The successful move overseas from the USA does not come with a manual on how and what to do in all areas, especially Finance. The USA Expatriate has a completely different tax situation once they have moved outside the USA. It is very important that they retain a tax advisor who can “roll up their sleeves” with the Expatriate and make sure they take all deductions and exclusions and plan structurally properly so they legally minimize their tax liability. Mertz International LLC will work closely with you to get a plan in place to get all these items addressed.
