Hikashop with a fix Price and no Tax Rule

-- url of the page with the problem -- : www.kkspshop.com/

-- Joomla version -- : Joomla! 3.6.5 Stable
-- PHP version -- : 5.4.43

Hey just wanted to ask,

how can i add a fix price to a product with no tax rules ?

I see i can add a new Group (example: Distributor) and then add a new price via ACL and then assign the Price to a Group.

But how can i do that for example for a Distributor, with no extra VAT ? And doesnt matter where their are located.

Regards

Pierre
