- Portugal has proposed delaying the mandatory qualified electronic signature (QES) requirement for e-invoices until January 1, 2028.
- Under the draft 2027 State Budget Law, PDF invoices without a QES would remain valid through December 31, 2027.
- The requirement had previously been set to start on January 1, 2027.
- If approved, the extension would give businesses more time to prepare for the technical and operational changes needed for QES e-invoicing.
