An annual budget that includes income and expenses for ongoing operations is the Operating Budget of the government.
Explanation:
In order to carry out its own expenses, the government needs to devise well in advance the provisions that are needed to be done for the said expenses.
In order to determine the means through which the revenue for these expenses is to be fetched, the government prepares an operating budget and presents it in front of the houses.
This budget is different than the national budget of the country.
