TOKYO — Spaceport advocates won a tax break in the budget reconciliation bill that they hope will spur investment, but the provision has also generated a political backlash.
The final version of H.R. 1, the budget reconciliation bill signed into law by President Donald Trump July 4, includes a section that would allow spaceports, like airports, to issue tax-exempt bonds.
The language in the bill is similar to the Secure U.S. Leadership in Space Act of 2024, introduced by a bipartisan group of congressmen and senators in February 2024. The bill was reintroduced in the current Congress as the Secure U.S. Leadership in Space Act of 2025 in May.
The purpose of the bill is to treat spaceports the same as airports regarding their ability to issue municipal revenue bonds, which are exempt from taxes. That would, spaceport advocates say, give spaceports a new avenue for raising money for infrastructure improvements.
In an interview last year, Rob Long, president of the Space Florida, the state’s aerospace finance and development authority, said having that authority would attract investors and potentially reduce the costs of financing spaceport infrastructure projects. “We saw this need and wanted to make sure that we are treating spaceports the same as airports and seaports in terms of the ability to issue tax-exempt bonds,” he said then.
“This legislation will unlock much needed investments in our spaceport infrastructure,” Dave Cavossa, president of the Commercial Space Federation, told SpaceNews after the passage of H.R. 1. “As the U.S. commercial, civil and military space capabilities, like Golden Dome, continue to grow, we must have multiple points of access to space from U.S. soil to keep up with our allies and opponents throughout the world.”
“The provision in the budget reconciliation bill to give spaceport bonds the same tax-exempt status as airport bonds is a great first step, and will hopefully enable private sector funding to be raised for some spaceport projects in the future,” said George Nield, chair of the Global Spaceport Alliance, a group that counts dozens of current and prospective spaceports among its members.
However, he noted enabling tax-exempt bonds alone are insufficient to secure funding for spaceport development.
“Historically, the most successful infrastructure projects have involved a combination of funding sources, including the private sector, state and local governments, and the federal government,” he said. “So, if we are serious about having the U.S. be a leader in space, the appropriate next step would be to provide at least some federal funding for spaceport infrastructure, including for non-federal spaceports, just like we do for infrastructure projects related to all other modes of transportation.”
Along those lines, the Global Spaceport Alliance has advocated for funding for spaceport infrastructure matching grants, a program the Federal Aviation Administration is authorized to support but which has not been funded for more than a decade. Nield said he was not aware of specific efforts to fund such grants, or other mechanisms for supporting spaceports, in pending appropriations bills for fiscal year 2026.
The bond language attracted some negative attention during debate about the bill. “Trump’s wedding gift to Bezos and birthday gift to Musk were tucked in the new budget bill the Republicans released overnight: A special new tax break for SPACEPORTS,” wrote Sen. Ron Wyden (D-Ore.) in a June 28 social media post.
It’s unclear that President Trump was aware of the provision and has not publicly mentioned it. Elon Musk, chief executive of SpaceX, and Jeff Bezos, founder of Blue Origin, would most likely be only indirect recipients of the benefits of the tax-exempt bonds through the improvements such bonds could fund at spaceports they use.
The standalone bill that enabled the tax-exempt spaceport bonds also had bipartisan support. The original bill last year was sponsored by then-Sen. Marco Rubio (R-Fla) and Sen. Ben Ray Luján (D-N.M.), along with Reps. Neal Dunn (R-Fla.) and Salud Carbajal (D-Calif.) in the House. Luján, Dunn and Carbajal all sponsored the version introduced in May along with Sen. Ashley Moody (R-Fla.), who succeeded Rubio in the Senate.
Some have also criticized the provision as providing a “billion-dollar” tax break. That figure is based on an assessment by the Joint Committee on Taxation, a nonpartisan congressional group, which estimated the break would result in a cumulative decrease in revenue for the government of $1.026 billion from fiscal years 2025 through 2034.
Most of the effects of the tax break would be in the outyears of the projection, including $204 million in 2034 alone, versus $0 in the current fiscal year and $11 million in 2026. The assessment did not discuss how it reached those conclusions.
