The "Government Shutdown Prevention Act of 2025" aims to prevent federal government shutdowns by establishing an automatic continuing appropriations process. This mechanism would activate if Congress fails to enact regular appropriation bills for a new fiscal year, ensuring that government programs, projects, and activities can continue operating without interruption. Under this bill, if no appropriation act is in effect, funds would automatically be provided at a rate of operations not exceeding 94% of the previous fiscal year's funding level for the first 90 days. To further incentivize timely appropriations, the funding rate would then decrease by an additional 1 percentage point for each subsequent 90-day period that a full appropriation bill remains unpassed, potentially extending beyond the current fiscal year. The bill specifies that funds for entitlements, other mandatory payments, and activities under the Food and Nutrition Act of 2008 would be provided at the rate necessary to maintain current program levels. All automatic appropriations would be subject to the terms and conditions of the preceding fiscal year, but it prohibits high initial rates of operation or complete distribution of funds to states or grantees that could preempt final funding decisions. This automatic funding would remain in effect until a regular appropriation bill for the fiscal year or a specific continuing resolution is enacted into law. The legislation is designed to ensure continuity of government services while applying increasing financial pressure on Congress to fulfill its constitutional duty of passing annual appropriations.
