I read all the above.
I learned nothing.
I reside in the region.
I know around 50 or so traders in UAE.
Nobody pays tax. Everyone understands and is 100% certain their profits are tax free.
Most have been in Dubai for 10+ years.
A few just come i the recent crypto bull market purely to cash out tax free and settle down in Dubai.
What the exact legal rules are, I expect there will never be a clear answer.
I expect it's also by design.
If you know 50+ traders living/working in UAE I'd be interested to discuss with some of them. In particular, It would be quite valuable to know if they have consulted a lawyer (not only a tax advisor) rather recently, and which decrees/rules the latter relied their position on.
Please note that this thread is not about taxation, it is about licensing and compliance. Though, if you/your friends have sources justifying an exemption (for full time traders) I'm more than interested.
