The Buget of the United States Government is a federal document that the President submits to the U.S. Congress. The President's budget submission outlines funding recommendations for the next fiscal year, which begins on October 1st. Congressional decisions are governed by rules and legislation regarding the federal budget process. House and Senate Budget committees each develop budget resolutions, which provide spending limits for the House and Senate Appropriations Committees' subcommittees, which then approve individual appropriations bills to allocate funding to various federal programs. After Congress approves an appropriations bill, it is sent to the President, who may sign it into law, or may veto it. A vetoed bill is sent back to Congress, which can pass it into law with a two-thirds majority in each chamber. Congress may also combine all or some appropriations bills into an omnibus reconciliation bill. In addition, the President may request and the Congress may pass supplemental appropriations bills or emergency supplemental appropriations bills.
