The federal budget determines funding for everything from national defense to education to disaster relief. Understanding how it works — and when key decisions happen — lets you weigh in at the moments your voice matters most.
The federal fiscal year runs from October 1 to September 30. Here's how the annual budget process unfolds:
President's Budget Request (early February)
The President submits a detailed budget proposal to Congress. The Office of Management and Budget (OMB) coordinates with every federal agency to develop this request. It's a wish list and a statement of priorities — Congress is not required to follow it.
Congressional Budget Resolution (March–April)
The House and Senate Budget Committees draft a budget resolution that sets overall spending and revenue targets. This resolution is not signed by the President and has no force of law — it's Congress's internal spending framework. It establishes "302(a) allocations" that cap how much each appropriations subcommittee can spend.
Appropriations Markup (April–September)
Twelve appropriations subcommittees write individual spending bills covering different areas of government — defense, homeland security, education, transportation, and more. This is where line-item funding decisions are made and where detailed advocacy is most effective.
Floor Votes & Conference (summer)
Both chambers debate and vote on appropriations bills. When the House and Senate pass different versions of a bill, a conference committee reconciles the differences into a single version that both chambers must approve.
Presidential Signature or Veto (before October 1)
The President signs each appropriations bill into law or vetoes it. Congress can override a veto with a two-thirds majority in both chambers, though overrides are rare.
Continuing Resolutions
If all 12 bills aren't signed by October 1, Congress typically passes a continuing resolution (CR) to keep the government funded at prior-year levels. CRs are temporary — they buy time but don't set new policy. If no CR or full-year bill passes, affected agencies shut down.
Reconciliation is a special legislative process tied to the budget resolution. It allows Congress to pass certain spending, revenue, and debt-limit changes with a simple majority in the Senate — bypassing the 60-vote filibuster threshold.
Because reconciliation bills can't be filibustered, the majority party can use it to enact major fiscal policy without bipartisan support. This makes it one of the most powerful tools in the legislative process.
Named after Senator Robert Byrd, this rule limits what can be included in reconciliation bills. Provisions must directly affect spending or revenue — "extraneous" policy changes can be struck by the Senate parliamentarian. This is why you sometimes hear that certain provisions were "Byrded" out of a bill.
Major legislation passed through reconciliation includes the Affordable Care Act (2010), the Tax Cuts and Jobs Act (2017), and the Inflation Reduction Act (2022). Both parties use this tool when they hold the majority and want to advance their fiscal agenda.
The debt ceiling is a legal limit on how much the federal government can borrow to pay for obligations Congress has already authorized. It's separate from the budget: Congress authorizes spending in one set of votes and authorizes borrowing in another.
When borrowing hits the ceiling, the Treasury Department uses "extraordinary measures" — accounting maneuvers that free up cash temporarily. If Congress doesn't raise or suspend the ceiling before those measures run out, the government risks defaulting on its obligations, which could disrupt financial markets and government payments.
Congress has raised or suspended the debt ceiling dozens of times since it was established in 1917. Debt ceiling standoffs have become increasingly common and politically charged, making these moments especially important for constituent engagement.
Debt ceiling debates are high-stakes and high-visibility. Officials pay close attention to constituent sentiment during these moments. Contacting your senators and representative during a debt ceiling debate can have real impact.
Sequestration is a mechanism for automatic, across-the-board spending cuts triggered when spending exceeds predetermined caps. It was a central feature of the Budget Control Act of 2011, which imposed caps on discretionary spending. If Congress exceeds the caps, cuts are applied equally to defense and non-defense programs.
Pay-as-you-go (PAYGO) rules require that new spending or tax cuts be offset by spending reductions or revenue increases elsewhere, so they don't increase the deficit. The House uses a related rule called CUTGO, which requires new mandatory spending to be offset only by spending cuts (not tax increases). These rules shape every major fiscal debate.
The Congressional Budget Office (CBO) provides nonpartisan estimates of how much proposed legislation will cost over a 10-year window. These "scores" are enormously influential — a bill's CBO score can determine whether it gains or loses support. When you hear that a bill "costs $1.5 trillion over 10 years," that figure typically comes from the CBO.
Federal budgets are projected from a "baseline" — an estimate of what spending would be if current policies continue unchanged. This means a "cut" in Washington sometimes means spending less than the projected increase, not spending less than last year. Understanding the baseline helps you evaluate claims about budget cuts and increases.
Write the budget resolution that sets overall spending and revenue targets for the year.
Oversee the 12 subcommittees that write individual spending bills. These subcommittees make the specific funding decisions — how much goes to the NIH, how much to the military, how much to housing programs.
Handle tax policy and mandatory spending programs like Social Security and Medicare. If a bill changes taxes or entitlements, it goes through these committees.
A nonpartisan committee that provides revenue estimates and analysis of tax legislation. Their estimates are used alongside CBO scores to evaluate fiscal impact.
