No New Taxes

Increased taxes are coming with the Inferno patch.

Market tax has been increased from 1% to 1.5% as a part of our initiative to keep the EVE economy healthy.
Inferno Patch Notes

This change won’t be too detrimental for me. I do fear for the smaller trader that has to work with <5% margins.

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.
