Further commenting on the planned inversion by Johnson Controls and Ireland-based Tyco Hillary Clinton said, "These efforts to shirk U.S. tax obligations leave American taxpayers holding the bag while corporations juice more revenues and profits ."  

The statement continued. "I have a detailed and targeted plan to immediately put a stop to inversions and invest in the U.S., block deals like Johnson Controls and Tyco, and place an 'exit tax' on corporations that leave the country to lower their tax bill."

Johnson Controls will be moving its headquarters to Cork in Ireland and in so doing would become the latest major U.S. company to carry out a so-called tax-inversion after drug giant Pfizer Inc structured such a deal with Irish firm Allergan Plc last November.

The tax benefits involved in the Johnson Controls and Tyco deal are reportedly not to the samce scale as those of the Pfizer deal, the news of the Johnson Tyco deal was certainly sufficient to raise some eyebrows amongs politicians in a U.S. presidential election year.

Vermont Senator Bernie Sanders, Clinton's opponent for the Democratic Presidential nomination, also criticised the deal by calling it a disaster for American taxpayers. Reuters also say that others saw it as an opportunity to also highlight what they argue are the weaknesses of the U.S. tax system.

"Absent comprehensive tax reform that includes shifting to a territorial tax system with base erosion protections, Congress ought to examine viable bipartisan solutions that will effectively target and combat inversions and not tip the balance to tax-driven foreign acquisitions of U.S. firms," said U.S. Senate Finance Committee Chairman Orrin Hatch, a prominent Republican.

Also according to Reuters when asked, the White House declined to comment on the latest so-called tax-inversion deal by a major U.S. company, but said legislation was needed to close the loophole.
