A uniform transaction tax regime for the EU?

1709 Blog reader John Walker posted the following question as a comment on that blog, but it seems to me that it's more likely to receive an answer on this one. He writes:
"Australia used to have a very complex sales tax regime (for example the tax on tissue paper in a box was much more than the tax on the same tissue paper if wrapped around a toilet roll). Australia in the year 2000 introduced a uniform Goods and Services Tax (GST). GST largely replaced a complex and hard to see system, levied by both the Federal and the individual state governments, with a uniform tax levied at the same rate on every transaction. (there are some exceptions, but nobody's perfect)

Many of the EU's copyright' levies are transaction taxes; the nexus between the consent of a right holder and payment to the same right holder is clearly severed.

Doesn't the EU have any policy about aiming for a reasonably uniform transaction tax regime?"
Can any reader give John some assistance on this point?
