Greece’s 2027 property changes: What buyers and owners need to know
Greek Prime Minister Kyriakos Mitsotakis has announced series of housing measures affecting property buyers and owners at the Thessaloniki International Fair.
In The News
Greece is preparing to introduce a sweeping reform in the way property ownership and usage are recorded. Through the creation of the Μητρώο Ιδιοκτησίας και Διαχείρισης Ακινήτων (ΜΙΔΑ) — translated as the Property Ownership and Management Registry — authorities aim to create a comprehensive digital record of every property in the country.
The project is being developed by the Independent Authority for Public Revenue (Ανεξάρτητη Αρχή Δημοσίων Εσόδων - ΑΑΔΕ), in cooperation with the Ministry of National Economy and Finance. Its goal is to consolidate fragmented real estate information into a single platform and provide a clearer picture of property ownership and use across the country.
The new registry also featured prominently in discussions at the Property Owners’ Conference organised by the Panhellenic Federation of Property Owners (ΠΟΜΙΔΑ). The event brought together representatives of the government, local authorities, the Independent Authority for Public Revenue (ΑΑΔΕ), the Hellenic Cadastre, and property owners from across the country.
During the conference, the new registry was presented as one of the most significant reforms in the Greek real estate sector in recent years. Speaking at the event, Minister of National Economy and Finance, Kyriakos Pierrakakis, described the initiative as “the most systematic recording of the use of private real estate ever carried out in the country.” According to the minister, the registry will give the state a comprehensive digital overview of the country’s property stock and the way the real estate market actually functions.
Bringing scattered records into one system
Until now, property information in Greece has been spread across multiple institutions. Tax records are derived from E9 declarations submitted through Taxisnet and include the unique property identification number used by the tax authority, (Αριθμός Ταυτότητας Ακινήτου - ΑΤΑΚ). At the same time, cadastral information is maintained by the Hellenic Cadastre, where each property is assigned a National Land Registry Code Number (Κωδικός Αριθμός Εθνικού Κτηματολογίου - ΚΑΕΚ).
Additional information is held by other organisations, such as Hellenic Electricity Distribution Network Operator (ΔΕΔΔΗΕ), which manages electricity supply numbers, as well as water and sewerage utilities. Planning permits are recorded through the Technical Chamber of Greece (Τεχνικό Επιμελητήριο Ελλάδας - ΤΕΕ).
The Property Ownership and Management Registry is designed to connect these systems and gather their data into one digital registry. Each property will have an individual electronic file containing its key characteristics and administrative information.
These files are expected to include the property’s type, location, surface area, and floor level, along with information about its status — whether it is electrified, unfinished, vacant, rented, or granted for free use.
Property owners will verify their information
As part of the registry’s rollout, the Independent Authority for Public Revenue will invite property owners to log in to the upcoming platform and review the information recorded about their real estate.
This verification stage is intended to ensure that the data transferred from different systems is accurate. Owners will be able — and in some cases required — to correct inaccuracies or add missing details so that the registry reflects the real characteristics of their properties.
The process effectively amounts to a nationwide update of property records.
Improving tax transparency
One of the main objectives of the Property Ownership and Management Registry is to strengthen tax oversight.
By integrating data from several sources, the Authority for Public Revenue will be able to conduct more effective cross-checks. For example, the authority may detect cases where a property appears to be rented but no rental income has been declared on tax returns. Differences between cadastral records and tax declarations may also be easier to identify.
The registry may also help ensure that the property tax (ENFIA) corresponds more accurately to the characteristics and objective value of each property.
Monitoring agricultural land
The registry is also expected to play a role in verifying agricultural land used in subsidy applications. Once connected with the Cadastre, the upcoming platform will allow authorities to create digital records for agricultural plots that include their geospatial location, size, land category, and leasing arrangements. This will help confirm that farmland declared in subsidy applications actually exists and that any leasing arrangements are legitimate.
Farmers are already required to declare the ΑΤΑΚ for agricultural plots when submitting subsidy applications. In the future, these declarations will be cross-checked with the information stored in the new registry.
A step toward integrated property administration
This step reflects a broader effort to modernise Greece’s public administration through digital infrastructure and interconnected data systems. Once fully implemented, the registry will provide authorities with a unified overview of the country’s real estate landscape, minimizing data fragmentation.
For property owners, it marks the beginning of a new system in which each asset will have a single digital record — one that brings together tax, cadastral, and utility information in a single place.
