ELSTER organisational certificate and eNoVA: a 5‑point pre‑notarisation checklist for foreign buyers — Oct 2026

What changed on 1 October 2026 — and why it matters to you

From 1 October 2026 certain notarial notifications — including the Veräußerungsanzeige required under § 18 GrEStG — must be sent electronically as a structured dataset via the eNoVA module and ELSTER. The Federal Notary Chamber (Bundesnotarkammer) documents eNoVA’s first mandatory obligations and the requirement that the notification is transmitted electronically. ([bnotk.de](https://www.bnotk.de/aufgaben-und-taetigkeiten/rundschreiben/details/elektronischer-notar-verwaltungs-austausch-enova-erste-verpflichtungen-ab-dem-1-oktober-2026?utm_source=openai))

Under the Grunderwerbsteuergesetz the courts, authorities and notaries may withhold the original deed and copies until the Veräußerungsanzeige has been sent in full (see § 18 GrEStG). The electronic dataset must contain the fields listed in § 20 GrEStG and follow the legally determined interface and data specification (see GrEStG implementing regulation / GrEStE‑AV references). Failure to provide a correctly completed electronic notification can therefore delay or block the notarisation process and subsequent issuance of documents the buyer needs.

Five‑point checklist: what you must prepare before the notarisation appointment

1) Register an ELSTER organisational certificate and assign it early. Set up an ELSTER organisational account and obtain an Organisationszertifikat (not a simple personal Mein‑ELSTER login). The certificate must be active and — if used by the notary or your agent — available in the notary’s XNotar/eNoVA settings (the notary software requires the organisational certificate to transmit via ELSTER). ELSTER registration includes a postal activation step; allow time for issuance and for your administrator to install the certificate. Practical guides for organisational registration are published by ELSTER and in regional step‑by‑step PDFs.

2) Provide the exact tax identifiers the dataset requires. The dataset requires tax identifiers as stated in GrEStG: for natural persons the Identifikationsnummer under § 139b AO or, for legal entities, the Wirtschafts‑Identifikationsnummer under § 139c AO (until full rollout some offices still accept the tax number). Put the correct number on record in advance and confirm which identifier the receiving Finanzamt expects. Missing or incorrect IDs are a common reject reason. ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/grestg_1983/BJNR017770982.html?utm_source=openai))

3) Deliver complete, standardised identity and organisational data. Prepare full legal names, current residential or registered addresses, dates of birth, legal form, authorised representatives with their contact details and any representation documents (POA) certified and apostilled if executed abroad. § 20 GrEStG lists mandatory fields the electronic form must contain; the notary must receive all these items before sending. If you are an entity, confirm the exact corporate register entry and tax numbers to avoid mismatches. ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/grestg_1983/__18.html?utm_source=openai))

4) Translate and legalise foreign documents early. If the notary must rely on foreign identity documents, powers of attorney or corporate extracts they must be in the form the notary will accept (certified translation, apostille or legalized consular certification). Deliver certified translations and apostilles well before the appointment so the notary can include them correctly in the structured dataset. Failure here commonly causes the notary to refuse submission until formalities are cured. (Practical note: ask the notary which language/version they will accept.)

5) Confirm the receiving Finanzamt is ready and agree a timeline with the notary. Not all Finanzämter enabled eNoVA/ELSTER reception at the same date; the Bundesnotarkammer and the notary will know which offices are ready. Ask the notary to confirm the target Finanzamt’s acceptance and whether a pre‑check is possible. If an initial transmission is rejected, the notary must correct and resend; that can take days and may block document release under § 18 GrEStG. ([onlinehilfe.bnotk.de](https://onlinehilfe.bnotk.de/einrichtungen/notarnet/xnotar/modul-enova.html?utm_source=openai))

Practical timeline and red flags

Start ELSTER organisational registration at least 2–3 weeks before the notarisation date: postal activation, certificate installation and any administrator steps take time. Confirm translations and apostilles are complete 7–10 days before the appointment. Ask the notary for a pre‑submission check of the dataset where available; this reduces the chance of a rejected transmission. If the Finanzamt rejects the dataset, expect a correction round that can take several working days — during which the notary may lawfully withhold deed copies. When in doubt, delay signing until identifiers (tax IDs, corporate registry entries) are certain.

Note: this article explains procedural steps only. For transaction‑specific tax consequences or when you face a rejected filing that puts funds or property transfer at risk, engage a German tax adviser (Steuerberater) and the acting notary immediately.

Next practical steps (quick checklist for your inbox)

• Ask your notary which Finanzamt will receive the electronic notice and whether they can perform a pre‑check. • Provide your exact tax identifier (IdNr. or W‑IdNr. / Steuernummer as directed) in writing. • Start ELSTER organisational registration today; send proof to the notary. • Send certified translations and apostilles of any foreign POA or corporate extracts. • Agree a contingency plan with the notary for a rejected transmission (schedule, who pays for delays).
