The Sanders Corporate Tax Reform Plan
http://www.commondreams.org/views/2015/12/04/sanders-corporate-tax-reform-plan
Senator Bernie Sanders Corporate Tax Dodging Prevention Act is summarized in an April 14 Senate Budget Committee blog post, (Sanders is the ranking member of that committee.)
1) Ending the rule allowing American corporations to defer paying federal income taxes on profits of their offshore subsidiaries.
This would immediately bring in up to $620 billion of federal tax revenue currently owed on offshore profits but deferred. (It would also make available in the US more than $2 trillion of corporate profits that have been kept offshore, which could be reinvested or distributed to shareholders.)
Additionally, this would increase federal tax revenue by as much as $90+ billion each year thereafter.
These amounts are based on a report from Citizens for Tax Justice (CTJ) and the U.S. PIRG Education Fund, titled Offshore Shell Games.
A second look at the amounts owed by these companies , detailed in a letter to Congress titled, 24 International Tax Experts Address Current Tax Reform Efforts in Congress sets the amount this would bring in at about $900 billion over 10 years.
2) Closing loopholes allowing American corporations to artificially inflate or accelerate their foreign tax credits.
A current loophole allows corporations to claim foreign tax credits for taxes paid on foreign income even if that income is not subject to current U.S. tax. This closes that loophole.
3) Preventing American corporations from claiming to be foreign by using a tax-haven post office box as their address.
