The U.S. federal government shutdown began on October 1, 2025, due to a failure in Congress to pass a funding bill for the 2026 fiscal year. As a result, many government agencies and programs have either partially or fully ceased operations. Government Agencies and Services That Will Shut Down or Be Furloughed:

• Non-essential federal employees in many agencies are being furloughed without pay, including food inspectors, park rangers, and most Small Business Administration staff (about 24% furloughed).
• The National Institutes of Health (NIH), Centers for Disease Control and Prevention (CDC), and Women, Infants, and Children (WIC) nutrition program are facing partial or full operational suspensions.
• The Environmental Protection Agency's efforts like drinking water contaminant cleanup and the U.S. Food and Drug Administration's food safety inspections will be limited or delayed.
• The Occupational Safety and Health Administration (OSHA) will have limited workplace inspections.
• Student loan services and some housing assistance services will be disrupted.
• The federal judiciary warns that courts might run out of funds within days, potentially halting court operations.
• Some FEMA projects are limited due to funding constraints, though emergency response efforts continue.
• The Small Business Administration will stop new loan approvals and several business development programs will halt.

Agencies and Services Remaining Open:

• Essential functions and employees will remain active, such as FBI and CIA agents working without pay, military personnel, border patrol agents, customs officers, and National Guard forces.
• The Social Security Administration will continue to provide disability and retirement benefits but will furlough about 12% of its workforce.
• Medicare and Medicaid will continue due to mandatory funding.
• U.S. Postal Service will continue operations as it is self-funded.
• Air traffic controllers and most Transportation Security Administration (TSA) employees will remain on duty.
• Criminal enforcement by the Bureau of Alcohol, Tobacco, Firearms, and Explosives will continue, though permit processing will stop.

This shutdown impacts roughly 900,000 furloughed federal employees and approximately 700,000 who continue working without pay. The shutdown will last until Congress passes new appropriations legislation to fund government operations. These details provide a comprehensive picture of which agencies shut down or remain functional during the current government shutdown in October 2025.
