It is the Socialdemokraterna in Switzerland that is driving the legislative change which means an inheritance tax of 50 percent will be paid on all assets over 50 million francs, equivalent to approximately 600 million Swedish kronor, when someone dies and the survivors are to inherit.
The revenue from the inheritance tax is proposed to be used to finance measures to combat climate change.
Even though the parliament and the government are against the proposal, the rules for direct democracy in Switzerland now require that a referendum be held on the plan. It will take place on November 30, the government announced on Tuesday.
Those who are critical of the inheritance tax fear that it will cause rich people, who are major taxpayers, to leave the country.
