FY2026 National Science Foundation
This page contains interactive tables and charts with budget details for the National Science Foundation in fiscal year 2026. It also links to key budget documents, FYI’s analyses of appropriations proposals and outcomes, and major actions in this budget cycle.
Note 1: Although the final spending legislation for fiscal year 2025 provided NSF with the same topline budget as the prior fiscal year, the Trump administration has declined to spend $234 million in “emergency” spending that Congress allocated to the Major Research Equipment and Facilities Construction account. For now the tracker includes this emergency spending as part of the NSF topline for fiscal year 2025, though this amount will be adjusted if the administration succeeds in defunding the account.
Note 2: The Trump administration is proposing to fold the account that funds the STEM Education Directorate into the Research and Related Activities account, which funds NSF’s other directorates. The House bill would accept this proposal while the Senate bill retains the STEM Education account. To ease comparison with the administration and House proposals, the Senate figure for Research and Related Activities has been adjusted to include the STEM Education money.
