Each year Congress must decide how much money federal agencies are allowed to spend. That decision runs through the appropriations process, one of the oldest and most consequential powers the Constitution gives the legislative branch. Understanding how FY2026 appropriations work helps explain why funding deadlines, continuing resolutions and shutdown threats appear in the news so often.
The Power of the Purse
Article I of the Constitution states that no money may be drawn from the Treasury except through appropriations made by law. In practice, this means that even after a program is authorized, agencies cannot spend money until Congress passes a separate bill granting the funds. This division between authorization and appropriation is a deliberate check, ensuring elected lawmakers revisit spending decisions regularly.
The Twelve Annual Funding Bills
Discretionary federal spending is normally divided among twelve regular appropriations bills, each covering a cluster of agencies and programs. These include measures for areas such as Agriculture; Commerce, Justice and Science; Defense; Energy and Water Development; Homeland Security; the Interior and Environment; Labor and Health and Human Services; the Legislative Branch; Military Construction and Veterans Affairs; and others. Each bill moves through subcommittee, full committee, floor votes in both chambers, and eventually a reconciliation of House and Senate differences before heading to the president.
Completing all twelve bills on time is difficult, and Congress frequently bundles several into larger packages or relies on stopgap measures to keep agencies open while negotiations continue.
Continuing Resolutions and the Fiscal Calendar
The federal fiscal year begins on October 1. When lawmakers cannot finish the appropriations bills by that date, they typically pass a continuing resolution, often shortened to CR. A continuing resolution extends funding at existing levels for a set period, buying time without setting new policy. CRs are common, but they are widely viewed as a stopgap rather than a substitute for full-year appropriations, because they make long-term planning harder for agencies.
What Happens at a Funding Deadline
If funding for an agency lapses and no appropriation or continuing resolution is in place, that part of the government enters a shutdown. During a shutdown, non-essential operations pause and many federal employees are furloughed, while essential functions tied to safety and security continue. Shutdowns can be partial, affecting only the agencies whose bills have not been enacted, while fully funded departments keep operating normally.
For fiscal year 2026, Congress enacted some of the regular bills while extending others through continuing resolutions, producing a mix of completed and pending funding measures over the course of the year. This patchwork approach is typical when negotiations over contested items stretch past the start of the fiscal year.
Spending Caps and Their Limits
Discretionary spending has at times been constrained by statutory caps designed to limit growth in federal outlays. When those caps lapse or stop being binding, the negotiation over top-line spending levels becomes more open-ended, increasing the importance of the bargaining between the chambers and the White House. The size of the overall discretionary total often becomes one of the central disputes in any appropriations cycle.
Why the Process Matters
The appropriations process is where broad policy goals meet concrete numbers. It determines staffing at federal agencies, funding for research and infrastructure, support for states and localities, and the resources available for national defense. Because the process recurs every year and carries hard deadlines, it is also one of the few moments when divided branches of government are forced to negotiate directly.
For citizens, following appropriations offers a clearer view of governing priorities than almost any campaign speech. The bills reveal, in dollars, what the federal government chooses to fund and what it does not.
The Bottom Line
The FY2026 appropriations cycle illustrates a recurring tension in American government: a constitutional system that requires regular, deliberate funding decisions, paired with a political environment that often pushes those decisions to the brink of deadlines. Continuing resolutions, partial shutdowns and last-minute packages are not anomalies; they are the visible symptoms of a process that demands agreement from many actors before any money can be spent.
