What Is ICMS?
ICMS is a Brazilian state tax on the circulation of goods and services. It is similar to a sales tax in other countries.
The inquiry focuses on alleged fraud in refunds of accumulated ICMS credits. Companies sometimes have excess credits that they can transfer or refund.
Alleged Bribes
Prosecutors said the scheme involved bribes of 1% to 10% of the tax credits released. These payments allegedly went to officials to speed up credit releases.
Metrópoles reported that ex-tax official André Weiss received R$4.5 million (US$0.9 million) in cash. The tax authority said its actions had already recovered more than R$3 billion (US$590 million) in credits, fines and interest.
These conversions use the exchange rate of R$5.10 to the US dollar on 3 September 2026.
Companies Named
Metrópoles reported that companies said to have benefited from bribes include Farma Conde, Ipiranga, Sony Mobile, Casas Bahia, Assaí and Dia. These are retail and consumer goods firms.
Valor reported that Assaí, a supermarket chain, allegedly paid nearly R$53 million (US$10.4 million) to a lawyer to speed up credit releases. Assaí said it made no payments to public officials and authorized no improper advantages.
No Charges Filed
Rio Times Online reported that none of the three companies it identified were listed as defendants. Investigators described them as clients who received improper tax refunds.
Being named as a beneficiary is not the same as facing charges. No company has been formally charged with a crime, according to available reports.
Rumo’s Statement
Rumo said in a statement that it had opened an internal investigation that day.
It said the work is being carried out with support from independent external advisers.
It added: “As soon as it has access to the case file, Rumo will expand the scope of this investigation as necessary.”
It will stay with the São Paulo State Public Ministry and other authorities. It will help with the ongoing investigation.
Inquiry Origins
The inquiry began as a probe into alleged tax fraud in retail. It has now widened to include logistics and energy companies.
The investigation is still ongoing, and no final court judgment has been made. The names cited vary across different news reports.
What Happens Next
Rumo says it will cooperate fully with authorities. It plans to expand its internal probe once it sees the case file.
Other companies named have not yet commented publicly. The prosecutor’s office has not released an official list of all companies involved.
Context of the Case
The case involves alleged corruption in the São Paulo state finance department. Officials are accused of accepting bribes to release ICMS credits.
The investigation is separate from any criminal charges. It is a civil and administrative inquiry at this stage.
Reactions
Rumo’s statement was reported by Folha de S.Paulo. Valor and Metrópoles also covered the widening inquiry.
No company has admitted wrongdoing. The investigation continues, and more details may emerge.
Impact on Companies
The inquiry could affect the reputations of the companies named. Investors may watch for further developments.
But being named as a beneficiary does not mean guilt. The companies are not defendants, according to Rio Times Online.
Broader Implications
The case highlights issues with ICMS credit refunds in Brazil. It may lead to reforms in how states handle such credits.
For now, the inquiry is a reminder that tax systems can be vulnerable to corruption. Authorities are working to recover funds.

The tax authority’s actions have already yielded over R$3 billion (US$590 million) in tax credits, fines, and interest, per Metrópoles.
Key Figures and Their Roles
