What agency is primarily tasked with providing budgetary information to Congress?

The agency primarily tasked with providing budgetary information to Congress is the Congressional Budget Office (CBO). The CBO plays a crucial role in the federal budget process by providing nonpartisan analysis to inform Congress regarding the economic and budgetary effects of proposed legislation. It produces reports that project the cost of legislation and its impact on the federal budget, thus helping lawmakers in their decision-making processes about spending and taxation.

The CBO is particularly important during the budget cycle as it prepares baseline budget projections and analyzes the budgetary implications of policy proposals. This function is vital as it ensures that Congress has reliable information when evaluating budgetary decisions, contributing to a transparent and informed legislative process.
