IMF Chief, Christine Lagarde, told the Greeks to pay their taxes and, by implication is telling everyone to stop dodging, minimising, avoiding, evading or downright stealing taxes from the nations that create the common wealth.
Like many international organisations supported by tax revenues (IMF, WHO, World Bank, the EC etc) the staff do not pay tax in their salaries. So, Madame Lagarde pays no tax, a fact siezed upon by disgruntled off-shore tax evaders. She may of course recommend a change to this protocol.
Will the righteous anger of the artful dodgers stop the new official determination to collect the taxes? No - I think not. With up to $18 trillion washing around off-shore - contrasted to a $9 trillion "global mountain of debt" on-shore - threatening to bankrupt major economies; I guess the responsible authorities will press ever harder to collect what was and is due - for repatriation to, and reinvestment in, the countries of origin.
AS AN EXPERIENCED TAX-PLANNER MY ADVICE IS - MOVE YOUR MONEY ON-SHORE.
