Federal Revenue Reinforces Data Cross-Referencing and Expands Oversight Against Omission of Income and Medical Errors in Declarations
Declaring the Personal Income Tax (PIT) in 2025 requires even more attention. This is because the Federal Revenue updated the data cross-referencing mechanisms and expanded the oversight of the information provided by taxpayers. With recent changes in tax legislation and stricter rules, errors become more apparent and generate severe penalties for those who fail to comply with the rules.
Omission of Income Dominates the Most Common Errors
The Federal Revenue released an official report in February 2025 showing that over 90% of the errors recorded in 2024 occurred due to omission of income. Consequently, many taxpayers failed to report amounts of rents, pensions, or dependent income. The problem arises from both negligence and unawareness of the obligation.
Tax law specialists state that this error has become the main reason leading taxpayers to fall into the tax net. This process requires detailed proof and can result in fines of up to 75% on the owed amount.

Unemployment rises again to 5.8% at the beginning of 2026, raising alarms about the end of temporary positions and its impact on the Brazilian job market.

Document organization can cut invisible costs in small businesses, a simple step that prevents waste, rework, and losses in daily operations.

Chinese giant worth nearly R$ 4 billion that manufactures cables for electric cars, solar energy, and robotics wants to open a factory in SC.

Many employers do not know, but the law guarantees domestic workers a 25% increase in salary during trips, 50% for overtime, 20% for night shifts, and 17 additional benefits that can lead to labor lawsuits if not paid.
Medical Expenses Require Proof for Deduction
Another critical point arises with medical expenses. For these costs to qualify as deductions, the taxpayer must provide supporting documents showing payment and the provision of the service. Without receipts or invoices, the Federal Revenue disregards the amounts, classifies them as inconsistent, and applies sanctions.
Regulations published in the Official Gazette in January 2025 reinforce this requirement to curb fraud and increase transparency in medical deductions.
How the Federal Revenue Identifies Inconsistencies
Since 2019, the Federal Revenue has been using an artificial intelligence system that cross-references declared data with records from banks, health plans, real estate agencies, and financial institutions. In March 2025, the system received an update and began identifying inconsistencies in seconds.
Thus, when the declared data does not match official records, the system generates an immediate alert. In this case, the taxpayer must provide clarifications, and in severe situations, faces heavy fines.
Measures to Avoid Errors in Declaration
In light of this scenario, experts recommend simple and effective strategies to reduce risks:
- Review all sources of income before submitting the declaration.
- Include dependent income, which many forget.
- Organize receipts and invoices for medical expenses throughout the year.
- Use the updated official program from the Federal Revenue, released in March 2025.
- Keep track of tax legislation, published in the Official Gazette.
By taking these measures, the taxpayer increases the security of their declaration and avoids falling into the tax net.
The Federal Revenue’s Goal with the New Rules
In a press conference held in April 2025, the special secretary of the Federal Revenue highlighted that the agency’s goal is to reduce the number of audited taxpayers by 20% by 2026. He stated that the intention is not only revenue-oriented but also educational, aiming to raise awareness among the public about the importance of maintaining the declaration faithful to reality.
However, specialists remind that, despite the transparency, the rigidity of the data cross-referencing system presents an additional challenge for taxpayers, especially those who do not organize their financial information throughout the year.
The Future of Income Tax Declaration
With the increasing digitization and application of advanced analysis algorithms, the coming years are expected to bring even more rigor. The Federal Revenue is likely to expand data integration with public and private institutions, which practically makes it impossible to omit income or include expenses without proof.
Therefore, Brazilians need to adopt organizational and transparency practices to remain compliant with the law. After all, simple errors, like omitting income or failing to present medical receipts, can lead to not only fines but also lengthy and exhausting legal processes.
And you, do you believe that Brazilian taxpayers are prepared to deal with increased oversight in 2025, or should the Federal Revenue invest more in guidance and tax education?
