Tax inversions are in the news, but they are not new. They are a form of tax avoidance that has been used before and can only be stopped by changing the rules that allow them. It’s believed that the practice of tax inversions began in the 1990s though nobody is quite certain of its exact origin.

Today, tax inversions have again mushroomed, giving the government an opportunity to look closely at the corporate tax rate and the reasons why they are avoiding paying taxes. Investment News discusses the issue:

“Part of the attraction of getting out of the U.S. tax net is the fact that the U.S. imposes a tax on all income the company makes whether it is earned within or outside of the U.S. That is not how most countries compute income.

“There also has been a focus on the U.S.’s 35% tax rate on corporations. Again, the U.S. is at a comparative disadvantage with other countries because we tax corporate earnings twice: once to the corporation and then again as the owners (shareholders) receive payments of those after-tax earnings.

“Inversions are just the latest strategy employed by U.S. corporations trying to get out from under the hefty tax burden levied on corporate earnings.

“In the 1980s, U.S. companies made an effort to eliminate the corporate level of tax by turning themselves into master limited partnerships. The government, scared by this trend, in 1987 passed IRC Section 7704, which limits the type of income MLPs can earn. Not surprisingly, new MLPs could not operate ‘active’ businesses.

“In 2002, Accenture PLC moved to Bermuda and later Ireland to save on U.S. taxes. By 2004 there was legislation that treated companies that simply shifted their addresses out of the country as domestic for tax purposes.

“EXCEPTIONS

“However, there were several exceptions, including if they had ‘substantial’ business in their new home, or if they merged with a foreign company whose shareholders ended up owning at least 20% of the combined firm. Not surprisingly, we see these current inversions conforming to those rules.

“At the same time we see some companies inverting, we see other corporations converting to lower their tax bill. As an example, Weyerhaeuser Co. was a tax-paying corporation until it converted to a real estate investment trust a few years ago. A REIT is akin to a mutual fund, but it owns real estate instead of stocks or bonds. Like a mutual fund it pays no tax as long as the REIT’s income is distributed each year.

“But, like the inversions of today, the shareholder paid a tax toll for going from a corporation to a REIT. Weyerhaeuser had to distribute whatever earnings it had that had not already been paid out as dividends. Although the shareholders received little cash, they had income of more than $26 per share by virtue of holding Weyerhaeuser through the transition.

“At least these taxpayers paid the toll to enjoy a tax-favored income stream as Weyerhaeuser continues to cut down trees; income received from harvesting trees is considered a long-term gain. Because Weyerhaeuser, like all corporations, treats all gains as ordinary income, this benefit was lost in the corporate form. Before conversion, Weyerhaeuser paid a 35% tax on gains from cutting trees and then its shareholders paid another tax as dividends were paid. A 20% long-term-gain rate brings the total tax paid to the U.S. government to 48 cents on the dollar. After conversion, taxpayers now are able to keep 80 cents on the dollar.

“We find it ironic that at the same time the government is up in arms about inversions, it is being more expansive with companies that want to spin off or convert to a zero tax environment.”
