Victor Boris Santos Maciel, a tax specialist and business advisor, explains that before thinking about tax reductions or more complex tax planning strategies, many companies need to take an essential step: clearly understanding how they are calculating and paying their taxes. This is where a tax diagnosis becomes decisive for a company’s financial health.
In practice, a tax diagnosis works like an X-ray of the company’s tax operations. It assesses tax regimes, calculation bases, product and service classifications, compliance with ancillary obligations, and the integration between accounting, tax, and financial areas. By organizing this information, the company gains clearer visibility into bottlenecks, overpayments, and—most importantly—risk areas.
In this article, learn more about tax diagnosis, how it works, and how it can transform practices within your company.
What Is a Tax Diagnosis in Practice?
Although the term may sound technical, a tax diagnosis is a very objective process. It begins with an analysis of the adopted tax regime, checking whether the company is correctly classified and whether this choice is still the most suitable for its size and operating model. Next, the calculation bases of the main taxes are reviewed to identify recurring errors or misinterpretations of legislation.
Another relevant point is verifying the correct use of tax credits, especially for non-cumulative taxes. Many companies fail to take advantage of legitimate credits due to procedural flaws or lack of system integration. As Victor Boris Santos Maciel points out, this is one of the factors that most affects tax efficiency and, consequently, financial performance.
How Does the Diagnosis Reveal Invisible Risks?
One of the greatest benefits of a tax diagnosis is making visible risks that typically go unnoticed in day-to-day operations, explains Victor Boris Santos Maciel. These risks may be linked to incorrect tax classifications, improper use of tax incentives, failures in document issuance systems, or even contracts that are poorly structured from a tax perspective.
When these issues are not identified, a company may operate for years under a false sense of compliance—until an audit or external inspection reveals inconsistencies that lead to fines, interest, and administrative or judicial disputes. In this sense, the diagnosis acts as a preventive tool, significantly reducing the likelihood of financial surprises.
Diagnosis as the Foundation of Tax Planning
Many tax planning strategies fail precisely because they are not based on a solid diagnosis. Without knowing the company’s actual tax reality, any attempt at reorganization can be ineffective or even create new risks. Therefore, the diagnosis should be seen as the initial stage of any tax efficiency project.
Based on this mapping, it becomes possible to evaluate changes in tax regimes, process reviews, corporate restructurings, and even adjustments in supplier contracting or service delivery models. When these decisions are made using concrete data, they tend to generate more consistent and sustainable gains.
Victor Boris Santos Maciel emphasizes that the diagnosis also helps prioritize actions. Instead of trying to fix everything at once, the company can focus on areas with the greatest financial impact or highest risk exposure, making the process more efficient and aligned with business needs.
Why Do Growing Companies Need This X-Ray?
Companies in a growth phase face specific challenges. The pursuit of new markets, team expansion, and operational scaling often capture management’s attention, while tax aspects take a back seat. However, it is precisely at this stage that tax risks tend to intensify.
A tax diagnosis allows companies to track this evolution and adjust processes before problems become structural, demonstrates tax planning specialist Victor Boris Santos Maciel. It also helps ensure that growth is supported by adequate margins and a tax burden compatible with the business’s reality.
Companies that adopt this type of periodic review are better able to sustain expansion with greater predictability, preventing operational gains from being eroded by unexpected tax costs. Moreover, the organization resulting from the diagnosis strengthens governance and facilitates relationships with investors, financial institutions, and strategic partners.
Diagnosis as a Management Tool, Not Just a Tax One
A tax diagnosis goes far beyond a technical tax review. It functions as a management tool that supports strategic decisions, reduces risks, and improves financial performance. By providing a clear view of the company’s tax reality, this process lays the groundwork for more effective planning and sustainable growth.
With a structured approach, as highlighted by Victor Boris Santos Maciel, the diagnosis shifts from a reactive action to an integral part of management routines, contributing to more organized, predictable companies that are better prepared to face regulatory changes and market challenges. Therefore, for those seeking consistent results, starting with a diagnosis is undoubtedly an essential step.
