Dubai might still be ok if you have a non-UAE company and pay yourself a salary (below GAAR limits) so the profit isnt above 375k AED, or have a nominee employee/director in some other country.
But yes, the whole dealing with reporting to UAE authorities is not great. I ve understood that for VAT the UAE Federal Tax Administration is very strict and not very understanding. Anyway, still not clarified how things will turn out, so one might as well start looking for a home base to replace/complement Dubai.
Ideas:
-Subsaharan Africa (except South Africa) - there is a lot of freedom in economies where the informal sector dominates, are cash based, streets dont have names or numbers, there are︀ no personal tax returns, the government dont keep track of residents very much. There are︁ downsides as well of course, when you have to deal with the government it can︂ be a pain, anything imported is expensive (cause imports are heavily taxed, just like it︃ used to be in Europe 100 years+ ago), and quality of goods and services can︄ be low.
On the upside you got enormous economic opportunities, the population and the economies︅ are growing fast, competition is limited, and Africa effectively filters out "tourists". Also lifestyle-wise it︆ can be really great living in a beautiful place, with inexpensive live-in domestic staff, chauffeur,︇ nurses for baby/children, personal trainer etc
-Some Caribbean island: Cayman, Bahamas, Barbados, St Martin, DR,︈ St Barths, Curacao, Turks and Caicos (Im still doing research here)
-A Pacific island: Seems︉ both Palau and Vanuatu totally dont tax foreign income even if you manage a foreign︊ company from there. Yes, bit far away, small, bad timezone, but still, would be cool︋ a month or two a year.
-Latin America: Heard Panama City is like Dubai but︌ for (slightly) poorer people. Panama has made it harder to get residency though, but still︍ possible. Paraguay seems great in terms of not so difficult to get residency, and good︎ tax wise too. El Salvador and other central american countries with territorial tax seem interesting️ too, even if it's not so clear tax wise if you manage a foreign company for there
