America's biggest corporations are increasingly funneling
profits earned in the United States to tax havens around the
globe, depriving the United States Treasury of anywhere from
$10 billion to $20 billion in lost tax revenue each year,
according to a new study.
The study, to be published today in the trade journal Tax
Notes, says that United States multinational corporations
shifted $75 billion in domestic profits last year to no-tax
and low-tax foreign havens like Bermuda and Ireland.
The study's author, Martin A. Sullivan, said that legal
loopholes and tax credits could mean in theory that no taxes
are owed to the United States government on the shifted
income. But he wrote that the shifting is more likely to
result in annual tax losses to federal coffers of $10
billion to $20 billion. He said yesterday that at least some
of the transfer probably occurred through questionable tax
shelters.
In a related study, published by Tax Notes earlier this
month, Mr. Sullivan concluded that that profits reported by
American multinational companies from their foreign
subsidiaries, and not from their operations based in the
United States, soared 68 percent since 1999, to $149 billion
last year. The earlier study said that the rise in foreign
earnings was not accompanied by any gain in real economic
activity in the tax havens, suggesting that multinationals
were increasingly using offshore tax shelters to shield
earnings.
