THE BURNED OVER DISTRICT

Multinational corporations, especially in the current financial environment, have billions of dollars in offshore profits they want to repatriate. But they will do any and everything they possibly can to avoid paying taxes on those profits.

At the White House on Dec. 15, business executives asked President Obama for a tax holiday that would help them tap more than $1 trillion of offshore earnings, much of it sitting in island tax havens.

The money -- including hundreds of billions in profits that U.S. companies attribute to overseas subsidiaries to avoid taxes -- is supposed to be taxed at up to 35 percent when it’s brought home, or “repatriated.” Executives including John T. Chambers of Cisco Systems Inc. say a tax break would return a flood of cash and boost the economy.

What nobody’s saying publicly is that U.S. multinationals are already finding legal ways to avoid that tax. Over the years, they’ve brought cash home, tax-free, employing strategies with nicknames worthy of 1970s conspiracy thrillers -- including “the Killer B” and “the Deadly D.”

Merck & Co Inc., the second-largest drugmaker in the U.S., last year brought more than $9 billion from abroad without paying any U.S. tax to help finance its acquisition of Schering-Plough Corp., securities filings show. Merck is also appealing a federal judge’s 2009 finding that Schering-Plough owed taxes on $690 million it had earlier brought home from overseas tax-free.

The idea of a tax break producing a flood of cash to boost the economy is one of those fraudulent memes being floated in the endless game played by the multinationals to avoid as much as they can.

“The current U.S. international tax system is the best of all worlds for U.S. multinationals,” said David S. Miller, a partner at Cadwalader, Wickersham & Taft LLP in New York. That’s because the companies can defer federal income taxes by shifting profits into low-tax jurisdictions abroad, and then use foreign tax credits to shelter those earnings from U.S. tax when they repatriate them, he said.

They’re aided by a cadre of attorneys, accountants and investment bankers in the tax-planning industry -- such as a panel of KPMG LLP tax advisers who held forth in a chilly hotel ballroom at a Philadelphia conference last month. There, they discussed a series of techniques for multinationals to return cash from overseas while avoiding or deferring the taxes.

KPMG tax advisers Kevin Glenn and Tom Zollo used slides to describe several methods. One diagram resembled a schematic from the Manhattan Project. Another strategy would require certain “bells and whistles” to convince regulators of an actual non-tax business purpose, Glenn explained.

Such maneuvers reflect a decades-long cat-and-mouse game. As regulators and lawmakers tighten the rules, companies seek new, legal methods for getting around them. One of the techniques the KPMG advisers discussed was in response to loophole-closers Congress passed in August to address a projected $1.4 trillion federal budget deficit. The changes will make it harder for companies to manipulate the credits they get for taxes paid overseas.

“Some of the best minds in the country are spent all day, every day, wheedling nickels and dimes out of the tax system,” said H. David Rosenbloom, an attorney at Caplin & Drysdale in Washington, D.C., and director of the international tax program at New York University’s school of law.

Corporations need an AMT just like us little people.
