You want to make use of VPS and some sort of tunneling when you connect to the VPS. From there you setup the companhy, EMI and what else you need in order to receive the money! Then you do a similar setup just with a NEW SETUP to setup the second company with darks, emi etc. - now you make sure the VPS and / or tunnel you rae using is destroyed in the world wide web. You want to make use of clouds for that purpose or some of the very few available real offshore VPS's.
That's how you can forget about tax authorities, CRS and all this s**t! When the day comes where you want to spend the money you hold in the EMI's or even bank accounts (complicated but well possible to do) then you either travel to a destination to where you get your debit card send, you may spend there some weeks for this to work.
OR you make use of a mail forwarding service where you can pickup the card, don't get it send to you! You want to visit the service provider and pick up the package. You want to get that somewhere far away from you even in another country.
So you can be sure nothing goes wrong. If you have large (really large amounts) you want to setup the whole thing different, but it's even more costly and complicated and I won't reveal how to do that here since it's already going far to wide.
Think out of the box, do proper research when you do things and don't fall for cheap and shitty solutions, that the key to success in all of this.
You may alreayd have seen the difference with the simplest account opening when somone that knows his stuff do it and if you do it yourself, you need to learn and try, retry and try again to be good in setting this up.
