No, Belize has zero tax. I meant the tax authorities. If you won't get problems from your local authority or your customers won't get problems from their local authorities when getting an invoice from Belize then Belize is a good option for keeping the director private. But again, as said before, get a nominee.
Is the privacy of your director really your only concern? I don't think so. So better tell us which benefits you want to have from your offshore company. In my opinion a Seychelle (and Belize, too) company is not a good choice for EU citizens, all transaction to these countries will be flagged.
