Revenue Identifies Billions in Tax Evasion with Artificial Intelligence
The Federal Revenue announced on September 16, 2025, during the LIDE Public Security Seminar in São Paulo, the detection of R$ 11 billion in tax evasion. The amount was identified with the help of artificial intelligence platforms.
Auditor Sonia Accioli made the announcement and highlighted the increasing use of technology in combating fraud. In addition, she emphasized that the Revenue strengthens digital oversight with AI resources.
According to Accioli, the Revenue already uses artificial intelligence to identify suspicious cryptocurrency transactions. Likewise, the systems can map complex networks of companies. In some cases, the Revenue even anticipates irregularities before they become consolidated frauds.

The auditor also emphasized that technology does not only act punitively. On the contrary, AI also stimulates voluntary compliance and avoids legal disputes, which enhances oversight efficiency.
Artificial Intelligence as an Ally in Oversight
The use of artificial intelligence has been transforming how irregularities are combated. Thus, through large-scale data cross-referencing, the Revenue can:
- Track complex digital operations quickly;
- Detect suspicious movements with cryptocurrencies swiftly;
- Recognize irregular business networks efficiently;
- Prevent fraudulent schemes before they consolidate.
As a result, artificial intelligence increases the efficiency of oversight, reduces the risks of tax evasion, and strengthens the compliance environment.
Ministry of Justice Creates Cyber Network with R$ 50 Million
At the same event, the national secretary of Public Security, Mário Sarrubbo, announced the creation of the Cyber Network. The system connects all specialized police stations in digital crimes in Brazil.
To structure the initiative, the Ministry of Justice allocated R$ 50 million. This investment ensures that state units have access to data extraction software, such as Cellebrite. This tool already assists digital investigations in various countries.
According to Sarrubbo, “crime advances when it is not clarified.” He also stated that technology has become essential to provide quick responses, integrate security forces, and prevent the financing of criminal organizations in the digital environment.
Technological Advances and Future Challenges
The integration of the Federal Revenue with artificial intelligence systems and the creation of the Cyber Network show that the government bets on technology as a key tool. Thus, the focus is on combating tax evasion and facing digital crimes.
While the Revenue strengthens its actions against billion-dollar tax frauds, the Cyber Network creates a unified front to tackle digital crime. This type of crime, by the way, grows in sophistication every year.
On the other hand, experts warn that technological advancement requires continuous oversight. Furthermore, they request transparency in the use of tools and a commitment to individual rights. This way, the government can balance efficiency and citizen protection.
