Qualifying for the Foreign Earned Income Exclusion using the bona fide or physical presence tests can be a tricky , especially for expats who just moved overseas. Some expats are better off taking the Foreign Tax Credit (Form 1116) instead of the exclusion on Form 2555. However, once you start using one method, you cannot switch to the other method without first asking the IRS’ permission to change your accounting methods. You may want to consult with a tax professional who has experience in preparing expat tax returns.
