New Delhi: The proposed 4-tier Goods and Services Tax (GST) structure may hit the common man as it is likely to result in higher taxes on various items including kitchen staples such as edible oils, spices and chicken. The prices of certain consumer durables like televisions, air conditioners, fridges and washing machines may however become cheaper with a decrease in taxes. The government plans to roll out the new indirect tax regime, GST, from April 1, 2017. In its meeting with states this week, the Centre has proposed a four slab GST rate structure.
