Brazil’s new tax reform—introducing IBS, CBS, and IS—requires major updates to electronic tax documents, and Technical Note 2025.002 revises invoice XML layouts to support these new taxes. Although validation rules blocking missing IBS/CBS fields have been postponed, companies are still legally required to include this information from January 1, 2026, making system adaptation essential during the transition period

Following the approval of Constitutional Amendment 132/2023, Brazil began preparing major changes to its tax system. As part of this process, several technical updates are being made to electronic tax documents such as the digital fiscal receipt (NFC-e) and the d-Invoice (NF-e), to support the new consumption taxes.
In 2025, Complementary Law 214/2025 formally created the new taxes:
- IBS (Tax on Goods and Services),
- CBS (Contribution on Goods and Services),
- IS (Selective Tax),
- It also set up the IBS Management Committee.
The law requires states, municipalities, and the Federal District to update their invoice authorization systems so taxpayers can report data related to these new taxes using a standardized XML layout.
To support this reform, the tax authorities issued Technical Note (NT) 2025.002, which updates the layouts of electronic invoices. It introduces new fields, groups, and validation rules so companies can declare IBS, CBS, and IS.
On December 1, version 1.33 of this Technical Note was published with an important change:
the validation rule that would block invoices if the new IBS/CBS fields were empty has been postponed and marked as “future implementation”.
What does this mean in practice:
- From January 2026, e-Invoices (NF-e) and digital fiscal receipts (NFC-e) will NOT be rejected if the IBS and CBS fields are missing.
- However, this is only a technical relaxation, not a legal exemption.
- The law still requires companies under the Normal Tax Regime to include IBS and CBS data in electronic invoices from January 1, 2026.
- If this information is missing, companies may face penalties later, even if the invoice is technically authorized.
In short:
Invoices won’t be blocked, but the legal obligation remains.
Which documents are affected?
The requirement applies to several electronic tax documents, including:
- Digital fiscal receipts (NFC-e) and e-Invoices (NF-e)
- Electronic transport document (CT-e)
- Electronic passenger tickets (BP-e)
- Electronic communication services invoice (NFCom)
- Electronic service invoice (NFS-e)
NT 2025.002 is a large and complex update. To avoid problems during the first year of the new tax system, the tax authorities are:
- Gradually introducing validations,
- Correcting earlier inconsistencies,
- Temporarily relaxing some rules to prevent system overload and rejections.
Evolution of the Technical Note
- Version 1.10: first changes for the new tax model
- Version 1.20: added IBS value fields and naming updates
- Version 1.30: added more fields, validations, and event changes
- Versions 1.31–1.32: fixed incorrect validation rules
- Version 1.33: softened mandatory validations for IBS/CBS fields
- Version 1.34: reinforced this flexibility, especially for the first year of the reform
From January 1, 2026, invoices that include IBS and CBS will have full legal value, even if some validations are still relaxed. Over time, full validation will be enforced as systems stabilize.
Companies and software developers should use this transition period to adapt systems, update XML layouts, and prepare for stricter controls, ensuring compliance before validations become fully mandatory.
