DuPont is among the 68 big U.S. corporations that a new report identifies as having paid no state income tax in at least one of the last three years, according to Bloomberg News.
In fact, Wilmington-based DuPont is one of three companies that paid no state income tax in each year between 2008 and 2010, says the 71-page report by the Institute on Taxation and Economic Policy. Bloomberg said a DuPont spokeswoman declined to comment.
The Washington, D.C.-based research group is backed by labor unions, Bloomberg says. The study (a PDF is here) looked at 265 companies among the Fortune 500 that were profitable in all three years. In all, those companies paid state income taxes equal to 3 percent of their profits, or half the average statutory rate.
In other local business doings, Inovio Pharmaceuticals said it has completed a public offering that raised net proceeds of $3.7 million for the Blue Bell developer of synthetic vaccines. Inovio will use the money for expenses of clinical trials and R&D.
