Stop the Baseline Bloat Act of 2025

This bill proposes to amend the Balanced Budget and Emergency Deficit Control Act of 1985 , specifically targeting how the Congressional Budget Office (CBO) calculates its baseline projections for discretionary appropriations. The legislation seeks to modify the existing framework by introducing new exclusions to these critical budget forecasts. The central provision mandates that the CBO exclude resources designated as an emergency requirement and any funds provided through supplemental appropriations laws from its baseline projections. This aims to prevent temporary or extraordinary funding measures from inflating future budget baselines, thereby providing a more accurate long-term fiscal outlook. The bill's intent is to ensure that regular discretionary spending is not artificially increased by one-time or urgent allocations.
