changes, GST 2.0 has brought significant compliance reforms. Low-risk businesses now receive GST registration within three working days, exporters are promised automated refunds within a week, and new GST Appellate Tribunals have been operationalised to reduce a backlog of over 40,000 cases. A digital-first filing system has been introduced, particularly benefiting MSMEs and startups. These changes are expected to reduce compliance burdens and broaden the formal tax base, which is vital for revenue stability in the long run.

While GST 2.0 has been welcomed, it is not free from criticism. A major concern is the projected revenue loss of around ₹48,000 crore, which could strain government finances and put pressure on states dependent on GST compensation. Sectoral disparities also remain, with oil and gas facing higher costs and premium clothing attracting a steeper 18 percent rate, potentially discouraging investment and hurting demand. Critics further argue that the two-slab system may burden middle-class households, as the jump from 5 to 18 percent does not fully account for income differences. Implementation, too, is expected to pose hurdles, with smaller traders likely to struggle with reclassification and compliance. Finally, some caution that the demand boost may be temporary, as long-term gains depend on employment and income growth rather than cheaper consumer goods.

In the immediate term, GST 2.0 is expected to create a revenue gap, with government finances facing an estimated shortfall of around ₹48,000 crore. However, policymakers remain optimistic that stronger consumption, improved compliance, and steady long-term growth will gradually offset this loss. By reducing taxes on essentials and consumer durables, the reform increases disposable incomes and stimulates demand, particularly in sectors such as FMCG, healthcare, and automobiles, which analysts believe could record double-digit growth in the coming year.

At the same time, GST rationalisation is likely to play a role in containing inflation. Lower rates on mass-consumption goods are expected to ease price pressures, even as global oil market volatility continues to pose risks. Looking ahead, despite external trade headwinds, domestic demand is projected to remain a key growth driver. Agencies such as ICRA forecast that India’s GDP growth in FY2026 will hold steady at around 6.5 percent, underscoring the potential of GST reform to balance growth momentum with macroeconomic stability.

The rationalisation of GST in 2025 marks a historic leap in India’s economic journey. By collapsing multiple slabs into a simpler structure, easing compliance, and making essentials more affordable, GST 2.0 addresses many of the pain points of its predecessor.

More importantly, it aligns taxation with the aspirations of a Viksit Bharat 2047,a developed India that is inclusive, competitive, and growth-oriented.

That said, GST 2.0 is not a magic bullet. Revenue risks, sectoral challenges, and implementation hurdles remain. The success of these reforms will depend on how policymakers manage the trade-offs and whether businesses and consumers fully embrace the new regime.

The story of GST is far from over. But with GST 2.0, India has taken a decisive step toward making taxation not just a tool for revenue collection, but a catalyst for development.
