Section 911 of U.S. tax law provides certain tax benefits to persons who report foreign earned income.  To be entitled to the benefits, an individual must have a “tax home” abroad, provided that he or she does not have an “abode” in the U.S.  A recent summary opinion by the Tax Court illustrates the difference between those two terms.  Rusudan Shervashidze and Philip R. Hirschfeld explain.
