Why Does the Government Keep Shutting Down?
A shutdown happens when Congress misses its own deadline for the quarter of federal spending it has to approve every year. Here is what actually stops, why the deadline keeps getting missed, and what would have to change for it to stop happening.
Updated September 13, 2026 · 4 min read · An independent project; the site’s own view is marked where it appears.
The Constitution says no money may be drawn from the Treasury except under an appropriation made by law.1 Most federal spending, about 73 percent in fiscal 2025, is set by permanent law: Social Security, Medicare, Medicaid, interest on the debt. The other 27 percent, from the military to the national parks to the staff who answer the phones, is approved one year at a time, in twelve bills, and the year begins October 1.2
When October 1 arrives with no bill, Congress usually passes a continuing resolution, a stopgap that keeps last year's money flowing for a few weeks or months. A stopgap does not finish anything; it moves the deadline. When even the stopgap fails, a 19th-century law called the Antideficiency Act, as the executive branch has read it since 1980, requires agencies to stop everything except work that protects life and property.3 5 That is a shutdown.
- Keeps going: Social Security and Medicare payments, which run under permanent law.13 Applying for benefits and appeals continue too, though during the 2025 lapse field offices stopped issuing benefit verification letters and replacement Medicare cards in person.14
- Keeps going, unpaid: air traffic control, border protection, federal law enforcement, and other work that protects life and property.5
- Stops: most everything else in the affected agencies. Employees are sent home. Since 2019 they are guaranteed back pay once the lapse ends; contractors' employees are not.16
- Not the same thing: the debt limit, which is a separate fight over the Treasury's authority to borrow for bills already incurred.13
Congress last passed all of its spending bills before October 1 for fiscal year 1997. It has needed a stopgap in every year since, about five a year, and agencies have spent an average of 118 days a year running on them.4 6 The two most recent lapses were both records: 43 days for the whole appropriated government in late 2025, in a fight over expiring health-insurance credits, and 76 days for the Department of Homeland Security alone in early 2026, in a fight over immigration enforcement.7 8 10 11 The Congressional Budget Office projected, under its six-week scenario, that the 2025 shutdown would permanently cost about $11 billion in output.9
The deadline survives because it is useful. It is the one moment when a minority can force a negotiation about something else, and when a majority can dare the other side to close the government rather than accept a clean bill. The costs land on people outside the room: employees who wait for pay, contractors who never get it, and a public that loses services. Missing the date carries no automatic consequence for the people who miss it. That is an observation about incentives, not about anyone's motives, and both parties have used the deadline when it suited them.
The obvious fix is to make funding automatic: if the bills are not done by the deadline, last year's money continues under a neutral formula, so there is no shutdown and no hostage. Versions of that idea have bipartisan sponsors in the Senate.15 The standard objection, made by senior appropriators of both parties, is that removing the deadline removes the only pressure to finish the bills, so the budget drifts onto autopilot: last year's numbers roll forward, new priorities never get funded, and control over spending shifts toward whichever administration is executing stale accounts.19 The reply is that the deadline has been missed for 29 straight years, so the pressure it supplies is mostly pressure for a bargain about something else.
Shutdowns are the clearest example of what this site calls a rule with no consequence: the public pays for a missed deadline and the people who missed it do not. The three-minute case shows how that same pattern shows up in two other places and what would change it.

- September 13, 2026. Corrected the first version: only the roughly one quarter of federal spending that is appropriated annually is at stake in a lapse, not the whole government; the $11 billion figure is CBO's six-week scenario projection; Social Security applications and payments continued during the 2025 lapse while some in-office services stopped; the Prevent Government Shutdowns Act has 24 cosponsors, not 22.
- September 13, 2026. Reframed the page as an answer to the question in its title. Cut the chronology, the full what-stops table, the number tiles, the standalone objection section, and the scorecard box; kept the objection inside the explanation; moved the site's proposal into one labeled panel. The research behind the removed material is retained in the project's editorial notes.
