The French Constitutional Court finalized the “exceptional surcharges” to levy on corporate income of the French largest companies. This exceptional surcharges apply to French companies or branches that are subject to corporate tax, and have gross revenue exceeding €1 billion. The surcharge rate will be 15% for the companies with gross revenue exceeding €1 billion. The companies with gross revenue exceeding €3 billion will have to pay an “additional contribution” equal to 15%., i.e., these taxpayers will be subject to a total surcharge of 30% of their gross corporate tax liability. This rule for exceptional surcharge applies on the corporate income tax for the financial year closed between 31 December 2017 and 30 December 2018.
