Tax Reform and Technology: Companies must adapt systems to ensure compliance

Technological adaptation is one of the challenges in the new fiscal landscape

By Fabiana Soares

The Tax Reform will significantly impact the way companies organize and manage their tax processes. Changes in tax rates, the method of tax calculation, and the unification of certain taxes require a restructuring of companies' accounting and tax systems.

Such a complex transformation will not be possible without the implementation of technologies that help companies maintain compliance with the new rules. It is necessary to prepare to meet the requirements, avoiding errors that could result in penalties and financial losses.

Technology for adapting to new requirements

Tax authorities have been well-equipped for some years now for instant cross-checks, which requires companies to conduct prior checks with great efficiency.

The use of advanced technologies for management is, therefore, already indispensable. Companies typically turn to technological solutions to automate tax calculation processes, monitor legislative changes, and submit declarations.

During the transition to the Tax Reform, systems will need to ensure compliance with both existing and new requirements, which will gradually be incorporated into daily routines. This involves the need to accurately calculate taxes, adjust parameters for the use of tax credits, properly classify transactions, and comply with accessory obligations.

The split payment model, which will be introduced, where the payment of the tax owed is automatically separated from the principal value of the transaction, is also an area of focus concerning billing system adjustments.

In this regard, it is essential to rely on a partner who can keep up with the pace of changes, ensuring agility in the implementation of updates and requirements of the new tax model.

Why is it necessary to prepare now?

Because changes are already taking place. In addition to Complementary Law No. 214/2025, official acts and communications have been published with instructions, adjustments, and validation rules, such as technical notes and classification tables.

The IRS has also launched the Consumer Tax Reform Pilot, which began on July 1st. The progress of this project needs to be monitored, as it is expected that the tests conducted, which will be shared with the public, will contribute to the improvement of the technological solutions needed for the implementation of the CBS.

In other words, there is already a vast universe to be explored, and it is necessary for software to already be adapted to reflect this existing informational base. Companies that start now will gain security and predictability.

Although the transition will officially begin in 2026, many of the changes require long-term planning to avoid the risk of non-compliance. The impact of tax errors can be significant, resulting in penalties.

Companies will need to invest in tax intelligence, automation, and constant updates to keep up with this long and complex process that promises to be the transition to the Tax Reform.

The role of specialized accounting

Specialized accounting advisory remains relevant in this environment. The Reform requires a keen eye on the nuances of the incorporated rules, and accounting professionals will be indispensable in interpreting the standards and supporting the configuration of systems according to the specificities of each sector.

With the Reform, accounting will take on the responsibility of validating operations in both regimes (the current one and the new one, during the transition) and providing guidance on necessary changes in procedures to comply with the new regulations. The accounting advisory should also assist in identifying tax planning opportunities, helping to reduce the tax burden in a legal and efficient manner. The integration of technology and technical knowledge offers the best foundation to ensure compliance and seize opportunities.
