FAQPage Schema

How do I calculate French income tax with the 2025 tranches and quotient familial?▼

French income tax for 2025 is computed by applying the progressive barème tranches to your taxable income divided by your quotient familial shares, then applying decote and plafonnement rules to get the final IR amount.

How does the PFU flat tax compare to the barème for investment income?▼

The PFU applies a 30% flat tax on investment income, while the barème uses progressive tranches. The Skill computes both PFU and barème scenarios to determine which option yields the lower tax liability for your situation.

Can I calculate crypto gains and RSU vesting tax using 2025 French tax rules?▼

Yes, the Skill handles crypto gains and RSU vesting scenarios under 2025 French tax rules, computing the applicable IR, prélèvements sociaux, and CEHR contributions with deterministic step-by-step calculations.

What tax scenarios are supported for married households with children and PER deductions?▼

The Skill supports married households with children by applying quotient familial plafonnement, and processes PER pension deductions by subtracting them from taxable income before computing the IR across 2025 tranches.

Does this French tax calculator handle IFI and non-resident tax regimes?▼

Yes, the Skill computes IFI for wealth tax purposes and applies non-resident tax regimes, generating structured outputs with RNI, QF, prélèvements sociaux, and CEHR calculations using 2025 rules.

What input format do I need to provide for French income tax computation?▼

You provide a foyer.json file containing household composition and income details, or you can use the included sample inputs to immediately run a deterministic 2025 tax calculation with step-by-step IR sequencing.
