EU doesn't collect any taxes. EU get all its budget money from the member states, based on negotiations between the members, that is, how much each member pays to the EU budget. The member states then set their own taxes to whatever levels they like. EU doesn't have a common taxation policy, although sometimes standardization of certain taxes has been tried to bring into the negotiations, but I believe those negotiations have always failed completely. So, it's up to each member state how much they tax their poor citizens.
