Brazil’s consumption tax reform begins in 2026 and introduces mandatory changes to electronic invoice layouts (NFC-e and NF-e), adding new fields and validation rules for the new taxes (IBS, CBS, and IS), with failure to adapt potentially leading to invoice rejections or blocked operations. While the 2026 tax rates are for testing only and have no financial impact, most taxpayers must update their systems from 1 January 2026, except for Simples Nacional and MEI taxpayers, who will be affected starting in 2027.

Brazil’s consumption tax reform will start in 2026 and will be gradually implemented until 2033. As part of this reform, changes to the layout of electronic fiscal documents, including the digital fiscal receipt (NFC-e) and the e-Invoice (NF-e), will become mandatory in 2026 and will directly affect how companies issue invoices.
From 1 January 2026, all electronic fiscal documents must use a new invoice layout. This layout adds new fields and data groups related to the new taxes:
- IBS (Goods and Services Tax)
- CBS (Goods and Services Contribution)
- IS (Selective Tax)
New validation rules and system events are also being introduced, in line with recent constitutional and complementary tax laws.
Companies that do not update their systems and processes may face serious operational issues. Invoices may be rejected, issuance and receipt of fiscal documents may be blocked, or additional corrective documents may be required if the new fields are missing or incorrectly completed.
Although the new taxes appear in the invoice layout, the rates shown in 2026 (0.9% CBS and 0.1% IBS) are for testing purposes only. They will not generate any tax payments or financial impact during 2026.
An important exception applies to companies under the Simples Nacional regime (a special simplified tax regime designed for micro and small businesses). In 2026, fiscal documents issued by:
- Simples Nacional taxpayers,
- Simples Nacional taxpayers exceeding the sublimit,
- MEI taxpayers (Individual Microenterpreneurs),
will not be affected by these changes. These taxpayers will only be impacted starting in 2027.
Companies are strongly advised to adjust their systems and internal processes in advance to ensure business continuity and compliance during the transition period.
