Brazil Updates e-Invoice Requirements for New Taxes Under 2026 Tax Reform Transition

• Brazil’s tax reform introduces new taxes (IBS, CBS, IS) requiring updates to electronic tax documents.
• Technical Note 2025.002 revises invoice XML layouts to include new fields and validation rules for these taxes.
• The rule blocking invoices missing IBS/CBS fields is postponed, but companies must still include this data from January 1, 2026, or risk penalties.
• The changes affect multiple electronic tax documents, including NFC-e, NF-e, CT-e, BP-e, NFCom, and NFS-e.
• Tax authorities are phasing in validations and temporarily relaxing some rules to ease the transition.
