Guys, I don't understand you.. if $6k+ legal expense and $2k per year is expensive, why you bother yourself with these tax residencies? Just pay tax in your country. It should be cheaper overall.
I think legit residency in such country as United Arab Emirates will set you back at least $10k per month (including rental, legal︀ expense, fligths and etc.). So, it's worth calculating if really you would pay more than︁ $10k per month in taxes in your country...?
Any other reasonable residency would also cost︂ a lot..
I don't think it's realistic to "fake" residency these days. Tax inspectors can︃ get flight records, credit card data, phone movement data, even discount, loyalty cards records... and︄ etc. I mean if you want to change residency you really have to be ready︅ to live in that country. Rent a flat, apply for fitness club, spend time, eat︆ in restaurants, pay every shop and restaurant with credit card to have presence records...
Sooner or later you will be asked to provide these evidence. If no evidence, you will︇ be still taxed in your country of origin...
Tax inspectors would even collect your social︈ media data , facebook, instagram. If you make photos in your country of origin and︉ post it. They will use it as proof of still living in country of origin.︊ They also track participation in events and conferences..
To be realistic about tax residency you︋ have to make sure you have more social, personal and economic ties with UAE than︌ with your origin country.. Simple incorporation and residency card is not enough for tax residency.︍
