President Trump and congressional lawmakers are not the only ones interested in collecting taxes on global profits that American corporations are hoarding overseas. European regulators, knee deep in a campaign to stamp out tax avoidance, have their own plans for that money.

Last week, for instance, the European Commission billed Amazon for $293 million in unpaid taxes in Luxembourg, arguing that the country’s failure to collect the tax amounted to an illegal state subsidy. It also took Ireland to court for not following up on the $15.2 billion tax bill imposed on Apple last year.

“The Europeans are targeting U.S. dollars overseas that the U.S. believes should be taxed here,” said Dave Camp, a former Republican representative from Michigan who was chairman of the House Ways and Means Committee and the author of an unsuccessful tax overhaul in 2014. “We have to address this problem before the Europeans get there first.”

The rulings on Amazon and Apple — which those companies are disputing — are byproducts of a race among governments to lure corporate giants to their shores in the hunt for new sources of revenue. That cutthroat competition is the reason that 73 percent of Fortune 500 companies have a subsidiary in a low-tax haven, according to the Institute on Taxation and Economic Policy. (Their latest report, done in conjunction with the United States Public Interest Research Group Education Fund, was released on Tuesday.)
