Applies to

B2B, B2G

October 1, 2026

Does this apply to me?

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

Is your business established in Greece (registered office, branch or fixed establishment)?

Do you issue domestic B2B invoices in Greece?

Greece: likely outside the issuing mandate — watch e-reporting / cross-border

VAT registration or trading alone, without a fixed establishment, usually keeps you outside Greece's issuing obligation — but you may still face e-reporting or need to receive structured e-invoices. Confirm your establishment status.

Not in scope for Greece

With no establishment and no registration or trade in Greece, the mandate doesn't apply to you today. Revisit this if you open a branch, warehouse or start supplying into Greece.

In scope — issue structured e-invoices in Greece

As an established business issuing domestic B2B invoices, you must send them as compliant structured e-invoices. The mandate is already in force (since October 2026). Set up your platform/format and test before you rely on it.

In scope to receive in Greece

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 October 2026). Confirm your receiving capability first.
