French citizens will contribute an extra €1.60 on their property insurance policies to help finance a fund for victims of extremist attacks which have recently hit the country.
The measure comes into force on Sunday and requires policy holders to contribute €5.90 instead of €4.30.
French government officials said in October when they revealed the scheme that about 90 million insurance policies are floating the fund, which currently has reserves of €1.45bn.
More than 200 people have died in France as a result of terror attacks over the last 20 months.
The Bastille Day truck attack in Nice which left 86 dead this summer cost between €300m and €400m, approximatively the same as the November 13 attacks in Paris, which killed 130 people.
