The title of this thread is about taxes and best places, not girls and best place, if that is what you are looking for I think you guys are on the wrong forum
I thought I would make a friendly reminder, but it seems some people don't get it. Please stick to the topic and avoid turning a thread into another topic.
But one of the requisites of OP is a place that gives him the ability to get good-looking, young side chicks.
I know, who said I wasn't going to sell that asset within a 5 years timeframe? (e.g: Leonardo di caprio).
Well, first of all, girls are not an asset but a liability, and second, you cannot sell them!
But now, to answer your question, I think you should really consider SEA. It's cheaper than Europe, and it's easier to get young women if this is important for you. In fact, in countries such as Thailand or Vietnam, it's a national sport to have young side chicks (I don't have one, by the way, just talking about my friends).
The reality is that it's extremely hard in Europe for someone in their 30s/40s to date stunning girls in their early 20s (unless you're really, really rich and know where to look for them), but in Asia this is not a problem, and you'll be surprised at the quality of girls you can get in Asia compared to Europe, especially if you're older or not as attractive (my case: in Europe I don't exist for most women, in Vietnam young girls wink at me in the street and flirt with me constantly).
But I don't know how it would be for someone who is already attractive in Europe; they can probably date actual models here in SEA. A completely different world. Just make sure you're white (don't get tanned) and always muscular, so hit that gym hard and eat chicken breasts with rice like there's no tomorrow.
Also, international schools and other expenses: in SEA, your money will go much further.
Taxation: in SEA, most countries don't care about foreign income. In Thailand, for example, only remitted income is taxable, so you'll pay little to no tax and have to deal with little to no tax declarations as well. You won't even need a tax advisor. The people at the revenue department will help you with your paperwork once a year so that you pay your $200 remitted income tax.
Healthcare: excellent, especially in countries such as Thailand, Vietnam, or Malaysia, and very affordable prices. You can get insurance for you and your whole family for cheap, and always get treated quickly in the best private hospitals.
I really recommend Thailand, Vietnam, and Malaysia (this last one slightly less, especially if you want side chicks).
If not possible and you want to stay in Europe and have to choose within those 3 outlined options, I agree with what others have said; Romania is probably your best option.
