• Simplified DANFE rules expanded: The adjustment introduces and clarifies situations in which a Simplified DANFE (including label format) may be used, particularly for sales outside the establishment and contingency scenarios. [confaz.faz…nda.gov.br]
• Longer timeframe for recipient manifestation: The deadline for key NF‑e recipient events (confirmation, denial, or non‑recognition of transactions) has been extended to 90 days, after which the operation is deemed confirmed if no event is recorded. [confaz.faz…nda.gov.br]

1. Legislative background

On 6 April 2026, the National Council for Fiscal Policy (CONFAZ) and the Special Secretariat of the Brazilian Federal Revenue adopted Adjuste SINIEF No. 14/2026, published in the Official Gazette on 9 April 2026. The measure amends Adjuste SINIEF No. 7/2005, the cornerstone regulation governing Brazil’s electronic invoicing (NF‑e) system and the Documento Auxiliar da Nota Fiscal Eletrônica (DANFE). [confaz.faz…nda.gov.br]

The amendment aims to modernise operational rules, align documentation with practical business needs, and provide greater legal certainty around invoice lifecycle events. [confaz.faz…nda.gov.br]

2. Changes to DANFE and simplified formats

A central element of Adjuste SINIEF No. 14/2026 is the expanded use of Simplified DANFE formats. The regulation clarifies that:

• in the case of sales conducted outside the establishment, the DANFE may be printed on paper smaller than A4 (excluding newsprint), in which case it is referred to as“DANFE Simplificado”, subject to technical definitions in the Manual de Orientação do Contribuinte (MOC);
• a“DANFE Simplificado – Label” format is expressly recognised for certain situations, again subject to defined exceptions and MOC specifications; and
• where contingency rules apply, a second printed copy of a simplified DANFE may be required until the NF‑e is successfully transmitted and authorised. [confaz.faz…nda.gov.br]

These updates reflect the increasing use of mobile sales, logistics‑driven invoicing, and compact printing models in Brazil’s digital tax environment.

3. Extension of recipient manifestation deadlines

The adjustment also revises the rules on recipient manifestation events associated with an NF‑e. Specifically, the events:

• Confirmation of the Operation,
• Acknowledgement of an Unknown Operation, and
• Operation Not Performed,

may now be registered within 90 days from the date of NF‑e authorisation, replacing the earlier, shorter timeframe. [confaz.faz…nda.gov.br]

Crucially, if no manifestation event is recorded within 90 days, the transaction described in the NF‑e is automatically deemed confirmed, producing the same legal effects as an explicit confirmation by the recipient. [confaz.faz…nda.gov.br]

4. Entry into force and effective dates

Adjuste SINIEF No. 14/2026 entered into force on the date of its publication. However, the effects are phased:

• changes related to the recipient manifestation deadline apply from the first day of the second month following publication; and
• all other provisions apply from 3 August 2026. [confaz.faz…nda.gov.br]

This staggered approach gives businesses and system providers limited but defined time to adjust operational and technical processes.

5. Practical implications for businesses

For companies operating in Brazil, the adjustment has several compliance and systems implications:

• invoicing solutions and printing setups must support Simplified DANFE variants in accordance with the MOC;
• internal controls for NF‑e recipient manifestation must take into account the extended deadline and the automatic confirmation effect; and
• ERP and compliance monitoring systems should be updated ahead of August 2026 to ensure alignment with the new rules. [confaz.faz…nda.gov.br]

Overall, Adjuste SINIEF No. 14/2026 reinforces Brazil’s highly structured e‑invoicing model while introducing pragmatic flexibility for modern commercial operations.
