Three questions. The fixed-establishment rule is where most foreign businesses get it wrong.

Caution
Poland: likely outside the issuing mandate — watch e-reporting / cross-border
VAT registration or trading alone, without a fixed establishment, usually keeps you outside Poland'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 Poland
With no establishment and no registration or trade in Poland, the mandate doesn't apply to you today. Revisit this if you open a branch, warehouse or start supplying into Poland.
In scope
In scope — issue structured e-invoices in Poland
As an established business issuing domestic B2B invoices, you must send them as compliant structured e-invoices. The mandate is already in force (since April 2026). Set up your platform/format and test before you rely on it.
In scope to receive in Poland
Even if you don't issue domestic B2B invoices, an established business must be able to receive structured e-invoices. The mandate is already in force (since April 2026). Confirm your receiving capability first.
