This change is part of their desire to add more ISK sinks to the game as noted during the 2012 Fanfest Economy presentation. During this presentation CCP showed that 50 T ISK was flowing in and 26 T out resulting in a net flow of +24 T ISK per month.
Adjusting a tax value is a very easy change with a large impact. More low-hanging fruit items to check off their list.
