Facebook France is going to pay $125 million (€106 million) in back taxes according to business magazine Capital — Facebook confirmed the agreement to both Capital and Reuters. French tax authorities raided Facebook’s offices in Paris in 2012 and later opened an investigation on unpaid taxes covering activities between 2009 and 2018.

According to the investigation, Facebook allegedly optimized its effective tax rate in France by funneling sales to other subsidiaries in different European countries.
