Electronic Tax Declaration through SAF-T in Portugal

Portugal uses different SAF-T files for electronic VAT return, electronic accounting and transport documents.

Submit your tax, accounting, and transport information through the SAF-T PT system in Portugal

The SAF-T (Standard Audit File for Tax) system was introduced in Portugal in 2008 to facilitate the electronic submission of VAT returns, accounting records, and transport documents. This system requires files to be generated in specific formats containing detailed information regarding commercial transactions. Taxpayers with headquarters, based or permanently established in Portugal, subject to corporate tax (IRC) or income tax (IRS) that keep organized accounting, must comply with this system.

There are three files that must be sent electronically to the Portuguese tax authority in its SAF-T PT version:

SAF-T PT facturación

SAF-T PT for invoicing

The file for the electronic VAT return in SAF-T PT format must be submitted before the 5th of each month. The authorities require that the files be sequentially generated and undergo an encryption process that includes the electronic signature of the previous invoice as a control system for the file creation process.

SAF-T PT contabilidad electrónica

SAF-T PT for electronic accounting

Accounting systems must register the information to generate the electronic accounting file in SAF-T PT format. This monthly or annual declaration must include the list of items, customers and suppliers, VAT regimes, accounting movements, and chart of accounts.

Documentos de transporte

Transport documents

VAT taxpayers are required to report transportation documents related to the movement of goods to the tax authority. The EDICOM solution automates the sending of data in real-time to the Portuguese tax authority and automatically receives the code to be integrated into the transport document. This code allows for the movement of goods.

Both SAF-T files must include the following information:
