Few topics generate more headlines and more confusion than the federal budget. Shutdowns, continuing resolutions, the debt ceiling — they sound interchangeable but are completely different things. This course untangles how the government decides what to spend, and what happens when it can’t agree.
Two separate steps: authorize, then appropriate
Federal spending takes two distinct acts of Congress. An authorization creates or continues a program and sets a ceiling on what it may spend. An appropriation actually provides the money. A program can be authorized and still go unfunded — which is why "authorized to be appropriated" in a bill is a promise, not a check.
New to bill text? The Reading a Bill course covers how to spot these clauses.
The fiscal year and the twelve bills
The federal fiscal year runs from October 1 to September 30. Each year Congress is supposed to pass twelve appropriations bills funding the different parts of government — defense, agriculture, and so on — before October 1.
In practice it rarely finishes on time, which sets up the drama below.
Continuing resolutions and shutdowns
When Congress can’t pass the appropriations bills by the deadline, it has two options:
- Pass a continuing resolution (CR)A stopgap that keeps the government funded at existing levels for a set time, buying more time to negotiate.
- Or trigger a shutdownIf neither full appropriations nor a CR passes, funding lapses. Non-essential operations stop and many federal workers are furloughed until Congress acts.
Mandatory vs. discretionary spending
Not all spending runs through the annual appropriations fight:
- Mandatory spending — programs like Social Security, Medicare, and Medicaid, funded automatically by standing law. It is the majority of the budget and is not set by the yearly appropriations bills.
- Discretionary spending — the part Congress sets each year through appropriations, including defense and most agencies.
The debt ceiling
The debt ceiling is a legal cap on how much the federal government can borrow to pay obligations it has already incurred. Raising it does not authorize new spending; it lets the Treasury pay bills Congress already approved. If the ceiling is not raised in time, the government risks default, with potentially severe economic consequences.
Frequently asked questions
What is the difference between a government shutdown and the debt ceiling?
A shutdown happens when Congress fails to fund the government, causing a lapse in spending. The debt ceiling is a cap on borrowing to pay obligations already incurred; failing to raise it risks default. They are different problems with different consequences.
What is a continuing resolution?
A temporary funding measure that keeps the government running at current levels when Congress has not passed full appropriations on time, avoiding a shutdown.
Why is most of the budget not debated each year?
Because the largest share is mandatory spending — programs like Social Security and Medicare funded automatically by standing law, outside the annual appropriations process.
