Caution
Portugal: likely outside the issuing mandate — watch e-reporting / cross-border
VAT registration or trading alone, without a fixed establishment, usually keeps you outside Portugal's issuing obligation — but you may still face e-reporting or need to receive structured e-invoices. Confirm your establishment status.
Out of scope
Not in scope for Portugal
With no establishment and no registration or trade in Portugal, the mandate doesn't apply to you today. Revisit this if you open a branch, warehouse or start supplying into Portugal.
In scope
In scope — issue structured e-invoices in Portugal
As an established business issuing domestic B2B invoices, you must send them as compliant structured e-invoices. The mandate applies from 1 January 2027. Set up your platform/format and test before you rely on it.
In scope to receive in Portugal
Even if you don't issue domestic B2B invoices, an established business must be able to receive structured e-invoices. The mandate applies from 1 January 2027. Confirm your receiving capability first.
