Lee Introduces UNtaxed Act to Stop United Nations from Taxing Americans

December 4, 2025

WASHINGTON – U.S. Senator Mike Lee (R-UT) introduced the UNtaxed Act to block the United Nations (UN) from imposing taxes on American citizens or businesses. President Trump successfully postponed a vote on the UN’s proposed global carbon tax scheme earlier this fall, and the UNtaxed Act will support the President’s agenda in Congress to ensure Americans are never subject to taxes imposed by international bureaucrats. Republican Study Committee Chairman August Pfluger (R-TX) introduced the House version of this bill.

“The United Nations has come up with yet another way to take American tax dollars for their woke climate guilt,” said Senator Mike Lee. “President Trump stood up to the UN to block their global carbon tax, and it’s time for Congress to back him up and put America first. Americans are already the UN’s biggest cash cow – we shouldn’t be forced to pay for anything we don’t agree with, period.”

"The International Maritime Organization buckled under pressure from President Trump and Republicans who unapologetically stood up for American interests. However, this fight isn't over," said RSC Chairman August Pfluger. "This legislation would kill their global carbon tax scheme permanently by depriving all US funding to any UN agency that attempts to impose a tax on the American people and ensuring Congress has a say in all taxes, fees, and penalties on American citizens or companies. America is the largest contributor to the UN, and we should not bankroll an organization that seeks to tax our people and undermine our economy. Unelected international bureaucrats will not dictate to the American people."

Background

A subsection of the United Nations has been attempting to force a global carbon tax for the past several years. Earlier this fall, President Trump persuaded the UN to postpone their vote on this burdensome violation of American sovereignty. The UNtaxed Act supports President Trump’s America first agenda with legislative force to keep foreign bureaucrats away from American tax dollars.

The UNtaxed Act would:

  • Prevent the United Nations or any of its affiliated bodies, including specialized agencies and commissions, from imposing any taxes, tariffs, fees, or penalties on U.S. citizens or businesses or requiring that such levies be paid. 
  • Permits such measures to be implemented only if they are part of an existing agreement with the United States that has been ratified by the U.S. Senate.
  • Prohibit the appropriation or allocation of funds for contributions to the United Nations or any of its affiliated bodies if those funds would be used to impose or enforce a global carbon tax.
