The Declaration of Specific Regimes (DeRE) is not simply a new file to be transmitted. To calculate IBS and CBS under specific regimes, an institution needs to connect registration data, chart of accounts, trial balances, investments, securities, and tax classifications distributed across different systems and teams. It is in the gaps between these sources that discrepancies, unresolved issues without a designated owner, and reprocessing close to the deadline arise. This is the operational problem that Evertec’s DeRE solution solves.
Meeting the obligation requires a workflow that coordinates data, validations, and responses among tax, accounting, operations, and technology teams. The solution organizes this journey from registration configuration to transmission, providing a shared view of each reporting period.
Why DeRE compliance requires integration
DeRE is the ancillary obligation used to calculate IBS and CBS for financial service providers, healthcare plan operators, and entities that operate prediction contests. Its scope includes different operations and structures, such as supplementary pension entities, banks, SDCs, payment institutions, brokerage firms, DTVMs, finance companies, credit unions, development agencies, insurance companies, consortium operators, and funds.
The official schedule provides for table events beginning on October 1, 2026, monthly periodic events on November 15, 2026, and the remaining events on January 1, 2027. Meeting these requirements involves more than generating an XML file at the end of the process. Institutions need to organize registration data, chart of accounts, tax classifications, monthly data, and responsibilities.
This challenge is connected to the technological adaptation brought about by Tax Reform, in which integration, data quality, and governance become part of regulatory compliance.
How the guided tax journey of the Evertec DeRE solution works
The solution structures the monthly cycle into three stages, with progress indicators and feedback for the operator. This allows teams to identify what has been completed, what remains pending, and where a discrepancy needs to be addressed.
1. Enter
The first stage imports taxpayer information, the Commented General Chart of Accounts, the trial balance for the reporting period, financial investments, and debt securities. The registration sequence organizes the taxpayer, chart of accounts, accounting accounts, and their links to the applicable tax classifications.
2. Consolidate
After the data is entered, the solution validates the structure and content of the files, identifies conflicts, and flags accounts without a tax code. Contingency editing makes it possible to address PGCC data, trial balances, investments, and securities when an operational correction is required.
Validations take place before transmission, helping to reduce the risk of rejections and correction cycles with the Brazilian Federal Revenue Service. This control becomes especially relevant in a routine already marked by accounting changes and new reporting rules.
3. Send and monitor
In the final stage, the solution signs and transmits the events, monitors batches, and records protocols and receipts. After receiving a response from the Brazilian Federal Revenue Service, the information and calculation records can be returned to legacy systems, preserving the history of the monthly close.
Controls that support the operation
Transmission settings centralize keys, communication parameters, and event signatures. Domain tables and taxpayer registration data can be maintained manually or imported according to the process defined by the institution.
A single dashboard displays the status of the reporting period, pending items, and schedule milestones. Business teams can maintain tables, registrations, and corrections within established permissions, reducing operational dependencies on IT. The technical team remains responsible for integrations, infrastructure, security, and support, but no longer needs to be involved in every routine adjustment.
The result is an operation with greater traceability over what was entered, what was validated, what needs correction, and what has already returned from the Brazilian Federal Revenue Service environment.
Key features of Evertec’s DeRE solution
For customers within the Evertec ecosystem, native integration simplifies connections with the sources already in use. The architecture also makes it possible to integrate other systems and legacy platforms, adapting implementation to the institution’s technology environment. This flexibility is part of a broader discussion about architecture as a strategic capability in the financial market.
The solution was designed to keep pace with the evolution of DeRE layouts, rules, and phases. This is relevant because the technical documentation continues to receive updates. By combining technology, integration, flexible architecture, operational autonomy, and regulatory evolution, Evertec positions the solution to support the obligation throughout its different stages without limiting the institution to a single system design.
What should you prepare for implementation?
The solution can operate as Evertec SaaS or on-premises. The choice should take into account the institution’s IT, security, and operational guidelines. Before the project begins, it is necessary to define secure connectivity with the Brazilian Federal Revenue Service and internal systems, provide certificates and communication parameters, and map registration, PGCC, trial balance, investment, securities, and closing data sources.
Users, profiles, responsibilities for credentials, certification, initial monitoring, and ongoing support must also be defined. This assessment prevents an infrastructure decision from leaving gaps in the operational process.
For institutions that already deal with different legal requirements and banking-sector reporting obligations, the decision should consider three points: data dispersion, the volume of manual interventions, and the ability to trace each change through to closing.
