Question: Why your tax in POCO 15%, can you set lower?
Answer: All our POCO have tax 5% from corp, more 10% take CONCORD.

NPC Tax
All Interbus Customs Offices, and Player Owned Customs Offices in High-sec, are subject to an NPC tax.
This tax is 10% for export and 5% for import. This is then in addition to whatever tax the player owner sets if the Customs Office is in High-sec.
The Customs Code Expertise skill can be trained to reduce this tax.
