Belgian authorities have seized €65 million ($76 million) in a French investigation into suspected aggravated tax fraud and money laundering involving the U.S.-based consulting firm McKinsey, French and Belgian prosecutors said on Friday.

McKinsey did not immediately reply to an emailed request for comment.

The National Financial Prosecutor’s Office (PNF) opened the investigation in March 2022 following a French Senate inquiry into the growing influence of private consulting firms on public policy.

McKinsey offices were searched in May 2022, while witnesses and suspects were questioned in 2025 and 2026, the statement said.

The PNF also sought assistance from Brussels’ Prosecutor’s Office.

Belgian authorities seized €65.2 million, corresponding to 96% of the tax loss estimated by French prosecutors.

The preliminary investigation continues, the prosecutors said.
