This is a very complex question to answer and one that depends on many factors including your country of residence, your citizenship/s, your taxation status, which countries you happen to actually be staying at in a given year, your business arrangements and a bunch of other things. It is not as simple as Y and thus Z. All these platforms have to abide by taxation laws, EMIs included so yes you can bet CRS/FATCA is happening. Hire a specialist and setup your structures the correct and legal way to minimise your tax liabilities legally. That way everything is legal and you have nothing to worry about.
