You can't have that because each EU country has different incentives. Some countries tax salaries more than capital, other let you reduce your capital gains or offer a flat tax in certain circumstances.

I forgot to mention, but if this EU Inc gets then created who gets the capital gain tax? Should it be divided in 27 or should it prorated to where you lived or where your customers live?

Don't get me wrong, I would love to see this happen but just like most of the things in the EU, it would become a nightmare to manage and add even more bureaucracy.

It's like VAT collection. We have to rely on middle-man companies to do the proper collection because most countries have vastly different rules regarding VAT.

As a business owner every minute I spend on paperwork is a minute less I spend on my business.
