What Is a Government Shutdown?

A government shutdown occurs when Congress fails to pass appropriations legislation or a continuing resolution to fund federal government operations, resulting in a lapse in funding that forces many federal agencies to cease non-essential functions. During a shutdown, essential services such as national defense, law enforcement, air traffic control, and Social Security payments continue, but many other government functions are suspended. Federal employees who are deemed non-essential are furloughed without pay, while essential employees continue working but may not receive paychecks until funding is restored. Government shutdowns have occurred with increasing frequency in recent decades, driven by partisan disagreements over spending levels, policy riders, and debt ceiling disputes. Notable shutdowns include the 16-day shutdown in October 2013, the 35-day shutdown from December 2018 to January 2019 — the longest in U.S. history — and several shorter funding lapses. Shutdowns carry real economic costs and disrupt government services, making their resolution a frequent source of political pressure on both parties.
