E-invoicing in Portugal for Public Procurement (2023 Updates)

Last modified on 2023-08-09 in Countries

E-invoicing in Portugal has been phased in for public procurement or B2G transactions since 2021 to align with the e-invoicing Directive 55/2014/EU and VAT in the Digital Age (ViDA) proposal. Portuguese digital reporting is enforced through a software fiscalization system along with mandatory SAF-T reporting since 1 January 2023.

Latest news

SMEs and microenterprises received an extension of the deadline for issuing e-invoices to the public sector. The new deadline for this regulation is 1 January 2024.

Implementation timeline

• 1 January 2024: Digital signatures are required for e-invoices and micro and SMEs must issue e-invoices for B2G transactions.

Fiscalization and SAF-T

Portugal utilizes a software fiscalization system that primarily revolves around the use of POS applications certified by the Direcção Geral dos Impostos (DGCI), or the Portuguese Tax Authority. The system must also undergo formal check-ups to maintain its reliability. This requires a local contact in order to certify and re-certify a POS system.

From 1 January 2023, it will also be obligatory for local organizations and non-resident taxpayers to submit their monthly standard audit files for tax (SAF-T) by the 5th of every month.

How to send a Portuguese B2G e-invoice

Here are the steps to send a compliant e-invoice:

1. Make sure that the e-invoice is in a proper format, such as UBL 2.1 “CIUS-PT”, CEFACT “CIUS-PT” or other European standard EN 16931 compliant formats.

2. Establish a connection with an e-invoicing service provider such as DDD Invoices in order to comply with requirements.

3. Connect to the FE-AP portal

4. Transfer the e-invoice via the e-invoicing service provider

ATCUD code

This is a series number (ATCUD) assigned to an invoice that can be used for identification as well as confirmation of validity since 1 January 2023. The ATCUD consists of the following format; ATCUD: validation code-sequential number. The validation code is received on request from the eSPap.

QR code

The QR code has been required since 2022, but may be left out for those issuers who use electronic data interchange (EDI) for standardized intercompany communication of invoices. The advantage of QR codes is that they are easier to read by IT systems and can hold more information than barcodes. The first part of the code consists of a tax authority-provided validation code, while the second part consists of the sequential document number.
