WASHINGTON (Reuters) - A European Commission order requiring Apple Inc <AAPL.O> to pay Ireland $13 billion euros ($14.5 billion) in unpaid taxes on Tuesday drew swift rebukes from the Obama administration and lawmakers in Congress, while reigniting calls for U.S. tax reform.
The White House and the Treasury Department, which enforces federal tax policy, warned that U.S.-EU economic relations could be affected by the European Commission's ruling that Apple had received illegal state aid under its agreement with Ireland.
Business groups protested. The Business Roundtable, which represents U.S. chief executives, called the decision "an act of aggression" against a law-abiding U.S. company and a sovereign government.
Members of both parties in Congress pointed to the stunning decision as evidence that the U.S. tax code should be rewritten to give American companies an incentive to bring home some $2.1 trillion in U.S. corporate profits held abroad. But there was no sign that lawmakers were any closer to bridging the substantial divides that have prevented agreement up to now.
"Above all, this is yet another reason why we need to fix our tax code," House Speaker Paul Ryan, the highest-ranking elected Republican, said in a statement. "Today's decision should be a spur to action."
Apple was found to be holding over $181 billion offshore, more than any U.S. company, in a study published last year by two left-leaning nonprofit groups: Citizens for Tax Justice and the U.S. Public Interest Research Group Education Fund.
"This is yet another example of why we need to reform the international tax system to ensure these revenues come home," said Senator Charles Schumer, the chamber's No. 3 Democrat.
Even the European Commission voiced indirect criticism of the U.S. tax code, suggesting that Washington could require Apple's Irish operations to pay larger amounts of money to the U.S. parent to finance research and development, which would increase Apple's U.S. tax bill.
Former Senator Carl Levin, a Democrat whose investigation of U.S. corporate tax avoidance was cited by European regulators, blamed the U.S. Internal Revenue Service for failing to challenge Apple's overseas arrangements.
Republicans and Democrats in the Senate have discussed plans to encourage the repatriation of U.S. profits abroad.
But House Republicans hope to move broader legislation next year that would cut the U.S. corporate tax rate from 35 percent to 20 percent and adopt a "territorial" system that would exempt the overseas earnings of U.S. companies from U.S. taxation. Democrats have dismissed that as a massive tax giveaway.
Other critics in Washington warned that Tuesday's European Commission move would encroach on U.S. government jurisdiction and ultimately add to the federal deficit.
"We are concerned about a unilateral approach ... that threaten(s) to undermine progress that we have made collaboratively with the Europeans to make the international taxation system fair," White House spokesman Josh Earnest told reporters.
U.S. Representative Kevin Brady, Republican chairman of the House Ways and Means Committee, called the decision "a predatory and naked tax grab".
Apple and Ireland said they would appeal the EU decision. But some analysts said the ruling, if upheld, could change the calculus that has kept U.S. corporate money overseas if it means higher taxes in low-tax European countries like Ireland.
"The scheme of U.S. multinationals parking money offshore indefinitely, taxed at zero, may be coming to an end," said Steven Rosenthal of the Tax Policy Center research group.
Online retailer Amazon.com Inc <AMZN.O> and fast-food company McDonald's Corp <MCD.N> already face probes over taxes in Luxembourg, while coffee chain Starbucks Corp <SBUX.O> has been ordered to pay up to 30 million euros ($33 million) to the Dutch government.
