Learn how to comply with tax requirements as a retailer in Portugal

If you are a retailer in Portugal, tax compliance is essential. But did you know that your retail management software must also comply with the country’s tax requirements? Each state has its own regulations, and making sure you are compliant will help you avoid complications with the national tax authorities.

In Portugal, there are various tax requirements that you should be aware of.

1. Document Identification

Starting in 2022, invoices and tax documents must include a two-dimensional barcode known as a QR code.

2. ATCUD Unique Identification Code

On January 1, 2023, it became mandatory to include the  unique ATCUD (Code Validation Numero Sequential) identifying code on all fiscally relevant documents, including invoices.

3. Digital signature on e-invoices

New as of January 1, 2024, electronic and PDF invoices will need to have a digital signature in order to be valid.

It is essential that the software you use to perform all these tasks is approved by the Portuguese Tax and Customs Authority (Autoridade Tributária e Aduaniera de Portugal)
