Under the agreement signed today, inheritances would be taxed based on where the recipient resides, not where the deceased lived, as used to be the case.
France, which taxes inheritance progressively up to 45 per cent, compared to Switzerland's maximum of 7 per cent, hopes the new agreement will make it harder for people living in France to evade taxes.
France is one of a growing number of cash-strapped governments trying to find tax cheats squirrelling away cash in Swiss accounts.
Both countries' parliaments must approve the agreement.
