Brazil's Tax Reform Causes Modifications in Electronic Tax Documents

The ongoing Tax Reform in Brazil has caused significant changes to the national Electronic Service Invoice system (NFS-e) to accommodate the newly introduced consumption taxes.

On July 31, 2024, the NFS-e Management Committee issued the DFe Technical Note 2024.001 IBS/CBS version 1.00.

What does it mean? The note provides important changes to the format and structure of electronic tax documents, including new taxes (CBS, IBS, and IS) created by a recent constitutional amendment. These changes ensure that the documents are updated to reflect and comply with the new tax laws

Introduction of new information groups

The technical note presents new information groups and fields tailored to handle the newly implemented taxes. These changes are part of an initiative to align electronic tax documents with the updated tax system mandated by the reform. Several types of electronic invoices will be impacted, including those related to transportation and communication services.

Key Updates Include:

  • New Information Groups: Optional fields have been added to capture details on IBS/CBS taxation, including tax rates, calculation bases, and specific tax codes.
  • Totalization Groups: Additional fields have been introduced to summarize the total amounts for IBS and CBS, providing greater clarity in tax reporting.

These updates are crucial for meeting Brazil's new tax requirements. Businesses must familiarize themselves with these changes to comply with the latest reporting obligations.

Implementation Schedule:

  • Approval Environment (company testing): September 1, 2025
  • Production Environment: October 31, 2025
  • Operational Deadline: The new groups and fields must be fully operational by January 1, 2026.
