How much money are you making?
5 figures?
6 figures?
Basically the situation is difficult.
Do you never go home?
The countries you work from, are you on tourist visas?
Do you want to be 100% legal
Do you mind some grey areas?
Just be warned it is not as simple and easy as many websites that sell you IBC + bank accounts will lead you to believe. You cannot just say "I have a 0% tax jurisdiction corporation, I don't have to pay tax".
If you income is not huge, you can just go with your personal paypal to your home country bank who probably won't tax you as you are non-resident citizen and the countries where you travel to don't care.
For big money, it is not the best, but if for modest sums is fine (although perhaps not 100% legal, but not illegal, more like grey area. But depends on your home country (everything goes out the window if you are from US )
