Budget of the U.S. Government

Congress is responsible for creating the federal government's annual budget.

Congress must create and pass numerous funding bills each fiscal year to keep the federal government open. This infographic explains the process.

  • Each year, Congress works on a federal budget for the next fiscal year. The government’s fiscal year runs from October 1 of one year to September 30 of the next. The budget includes a detailed spending plan.

    The Constitution puts Congress in charge of the budget, granting it the power to collect taxes, borrow money, and approve spending.

    How does the government get money? Where does it go?

    Most government money comes from:

    • Collecting taxes, or revenue, from people and businesses

    • Borrowing it by selling Treasury securities (savings bonds, notes, and Treasury bills)

    The government spends money on:

    • Social Security, Medicare, and other mandatory spending required by law

    • Interest on the debt--the total the government owes on all past borrowing

    • Discretionary spending, the amount Congress sets annually for all other programs and agencies.

    Creating the budget, step by step

    Departments and agencies submit proposals

    About 1 ½ years before a budget goes into effect, agencies start work on their proposals. These go to the White House to help create the President’s budget request.

    The President submits his plan

    Typically by the first Monday in February, the President gives Congress his budget proposal for the next fiscal year.

    The House of Representatives and the Senate create budget resolutions

    Each chamber of Congress analyzes the President’s budget proposal and drafts a budget resolution  setting overall spending levels. A conference committee of House and Senate members resolves differences between the two plans to create a final version that each chamber votes on.

    Appropriations committees distribute funding

    House and Senate appropriations committees divide the discretionary spending portion of the budget resolution among 12 subcommittees. Each subcommittee oversees a different group of agencies, like Interior and Environment or Transportation and Housing. The subcommittees draft appropriations bills setting the funding for each agency.

    Chambers vote on appropriations bills

    The full House and Senate vote on their bills. Both versions of each bill go to a conference committee to merge the two. Both chambers vote on the same version of each bill. If approved, it goes to the President.

    The President signs the bills into law.

    If any appropriations bill is not signed by September 30, the government will not have a budget for the new fiscal year.

    Without a budget, many government services stop

    With no budget, Congress must pass a continuing resolution to fund the government temporarily. Otherwise, the government will shut down, and many functions will stop.

    If Congress can’t agree on 12 separate appropriations bills, it can pass an Omnibus bill that includes multiple funding areas. If the President signs that, the budget becomes law and goes into effect.

How the Federal Government Creates and Manages Its Budget

Every year, Congress begins work on a federal budget for the next fiscal year. The federal government’s fiscal year runs from October 1 of one calendar year through September 30 of the next.

The work actually begins in the executive branch the year before the budget is to go into effect.

  • Federal agencies create budget requests and submit them to the White House Office of Management and Budget (OMB).
  • OMB refers to the agency requests as it develops the president’s budget proposal.

The president submits his budget proposal to Congress early the next year. Then Congress, which the Constitution puts in charge of spending and borrowing, starts its work.

Annual Funding Areas

The annual budget covers three spending areas:

  • Federal agency funding, called discretionary spending—the area Congress sets annually. Discretionary spending typically accounts for around a third of all funding.

  • Interest on the debt, which usually uses less than 10 percent of all funding

  • Funding for Social Security, Medicare, veterans benefits, and other spending required by law. This is called mandatory spending and typically uses over half of all funding.

The Complex Role of Congress in the Budget Process


For agencies and their programs to be funded, Congressional authorization committees must pass, and the president must sign, authorization bills giving agencies the legal authority to fund and operate their programs. Normally, without authorization, an agency or program cannot receive annual appropriated funding.

Authorization is not tied to the same schedule as the budget appropriations process; programs can be authorized at any time of year on an annual, multi-year, or permanent basis.

Budget Resolutions

Congress’s first task in the annual process is to pass a budget resolution creating a framework and setting overall spending limits. As with most things Congress does, its two chambers—the Senate and the House of Representatives—each draft their own budget resolution. The two plans are merged, and each chamber votes on the identical resolution.

Appropriations Bills

The appropriations committee for each chamber divides the amount allotted for federal agency funding between 12 subcommittees. Each subcommittee is in charge of funding for different functions of government, such as defense spending, energy and water, and interior and environment, and for the agencies involved.

The subcommittees conduct hearings with agency leaders about their budget requests and draft appropriations bills setting the funding for each. The full House and Senate vote on their bills, merge both versions of each one, and vote on the identical version of every bill. Each one, if passed, goes to the president for signature

Budget Completion or Government Shutdown

If Congress passes, and the president signs, all 12 bills by September 30—the last day of the current fiscal year—the country has a new budget in time for the start of the next fiscal year. If Congress can’t agree on 12 separate bills, it can pass an Omnibus bill with funding for multiple areas. If the budget is not completed by the new fiscal year, Congress must pass a continuing resolution authorizing temporary funding at the previous year’s levels or face a government shutdown.

In the event of a shutdown, the government stops issuing passports, closes national parks and monuments, halts NASA operations, and puts many other functions on hold.

When the budget process is finally complete or Congress passes a continuing resolution, the government resumes normal operations.

Federal Budget by Fiscal Year

To see the approved federal budget for a year, you must look at the appropriations bills for that year that were signed into law.  

  1. Go to the Appropriations and Budget page on

  2. Click the year you want to see. 

  3. A chart will open. Scroll down to find various versions of budget legislation in it. To identify which budget legislation in the chart actually became law, look in the chart under the far right column titled "Public Law" for a Pub.L. number that was assigned to the legislation when it passed.  

The Deficit, the Debt, and the Debt Ceiling

When the amount of money the government collects in taxes and other revenue in a given year is less than the amount it spends, the difference is called the deficit. If the government takes in more money than it spends, the excess is called a surplus.

The deficit is financed by the sale of Treasury securities (bonds, notes, and bills), which the government pays back with interest. Part of what the government spends money on each year is the interest owed on all years’ deficits combined, or the national debt. Get statistics and learn more about the deficit and national debt from Your Guide to America’s Finances.

The debt ceiling is the maximum amount of debt the government allows itself to hold. Congress can vote to raise the debt ceiling. If it doesn’t and the debt hits the ceiling, the government won’t be able to borrow any more money and it won’t be able to pay its bills.
