Q3/2025
Tax Reform Transition Period (2026–2033): A specific module has been developed to align with the official timeline of the Brazilian tax transition. The system supports hybrid tax calculation, considering the rules for the coexistence of the current and new tax systems during the 2026–2033 period. The implementation includes support for calculation and audits with dual rates and rules, as well as pre-configuration for testing, simulations, and tax impact comparisons. These features aim to provide proactive support for clients' tax planning, reduce errors and inconsistencies during the coexistence period, and improve confidence in adopting the system as a compliance tool for the transition.
New Features: The module has been enhanced with new features to increase the system's control and flexibility. The main implementations are:

- Value editing in the tax calculation (Projection): Allows clients to manually edit figures to increase or decrease the amounts paid, with options to view changes, remove edits to revert to the original value, or insert other simulation values.

- Limit per root CNPJ on tool usage to align with sales agreements.

- Creation of an electric energy report based on EFD-Contribuições.

- Inclusion of the Tax Reform trial balance template on the Upload screen.

- Adjustments to the Price Comparison Filter.

- features aim to offer greater control and flexibility in Tax Reform analyses.

New NF-e Layout: The NF-e layout has been updated to include fields for IBS and CBS.
