In response to upcoming tax reform measures, the Brazilian government is implementing changes to the layouts of electronic invoices (e-invoices).
In March 2025, the National Council of Finance Policy (ENCAT) released an updated version of Technical Note 2025.002. This revision introduces new fields and validation rules to accommodate the future implementation of the new Tax on Goods and Services (Imposto sobre Bens e Serviços – IBS) and the Social Contribution on Goods and Services (Contribuição Social sobre Bens e Serviços – CBS).
As a result, the layouts for both business-to-business (B2B) and business-to-consumer (B2C) e-invoices — specifically NF-e Model 55 and NFC-e Model 65 — will be modified.
The government also published an updated implementation timeline, as follows:
Implementation Timeline
- July 1 to September 30, 2025: Changes available in testing environment
- October 1 to December 31, 2025: Deployment to production environment
- Starting January 1, 2026: New fields and validation rules become fully effective
The changes introduced by Technical Note 2025.002 will be available in the testing environment of the e-invoice portal. This anticipates the previous rollout date of September 1, 2025, and extends the testing period for taxpayers.
During the October to December 2025 period, the changes will be deployed to the production environment, and the use of the new layouts will become mandatory. However, taxpayers will not be required to complete the new fields related to IBS and CBS during this period, as those taxes will only take effect in 2026.
