Invoices with QR codes no longer arrive in January! Only in 2022

However, in an order issued by the Secretary of State for Tax Affairs, António Mendonça Mendes, it is said that QR codes will only become mandatory starting January 1, 2022.

Invoices with QR codes no longer arrive in January 2021. In a document signed on Friday, it is determined that "the mention of the unique document code (ATCUD) on all invoices and other fiscally relevant documents […] be mandatory only from 1 January 2022 ".
The transitional period that began on 1 December has also been postponed to the beginning of the second half of 2021.
