Before the 2017 Trump tax bill, Americans doing business and living offshore mainly used LLCs, because all profit remained untaxed as long as the profits remained offshore in the business. After the the 2017 Trump tax bill, using a CFC (offshore IBC) with an onshore C Corporation became far more tax advantageous, because the CFC is tax-free if created in a zero-tax country and the C Corporation then pays only 50% of the onshore tax rate (although slated to rise under the original tax bill -- and now also open to the full force of the socialist Biden Administration). Although you get taxed twice under that structure, once at the corporate rate and a second time when you withdraw dividends from the corporation, it is still more tax advantageous than operating a pass-through LLC. So, it depends upon many factors that mostly depend on your taxing country's tax codes.
