The Sao Paulo City Council approved the creation of a Parliamentary Inquiry Committee to investigate major debtors of state taxes [1, 2].

This move signals a crackdown on corporate tax evasion in Brazil's largest city. By targeting high-value debtors, the council aims to determine if companies are intentionally hiding assets or if oversight agencies have failed to collect owed funds.

The inquiry focuses specifically on the ICMS, a state-level value-added tax, and other state tributes [1, 2]. According to the council, the probe will target entities and economic groups that have accumulated debts exceeding R$ 150 million [2].

Legislators intend to uncover possible fiscal frauds and the concealment of assets [1, 2]. The committee will examine whether there was an omission of fiscal oversight by the relevant authorities, which may have allowed these multimillion-dollar debts to persist without resolution [1, 2].

There are conflicting reports regarding the exact date of the approval. Some records indicate the measure was passed during a plenary session on April 29, 2026 [1]. Other reports associated with the announcement on May 15, 2026, suggest the approval occurred more recently [2].

The investigation comes at a time when state and municipal governments are under pressure to increase revenue and ensure fiscal fairness. The committee has the authority to summon witnesses, and request documents to trace the flow of capital within the investigated companies [1, 2].

The probe will target entities and economic groups that have accumulated debts exceeding R$ 150 million.

The establishment of this CPI indicates a shift toward aggressive fiscal auditing of the private sector in Sao Paulo. By setting a high threshold for investigation, the council is prioritizing 'big fish' cases that could significantly impact state coffers. If the probe reveals systemic failures in tax collection or widespread fraud, it may lead to new legislative demands for stricter financial transparency and more rigorous oversight of state tax agencies.
