Functional Categories of the Federal Budget
Bill Heniff Jr.
Consultant in American National Government
Government and Finance Division
The President's budget and the congressional budget resolution classify federal
budgetary activities into functional and subfunctional categories that represent the major
purposes of the federal government. Each budgetary activity of the federal government,
including budget authority, outlays, tax expenditures, and credit authority, is classified into
a subfunction based on the primary purpose it serves without regard to the agency or other
unit responsible for it. The functional categories provide a broad statement of budget
priorities and facilitate the analysis of trends in related programs regardless of the type of
financial transaction or agency organization.
The annual budget resolution sets forth spending and credit amounts for each
functional category. The amounts are used for informational purposes in the congressional
budget process and are not enforced by points of order. Instead, amounts in each
functional category are distributed to the various congressional committees with
jurisdiction over the spending and credit activities. The committee allocations made under
Section 302 of the Congressional Budget Act (P.L. 93-344) are enforceable through points
of order on the floor of each house. In suballocating their allocations, committees
effectively may alter the functional distributions made in the budget resolution.
Historically, the use of functional classifications by the federal government can be
traced to the first appropriations act. The current function and subfunction classifications
have evolved over time. Under Section 1104(c) of Title 31 U.S.C., the President may
change the form of his budget presentation. Any change in the functional categories,
however, must be made in consultation with the House and Senate Appropriations
Committees and Budget Committees. The General Accounting Office reviews budgetary
classification schemes, from time to time, and makes recommendations for change.1
A list of the 20 functional categories currently included in the federal budget, as well
as the subfunctions, is presented in Table 1. Generally, the first 17 functional categories
reflect major policy areas, while the remaining three represent non-programmatic elements
of the budget that must be included to complete the presentation. Every budgetary
account is assigned an identification code, and the last three digits of these codes designate
the subfunction into which it is classified.
