In a series of tweets, the former finance minister said the bonanza to central government is Rs 25 on every litre of petrol and this money rightfully belongs to the average consumer.
"Central government saves Rs 15 on every litre of petrol due to fall in crude oil prices. Central government puts additional tax of Rs 10 on every litre of petrol."
"It is possible to cut up to Rs 25 per litre, but the government will not. They will cheat the people by cutting price by Rs 1 or 2 per litre of petrol," he said on Twitter.
More than a week after state-owned oil firms ended a 19-day pre-Karnataka poll hiatus on revising fuel prices, petrol and diesel rates have touched record highs.
Petrol costs Rs 76.87 per litre in Delhi and diesel costs Rs 68.08 a litre. In the last nine days, petrol price has risen by Rs 2.24 a litre and diesel by Rs 2.15.
Rates vary from state to state depending on the incidence of local sales tax or VAT. The prices in Delhi are the cheapest among all metros and most state capitals.
The central government levies Rs 19.48 a litre of excise duty on petrol and Rs 15.33 per litre on diesel.
In Delhi, VAT on petrol was Rs 15.84 a litre, and Rs 9.68 on diesel in April. Now, it is Rs 16.34 on petrol and Rs 10.02 a litre on diesel.
Every rupee cut in excise duty on petrol and diesel will result in a revenue loss of Rs 13,000 crore.
The government had raised excise duty nine times between November 2014 and January 2016 to shore up finances as global oil prices fell, but then cut the tax just once in October last year by Rs 2 a litre.
Subsequent to that excise duty reduction, the Centre had asked states to also lower VAT. Just four of them -- Maharashtra, Gujarat, Madhya Pradesh and Himachal Pradesh -- reduced rates while others including BJP-ruled ones ignored the call.
In all, duty on petrol rate was hiked by Rs 11.77 per litre and that on diesel by 13.47 a litre in those 15 months that helped governments excise mop up more than double to Rs 2,42,000 crore in 2016-17 from Rs 99,000 crore in 2014-15.
