Similarly to income, tax also has to be reported separately for each type of income on which tax was paid.  Income tax withheld from wages is shown as TAX SALAIRE BRUT of the Bulletin de Salaire.
For US tax purposes, “Contribution Sociale Généralisée” (CSG) and the “Contribution pour le Remboursement de la Dette Sociale” (CRDS) are now eligible for the Foreign Tax Credit under the Internal Revenue Code or the U.S.-French Income Tax Treaty.
Taxes on unearned income may be withheld by the payor (i.e.,bank withheld income tax from dividends) or you may owe tax upon completion of tax assessment form. Report each type of tax paid during the filing year in the respective section of our Questionnaire, even if it applied to income received in prior years.
Wealth tax (Impôt sur la fortune)  is not an income tax. It can be deducted on your US tax return as a part of itemized deductions. Report this tax in section Main > Deductions of our Tax Questionnaire.
