The Goods and Services Tax (GST) department in Mumbai has proposed a hike in the tax on liquor served in restaurants and hotels below 3 stars, from 5% to 10-15%. This could help the government increase revenue by ?300 to ?600 crore annually. The department has also proposed an increase in tax on gold and gold jewellery, as well as uniformity in tax on fabric and readymade garments. No decision has been made by the government on these proposals.
