A government shutdown isn't a decision anyone makes. It's what happens automatically when Congress can't agree on how to fund the government.
01Congress must fund the governmentEvery fiscal year, Congress needs to pass appropriations bills (or a stopgap "continuing resolution") to authorize government spending for agencies and programs.
02Funding expires without a dealIf those bills don't pass before the previous funding expires (usually September 30), there's a funding lapse, meaning no legal authority to spend on many operations.
03The law forces a shutdownUnder the Antideficiency Act, government agencies are prohibited from spending money without an appropriation. That law forces the government to shut down non-essential functions during a funding gap.
04Politics drives the deadlockShutdowns usually happen when parties clash over budget priorities, including what gets cut, what gets expanded, and how much to spend. These fights often include policy demands tied to funding, so it isn't just about dollars, it's also politics.
During a shutdown, “essential” employees (like TSA, military, and law enforcement) keep working but don't get paid until funding is restored. “Non-essential” employees are sent home without pay.
