WASHINGTON (REUTERS) - A loophole in the new US tax law could allow multinational corporations like Apple Inc to avoid paying billions of dollars in taxes on profits stashed overseas, according to experts.
Stemming from a Republican overhaul of international business taxes, the loophole involves the tax rates - 15.5 per cent or 8 per cent - that companies must pay on US$2.6 trillion (S$3.47 trillion) in profits they are holding abroad.
By manipulating their foreign cash positions, a determining factor under the new law, a US multinational could potentially save money by shifting profits to the lower rate from the higher one, according to Stephen Shay, a senior lecturer at Harvard Law School.
The savings could amount to more than US$4 billion in Apple's case alone, he said.
An Apple spokesman declined to speak on the record about Shay's analysis. US Treasury Department and Internal Revenue Service officials did not respond to Reuters' queries seeking comment.
"This is clearly the result of rushed legislation," said Shay, formerly a top Treasury Department tax official.
The sweeping Republican tax law was President Donald Trump's first major legislative triumph since he took office almost a year ago. Rushed through Congress, and approved over the unanimous opposition of Democrats, it took effect this month, delivering tax cuts and tax code changes that large, US-based multinationals had sought for years.
One of those changes was a one-time tax break on about US$2.6 trillion in profits that multinationals have socked away overseas in recent years under a "deferral" rule that let companies hold profits offshore tax-free, as long as the money was not brought into the United States, or repatriated.
There is no such deferral under the new law and accumulated overseas profits will now be taxed at either 15.5 per cent for cash holdings or at 8 per cent for more illiquid investments.
Both rates are far below the 35 per cent rate that would have been charged on repatriated foreign profits before the law was passed, and below a new 21 per cent corporate income tax rate.
To knock their taxes even lower, experts said, multinationals could have leeway to shift foreign earnings into the 8 per cent tax bracket and out of the 15.5 per cent bracket.
"Even before the legislation was unveiled in November, multinationals were planning to convert cash to non-cash assets, although it wasn't entirely clear what would constitute cash for this purpose," said Reuven Avi-Yonah, a leading tax expert at the University of Michigan Law School.
The loophole that makes the bracket-shifting possible involves a formula for calculating how much foreign earnings are subject to the higher tax rate. The benchmark is a company's foreign cash position, calculated as the greater of either the average of the past two tax years, or the cash balance at the end of the last tax year begun before Jan 1, 2018.
Companies would pay the 15.5 per cent rate on sums up to the calculated foreign cash position. Anything over that would get the 8 per cent rate.
Shay said some multinationals could reduce their cash positions, and the amount of money subject to the higher rate, through legitimate distributions including dividend payments.
He estimated Apple could have as much as US$289 billion in foreign cash at the end of its current fiscal year on Sept 30. Averaged across the last two tax years, the figure would be US$234 billion.
To avoid paying 15.5 per cent on the higher of those two figures, he said, Apple could distribute some of its cash through dividends or other means. Reducing its 2018 position by US$55 billion to the lower, two-year average would save the company more than US$4 billion in taxes, according to Shay.
The new law says transactions meant principally to reduce taxes due on foreign profits can be disregarded by US tax authorities. But tax experts said this anti-abuse measure does not apply automatically and that corporate tax lawyers could argue it does not apply to legitimate corporate actions.
