"April 24, 2002 Identical Letters Sent To:
Senator Max Baucus
Senator Charles Grassley
Representative William Thomas
Representative Charles Rangel
Dear .....:
American-based companies must pay tax to the IRS on income earned in other nations. This "worldwide" system of taxing corporate income is very anti-competitive, causing many companies to give up their U.S. charters and instead become foreign-based companies. These "expatriations" are legal, but have become controversial. Lawmakers likely will choose from two options in deciding how best to respond to this development.
The rest of the letter is available right here.
It is worth the read and in particular, note who signed the letter. The National Retail Sales Tax Alliance joined the Coalition for Tax Competition after the letter was sent.
