The Brazilian Federal Revenue Service published Regulatory Resolution CGSN nº 191/2026 on 14 August 2026, establishing that the issuance of the National Electronic Invoice (Nota Fiscal de Serviços Eletrônica – NFS‑e Nacional) will become compulsory for all microenterprises (ME) and small businesses (EPP) opting into the Simples Nacional regime, effective 1 November 2026. This requirement replaces the prior patchwork of state‑level electronic invoicing systems and introduces a unified, federally governed platform for documenting service operations. The resolution also clarified that, while the NFS‑e Nacional obligation begins in November 2026, the substantive application of the CBS and IBS taxes under the Consumption Tax Reform (RTC) to Simples Nacional participants will commence only on 1 January 2027, providing a two‑month transitional window for system adaptation. The RFB emphasized that the mandate aims to enhance fiscal transparency, curb invoice fraud, and streamline cross‑border service taxation within the forthcoming dual‑VAT framework.
Key Takeaways
- Unified invoicing platform: Starting 1 Nov 2026, ME and EPP entities must generate all service invoices through the NFS‑e Nacional portal, eliminating the need for multiple state‑specific certificates and reducing integration costs for accounting software.
- Transitional relief: Although the NFS‑e Nacional is mandatory from November, the CBS/IBS tax liability for Simples Nacional taxpayers does not arise until January 2027, allowing businesses to test the invoicing system without immediate tax impact.
- Anti‑fraud measures: The centralized NFS‑e Nacional includes real‑time validation against the RFB’s taxpayer registry, automatic detection of duplicate or forged invoices, and mandatory digital signatures, significantly raising the difficulty of issuing fraudulent documentation.
