The United States budget process begins when the President of the United States submits a budget request to Congress. The President 's budget is formulated over a period of months with the assistance of the Office of Management and Budget (OMB), the largest office within the Executive Office of the President. The budget request includes funding requests for all federal executive departments and independent agencies. Budget documents include supporting documents and historical budget data and contains detailed information on spending and revenue proposals, along with policy proposals and initiatives with significant budgetary implications. The President 's budget request constitutes an extensive proposal of the administration 's intended revenue and spending plans for the following fiscal year. The budget proposal includes volumes of supporting information intended to persuade Congress of the necessity and value of the budget provisions. In addition, each federal executive department and independent agency provides additional detail and supporting documentation on its own funding requests. The documents are also posted on the OMB website.
