If you have been considering a second-hand electric vehicle (EV) or a smaller petrol or diesel car to save money, potentially, there can be a bump in your road. According to a few reports, the Goods and Services Tax (GST) Council, in its upcoming meeting, scheduled to be held on December 20-21 in Jaisalmer, Rajasthan, is expected to discuss a proposal that could hike GST on old and used EVs and smaller vehicles from 12 per cent to 18 per cent.
