In response to Lusa, the Ministry of Finance states that the Secretary of State for Fiscal Affairs, Nuno Santos Félix, “decided to extend the period for verifying and communicating invoices by two days”, after constraints and specific access limitations on Monday.

On Monday, AT stated that it received a high level of access, which led to taxpayers having difficulty validating invoices.

On that day, AT admitted that "the reported situations may be associated with this high number of accesses" and that it was monitoring "the aforementioned service and allocating all the necessary resources to optimise the taxpayers' user/access experience", remembering that in addition to the e-invoice website, the e-invoice application is also available.

Validating invoices is one of the necessary steps in preparing the annual IRS declaration.

The delivery of the annual IRS declaration begins on April 1st, lasting until June 30th.
