Interim Budget

Context (IE): An Interim budget is presented by the Finance Minister.
An Interim Budget is a temporary financial plan covering government expenses until a new government takes over at the central level.
It seeks parliamentary approval for 4 months’ expenses, including salaries and ongoing programs, without tax changes.
It is presented when there is insufficient time for Parliament to approve various grants and debate changes in taxation before the fiscal year begins.
It’s widespread in election years, allowing the new government to present a full budget.

A Vote-on-account, a part of the Interim Budget, usually lasts for two months and outlines provisional government expenses (1/6^th of the total estimation) until a new government is formed.
The Vote on account can be approved within the framework of Interim budget.
R K Shanmugam Chetty presented Independent India’s first vote on account in 1948.
