IBS and CBS: is your SAP operation prepared?

Brazil’s new tax model requires attention to electronic tax documents, credits, tax calculations, settings and integrations within SAP.

The introduction of IBS and CBS represents one of the main changes brought by Brazil’s Consumption Tax Reform.

For companies, the challenge is not only to understand the new taxes, but also to adapt processes, systems, electronic tax documents and operational routines to a new model of tax calculation and compliance.

In an SAP environment, this preparation needs to be addressed with a systemic view. IBS and CBS may impact purchasing, sales, tax receiving, billing, tax calculation, credits, integrations, ancillary obligations and reports.

For this reason, the sooner a company assesses its SAP environment, the greater its ability to plan adjustments, reduce risks and avoid rework during the transition.

What are IBS and CBS?

CBS, the Contribution on Goods and Services, is related to the replacement of federal consumption taxes.

IBS, the Tax on Goods and Services, is related to the gradual replacement of state and municipal consumption taxes.

In practice, both taxes are part of the new model created by Brazil’s Consumption Tax Reform, which aims to simplify the current structure and change the way companies calculate, record and report taxes in their operations.

Even with testing, transition and adaptation phases, system preparation needs to begin before full mandatory adoption.

Where can IBS and CBS impact SAP?

In companies that use SAP, tax changes are rarely limited to a single module or area.

The introduction of new taxes may require the review of different parts of the operation, such as:

• electronic tax documents;
• SAP tax settings;
• calculation rules;
• customer, vendor, material and service master data;
• purchasing and sales processes;
• tax receiving and billing;
• tax calculations and credits;
• tax and management reports;
• integrations with messaging, tax systems and ancillary obligations;
• testing, validation and governance.

For this reason, treating IBS and CBS only as a tax adjustment can be risky. The impact may involve technology, processes, data and business areas.

Electronic tax documents and obligations in 2026

The year 2026 will be an important stage for testing, adaptation and preparation regarding CBS and IBS.

Official guidance indicates that taxpayers should monitor the applicable rules, technical notes, schedules and ancillary obligations related to electronic tax documents.

This period should be used to validate information, review integrations, adjust processes and prepare the operation for the coming years.

Even when there are flexibility measures or a guidance-oriented approach during the transition, companies should not postpone the analysis. The earlier the SAP environment is assessed, the lower the risk of emergency adjustments.

The risk of incomplete preparation

Incomplete preparation may create relevant impacts in daily operations.

Risks include inconsistencies in electronic tax documents, discrepancies in tax calculations, issues with credits, integration failures, rework for tax and accounting teams and greater dependence on manual corrections.

In addition, inconsistent tax data or outdated settings may compromise reports, validations and business decisions.

In SAP, preparation must consider the full information chain: from master data and operations to document issuance, reporting, tax calculation and integration with external systems.

How to start preparing SAP for IBS and CBS

The first step is to perform a diagnosis of the current environment.

Before making any changes, it is important to map which processes may be impacted, which electronic tax documents are used, which integrations exist, which data need to be reviewed and which tax settings require attention.

Based on this diagnosis, the company can build an adaptation plan with priorities, owners, testing stages, validations and governance.

This approach allows the preparation to be conducted with more security, reducing risks and avoiding isolated decisions.

Is your SAP operation prepared?

IBS and CBS require more than a tax update. They require a prepared SAP operation, integrated processes and consistent data.

For companies that use SAP, Tax Reform should be treated as a systemic preparation journey involving tax, IT, accounting, purchasing, sales, logistics and business teams.
