Just as water flows downhill, action to prevent aggressive tax planning flows from (i) the O.E.C.D. in its B.E.P.S. Action Plan, especially Action 5 applicable to no or nominal tax jurisdictions (“N.T.J.’s”) to (ii) the E.U. Code of Conduct Group (“C.O.C.G.”), in its scoping paper identifying nine relevant activities and economic substance criteria for N.T.J.’s to avoid the E.U. blacklist, to (iii) the N.T.J.’s, themselves, in steps taken to police economic substance requirements of local law. The B.V.I. heard the message and has implemented a robust information reporting system for relevant entities. In their article, Joshua Mangeot, a partner in the B.V.I. office of Harneys and Kiril Pehlivanov, a member of the investment funds and regulatory team in the B.V.I office of Harneys, explain the effect of the B.V.I. economic substance regime on companies and limited partnerships registered in the B.V.I. and provide practical guidance for compliance and reporting.
