The Indian government is considering a significant overhaul of the Goods and Services Tax (GST) structure by scrapping the 12% and 28% slabs and consolidating most products into the 5% and 18% categories. Additionally, certain luxury and sin goods may be moved into a new 40% slab. This reform is part of the broader agenda to simplify the indirect tax system, boost domestic consumption, and provide relief to Micro, Small, and Medium Enterprises (MSMEs) that form the backbone of the Indian economy.

The Reform in Detail
Since the rollout of GST in 2017, India has operated on a multi-slab structure—0%, 5%, 12%, 18%, and 28%, along with cess on specific luxury and sin products. While it was meant to rationalize taxation, multiple slabs often led to confusion, litigation, and compliance challenges.
By eliminating the 12% and 28% slabs, the government is attempting to create a simpler, three-tier GST system:
- 5% slab: For essential goods and services.
- 18% slab: For most products and services.
- 40% slab: For luxury and sin goods such as tobacco, alcohol, and high-end vehicles.
This shift is expected to reduce classification disputes, cut compliance costs, and improve ease of doing business, particularly for MSMEs.
Impact on Consumers and MSMEs
- Cheaper Essential Goods: With many items moving from 12% to 5%, everyday essentials, household goods, and mass-consumption products could see a price reduction, spurring higher consumption.
- Stability in Mid-Range Goods: Products currently taxed at 18% may largely remain unaffected, ensuring stability for industries like FMCG, electronics, and retail.
- Costlier Luxury Consumption: Items moving from 28% to 40% will become more expensive, discouraging consumption of luxury and sin goods while increasing government revenue.
- Relief to MSMEs: Reduced complexity and fewer slabs will bring greater clarity in invoicing, compliance, and working capital management, providing relief to small manufacturers and traders.
Implications for the Indian Share Market
The GST rationalization will have both sectoral winners and losers, influencing stock market sentiment:
- Positive for FMCG & Consumer Durables: Companies like Hindustan Unilever, ITC, Dabur, Godrej Consumer, and Marico are likely to benefit as reduced GST on essentials could drive volume growth and expand rural demand.
- Boost for Retail & E-commerce: Firms like DMart, Trent, Avenue Supermarts, and e-commerce giants could gain from higher consumption levels, especially in discretionary categories that shift to the 5% slab.
- Encouragement for MSME-focused companies: Listed small and midcap firms in manufacturing, textiles, auto ancillaries, and packaging may witness improved profitability and cash flow.
- Luxury & Sin Goods May Face Pressure: Cigarette, liquor, and premium automobile makers could see demand pressure if taxation moves up to 40%. This may impact ITC (cigarettes segment), United Spirits, United Breweries, and luxury auto companies like M&M’s premium segment, Tata Motors (Jaguar Land Rover), and imported car brands.
- Stock Market Sentiment: Broader markets are likely to react positively due to the consumption boost and MSME relief, making consumer, retail, and midcap manufacturing sectors attractive. However, selective correction in luxury/sin goods stocks could balance the impact.
The proposed GST reform is one of the most ambitious steps since its introduction in 2017. By eliminating the confusing mid-level slabs and introducing a streamlined structure, the government aims to boost consumption, simplify taxation, and support MSMEs. While luxury segments may face a short-term hit, the overall economy could benefit from higher demand and improved ease of doing business.
