France and Luxembourg signed a new double tax treaty on income and capital in late March.  Ratification by the end of the year is anticipated.  The new treaty reflects the current post-B.E.P.S. environment.  Among other things, the residence definition is tightened, the test for the existence of a permanent establishment is loosened, real estate funds face higher withholding tax, a credit method is adopted to avoid double taxation.  Christophe Jolk, Attorney at Law, Paris, explains the implications for investors.
