NEW DELHI: Amid record-high fuel prices, finance minister Nirmala Sitharaman on Monday said there is no proposal as of now to bring crude oil, petrol, diesel, jet fuel (ATF) and natural gas under the Goods and Services Tax (GST).This meant that the central government continued to levy excise duty on them while state governments charged VAT. These taxes, with excise duty, in particular, have been raised periodically.
