The Consumption Tax Reform (LC 214/25) will come into effect in January 2026 and requires a high level of preparation from companies.
There will be new codes (CBS, IBS, cClassTrib, Grupo UB), new fields in electronic documents (NF-e, NFS-e, CT-e, NFCom), and the requirement for consistent parameter settings in the ERP system.
In the case of Oracle NetSuite, this preparation needs to start now. Active has compiled 7 practical tips to ensure your operation doesn't risk halting billing in the first month of the transition.
Data cleansing
Review customers, suppliers, items, and HS codes.
Update CST-IBS/CBS and cClassTrib. Without consistent master data, no tax rule or parameterization will function correctly. Companies that begin this review as early as 2025 will have greater security in testing and will be ready for full compliance in 2026.
Tax rules
Clearly define the credit vs. debit schedule and the legal basis for each transaction.
In NetSuite, this means translating legislation into rules for entry, exit, returns, export, and other operations. Without alignment between Tax, Accounting, and IT, the risk of errors and penalties skyrockets.
CBS/IBS/IS Parameterization
Adjust the ERP system to reflect all of the company's operations:
- Inflow: purchases, services, imports.
- Outputs: sales, exports, interstate.
- Calculations: credit/debit formulas, exemptions, zero tax rate.
- Reports: SPED, EFD and management overviews.
This is the heart of the NetSuite Reform.
Integration with tax partners and messaging.
Checking that the tax connectors are prepared is crucial.
The messaging system needs to support new fields (UB Group), high-volume validation, and real-time integration with the ERP. If the connector is not up-to-date, the invoice will be rejected in seconds and the operation may freeze.
Reports and obligations
Review your tax and accounting reports.
Adherence and consistency are tax requirements. Adjust your SPEDs, EFDs, and management reports to reflect the impact of the reform. Without these adjustments, compliance cannot be demonstrated.
Emission tests
Don't wait until January 2026 to test it.
Validate the issuance of NF-e, NFS-e, CT-e, and NFCom in a test environment, simulating rejections and high volume. The rule is simple: without prior testing, there is no guaranteed revenue.
Team training
Empower the Tax, Accounting, and IT teams.
The reform will be dynamic between 2026 and 2033, with constant patches and legal adjustments. Human error can lead to immediate denials. Continuous training ensures that everyone understands the impacts, parameters, and integrations.
Start now
The 2026 Tax Reform is not just a swap of fields; it's a structural change that demands clean data entry, clear rules, solid parameter settings, stable integrations, consistent reports, extensive testing, and well-trained teams.
