Summary

The U.S. Department of Homeland Security (DHS) is the third largest agency in the federal government in terms of civilian personnel. In FY2024, the annual appropriations bill that funded it was the sixth largest of the 12 annual funding measures developed by the appropriations committees. It is the only appropriations bill that funds a single agency exclusively and in its entirety.

The second administration of President Donald Trump came into office with the government operating under a continuing resolution, and amidst discussion between the congressional majority and the President about using the reconciliation process to enact a significant portion of the President's policy agenda. Development of this FY2025 reconciliation bill overlapped with the resolution of the FY2025 appropriations process with enactment of a full-year CR (P.L. 119-4) in March, and the start of the FY2026 appropriations process.

Starting in April, elements of the reconciliation package became public as sections of the bill were marked up in House committees. Congress ultimately developed an FY2025 reconciliation package (P.L. 119-21) that would be enacted on July 4, 2025. The bill included $178 billion in funding for DHS—the largest single package of DHS supplemental appropriations ever put before Congress. The measure included unprecedented amounts of funding for border security and immigration enforcement (with limited specificity as to how the funding was to be divided across specific accounts or activities), as well as for U.S. Coast Guard acquisitions. Supplemental funding was also provided for the U.S. Secret Service and the Federal Law Enforcement Training Center.

While this process was unfolding, the FY2026 appropriations process began on a parallel track. The President released an initial budget outline on May 2, 2025, and the budget Appendix, which includes appropriation-level detail and proposed legislative language on May 30, a week before the House Appropriations Committee Homeland Security Subcommittee made their proposed bill public.

The Administration's budget request indicated that the annual appropriations and reconciliation funding were intended to complement one another. When evaluating this information, the structure of the funding provided in P.L. 119-21 and limited publicly available information about spending plans for those resources may present some challenges in analyzing the Administration's annual budget request.

Introduction

The second administration of President Donald Trump came into office with the government operating under a continuing resolution, and amidst discussion between the congressional majority and the President about using the reconciliation process to enact a significant portion of the President's policy agenda. Development of this FY2025 reconciliation bill overlapped with the resolution of the FY2025 appropriations process with enactment of a full-year continuing resolution ("CR", P.L. 119-4) in March, and the start of the FY2026 appropriations process, during which the annual budget request was transmitted later than any year in the history of the department of Homeland Security (DHS). The enacted reconciliation measure (P.L. 119-21) would ultimately include more than $178 billion for five DHS components and the Secretary of DHS, with limited detail on how much of these funds would be applied to various activities.

This report analyzes DHS-related elements of the FY2025 reconciliation package (H.R. 1; P.L. 119-21) based on publicly available information, and the Trump Administration's appropriations request for FY2026. The intent is to prepare the reader for understanding the context for subsequent action on FY2026 appropriations.

Timeline of Legislative Activity

Two separate processes are defining the resources available to DHS in FY2025 and FY2026: the budget reconciliation process for FY2025 and the annual appropriations process. The overlapping of these processes may present some challenges or uncertainties in analysis for some observers.

Table 1 presents a timeline of budget and DHS appropriations actions from the inauguration of the second Trump Administration through Congress's August 2025 District Work Period. The first and second columns to the right of the date indicate the status or change in status of the budget and reconciliation process and the appropriations process, respectively. The fourth column includes the budget process timeline outlined in the Congressional Budget Act of 1974 (Titles I-IX of P.L. 93-344; 2 U.S.C. §§601-688), as it would have applied to FY2026.

The Context for FY2026 DHS Budget Request

FY2025 Appropriations

As the 119^th Congress began, the federal government was operating under an extension of an interim continuing resolution (P.L. 118-158 and P.L. 118-83, respectively). The interim continuing resolution (CR) included a $231 million supplemental appropriation for the U.S. Secret Service in the wake of the July 2024 shooting incident during then-candidate Donald Trump's campaign rally in Butler, PA.¹ The extension included $29 billion for the Disaster Relief Fund (DRF), $313 million for the U.S. Coast Guard, and $14 million for the Federal Law Enforcement Training Center as part of a disaster assistance package.² Congress did not vote on other supplemental appropriations requests by the Biden Administration related to border security and immigration matters.³

On March 15, 2025, President Trump signed into law P.L. 119-4, the FY2025 Full-Year Continuing Appropriations and Extensions Act, which set funding levels for the federal government through FY2025, largely based on FY2024 funding levels, with some exceptions.⁴ The full-year CR included $93.69 billion in gross discretionary budget authority for DHS. Of this, $22.51 billion was for the costs of major disasters (which received special exemption from discretionary budget limitations), $6.24 billion was paid for by offsetting collections, and $163 million was offset by rescissions, which reduced the net discretionary budget authority in the measure to $64.79 billion.

FY2025 Reconciliation

As the 119^th Congress began, discussions between the incoming Administration and the congressional majority were already underway to develop a budget reconciliation package that would enact a large portion of the incoming Trump Administration's policy agenda. The bill was envisioned to include border security funding, additional defense spending, extension of expiring tax cuts, and an increase in the debt limit, among other elements.⁵ The President signed the FY2025 reconciliation package (P.L. 119-21) into law on July 4, 2025. The law included the largest single package of DHS supplemental appropriations acted on by Congress to date.

When the bill initially passed the House on May 22, 2025, it included $178.19 billion in mandatory budget authority for DHS: $165.59 billion for six components, and $12.60 billion in directed to DHS activities through the Secretary. When the bill was signed into law on July 4, 2025, it included $191.02 billion for DHS: $168.96 billion for those same six components, and $22.06 billion directed through the Secretary. In total, this was almost double the funding provided in the FY2024 annual appropriations process, and included more than three times the non-disaster grant funding appropriated that year.

Component-specific funding was provided for:

U.S. Customs and Border Protection (CBP)—$64.73 billion, including:

• $46.55 billion for border infrastructure and wall system;⁶
• $6.17 billion for a range of border security, technology, and screening operational and procurement costs;⁷
• $4.1 billion for hiring additional agents, officers, and support personnel;⁸
• $2.05 billion for recruitment bonuses, performance awards, and retention bonuses;⁹
• $0.86 billion for vehicles;¹⁰ and
• $5 billion for CBP facilities.¹¹

U.S. Immigration and Customs Enforcement (ICE)—$74.85 billion, including:

• $45 billion for detention capacity;¹² and
• $29.85 billion for a range of operational and procurement costs.¹³

U.S. Coast Guard (USCG)—$24.59 billion for procurement and certain maintenance costs.¹⁴

U.S. Secret Service (USSS)—$1.17 billion for "additional United States Secret Service resources," including a newly authorized set of performance, retention and signing bonuses.¹⁵

Federal Emergency Management Agency (FEMA)—$2.88 billion, including:

• $0.5 billion for State and local capabilities to detect, identify, track, or monitor threats from unmanned aircraft systems;
• $0.63 billion security and other costs related to the 2026 FIFA World Cup;
• $1.0 billion for security, planning, and other costs related to the 2028 Olympics;
• $0.45 billion for the Operation Stonegarden Grant Program;¹⁶ and
• $0.30 billion to reimburse law enforcement costs for support requested by the U.S. Secret Service in protecting presidential residences.¹⁷

Federal Law Enforcement Training Centers (FLETC)—$0.75 billion, including

• $0.29 billion for supporting training activities; and
• $0.47 billion for facilities.¹⁸

The bill also provided $22.06 billion to the Office of the Secretary for a variety of purposes, including:

• $10 billion "for reimbursement of costs incurred in undertaking activities in support of the [DHS] mission to safeguard the borders of the United States";¹⁹
• $10 billion for a "State Border Security Reinforcement Fund," which provides grants to states for border barrier construction and related activities, certain countersmuggling activities, and relocation of undocumented aliens;²⁰
• $2.06 billion for
• Hiring and training of U.S. Customs and Border Protection (CBP) agents and support staff (in addition to what was included for these purposes elsewhere in the measure) "to carry out immigration enforcement activities";
• Transportation and related costs associated with the departure or removal of aliens;
• Assignment of DHS employees and State officers to carry out immigration enforcement activities;
• Hiring additional staff for screening and vetting of aliens;
• Certain activities related to alien children, including criminal and gang checks and removal;
• Transporting and return of aliens from contiguous territory;
• State and local participation in certain homeland security efforts;
• Certain types of removal of criminal aliens; and
• Information technology investments to support immigration-related activities.²¹

No specific plan for use of the enacted budget authority in either FY2025 or FY2026 had been made public by September 1, 2025.

Table 2 includes some comparisons that may be useful in putting these funding levels in context with historical funding levels for the department. The table presents the most recent year of identifiable comparable funding, as well as a five-year historical total, as the funding from P.L. 119-21 is generally available for obligation for five fiscal years.

The FY2026 DHS Budget Request

Under current law, the President is required to submit a budget request to Congress no later than the first Monday in February. It is not unusual for an incoming Administration's initial budget request to be delayed. In such cases, a discretionary budget request (known colloquially as a "skinny budget") is often presented to Congress to enable congressional debate on a budget resolution. This skinny budget is traditionally followed by a more complete request, which fulfils the remaining statutory requirements.²²

As noted in Table 1, President Trump released a skinny budget for FY2026 on May 2, 2025.²³ This document provided an overall outline of intentions for agency budgets, including DHS. However, the request did not include complete details below the Department level, or justifications. Although it described an FY2026 budget providing DHS $107.4 billion in discretionary funding—which would represent an increase of $42.3 billion from the FY2025 enacted level—$43.8 billion of that total was to come from the additional multiyear budget authority in the reconciliation package that was still pending at the time.²⁴

Later that month, on May 30, the Trump Administration released the FY2026 Budget Appendix, outlining account-level detail of its budget request.²⁵ Over the ensuing weekend, DHS released its budget justifications on its website. This release of departmental budget justifications occurred later than in any prior year for DHS.

The FY2026 budget appendix did not include a specific breakdown of intended uses of the resources provided to DHS through the reconciliation package, which was still working its way through Congress. It did include an allowance for that funding, projecting that $43.75 billion would be spent from the reconciliation package funding in FY2026, broken down by general issue areas (see Table 3).²⁸

DHS Budget Structure

The budget for DHS includes a variety of discretionary and mandatory budget authority. Aside from standard discretionary spending, which provides the bulk of departmental resources,²⁹ some of the discretionary spending in the bill is offset by collections of fees, reducing the net effect on the general fund of the Treasury.

Additionally, a large portion of the funding FEMA receives for the DRF has received special budgetary exemptions from subcommittee allocations and statutory spending limits.³⁰

The DHS mandatory budget authority in the annual request is, for the most part, not referenced in annual appropriations legislation. Some mandatory spending items require funding in appropriations acts because there is no dedicated source of funding to meet the government's obligations established in authorizing laws—such as the U.S. Coast Guard (USCG) retirement accounts.³¹ Figure 1 shows a breakdown of these different categories from the FY2025 budget request.

Figure 1. FY2026 Budget Request Structure

Notes: "Discretionary Appropriations" reflects the offsetting effect of the disaster relief designation and the offset and fee-funded discretionary budget authority shown in the two bars below it. The Administration's accounting for appropriated mandatory budget authority includes the Aviation Security Capital Fund and several U.S. Coast Guard items: Retired Pay, Boat Safety, Maritime Oil Spill Program, and General Gift Fund.

Appropriations-Level Analysis

Types of DHS Appropriations

In FY2017, at congressional direction, DHS implemented a Common Appropriations Structure (CAS), reorganizing most DHS discretionary appropriations into four categories:

• Operations and Support (O&S), which generally covers operating salaries and expenses;
• Procurement, Construction, and Improvements (PC&I), which funds planning, development, engineering, purchase, and deployment of assets to support component missions;
• Research and Development (R&D), which provides resources needed to identify, explore, and demonstrate new technologies and capabilities to support component missions; and
• Federal Assistance (FA), which supports grant funding managed by DHS components.

Some DHS appropriations do not fit the CAS categories. For instance, FEMA's Disaster Relief Fund (DRF) is a unique discretionary appropriation that has been preserved separately, in part, due to the history of the high level of public and congressional interest in that particular account.³²

Of the $97.97 billion in gross discretionary budget authority requested for DHS in FY2026, $94.1 billion (96.0%) falls into the four CAS categories and the DRF.³³

The CAS structure typically allows for a relatively straightforward comparison of the level of departmental investment in these broad categories across components. However, as the Administration has not provided a crosswalk of the reconciliation funding to specific appropriations, the ratios presented in this product are less representative of proposed investment in FY2026 than they were in prior years.³⁴

Table 4 shows the values of the four CAS categories and the DRF in detail, and expresses that value as a share of total annual DHS discretionary appropriations.³⁵ The following columns show the comparable ratio for the FY2025 requested and enacted annual appropriations.

A visual representation of the underlying data from the first two columns follows in Figure 2. On the left are the four appropriations categories of the CAS, plus the DRF and a catch-all "other" category for discretionary spending not included in these activity types.³⁶ A black bar represents (to scale) the FY2025 funding levels requested for DHS for each category. Colored lines flow to the DHS components listed on the right showing the amount of funding requested in each category to each component.

Table 5 presents the requested gross discretionary budget authority for FY2026 for each DHS component, as well as the funding level requested for FY2025 and enacted through the full-year continuing resolution (CR) in P.L. 119-4.

• Four analytical columns on the right side of the table provide comparisons of the FY2026 requested funding levels with the FY2025 requested and enacted annual funding levels, indicating dollar and percentage change.
• Components are listed in the order in which they appear in the DHS appropriations measures.
• The indented and italicized line beneath the FEMA entry shows the portion of the value above that is covered by the special budgetary adjustment for disaster relief.

DHS Staffing

The O&S appropriation for each component pays for most DHS personnel.³⁷ Table 6 and Table 7 analyze changes to DHS staffing, as illuminated by the budget request's information on positions and full-time equivalents (FTEs)³⁸ for each component. Appropriations legislation does not explicitly set these levels, so the information for the following analysis is drawn from the DHS budget justifications.

The Administration has not made public any information on the number of positions or FTE that would be funded by the reconciliation package, neither through the budget justifications nor in other publicly available material.³⁹

In Table 6, the first two data columns indicate the number of positions requested for each component in the FY2026 budget request—expressed numerically, and then as a percentage of total positions. The next three columns show the number of positions funded in the enacted FY2024 annual appropriations measure for DHS and the difference between the FY2026 request and the FY2024 number—expressed numerically, then as a percentage change. Table 7 shows the same analysis for FTEs. Note that neither funded positions nor FTE are direct indicators of current actual staffing levels.

In examining the O&S appropriations for each component later in this report, note that the Administration requested a pay freeze for all civilian employees for 2026 in their budget request, while it requested a 3.0% increase for military personnel.⁴⁰ Therefore only the USCG request reflects pay increase costs, for roughly 44,437 personnel.

Comparing the FY2026 Discretionary Appropriations Request to Prior-Year Levels

The following visual summaries of the budget requests for DHS components are drawn from a survey of the DHS FY2026 budget justifications for each component.

Each visual summary presents a figure showing two comparisons:

• The first outlines the request for FY2026, the annual enacted level for FY2025, and the request for FY2025, showing the share of each component as a black bar within the whole of DHS. The data label on the left of the bar shows the requisite level for the component (the black portion of the bar), and the label on the right shows the level for the remainder of DHS (the gray portion of the bar).
• The second outlines the breakdown by CAS appropriations category (as described above) for the request for FY2026, the annual enacted level for FY2025, and the request for FY2025.

The figures are presented in the following order:

Title II: Law Enforcement Operational Components

• U.S. Customs and Border Protection
• U.S. Immigration and Customs Enforcement
• Transportation Security Administration
• U.S. Coast Guard

FY2026 House Appropriations Committee Action

On June 9, the House Appropriations Committee Homeland Security Subcommittee marked up its version of the FY2026 DHS appropriations act. The full committee marked up the bill on June 24, and reported it out as H.R. 4213, with H.Rept. 119-173 accompanying it. The bill included $66.36 billion in discretionary appropriations, according to the House Appropriations Committee.⁴¹ The bill also included $26.47 billion for the Disaster Relief Fund as requested by the Administration, designated as being for the costs of major disasters, and therefore essentially exempt from discretionary spending limits.⁴²

Potential Considerations

The funding provided in the FY2025 reconciliation package represents the highest multi-year budget authority on record for CBP, ICE, and the USCG, as well as to the Secretary. The structure of that funding and the limited public information on the Trump Administration's spending plans complicate identifying and prioritizing DHS's remaining funding requirements for FY2026.

Congress has traditionally made determinations about funding levels for all aspects of the Department of Homeland Security, and the diverse missions of its components, through the appropriations process, rather than through reconciliation. While the funding provided through P.L. 119-21 greatly exceeds the entire annual DHS budget, it does not resource the entire department. Various functions of seven of its 15 components received reconciliation resources. It remains unclear how these resources will affect the final resolution of the FY2026 DHS appropriations act.

The reconciliation funding is, for the most part, available through FY2029. Initial distributions of some of the budget authority have already occurred, with ICE and the USCG receiving clearance from OMB to begin obligating almost all the budget authority provided them in P.L. 119-21.⁴³ Footnotes on those apportionments indicate that OMB has directed DHS to provide spending plans for the resources provided in P.L. 119-21. Congress may wish to review those spending plans as well.
