General information
What this means for taxpayers
Businesses now have two extra months to stop using NFC-e in B2B sales.
Until January 4, 2026, companies may still issue NFC-e for corporate buyers.
From January 5, 2026, all B2B transactions must be documented via NF-e (model 55) nationwide.
Why the change?
- NFC-e (model 65) = B2C, in-person sales to final consumers (CPF), simplified retail document
- NF-e (model 55) = B2B, commercial flows between companies subject to ICMS
The reform enforces a clear separation between B2C and B2B invoicing, supporting standardization and stronger tax control under SPED digital bookkeeping.
System and compliance impacts (Analysis)
Businesses, retailers, and e-commerce operators must:
- Update ERPs and POS systems to ensure NF-e issuance for all CNPJ customers
- Configure proper B2B fields (CFOP, nature of transaction, ICMS details)
- Align processes and team training before deadline
Failure to adopt NF-e model 55 may result in:
- Invoice rejection
- ICMS compliance issues
- Administrative penalties
State coordination & monitoring
While the rule is national, companies should verify state-specific procedures with SEFAZ authorities, as local implementations may vary.
