Georgia is certainly no competition for the UAE. Lifestyles are completely different (Georgia offers nothing in this regard). Georgia is all but cosmopolitan; it is a tiny place in the middle of nowhere.
Tax preferences in Georgia are for small entrepreneurs; otherwise, you pay more than in the UAE.
The danger of creating a PE in Georgia is very high, and their
"foreign-sourced income" definition is more than blurry. Careful with that country! There is a reason why it only attracts very small businesses (and Russian draft dodgers).
If you only live on passive income and it is really "foreign sourced" (note their definition), Georgia is ok tax-wise. Note: You have to stay 183 days in every rolling 12-month period to make that work.
But again, if it is only passive
investment income, you can also just live in the UAE, where life is much more luxurious and offers a gazillion times more options.
