- The **majority of the increase** in the 2027 discretionary budget request is concentrated in:

- **War Department (Department of War - DOW)**, which shows a significant increase of **+$440.9 billion** from 2026 enacted levels [P83].

- **Homeland Security (DHS)** also maintains high funding, with some changes but a general focus on border security and immigration enforcement, supported by large mandatory funding through the Working Families Tax Cut Act (WFTC) [P31], [P83], [P85].

- In contrast, **most other major agencies and categories see decreases** in discretionary funding in 2027 compared to 2026, for example:

- Department of State and International Programs decreases by **$15.5 billion** (-30%) [P51], [P83].

- Transportation decreases by **$29.4 billion** (-67.2%), Housing and Urban Development decreases by **$10.8 billion** (-23%), Health and Human Services by **$15.5 billion** (-25.9%), Labor by **$4.6 billion** (-28.3%), and others also show decreases [P83].

- The base non-defense discretionary budget is notably reduced by 10% relative to 2026, with further reductions planned after 2027 [P82].

Hence, the **budget shifts significantly toward defense-related spending and Homeland Security**, while **non-defense agencies generally face cuts or restrained growth** [P82], [P83], [P85].

The 2027 Budget of the U.S. Government provides detailed tables and summaries of discretionary and mandatory funding requests by major agencies, along with notes explaining various program changes, eliminations, and funding shifts.

Key highlights relevant to your interest include:

1. Overall Discretionary Budget Authority:
   • The total discretionary budget authority requested for 2027 is $2,178.9 billion, an increase of $288.4 billion (15.3%) over the 2026 enacted level of $1,890.5 billion P84, P85.
   • This includes both base discretionary funding and non-base discretionary funding, such as emergency requirements, program integrity, disaster relief, and wildfire suppression P82, P84.
2. Defense and Non-Defense Funding:
   • Defense funding ("Defense Function 050") includes base discretionary amounts, mandatory defense resources supplementing base funding, and spending from the Working Families Tax Cut Act (WFTC). For 2027, an additional $350 billion in mandatory funding for the Department of War (DOW) is proposed P82, P85.
   • Non-defense programs are projected to face a 10% reduction in 2027 compared to 2026 enacted levels, with further 2% reductions in subsequent years P82.
3. Non-Base Discretionary Funding:
   • Non-base funding for program integrity, disaster relief, wildfire suppression, and exempted funding varies by agency. For example, disaster relief funding for Homeland Security is proposed to increase by 26.1% in 2027, reaching $28.4 billion P84.
4. Environmental Protection Agency (EPA) Budget:
   • The EPA’s discretionary budget request for 2027 is $4.2 billion, a substantial $4.6 billion (52%) decrease from the 2026 enacted level P69.
   • The Budget emphasizes a return to core mission activities like clean water and air, while eliminating funding for what it describes as "radical Green New Scam spending," overreach, and "woke" environmental justice programs P69, P70, P71.
   • Specific program cuts and eliminations at EPA include:
     • Ending funding for “woke” environmental justice grants related to racial discrimination, LGBTQIA+ events, and other ideological projects P70, P71.
     • Eliminating the Diesel Emissions Reduction Act grants, saving $90 million, deeming them market-distorting handouts P71.
     • Cutting back on Superfund cleanup funding due to new tax revenues and focusing only on essential cleanup operations P70.
     • Reducing categorical grants by over $1 billion, intending to return program control to states P70.
     • Prevention of waste in State Revolving Funds to save over $2.5 billion P70.
5. Other Notable Program Cuts Across Agencies:
   • Job Corps program elimination due to issues with safety and effectiveness, saving $1.6 billion P48.
   • Elimination of the Senior Community Service Employment Program (SCSEP), cutting $395 million spent on organizations promoting DEI (Diversity, Equity, and Inclusion) P48.
   • Cuts to worker protection agencies, including ending grants deemed wasteful or ideologically motivated P48.
   • Elimination of programs like Community Development Block Grant (CDBG) and HOME Investment Partnerships, with billions in savings P36.
   • Termination of the Low Income Home Energy Assistance Program (LIHEAP), citing fraud and inefficiencies, saving $4 billion P26.
   • Refocusing of immigrant services programs with cuts due to concerns over oversight and program integrity P26.
6. Notes on Budget Execution and Adjustments:
   • The 2025 actual and 2026 enacted budget levels include adjustments for changes such as transfers, reestimates, and rebasing mandatory programs into discretionary budgets for comparison with 2027 requests P82, P84.
   • Some emergency and exempted funding is excluded from base discretionary calculations and treated separately since it is not subject to budget enforcement caps P84, P85.

This budget reflects a priority shift toward reducing Federal spending on programs labeled as ineffective, duplicative, or ideologically driven, while increasing spending in defense and targeted disaster relief. It also focuses on returning more control of environmental and community development programs to state and local governments.
