A recent Bloomberg article details Google’s corporate structure, which moves revenues to subsidiaries in low-tax countries such as Ireland, Bermuda, and the Netherlands, with the result of reducing corporate taxes in those countries that are their largest markets: the United States and United Kingdom.
Google’s not alone, of course. Both Facebook and Microsift use similar tax structures, and a US Treasury measure to tax monies moved between international subsidiaries was halted by what we’ve come to know as the “political process”:
Treasury officials, who estimated the policy change would raise $86.5 billion in new revenue over the next decade, dropped it after Congress and Treasury were lobbied by companies, including manufacturing and media conglomerate General Electric Co., health-product maker Johnson & Johnson and coffee giant Starbucks Corp., according to federal disclosures compiled by the non-profit Center for Responsive Politics.
The report by Bloomberg is worth a read.
