Telecom, banks, pharmaceuticals, services and consumer discretionary-related may face some heat with the passage of Goods and Services Tax (GST) as the current tax rate may go up to 18 per cent from 15 per cent if the indirect tax bill is passed. According to market experts, telecom companies such as Bharti Airtel, Idea Cellular and Reliance Communications may see marginal dip in consumption after the rise in tax rates. Quick service restaurants such as Jubilant FoodWorks, Coffee Day Enterprises and Westlife Developments may also come under pressure if GST Bill is implemented. According to Chandan Taparia, analyst, Anand Rathi Financial Services, "Jubilant FoodWorks, Coffee Day Enterprises and other restaurant business will suffer with the passage of GST." Jubilant FoodWorks and Coffee Day Enterprises shares were trading over 4 per cent and 1 per cent down (at 12.55 pm) on Wednesday ahead of the introduction of the GST Bill in the upper house of Parliament today around 2 pm. Taparia further added that GST will be negative for milk, butter, ghee, edible and coconut oil related companies such as Parag Milk Foods and KMG Milk Foods. Market experts do not see an sudden spike in the short run if GST Bill will be cleared this time. Arun Gopalan, vice president, research and investments at Systematix Shares said, "Optimism over GST Bill have already sent markets at higher levels. Hence, we can an euphoric rise in the markets in the short run. However, the passage will be positive for markets in the longer term." Gaurav Dua, head of research, Sharekhan said, "GST will impact truck sales in India as it will reduced the time spent by trucks at checkpoints. Hence, companies like Ashok Leyland and Tata Motors may also be impacted with GST. Telecom companies will also be impacted."
