I phrased that out wrong, my source of profits was from Poland, I'd relay the funds to
Estonia and then transfer them out to UAE.
I've done same with Poland - Czechia - Malta,
Germany - Estonia - UAE etc.
Making complex stuff on paper is what I like doing hence I always involve way more companies into the mix than even necessary because that way I know nobody will unveil what the heck I was doing and/or I'll long be gone.
I agree, Belgium might be different but if you're able to make some intra-community transfers before and make it all look legit you won't get in trouble in Belgium at least. Some less strict nations you can look into are Estonia, Czechia,
Slovakia, Romania, Bulgaria or Hungary too
