I have been looking into many jurisdictions recently; Bvi, cayman islands freezone, Hong Kong, Singapore.
None of them provide what Dubai offers.
Take bvi for example, if you run it from UAE. You have to pay 9% tax.
Any jurisdiction that offers 0% tax free and even traditional bank, you still have to pay 9% taxes in UAE as long as you are resident of UAE.
Maybe someone will come and say move to like Thailand or Paraguay run bvi from there at 0% tax free. But you will get terrible emi and never real banking.
So the only way left is stick to UAE︀ and pay 9% taxes, maybe lower tax a bit with high salary and that's it.︁
I believe it would be better if we discuss tax optimization tips than to look︂ for other jurisdiction.
