Hardy was a known opponent of the solidarity tax on wealth (French: "impôt de solidarité sur la fortune"; ISF). In 2010, she defended the tax shield put in place by the government of Nicolas Sarkozy and, in 2012, caused controversy when denouncing François Hollande's tax program amidst the presidential elections, telling "Paris Match": "I believe that most people do not realize the tragedy that the ISF causes to people in my category. I am forced, almost 70 years old and ill, to sell my apartment and move out." This prompted her son Thomas Dutronc to write on Twitter: "But no mom, don't worry I'll invite you over to my place just in case...". Annoyed by the extent of her remarks, the singer later complained: "First, contrary to what has been written, I did not speak of the 'tragedy' of people who pay the ISF. The tragedy is the people who are losing their jobs because of offshoring and the crisis, and about whom we hear about every day in the newspapers. Then I never said I was going to be homeless. It's absurd. And even less that I was going to go into exile!"
