“Vanuatu has previously been attractive as a retirement and investment destination for Australian citizens, largely due to its lack of an income tax, but there has been enhanced oversight in recent times by the Australian Tax Office of Australian citizens’ financial assets in Vanuatu. In that scenario, the IMF now proposes that an income tax could now be imposed, as it has been in other Pacific islands. Vanuatu’s domestic revenue, at 18.5 percent of GDP, is low relative to its Pacific island peers, suggesting scope to increase revenue. It is forecast that an income tax, levied on both employees and employers, could yield between 3 and 4 percent of GDP at modest tax rates.”
