The volume of petrol and diesel dipped to 43 per cent in April, during the lockdown, but has since doubled up to 85 per cent in June and 83 per cent in July, it said, adding if economic activity rebounds to pre-pandemic levels by November, the annual volume decline will be restricted to 11-12 per cent in FY21.
Its director Ankit Hakhu explained the role played by the higher excise duty and its importance in the revenue arithmetic.
Central excise duty was raised in March and May 2020. An increase in excise duty increases the taxable value of petrol and diesel for the levy of state sales tax. This higher taxable value of the fuel is providing additional sales tax of Rs 3 per litre to states on a weighted average basis," he said.
