An interim budget, just like a full-year budget, is an annual financial statement of a government's finances.
It contains key details such as where money comes from (revenue) and where it is spent (expenditure), as well as projections of growth and fiscal position.
However, unlike a full-year budget, an interim budget covers a smaller period of time, usually few months.
An interim budget is created by an incumbent government before election.
This year, the general election - to elect a central government - is due by May, thus an interim budget.
