As an official of an international institution, her salary of $467,940 (£298,675) a year plus $83,760 additional allowance a year is not subject to any taxes.
The former French finance minister took over as managing director of the IMF last year when she succeeded her disgraced compatriot Dominique Strauss-Kahn, who was forced to resign after he faced charges – later dropped – of sexually attacking a New York hotel maid.
Lagarde, 56, receives a pay and benefits package worth more than American president Barack Obama earns from the United States government, and he pays taxes on it.
The same applies to nearly all United Nations employees – article 34 of the Vienna convention on diplomatic relations of 1961, which has been signed by 187 states, declares: "A diplomatic agent shall be exempt from all dues and taxes, personal or real, national, regional or municipal."
Where exactly does one go to sign up for a U.N. gig?
