Appropriations 101

This paper has been updated here.

What are appropriations?

Appropriations are annual decisions made by Congress about how the federal government spends some of its money. In general, the appropriations process addresses the discretionary portion of the budget – spending ranging from national defense to food safety to education to federal employee salaries – but excludes mandatory spending, such as Medicare and Social Security, which is spent automatically according to formulas.

How does Congress determine the total level of appropriations?

Under current law, after the President submits the Administration’s budget proposal to Congress, the House and Senate Budget Committees are each directed to report a budget resolution that, if passed by their respective houses, would then be reconciled in a budget conference (see Q&A: Everything You Need to Know About a Budget Conference).

The resulting budget resolution, which is a concurrent resolution and therefore not signed by the President, includes what is known as a 302(a) allocation that sets a total amount of money for the Appropriations Committees to spend. For example, the conferenced budget between the House and Senate set the 302(a) limit for Fiscal Year (FY) 2016 at $1.017 trillion.

In the absence of a budget resolution, each chamber may enact a deeming resolution that sets the 302(a) allocation for that chamber. The Bipartisan Budget Act of 2018 gave the Chairmen of the Budget Committees authority to set the 302(a) allocation for the Appropriations Committees for FY 2018 and FY 2019 at the statutory discretionary spending caps set by the law. For the upcoming year (FY 2020), Congress may also set the 302(a) allocation using an alternative method, depending on whether lawmakers enact legislation to address the statutory spending caps. The House adopted a rule on April 9 that deemed the 302(a) level for FY 2020 that exceeds the caps, while the Senate Budget Committee approved a budget resolution in March that assumes the caps remain at their statutory levels while allowing them to be adjusted if an agreement is reached.

Discretionary spending has been subject to statutory spending caps since 2013. The Budget Control Act of 2011 set discretionary caps through 2021, which have been modified by the American Taxpayer Relief Act of 2012, the Bipartisan Budget Act of 2013, the Bipartisan Budget Act of 2015, and the Bipartisan Budget Act of 2018. For 2020 and 2021, the statutory caps set by the Budget Control Act will be reduced by about $90 billion annually through an enforcement mechanism known as “sequestration” (see Understanding the Sequester) implemented after the failure of the 2011 Joint Select Committee on Deficit Reduction to produce legislation to reduce deficits.

How does Congress allocate appropriations?

Once they receive 302(a) allocations, the House and Senate Appropriations Committees set 302(b) allocations to divide total appropriations among the 12 subcommittees dealing with different parts of the budget. The subcommittees then decide how to distribute funds within their 302(b) allocations. 302(b) allocations are voted on by the respective Appropriations Committees, but they are not subject to review or vote by the full House or Senate. The table below lists the FY 2019 regular (non-war, non-disaster) appropriations along with the House’s FY 2020 302(b) allocations and the Senate Budget Committee’s proposed 302(a) allocation in its budget resolution. (It will be updated following the release of Senate 302(b) allocations for FY 2020.)


This table excludes funding not subject to the spending caps, such as Overseas Contingency Operations (OCO) or disaster funding. The Bipartisan Budget Act of 2018 allowed for $77 billion in OCO funding in FY 2019. The President’s budget calls for $165 billion in OCO funding for FY 2020, while the House deeming resolution and Senate Budget Committee call for $77 billion and $67 billion in OCO funding, respectively.

Each subcommittee must propose a bill that ultimately must pass both chambers of Congress and be signed by the President in order to take effect. Although the budget process calls for 12 individual bills, many of them are often combined into what is known as an omnibus appropriations bill and sometimes a few are combined into what has been termed a minibus appropriations bill.

How are appropriations levels enforced?

If any appropriations bill or amendment in either chamber exceeds the 302(b) allocation for that bill, causes total spending to exceed the 302(a) allocation, or causes total spending to exceed the statutory spending caps, any Member of Congress can raise a budget “point of order” against consideration of the bill. The House can waive the point of order by a simple majority as part of the bill’s rule for floor consideration, and the Senate can override it through a 60-vote majority. If, despite these points of order, Congress enacts legislation increasing spending beyond the defense or non-defense caps, then the President must issue a sequestration order to reduce discretionary spending across the board in the category in which the caps were exceeded, effective 15 days after Congress adjourns for the year. Importantly, certain types of discretionary spending – including OCO and designated emergencies – do not count against the statutory caps.

What happens if funds are needed outside of the appropriations process?

After initial appropriations bills have been signed into law, Congress can pass a supplemental appropriations bill in situations that require additional funding immediately, rather than waiting until the following year’s appropriations process. Supplementals are often used for emergencies such as natural disasters or military actions. Occasionally, Congress has used supplemental appropriations to stimulate the economy or to provide more money for routine government functions after determining that the amount originally appropriated was insufficient. Supplemental appropriations bills are subject to the same internal and statutory spending limits as regular appropriations and require the same offsets to ensure they do not exceed spending limits unless designated as emergency spending.

What role does the President play in the appropriations process?

Although the President has no power to set appropriations, he or she influences both the size and composition of appropriations by sending requests to Congress. Specifically, each year the President’s Office of Management and Budget (OMB) submits a detailed budget proposal to Congress based on requests from agencies. The appendix to the President’s budget submission contains much of the technical information and legislative language used by the Appropriations Committees. In addition, the President must sign or veto each of the appropriations bills, giving him or her additional influence over what the bills look like.

What is the timeline for appropriations?

The 1974 Budget Act calls for the President to submit his or her budget request by the first Monday in February and for Congress to agree to a concurrent budget resolution by April 15. The House may begin consideration of appropriations bills on May 15 even if a budget resolution has not been adopted, and it is supposed to complete action on appropriations bills by June 30. (The process is generally designed for the House to take the lead on appropriations and the Senate to follow.) However, none of these deadlines are enforceable, and they are regularly missed. The practical deadline for passage of appropriations is October 1, when the next fiscal year begins and the previous appropriation bills expire. For a full timeline of the budget process, read more here.

What happens if appropriations bills do not pass by October 1?

If appropriations bills are not enacted before the fiscal year begins on October 1, federal funding will lapse, resulting in a government shutdown. To avoid a shutdown, Congress may pass a continuing resolution (CR), which extends funding and provides additional time for completion of the appropriations process. If Congress has passed some, but not all, of the 12 appropriations bills, a partial government shutdown can occur.

What is a continuing resolution?

A continuing resolution, often referred to as a CR, is a temporary bill that continues funding for all programs based on a fixed formula, usually at or based on the prior year’s funding levels. Congress can pass a CR for all or just some of the appropriations bills. CRs can increase or decrease funding and can include “anomalies,” which adjust spending in certain accounts to avoid technical or administrative problems caused by continuing funding at current levels, or for other reasons.

What happens during a government shutdown?

A shutdown represents a lapse in available funding, and during a shutdown the government stops most non-essential activities related to the discretionary budget. To learn more, see Q&A: Everything You Should Know About Government Shutdowns.

Do agencies have any discretion in how they use funds from appropriators?

Executive branch agencies must spend funds provided by Congress in the manner directed by Congress in the text of the appropriations bills. Appropriations bills often contain accompanying report language with additional directions, which are not legally binding but are generally followed by agencies. In some instances, Congress will provide for very narrow authority or use funding limitation clauses to tell agencies what they cannot spend the money on. That said, Congress often provides broad authority, which gives agencies more control in allocating spending. Agencies also have some authority to reprogram funds between accounts after notifying (and in some cases getting approval from) the Appropriations Committees.

What is the difference between appropriations and authorizations?

Authorization bills create, extend, or make changes to statutes and specific programs and specify the amount of money that appropriators may spend on a specific program (some authorizations are open-ended). Appropriations bills then provide the discretionary funding available to agencies and programs that have already been authorized. For example, an authorization measure may create a food inspection program and set a funding limit for the next five years; however, that program is not funded by Congress until an appropriations measure is signed into law. The authorization bill designs the rules and sets out the details for the program, while the appropriations bill provides the actual resources to execute the program. In the case of mandatory spending, an authorization bill both authorizes and appropriates funding for a specific program without requiring a subsequent appropriations law.

Where are the House and Senate in the current appropriations process?

Congress began appropriations work for FY 2020 in March. Lawmakers have been discussing another budget deal to raise discretionary spending caps for FY 2020, but it is currently unclear whether such a deal would complement a budget resolution or supersede it.

The enactment of the 2018 Bipartisan Budget Act increased defense and non-defense discretionary spending caps for FY 2019 at $1.244 trillion, an increase beyond eliminating the “sequester.” Without a similar deal for FY 2020, spending will revert to sequester levels, which are about $126 billion, or 10 percent, lower than the enacted FY 2019 levels.

The Senate Budget Committee approved its budget resolution on March 28 and set 302(a) levels at $1.118 trillion in accordance with sequester-level caps as put into motion by the Budget Control Act. The House Budget Committee approved a caps increase proposal on April 3 that would set discretionary spending levels at $1.295 trillion for FY 2020, and its leaders have indicated that they will likely forgo a formal budget resolution. The House postponed a scheduled vote on the House Budget Committee legislation, but the chamber adopted a rule that deemed 302(a) levels and allowed appropriations to proceed at the proposal’s $1.295 trillion for FY 2020.

The Senate has not acted on its budget resolution, and leaders in both chambers are reportedly negotiating a plan to increase the spending caps. If such a deal is reached, the Senate Budget Committee’s budget resolution would permit adjustment of discretionary spending levels.

The House Appropriations Committee has begun working on individual appropriations bills assuming spending caps are eventually increased. In the Senate, a 302(a) allocation has not been deemed or agreed to yet, so it is unclear when they will begin working on appropriations.
