"I think that it (budget) is inevitable to be a game changer. Because this is the first full budget of this government...It has got full time therefore budget has to be different...And (I) hope the economy will revive," Sinha said during round table conference on 'Will the budget be a gamechanger' organised by Debating India Foundation.
"I think this time the biggest challenge for the Finance Minister (Arun Jaitley) is how do we revive the investment cycle in this economy," he said.
Referring to the GDP numbers released by Central Statistics Office, Sinha said there is a need for greater scrutiny of data provided by the government body.
As per the new data the 4.7 per cent growth rate for 2013-14 was revised to 6.9 per cent.
He also called for introduction of Direct Taxes code saying, "It is ready and cooked."
Jaitley is scheduled to present his first full fledged Budget on February 28.
