Greece's tax authority now fills in the Cadastre code in the E9 after a sale, gift or parental transfer

Since 7 October 2026, when a property in Greece is sold, gifted or passed to a child as a parental transfer (γονική παροχή, goniki parochi), the tax authority copies the property's Cadastre code into the owners' E9 property declaration itself.¹²⁶ This happens when the deal goes through myPROPERTY, the online application of ΑΑΔΕ (Ανεξάρτητη Αρχή Δημοσίων Εσόδων, Anexartiti Archi Dimosion Esodon, the Independent Authority for Public Revenue), Greece's tax authority, where the transfer-tax declaration, or the gift or parental-transfer tax declaration, is filed.¹²³

What changed on 7 October 2026?

ΑΑΔΕ's Governor, Georgios Pitsilis, signed two decisions in Athens on 1 October 2026: Α.1201/2026 for sales and Α.1203/2026 for gifts and parental transfers.¹² Both were published in the Government Gazette (ΦΕΚ) Β 6051 on 7 October 2026 and apply from that date.¹²⁶

The E9 (Δήλωση Στοιχείων Ακινήτων, Dilosi Stoicheion Akiniton) is the declaration of the property a taxpayer owns, kept in ΑΑΔΕ's property register, the Περιουσιολόγιο (Periousiologio).³⁷ The ΚΑΕΚ (Κωδικός Αριθμός Εθνικού Κτηματολογίου, Kodikos Arithmos Ethnikou Ktimatologiou) is the property's number in the Hellenic Cadastre, the national land register known as the Κτηματολόγιο (Ktimatologio).¹¹⁵

Under both decisions, for every party to the contract, the E9 field "Κ.Α.Ε.Κ./Κωδ. ακινήτου" is filled with the ΚΑΕΚ taken from the tax declaration already filed in myPROPERTY.¹² ΑΑΔΕ says the change reduces repeated entries and helps improve the quality and consistency of the data in the Περιουσιολόγιο.³⁴⁵

From 7 October 2026, the Cadastre code in the E9 is copied from the myPROPERTY declaration for every party to a sale, gift or parental transfer.¹²

How does the automatic E9 work?

The ΚΑΕΚ rule adds to a system that already existed: automatic E9 after property sales began as a pilot on 7 July 2023.⁷²⁰ Decision Α.1015/2024, published on 31 January 2024, extended it to gifts and parental transfers.⁸ A decision of August 2024 extended it to gifts of a share of a property and to gifts to more than one recipient.¹⁰¹¹

The automatic E9 is created when the notary posts the deed in myPROPERTY.⁷⁹ The parties receive a notice in their myAADE inbox, followed by an email.⁷⁹¹² The automatic E9 counts as finally filed on the day the deed is posted.⁷⁸

What does the owner still have to do?

For the E9 to be created automatically, the seller must first update the property's details in their current property record in the Περιουσιολόγιο, before the deed is posted in myPROPERTY.⁷⁹ The buyer must do the same if they already hold a right in the property.⁷⁹ Our advice is to check the automatic E9 against the contract once the deed is posted. If the automatic E9 does not match the contract, the owner can file an amending E9 (τροποποιητική δήλωση, tropopoiitiki dilosi) within the legal deadline.⁷⁹¹²

When is there no automatic E9?

There is no automatic E9 if the deed's details are not entered, or the deed is not posted in myPROPERTY, by (and including) 10 January of the year after the contract was signed.⁷¹³ For a contract signed in 2026, that cut-off is 10 January 2027, by our calculation.⁷¹³ By our calculation, 10 January 2027 is a Sunday; the decision text says «έως και» ("up to and including", in our translation) 10 January and does not move the date to a working day.⁷¹³ Until decision Α.1193/2024, published on 30 December 2024, the cut-off was the last working day of February of the following year.¹²¹³

There is also no automatic E9 if the property's ΑΤΑΚ, the tax register's own number for the property, was not entered in the declaration.⁷⁸ For gifts and parental transfers, there is a further exception where the share of full ownership, bare ownership (ψιλή κυριότητα, psili kyriotita, ownership without the right to use the property) or usufruct (επικαρπία, epikarpia, the right to use the property and take its income) that the donor or parent, or the recipient or child, already holds in the property is below 100%.⁸¹⁰ In all these cases the owner files the E9 themselves within the legal deadline.⁷⁸

Does this cover inheritance?

The two decisions refer only to transfer-tax declarations and to gift or parental-transfer-tax declarations.¹² Neither decision, nor ΑΑΔΕ's press release of 8 October 2026, mentions inheritance.¹²³ In our reading of the decisions, heirs should not assume the ΚΑΕΚ will be filled in for them under these rules.¹²

A separate tool for correcting boundaries

The Cadastre opened a different service on Friday 18 September 2026: metavoles.ktimatologio.gr, for correcting a property's geometric data, such as its boundaries, online.¹⁴¹⁵ Its legal basis is decision 440/9/26-08-2026 of the Cadastre's board, published in ΦΕΚ Β 5454 on 8 September 2026 under law 5142/2024.¹⁴¹⁶

Owners, or people they authorise, log in with their Taxisnet credentials and apply.¹⁴¹⁵ An engineer the owner hires can also apply on the owner's behalf.¹⁴ For now, until notification is automated, the applicant arranges for the application to be served by a court bailiff.¹⁴¹⁵ From the same date the old correction procedures were abolished, with a transitional exception where the Greek state or a general-government body holds a right in the property or is affected by the correction.¹⁴¹⁵

A wider project to link property databases, the Ενιαίος Κόμβος Ακινήτων (Eniaios Komvos Akiniton, Single Property Hub), was still at tender stage on 29 September 2026, with proposals due by 30 November 2026.¹⁷¹⁸¹⁹
