Ce n’est pas un chiffre que je tire de mon chapeau. Je le tire en fait d’une réponse sur Quora, à la question : “What is it like to date or marry a fashion model?” (qui l’eut crû ?), dans lequel la personne qui répond à cette question explique être sortit avec une top model pendant 4 ans, et que celle-ci devait économiser environ 45% de ses rentrées d’argent pour payer ses taxes. Je fais un billet ici car j’entends souvent des gens me vanter les USA comme une terre où les taxes sont (quasi) nulles, comparé à la France. Certes, la situation ne pourra peut-être pas être pire qu’en France, mais je trouve que de voir ce chiffre de 45% me permet de relativiser tous ceux qui me diront que les taxes sont très faibles.

Le passage en question :
She would get huge checks every few months but on a highly irregular and totally unpredictable basis, as she was always a contractor she would be responsible for handling her own tax withholdings (which she would never do), so she would always have a huge unexpected tax bill in the spring which she would freak out about and each time she was only saved in the nick of time by the next check that (luckily) came in the mail. I was brought up to be pretty good with money so I tried to help her keep her finances in order, but she never understood why she should put away ~45% (“That’s like half my earnings!”) from every check to account for the self-employment taxes that would be due at the end of the year. After being together for a couple years, I got a good sense of how much she earned over time and tried to explain to her what she should try to think of as her average income stream over time and to keep weekly expenses in line, but it was something she just wasn’t very interested in.
Bah, on dit souvent qu'en France tu commence à te remplir les poches après le mois de mai.
Et pas seulement pour les auto-entrepreneurs.
