Government shutdowns tend to occur when there is a disagreement over budget allocations before the existing cycle ends. After it passes both chambers, it proceeds to the President of the United States to sign the bill into law. The finalized version of the bill is then voted upon by both the House of Representatives and the Senate. Congress begins this process through proposing an appropriation bill aimed at determining the levels of spending for each federal department and government program. Under the separation of powers created by the United States Constitution, the appropriation and control of government funds for the United States is the sole responsibility of the United States Congress. During the 2013 shutdown, Standard & Poor's, the financial ratings agency, stated on October 16 that the shutdown had "to date taken $24 billion out of the economy", and "shaved at least 0.6 percent off annualized fourth-quarter 2013 GDP growth".

Shutdowns also cause a significant reduction in economic growth (depending on the length of the shutdown). A major loss of government revenue comes from lost labor from furloughed employees who are still paid, as well as loss of fees that would have been paid during the shutdown. Shutdowns cause the disruption of government services and programs, including the closure of national parks and institutions (in particular, due to shortages of federal employees). history have included the 21-day shutdown of 1995–1996 during the Bill Clinton administration over opposition to major spending cuts the 16-day shutdown in 2013 during the Barack Obama administration caused by a dispute over implementation of the Affordable Care Act (ACA) and the 35-day shutdown of 2018-2019 during the Donald Trump administration, the longest shutdown in US history, caused by a dispute over the funding amount for an expansion of the U.S.–Mexico border barrier. Some of the most significant shutdowns in U.S. This opinion was not consistently adhered to through the 1980s, but since 1990 all funding gaps lasting longer than a few hours have led to a shutdown. Prior to 1980, funding gaps did not lead to government shutdowns, until Attorney General Benjamin Civiletti issued a legal opinion requiring the government to be shut down when a funding gap occurs. Since the enactment of the US government's current budget and appropriations process in 1976, there have been a total of 22 funding gaps in the federal budget, ten of which have led to federal employees being furloughed.
