Franck Le Mentec and Vincent Desry Discuss Tax Raids with Les Echos Le Parisien Services
Paris partners Franck Le Mentec and Vincent Desry were recently interviewed by Les Echos Le Parisien Services on the topic of tax raids.
They discussed the circumstances under which France’s National Directorate of Tax Investigations (DNEF) may initiate a raid—such as the discovery of false invoices or intentional accounting omissions—and outlined the legal procedures that follow. The conversation also covered how investigations are conducted, particularly in cases involving complex tax fraud schemes, which may carry criminal implications. Franck and Vincent shared practical guidance for individuals or companies subject to such actions: keep detailed notes, never leave investigators unattended, and review all requested documents carefully. They also emphasized the serious consequences of obstructing an investigation.
