President Donald Trump likes to say he’s bringing in trillions of dollars in investments from foreign countries, but a provision in his tax cuts bill could cause international companies to avoid expanding into the United States.

The House-passed version of the legislation would allow the federal government to impose taxes on foreign-parented companies and investors from countries judged as charging “unfair foreign taxes” on U.S. companies.

Known as Section 899, the measure could cause companies to avoid investing in the U.S. out of concern they could face steep taxes. The fate of the measure rests with the Senate — setting off a debate about its prospects and impact.

A new analysis by the Global Business Alliance, a trade group representing international companies such as Toyota and Nestle, estimates that the provision would cost the U.S. 360,000 jobs and $55 billion annually over 10 years in lost gross domestic product. The analysis estimates that the tax could cut a third off the economic growth anticipated from the overall tax cuts by Congress’ Joint Committee on Taxation.

“While proponents say this punitive tax hike is intended as a retaliatory measure against foreign governments, this report confirms that the real victims are American workers in states like North Carolina, South Carolina, Indiana, Tennessee and Texas,” said Jonathan Samford, president and CEO of the Global Business Alliance.

The Global Business Alliance was among the groups that signed a letter on Monday warning of the consequences of Section 899 to Senate Majority Leader John Thune of South Dakota and Senate Finance Committee Chairman Mike Crapo of Idaho, both Republicans.

The Investment Company Institute, representing financial firms, said the provision “could limit foreign investment to the U.S. — a key driver of growth in American capital markets that ultimately benefits American families saving for their futures.”
