A tax consultancy based in Teresina (PI) has come under scrutiny for receiving large payments from Banco Master and JBS, which amount to R$ 6.6 million and R$ 11.3 million respectively, during the period from August 2024 to July 2025. This consultancy, named Consult Inteligência Tributária, is linked to Kevin de Carvalho Marques, the son of Supreme Court minister Kassio Nunes Marques. According to a report from the Financial Activities Control Council (Coaf), which was revealed by the newspaper O Estado de S. Paulo, this association raises serious concerns regarding conflicts of interest and potential illicit financial activities.

The Coaf's report indicates that the consultancy's transactions between 2024 and 2025, which included R$ 281.6 thousand paid in 11 transfers to Kevin Marques' law firm, were disproportionate to the declared income of the consultancy, which stood at merely R$ 25.5 thousand. This discrepancy has led Coaf to classify these transactions as incompatible with the financial capacity of the consultancy, suggesting that the funds may have illicit origins. The report has sparked discussions within Brazil about governance, transparency, and the ethical obligations of public officials, especially concerning their family dealings in the business sector.

The implications of this revelation could be significant for both the individuals involved and Brazilian judiciary integrity. Questions have arisen about the capability of the Supreme Court to maintain impartiality in its rulings, especially with a minister whose family is linked to a consultancy receiving questionable payments. The public's trust in the judiciary could be at stake, urging further investigations into the finances not only of Kevin Marques but also the broader implications for public office accountability in Brazil.
