Medtronic Inc., famous for heart devices, also has a less-well-known distinction: It's one of the 30 U.S. corporations with the most money parked offshore.
The Fridley-based medical device maker holds $20.5 billion overseas, just one notch below Wal-Mart Stores Inc. with $21.4 billion, according to a report released Thursday.
Medtronic is one of more than a dozen Minnesota corporations in the joint report by Citizens for Tax Justice and U.S. Public Interest Research Group, which are calling for an end to the abuse of offshore tax havens.
The study uses 2013 data to examine the number of subsidiaries Fortune 500 companies have in countries regarded as tax havens, such as Bermuda and the Cayman Islands, and the amount of money they report holding offshore in general.
Medtronic, for instance, has 37 subsidiaries in so-called tax haven countries.
The authors say they can't determine exactly how much of the money companies keep offshore is in tax-haven countries vs. other overseas locations where the companies have operations. However, there's evidence that a significant portion comes from the widespread use of accounting techniques to book profits outside the United States to avoid paying the 35 percent U.S. corporate income tax on it.
The authors point to a Congressional Research Service study showing that in 2008 U.S. multinationals collectively reported 43 percent of their foreign earnings in five small tax-haven countries, countries that accounted for just 4 percent of their foreign workforce and 7 percent of their foreign investment.
Such practices reduce federal revenue by $90 billion a year, the report said.
