The FY2027 President's Budget requests $1.07B for Mission Support, within Homeland Security's Operations and Support account. That is up 0.4% on the FY2026 figure of $1.06B, which is a continuing-resolution annualized figure, not an enacted appropriation.
FY2025–FY2027
| Fiscal year | Basis | Amount |
|---|---|---|
| FY2025 | enacted | $1,063.9M |
| FY2026 | CR annualized | $1,063.9M |
| FY2027 | request | $1,068.6M |
The prior-year column is a CR annualized figure — the rate a continuing resolution funds at, not an enacted appropriation. The two are different numbers and are not interchangeable. Bases are separate columns and are never summed into one figure.
Homeland Security discretionary budget authority
From the OMB Public Budget Database — clean, summable, and the figure to cite for an agency total. It is the whole of Homeland Security's discretionary request, not a total of the parsed lines above, and this page never adds the two together.
What this funds
The PPA provides resourcing to support infrastructure required to sustain TSA's Nationwide operations, such as headquarters offices, human resources, Information Technology (IT), and major acquisitions to support those efforts.
Extracted from Transportation Security Administration, p. 5. Verbatim; nothing here is paraphrased.
