Estimate the Federal Budget
Federal budget data are obtained from the Public Budget Database of the White House Office of Management and Budget. Deficit, surplus, and debt figures are obtained from OMB's Historical Tables.
This is the President's proposed Federal Budget for the US government's fiscal year, which begins on October 1.
The President's budget is usually sent to Congress in February, for the fiscal year beginning the following October. In most years, this website is updated by the end of March. A change of administrations can delay the release of budget data by a couple of months.
