<h1>Petrol and Diesel May Come Under GST at 28% Peak Rate; States Can Levy Extra Taxes to Maintain Prices.</h1> The inclusion of petrol and diesel under the Goods and Services Tax (GST) in India will involve a peak tax rate of 28%, with states allowed to impose additional taxes to maintain current retail prices. Bihar's Deputy Chief Minister indicated that this change will take time due to differing state opinions. Currently, states derive 45-50% of their tax revenue from these fuels. The existing tax incidence on petrol and diesel, which includes central excise duty and state VAT, ranges from 35-50%. The GST Council will decide on the timing of this inclusion, with a focus now on implementing a new return filing system.
