France vs California: take-home pay comparison
French PAS + CSG-CRDS + ~22% social charges against California federal + state + FICA — Bay Area relocation comparison.
A common comparison for French tech and finance professionals considering Bay Area roles. France's payroll stack is one of the heaviest globally: PAS income tax (0–45%) on top of ~22% effective combined employee social charges (CSG, CRDS, retraite, Agirc-Arrco, assurance maladie). California's combined federal + state + FICA tops out at ~52% above $626k but starts much lower — an entry-level $60k Californian retains far more net than an entry-level €55k Parisian.
At mid incomes the gap widens further in favour of California, driven by the persistent French social-charges floor that has no ceiling at mid-income levels. The cost-of-living delta (Bay Area is one of the most expensive metros globally) is not captured here — interpret the native net values, not the FX-adjusted delta.
