Secure U.S. Leadership in Space Act of 2025

This bill changes federal tax rules so spaceports are treated like airports under “exempt facility bond” rules, a special kind of financing in federal tax law. It spells out what counts as a spaceport: facilities at or near a launch or reentry site used for things like making or fixing spacecraft or parts, flight control, launch and reentry services, and moving crew, spaceflight participants, or space cargo such as satellites and scientific experiments. A spaceport does not have to be open to the general public to qualify, and related manufacturing facilities or industrial parks can be included.

The bill also sets financing rules to make projects easier to qualify. If a spaceport sits on federal land leased to a government, it can still count as government-owned for these bonds if the leases meet the requirements. These bonds won’t be considered “federally guaranteed” just because the U.S. government pays rent or fees to use the spaceport. Bonds for spaceports also won’t count against a state’s limit on these bonds if at least 95% of the money goes to provide a spaceport, and the changes apply to bonds issued after the bill becomes law.

Key points

• Who is affected: Governments financing spaceport projects; spaceport operators and facilities tied to launches and reentries.
• What changes: Spaceports are treated like airports under exempt facility bond rules; public access isn’t required; related manufacturing/industrial park uses can qualify; special rules for federal-land leases; not treated as federally guaranteed just because the U.S. uses the site; excluded from state bond limits if 95% of proceeds fund a spaceport .
• When: Applies to bonds issued after enactment.
