Kocieniewski won Pulitzer Prizes in 2012 and 2013. He authored a series entitled, “But Nobody Pays That,” examining the efforts made by companies to reduce taxes and how the
tax system should be revised, which was awarded the 2012 Pulitzer for explanatory reporting. The following year he wrote an exposé about Apple's tax avoidance strategies as part of the New York Times series. That series, which was produced by 10 Times reporters in all, received the 2013
Pulitzer Prize for Explanatory Reporting, for its “penetrating look into business practices by Apple and other technology companies that illustrates the darker side of a changing global economy for workers and consumers.” The jury added that Kocieniewski's work had “penetrated a legal thicket to explain how the nation’s wealthiest citizens and corporations often exploited loopholes and avoided taxes. Kocieniewski has also been the recipient of awards from: the
New York State Bar Association, the
National Association of Black Journalists and the March Sidney Award for his
General Electric Company exposé.” ==Recognition==
