For Winner2012 and Abrigado:
No, I give free advices to members of BHW - I just would like to remind you that a fiscalist hourly fees are from $400 to much more..
What I could do there: If you have a fiscal issue, I could give you clue to solve it.
But guy, be serious and don't expect me to work for you for free and spend days optimising your incomes

You've seen various posts with members giving their insights on SEO, but they don't offer you free backlinks, free onsite SEO, free content and free niche research.
Sometimes, I'll need more information: how much do you earn, which country do you came from, what are you doing currently. As I said, offshoring is not a game for very small incomes. If you're a student earning $300 a week, it will cost you more to offshore.
Antonha> why Dubai?
Abrigado > about Internet incomes:
Luxembourg has a very nice fiscal template for intellectual property incomes.. But you'll still have 4 to 5% tax - a pity compared to France heavy fiscality (33%). Moreover, as Greece is in Europe, you'll profit from non taxation agreement. See also my comment below
Antonha > about doing consultancy in the EU and facturation from Dubai.
It is a risky game. The first rule of offshoring is: Nobody talk about avoiding taxation. The second rule is: JUSTIFY offshore activities. All that mean: is it coherent for your business to create a subsidiary in Dubai? How can you justify it? Will your customers and suppliers agree to send payment to an emirati firm? They won't find it weird?
Moreover, as you said you live in the EU, I need to know more about your activities: is it a home consultancy job? (for instance, web hosting, offsite SEo, etc) Or will you physically be hosted by your client? (project management, auditor, and stuff like that). How much will you earn yearly?

Don't trust loosy websites saying that offshoring could solve all your fiscal issues. There is two schools of offshoring: the risky one - fraud, non declaration, pure tax avoidance - and the fair one - justify the usefulness of your offshore activities. I'm more from the second school - you still pay a (very) small tax but you're quiet, peaceful and won't fear a fiscal control.
