India’s Boldest GST Reform Since 2017

On India’s 78th Independence Day, Prime Minister Narendra Modi unveiled a sweeping proposal to overhaul the Goods and Services Tax (GST). The government plans to merge the four existing slabs 5%, 12%, 18%, and 28% into just two rates: 5% and 18%.


In addition, a 40% “sin tax” will be levied on products such as tobacco, pan masala, aerated drinks, and ultra-luxury cars. The Finance Ministry is preparing a detailed roadmap, with the GST Council set to deliberate and finalize the changes in upcoming sessions.


Why the Reform Matters

Introduced in July 2017 as the “One Nation, One Tax” regime, GST was meant to streamline India’s indirect taxation. However, multiple slabs led to confusion, compliance burdens, and frequent disputes over classification.

The new proposal addresses these concerns:


  • Simplification : Two-slab GST makes compliance easier for businesses, especially MSMEs.

  • Revenue Neutrality : The 40% sin tax is designed to offset revenue losses from scrapping the 28% slab.

  • Fairness : Essentials will remain taxed at 5%, protecting households from inflation shocks.

  • Global Alignment : Most countries operate with one or two GST/VAT rates, making India’s system globally competitive.



Industry & Market Reactions
  • FMCG Companies : Welcome simplification but seek clarity on products currently taxed at 12%, which may move up to 18%.

  • Auto & Luxury Goods : Ultra-luxury cars, premium liquor, and tobacco products face steeper taxes under the 40% sin tax.

  • MSMEs : Likely beneficiaries of reduced compliance complexity and litigation risks.

  • Stock Market : Consumer and retail stocks showed mild gains, while tobacco and liquor counters came under pressure amid tax hike fears.


Broader Economic Implications

If implemented, the GST reform could:

  • Boost Ease of Doing Business by lowering compliance hurdles.

  • Enhance Tax Buoyancy by minimizing disputes and broadening the base.

  • Impact Inflation in categories moving from 12% to 18%.

  • Improve Investor Confidence with a stable, globally aligned tax regime.



Expert Commentary

Tax professionals and economists hailed the proposal as a historic reform.

“The move to two GST slabs will significantly cut disputes and improve compliance. But ensuring revenue neutrality will be crucial, given states’ heavy dependence on GST collections,” said a leading tax expert.

Economists noted that while the sin tax is politically popular, it could spark inflation in select categories and trigger resistance from affected industries.


The Final Word

India’s proposal to shift to a two-slab GST with a 40% sin tax marks the boldest reform of the indirect tax system since 2017. If executed carefully, it can simplify taxation, reduce litigation, and boost business confidence. However, the final design especially around revenue balance and sectoral impact will depend on upcoming GST Council deliberations.
