What Does the House Appropriations Committee Do?

The House Appropriations Committee writes the 12 annual bills that decide how the federal government spends its discretionary money. Every dollar for the military, the FBI, national parks, NASA, federal courts, veterans’ hospitals, and hundreds of other agencies and programs has to pass through this committee before it can be spent. With 63 members spread across 12 subcommittees, it is the largest committee in the House and one of the most powerful bodies in Congress.¹

What the Committee Actually Controls

The committee’s authority comes straight from the Constitution. Article I, Section 9, Clause 7 says no money can be drawn from the Treasury except through appropriations made by law.² That is the “power of the purse.” The executive branch cannot spend a cent without explicit approval from Congress, and the Antideficiency Act reinforces the point by making it illegal for any federal officer or employee to obligate money that exceeds or lacks an appropriation.³

One important boundary: not all federal spending flows through this committee. The budget splits into two categories. Discretionary spending covers programs Congress must vote to fund every year, and that is the committee’s territory. Mandatory spending, which includes Social Security, Medicare, and Medicaid, runs on autopilot under permanent law and continues whether or not Congress passes a single appropriations bill. Changing those programs requires separate legislation through the authorizing committees. Mandatory spending is the majority of the federal budget, so the Appropriations Committee controls the smaller but still enormous discretionary share.

The Twelve Subcommittees and the Cardinals

Most of the work happens inside the 12 subcommittees, each of which drafts a single annual bill covering a distinct set of agencies:⁴

Agriculture, Rural Development, Food and Drug Administration: farm programs, food safety, rural infrastructure
Commerce, Justice, Science: FBI, federal courts, NASA, NOAA, the Census Bureau
Defense: Department of Defense operations, weapons systems, military readiness
Energy and Water Development: Department of Energy, Army Corps of Engineers, nuclear programs
Financial Services and General Government: Treasury, IRS, federal buildings, the judiciary
Homeland Security: Customs and Border Protection, FEMA, TSA, the Coast Guard
Interior, Environment: national parks, EPA, tribal programs, wildfire management
Labor, Health and Human Services, Education: NIH, CDC, job training, student aid
Legislative Branch: operations of Congress itself, the Library of Congress, the Capitol Police
Military Construction, Veterans Affairs: base construction, VA healthcare, veterans’ benefits
National Security, Department of State: foreign aid, embassy operations, international organizations
Transportation, Housing and Urban Development: FAA, highways, transit, housing assistance

Each subcommittee has its own chair and ranking member. The chairs are informally called “Cardinals” because of the leverage they hold over their slice of federal spending. The Defense Cardinal, for example, shapes a bill that accounts for roughly half of all discretionary spending. Above them sit the committee’s top two leaders. In the 119th Congress, Chairman Tom Cole of Oklahoma sets the agenda for the majority, and Ranking Member Rosa DeLauro of Connecticut leads the minority side.¹

How a Spending Bill Moves Through the Committee

The federal fiscal year runs from October 1 through September 30, so fiscal year 2026 began on October 1, 2025.⁵ The goal is to have all 12 bills signed into law by that date. In practice, Congress almost never finishes on time.

The cycle starts when the President submits a budget request to Congress, which by law must arrive no later than the first Monday in February.⁶ That document lays out the administration’s spending priorities. It is a starting point, not a binding plan, and Congress routinely ignores large portions of it.

Once the request lands, subcommittees hold hearings. Agency heads, military commanders, and program administrators testify about their funding needs. From that record, each subcommittee moves into markup, drafting and amending the text of its bill. When a subcommittee approves its version, the bill goes to the full Appropriations Committee for a second markup. A majority vote there sends it to the House floor.

The Senate runs a parallel process. When the two chambers pass different versions, they have to reconcile the differences. Sometimes one chamber adopts the other’s bill; more often a conference committee negotiates a compromise, or the chambers exchange amendments until they agree.⁷ The final product goes to the President for signature or veto.

The 302(b) Allocations

Before any subcommittee can write a bill, it needs to know how much money it has. Under the Congressional Budget Act, the full committee receives a single spending cap called the 302(a) allocation, then divides it among the 12 subcommittees. Those subdivisions are the 302(b) suballocations, and they are enforceable: a bill that exceeds its 302(b) number is subject to a point of order on the floor, which can kill it before a vote ever happens.⁸

These allocations are where much of the real fighting occurs. A dollar added to Defense is a dollar taken from somewhere else. Committee reports accompanying each bill spell out how the money is distributed down to the line-item level, often revealing priorities the bill text alone does not show.

When the Bills Don’t Pass on Time

Congress has completed all 12 bills on schedule only a handful of times in the past five decades. The usual fallback is a continuing resolution, a temporary measure that keeps the government funded at roughly the prior year’s levels while negotiations continue.⁹ A CR can last a few weeks or stretch across the entire fiscal year.

Running the government on a continuing resolution freezes spending at old levels. New programs cannot start. Agencies cannot shift resources to meet changing needs. Military construction stalls. Research grants get delayed. A full-year CR is functionally a decision to do nothing new for twelve months.

Government Shutdowns

If Congress fails to pass either regular appropriations or a continuing resolution, the result is a funding lapse, commonly called a shutdown. The Antideficiency Act prohibits agencies from spending money they don’t have, so most federal operations grind to a halt.¹⁰

Each agency sorts its workforce into two groups. Employees whose work is tied to the safety of human life or the protection of property are “excepted” and must keep reporting to work without pay.¹¹ That group includes active-duty military, air traffic controllers, border agents, and federal law enforcement. Everyone else is furloughed.

The public effects hit fast. National parks close or go unstaffed. Passport processing slows. Federal food safety inspections are suspended. Small business loan applications stop moving. If a shutdown drags on, nutrition programs like WIC run out of funding and housing assistance payments are jeopardized. Under the Government Employee Fair Treatment Act of 2019, furloughed and excepted employees are entitled to retroactive pay once funding resumes.¹²

Policy Riders on Spending Bills

Appropriations bills are supposed to be about money, not policy. House Rule XXI, Clause 2 bars provisions that change existing law in a general appropriations bill, with narrow exceptions for provisions that cut spending or rescind prior appropriations.¹³

Members routinely try anyway. A rider might block funding for a specific regulation, prohibit an agency from enforcing a particular rule, or restrict how grant money can be used. If drafted as a spending limitation rather than an affirmative mandate, the provision doesn’t technically change existing law. The line between a legitimate limitation and disguised legislation is one of the most frequently litigated procedural questions on the floor. A well-crafted rider can effectively kill a policy without ever repealing the law behind it. Senate rules on this point are generally looser, so conference negotiations often become the venue where riders are either stripped out or cemented in.

Community Project Funding

After a long ban, Congress brought back member-directed spending in 2021 under the label “Community Project Funding.” These are the modern version of earmarks. For fiscal year 2026, total Community Project Funding across all House appropriations bills is capped at half of one percent of discretionary spending, and each member can submit up to 15 project requests across all bills.¹⁴

Every request must be tied to an existing federal authorization law, and for-profit entities are ineligible. Members must publicly certify that neither they nor their immediate family have any financial interest in the projects they request, and every request must be posted on the member’s official website in searchable format. The committee publishes a full list of funded projects on the day of a bill’s initial markup, identifying which member requested each one. The Government Accountability Office audits a sample and reports its findings to Congress. Memorials, museums, and anything named after an individual or entity are not eligible.

How to Follow the Committee’s Work

The committee’s official site at appropriations.house.gov publishes hearing schedules, witness testimony, bill text, and committee reports, and is the best starting point if you are tracking a specific bill or subcommittee.⁴ For legislative tracking, Congress.gov is the primary repository. House appropriations bills carry the prefix “H.R.” followed by a number assigned at introduction, and a search there pulls up full text, amendment history, vote records, and committee reports. Those reports are worth reading closely. They contain line-item funding tables and explanatory language that reveal priorities the bill text alone does not show, including the 302(b) allocation breakdowns that set the ceiling for each subcommittee.⁸
