Brazil is updating its electronic fiscal document system as part of the country’s VAT reform.
From August 3, 2026, businesses under the regular tax regime will generally be required to complete the new CBS and IBS fields when issuing electronic fiscal documents. Documents may be rejected if the required information is missing.
Businesses should therefore update their:
- invoice and XML layouts,
- ERP and tax calculation systems,
- validation rules,
- reporting processes, and
- connections with Tax Authority platforms.
Brazil uses different electronic documents depending on the type of transaction:
- e-Invoice (NF-e): sales of goods,
- e-Receipt (NFC-e): retail sales to final consumers,
- Electronic Service Invoice (NFS-e): supplies of services
- Electronic Transport Document (CT-e): freight and transport services,
- Electronic Manifest of Fiscal Documents (MDF-e): transport and logistics movements,
- Electronic Electricity Invoice (NF3e): electricity and utility supplies,
- Electronic Communication Services Invoice (NFCom): communication and telecommunications services, and
- Electronic Passenger Ticket (BP-e): passenger transport services.
Each document has its own XML structure, validation rules and issuance procedures.
Brazil’s tax reform introduces two new VAT-style taxes:
- CBS, administered at federal level; and
- IBS, administered at state and municipal level.
During the transition period, businesses will need to support both the existing taxes and the new CBS and IBS requirements.
The layouts of the electronic fiscal documents are being updated to include CBS and IBS information. Some documents may also need to include information relating to the Selective Tax.
For example, the e-Invoice (NF-e) and e-Receipt (NFC-e) technical documentation introduces new fields and validation rules for the tax reform. The national NFS-e layout has also been updated with dedicated IBS and CBS groups.
Businesses should review the technical notes applicable to each document they issue and ensure that their systems are ready for the new validation requirements.
