What is this tax you are talking about?

When exporting (taking items off the planet for sale or refining on a different planet) you pay a set amount of isk per item in tax.

Currently the tax is 15 isk per item if you export via your control center. If however you use a launch pad you only pay 10 isk per item in tax.

Please note that there is also a 5 isk tax imposed to import items to planets. (You need a launch pad to import)
