In case the Budget is not passed by 1st April, the government can request a Vote on Account from Parliament. This allows the government to withdraw funds from the Consolidated Fund of India for its routine functioning until the budget is passed. The Vote on Account is typically valid for two months, after which the full budget is expected to be approved. It is different from the Supplementary Grant, which is sought when additional funds are required after the approval of the budget.
