Some call the practice of moving a company abroad to avoid taxes "corporate inversion," while others deem these businesses “expatriate corporations.” Whichever term you prefer, the fact is that several successful American companies have moved their headquarters overseas in recent years to avoid hefty U.S. taxes.
1.Halliburton: Houston-based Halliburton, which offers a broad array of oil-field technologies and services to upstream oil and gas customers worldwide, announced the opening of a corporate headquarters in the United Arab Emirates city of Dubai on March 12, 2007. The company, which was once led by U.S. Vice President Dick Cheney, said that its relocation was part of a strategy that it announced in mid-2006 to concentrate its efforts in the Middle East in order to attract business.
2. Accenture: Consulting company Accenture is the Bermuda-based arm of the former Big Five accounting firm Arthur Andersen LLP, which is known for its involvement in the Enron Corp. scandal. Accenture has done pretty well for itself, garnering $662 million in contracts between Oct. 1, 2001 and Sept. 30, 2002. The company has argued that its operations should not be called corporate inversion because while Arthur Andersen was based in the U.S., Accenture never was.
3. Foster Wheeler Ltd.: The engineering firm Foster Wheeler moved its corporate headquarters to Bermuda in 2001, when the company was headed toward bankruptcy. Nearly 70 percent of Foster Wheeler's business comes from its international operations, and the move to Bermuda enabled the company to avoid paying taxes on income that it earned outside of the U.S. Most of the company's main offices remain in New Jersey.
