Medtronic’s Tax Lesson

Corporate inversions let businesses invest more in the U.S.

Medtronic’s pending acquisition of Covidien and adoption of Ireland as its legal headquarters teaches the economics of corporate inversion in one lesson. Here’s the trade: Medtronic agrees to call Ireland its legal home, and in return it gets to bring $1 billion or more into the U.S. without penalty.

That’s how much cash is sitting on Covidien’s books. True, it’s not nearly as much as Medtronic already has sitting in its own foreign subsidiaries. The Minneapolis-based medical technology firm currently holds $13 billion in cash abroad. But this Medtronic money is all subject to extra taxation once it crosses the U.S. border, unlike the Covidien money, which can be brought to the U.S. and invested without penalty. The same penalty-free investing goes for all of Covidien’s cash flow in the future.

We’ve written for years about how the U.S. has the highest corporate income tax rate in the developed world, and that’s an incentive for all companies, wherever they are based, to invest outside the U.S. But the current appetite for inversions—in which a U.S. firm buys a foreign company and adopts its legal address while keeping operational headquarters in the U.S.—results from the combination of this punitive rate with a separate problem created by Washington.

The U.S. is one of only six OECD countries that imposes on its businesses the world-wide taxation of corporate profits. Every company pays taxes to the country in which profits are earned. But U.S. companies have the extra burden of also paying the IRS whenever those profits come back from the foreign country into the U.S. The tax bill is the difference between whatever the companies paid overseas and the 35% U.S. rate.

The perverse result is that a foreign company can choose to invest in the U.S. without penalty, but U.S.-based Medtronic would pay hundreds of millions and perhaps billions in additional taxes if it wanted to bring overseas profits back to its home country. Medtronic’s work-around is essentially to become Covidien so it can more easily increase its investments in the U.S.—and the firm has promised to invest an additional $10 billion in America over the next decade.

Keep in mind that the money invested in corporations was once earned by someone who paid taxes on it. And it will be taxed again as dividends or capital gains. The point is that the U.S. government wants to tax U.S. business profits far more than other countries do. Inversions allow U.S. firms a level playing field that the U.S. tax code otherwise denies them.

There is no point to inversion unless a company wants to spend its cash in the U.S. This is one of the reasons why inversions are happening particularly among companies in biological sciences. The U.S. is still the world leader in medical innovation, despite the Food and Drug Administration, so companies want to invest here. Inversions will decline when there are fewer compelling opportunities in the U.S. and companies are content to invest in foreign workers, plant and equipment.

Medtronic emphasizes that it chose to do this deal for strategic reasons, believing the Covidien purchase will allow it to offer a broader product line of innovative devices. And successful companies don’t launch $43 billion acquisitions purely as a tax play. Medtronic’s global effective tax rate is typically 18%-20% depending on the tax year, compared to about 16% for Covidien. So the deal allows a reduction, not an elimination, of future tax bills.

The decision to move the legal address overseas is ironically the best news for Medtronic’s U.S. employees. Notice that even President Obama, while campaigning against “corporate deserters” and “unpatriotic” loopholes, doesn’t claim that American jobs are being lost. He knows U.S. workers win under these deals.

The losers are the President and the other politicians who receive less money to spend—though they’re not losing much. Kyle Pomerleau of the Tax Foundation notes that even if you believe the analysis from Congress’s Joint Committee on Taxation that implies inversions will cost the government about $19 billion over 10 years, “This is compared to the $4.5 trillion the corporate income tax will raise over the same period. That is 0.4 percent of our corporate tax base due to inversions.”

The truth is that Washington doesn’t have to lose at all. It could simply embrace a competitive tax system that encourages U.S. firms to invest in America. The economy would grow faster, employee incomes would rise, and the government would get more tax revenue.
