for a example German customer with a FreeZone Company and bank account in UAE + Residency VISA in UAE (with real Utility Bill), the AEOI will be between UAE and UAE and not between UAE and Germany.
If the FreeZone Company has a bank account outside UAE (for example in Belize), the AEOI will be between Belize and UAE .
The AEOI is between the bank and the Tax Authority except for US citizens (FATCA).
But question is how to get a utilility bill? and what would this setup cost?
For me not importen to make business in dubai and i sell only apps ?︀
