AADE simplifies property transfers with automatic KAEK entry in E9 forms

Under Decisions A.1201/2026 and A.1203/2026, issued by AADE Governor Giorgos Pitsilis, the KAEK will be transferred from declarations submitted through the myPROPERTY digital platform to the E9 Declaration of Property Details, eliminating the need for taxpayers to enter the code again manually.

The measure applies to property sales and purchases, donations and parental gifts covered by the system for the automatic generation of E9 declarations. It is intended to reduce repetitive data entry and minimise the risk of discrepancies between tax records.

How the Process Works

For transactions that meet the applicable requirements, the submission of the property transfer deed through the myPROPERTY platform triggers the automatic generation of the corresponding E9 declarations.

Property details are retrieved from the available information in the Property Register and from declarations submitted as part of the transfer process. Under the new functionality, the KAEK is added to the fields completed automatically. The code serves as the unique identifier for each property in the National Cadastre.

The automation itself is not entirely new. The automatic generation of E9 declarations for certain property transfers has been in place since 2023 and was subsequently extended to cover donations and parental gifts. The addition of the KAEK expands the range of information transferred between the tax administration’s digital systems.

What Changes and What Remains Outstanding

Despite the simplification, the new measure does not mean that the E9 system has been fully integrated with the National Cadastre. It involves the automated transfer of a specific data field from myPROPERTY to the Property Register, rather than a comprehensive exchange of information between the two databases.

This distinction has practical implications. Any discrepancies between property titles, cadastral records and E9 declarations will not be automatically corrected under the new procedure. Similarly, the automatic completion of the KAEK does not relieve property owners of their responsibility to verify the accuracy of their property records.

For the property market, however, the development removes another administrative step from the transfer process and improves the consistency of information recorded in the tax administration’s digital systems.

The next priority remains achieving substantive interoperability between the National Cadastre and the tax administration’s Property Register, allowing property data to be systematically cross-checked and used without requiring owners to submit repetitive declarations.

For now, AADE is introducing a targeted simplification that reduces bureaucracy while preserving the need for property owners to check and update their asset records where necessary.
