Comparing DHS Component Funding, FY2024: In Brief

Introduction
The Department of Homeland Security Appropriations Act includes all annual appropriations for
the Department of Homeland Security (DHS), providing resources to every departmental
component. Its accompanying conference report or explanatory statement provides guidance for
the department, including how DHS should distribute those appropriations among various
programs, projects, and activities, and what additional resources Congress anticipates being
available in terms of offsetting receipts and fee revenues that fund specific programs. Together,
these documents form a snapshot of a significant portion of the DHS budget.
This report reviews that snapshot at the DHS component level, comparing
• the budget authority outlined in the FY2023 annual appropriations measure and
its explanatory statement;1
• annual appropriations requested by the Biden Administration for FY2024;2
funding levels recommended by the House Appropriations Committee in committee-reported
H.R. 4367 and H.Rept. 118-123; and
funding levels recommended by the Senate Appropriations Committee in committee-reported S.
2625 and S.Rept. 118-85.
The report makes note of advance and supplemental appropriations provided through various
measures for FY2023 and FY2024, but identifies such funding distinctly, to allow for clear
comparison on the annual appropriations packages. The report makes special note of “net
discretionary appropriations” for DHS—a perspective on the net impact the legislation that funds
DHS has on congressionally tracked budget totals.3

Appropriations Committee responses, see

Security Appropriations Act, 2023.
2 As amended by the Administration on May 9, 2023. See Letter from Joseph R. Biden, Jr., President of the United
States, to The Honorable Kevin McCarthy, Speaker of the House of Representatives, May 9, 2023,

3 When dealing with bill totals, the report refers to “adjusted annual net discretionary appropriations,” which take into
account the offsetting impact of rescissions or cancellations of budget authority provided in prior years. Neither of the
discretionary appropriations totals include emergency or disaster relief-designated funding.

Notes:
a. With the exception of the Total Budget figures in this table, analyses in the report refer to the
Congressional Budget Office’s (CBO’s) estimates of the President’s budget request as outlined in the detail
table at the end of H.Rept. 118-123.
b. This information is drawn from DHS budget documentation. All other amounts in the table are drawn from
congressional documents, which do not reflect a total budget projection.
c. The Administration’s request included up to $4.7 bil ion in contingent emergency-designated supplemental
appropriations for DHS activities at the U.S.-Mexico border.
d. S. 2625 included $4.3 bil ion in emergency-designated appropriations distributed across nine DHS
components.
DHS Budgetary Resources: Beyond the Score
Discussion regarding annual appropriations often centers on one of two numbers:
• the total level of appropriations or “gross budget authority” provided in the bill;
or
• how the bill “scores” against budget limitations—the net discretionary budget
authority, shown in bold in Table 1.
The gross budget authority amount includes all the budget authority in the bill: discretionary
appropriations, including those designated as disaster relief or emergency requirements,
Congressional Research Service

regardless of offsets from collections or rescissions;4 changes in mandatory programs directed by
the bill; and appropriated mandatory spending. This is a representation of the total budget
authority that the bill would provide the department in the fiscal year if enacted.
The “score” is a total of the net discretionary budget authority provided in the bill. The
Congressional Budget Office generally determines that net value, taking into account:
• the offsetting effects on that gross total of certain collections or rescissions,
• appropriations to fund mandatory programs (in the case of DHS, U.S. Coast
Guard Retired Pay is an appropriation made to fulfil an existing legal obligation,
so it is not “scored” as discretionary spending), and
• disaster relief or emergency designations of certain amounts.
The remaining level represents the “adjusted net discretionary budget authority” provided in the
bill. It does not include programs with appropriations in permanent law. Many of those are listed
as “fee-funded” programs, as their resources are often from fees collected in special funds for a
specifically authorized purpose.
A significant portion of the total resources available to DHS is “controlled” through DHS
appropriations bills and reports.5 Special tables at the end of appropriations conference reports
and explanatory statements include a higher level of detail on the funding provided to the
department, usually at various program, project, and activity (PPA) levels. These tables—known
as detail tables—serve as a level of control for interpreting statutory authorities in the bill that
regulate the ability to transfer funding between appropriations or to reprogram money within an
appropriation.
As the detail tables represent the most complete picture of the DHS appropriations measure and
its effect on the DHS budget, Table 2 uses their data to provide a breakdown of the resources
available to DHS, distributed by component, and further broken down by funding type. This
provides a more complete description of each component’s overall resource level than a review of
the net discretionary appropriations alone.
Each component’s funding level, as a section of Table 2, has five columns, representing the
different phases of the appropriations process: prior-year (i.e., FY2023) enacted, current year (i.e.,
FY2024) requested annual appropriations, and the ensuing responses of the House and Senate
appropriations committees. The final column shows advance appropriations made in FY2022 that
will be available in FY2024.
Two caveats:
1. Some DHS mandatory spending is not included in the detail tables. This includes
spending on flood insurance claims, as well as trust funds for the Coast Guard
and the Secret Service.6

4 A rescission is a cancellation of previously appropriated budget authority.
5 For FY2022, the $90.01 billion in gross resources reflected in the detail table accompanying the annual appropriations
represented 94.1% of the resources made available to DHS for FY2022, not including supplemental appropriations.
6 Information about mandatory spending that is not reflected in the detail tables can be found in the Administration’s
budget request. The FY2024 DHS budget request can be found on the Office of Management and Budget website, or
linked directly at https://www.whitehouse.gov/wp-content/uploads/2023/03/dhs_fy2024.pdf.

2. The detail tables do not reflect reimbursements between components for services
provided, such as payments from partner agencies to the Federal Law
Enforcement Training Center for the cost of training programs.7
Note: The Administration’s proposed $4.7 billion in emergency-designated contingent
appropriations is shown in Table 2 under the Office of the Secretary and Executive Management
(OSEM). Although the Office of the Secretary would have originally received those funds if
certain thresholds of border activity were reached in a timely fashion, they were to be distributed
to U.S. Customs and Border Protection, U.S. Immigration and Customs Enforcement, and the
Federal Emergency Management Agency to support their activities. Given the uncertainty of
whether specific distributions of those funds would be made, and at what level, their potential
practical impact cannot be reflected in either Table 2 or the ensuing figure. Neither the HAC-
reported nor Senate-reported DHS appropriations measure included the contingent appropriations.

7 Information on these projected resource flows can be found in the DHS annual budget justifications submitted to
Congress. The FY2024 DHS budget justification can be found at https://www.dhs.gov/publication/congressional-
budget-justification-fiscal-year-fy-2024.

Figure 1 uses the data in Table 1 to provide a visual representation of the resources available to
seven DHS operational components—the seven largest components of DHS in terms of net
discretionary budget authority:
• U.S. Customs and Border Protection (CBP),
• U.S. Coast Guard (USCG),
• Immigration and Customs Enforcement (ICE),
• Transportation Security Administration (TSA),
• Federal Emergency Management Agency (FEMA),
• U.S. Secret Service (USSS), and
• Cybersecurity and Infrastructure Security Agency (CISA).
In Figure 1, these seven components are listed along the bottom axis, showing the same five
stages for each as in Table 1.
The base (medium blue) segment of each bar represents net discretionary budget authority. Atop
those bars are additional bars that represent other funding types:
• offsetting collections (orange),
• programs paid for directly by fees (gray),
• mandatory appropriations (yellow),
• funding covered by disaster relief (dark blue),8 and
• supplemental appropriations, including advance appropriations (green).9
Atop the column describing the Senate Appropriations Committee (SAC)-reported bill, black
segments indicate emergency-designated funding for the respective components.
Among the changes Figure 1 illuminates are:
• The relative magnitude of disaster spending (which encompasses the mandatory,
disaster relief-designated, and supplemental funding for FEMA) compared with
other DHS funding priorities;
• The Administration’s proposal to provide additional offsetting fee revenue to
support TSA, and how appropriations measures needed to include additional
discretionary funding to maintain the proposed budget in the absence of
authorization to provide those additional revenues; and
• FY2024 advance supplemental appropriations provided in Division J, Title V of
P.L. 117-58 (the Infrastructure Investment and Jobs Act).

8 For more details about adjustments to discretionary spending limits under the BCA, see CRS Report R45778,
Exceptions to the Budget Control Act’s Discretionary Spending Limits, by Megan S. Lynch.
9 Supplemental appropriations in this case also include advance appropriations provided in P.L. 117-58, the
Infrastructure Investment and Jobs Act, Division J.

DHS Appropriations: Comparing Scores
It is often useful to present comparative analysis to put proposed annual funding levels for given
DHS components in context.
Table 3 and Table 4 show a comparison of the House Appropriations Committee (HAC)-reported
and SAC-reported bills to two common baselines: the FY2024 request, and the FY2023 enacted
net discretionary annual appropriation—appropriations provided from the Treasury that are not
offset by other incoming resources or given special exemption.10 In these two tables, the first
column of figures shows the FY2024 enacted annual net discretionary amount for each
component. Changes from that level are reflected in thousands of dollars, and then as a
percentage. The components are ordered from largest to smallest by FY2023 enacted annual net
discretionary budget authority.
FY2023 and FY2024 supplemental and advance appropriations are not reflected in Table 3 or
Table 4. The purpose of these tables is to provide comparative perspectives on annual
appropriations levels, as well as to improve understanding of comparative annual appropriations
levels across the department, rather than to survey total resources provided by Congress, which
can be seen in Figure 1 and Table 2.

Emergency-Designated Funding in Annual
Appropriations Measures
It is atypical for annual appropriations measures to include emergency-designated appropriations.
However, the Biden Administration’s budget proposal—with the inclusion of a $4.7 emergency-
designated contingency appropriation—could be said to have opened the door for atypical
approaches in FY2024. If the Administration’s proposal were enacted, ongoing activities that had
been funded in the FY2023 DHS annual appropriations act could be funded as emergency
requirements in FY2024 if migrant activity at the U.S.-Mexico border reaches certain
thresholds.11
SAC-reported S. 2625 included $4.3 billion in emergency-designated funding distributed across
nine of DHS’s fifteen components. Table 5 lists those components and the appropriations
receiving emergency-designated budget authority in the SAC-reported bill.
