CBO’s Director, Phillip Swagel, testifies before the Senate Appropriations Committee’s Subcommittee on the Legislative Branch.

Throughout the reconciliation process, CBO, in collaboration with the staff of the Joint Committee on Taxation, assists the Congress by providing nonpartisan analysis and cost estimates for legislative proposals.

CBO estimates that plans for U.S. nuclear forces, as described in the fiscal year 2025 budget and supporting documents, would cost $946 billion over the 2025–2034 period, $190 billion more than CBO's 2023 estimate for the 2023–2032 period.

CBO's transparency efforts are intended to promote a thorough understanding of its work, help people gauge how estimates might change if policies or circumstances differed, and enhance the credibility of its analyses and processes.

CBO provides an overview of federal tax credits that support investment in wind and solar electric power. The agency also explains how it assesses the credits’ budgetary and economic effects and how its baseline reflects JCT’s revenue estimates.

CBO requests appropriations of $75.8 million for fiscal year 2026. The requested amount is an increase of $5.8 million, or 8.2 percent, above the funding provided this year.
