Stop the Baseline Bloat Act of 2025

This bill changes how the Congressional Budget Office (CBO) projects future federal spending. It says that when CBO builds its “baseline” for discretionary spending, it must leave out money marked as emergency and money from one-time supplemental bills. In plain terms: one-time or emergency add-ons would no longer be treated like normal, ongoing spending in future estimates. The text amends the Balanced Budget and Emergency Deficit Control Act to make this change in the baseline rules.

Key points:

• Who is affected: Congress and federal agencies that rely on CBO’s budget projections; indirectly, taxpayers and communities that depend on federal programs.
• What changes: CBO’s baseline would exclude emergency-designated funds and supplemental appropriations, so future projections won’t assume those one-time funds continue every year.
• When: The change would take effect if the bill becomes law; the bill text directs an update to the baseline rules in the existing budget law.
