Unfortunately, the U.S. is one of few countries that actually have limited liability companies (LLCs). Therefore, there is no international equivalent of the Madrid Protocol (international patent) for LLCs. However, many countries have entities similar to an LLC, but just named differently. Despite this, each foreign country will have its own laws concerning foreign ownership of domestic entities. This will require you to research each country’s pertinent laws.
It’s worth noting that doing business abroad can complicate compliance reporting requirements when tax time comes. This is because the U.S. taxes its citizens on their worldwide income, regardless of where the money was made. The U.S. permits a credit (the “foreign tax credit”) against U.S. tax for taxes paid to other countries on income sourced to such other countries, so long as the effective rate paid to the other country does not exceed the effective rate paid to the U.S. on that same income.
