AADE is calling on 7 million owners to check and, if necessary, correct the picture of their property situation.
As they say from the tax administration, we are entering a new digital age for real estate. The new Real Estate Ownership Register of AADE is not just a record, it is the digital footprint of property in Greece, a key tool for rationalising taxation, tackling undeclared property and formulating an effective housing policy.
For the first time, the state will gain a single, complete and reliable picture of the real estate situation in Greece.
Extensive crossovers have already begun between the declarations in E9 and the cadastral data, based on the KEEK (Code Number of the National Cadastre). Upon completion of the processing, owners will receive notifications in order to review the information declared and, where necessary, update or supplement it.
Everything related to the property will be included in the new Register. The type (house or plot), location, surface, use, electrification, rental, residential or unusable, will all be accurately captured. In addition, it will incorporate critical elements to make the necessary intersections.
After the end of the processing of the data, a message will be sent to the property owners to proceed to check the declared data and, in some cases, to fill in information that does not exist either in the VAT or in the cadastre.
It is noted that the file for each property will include all the information about the taxpayer's properties from their basic characteristics, such as type of property, surface, location, floor, electrified, unfinished, if vacant, leased or free of charge, the Property ID Number ATAK (ATAK), the Code Number of the National Cadastre (EIA), data from the National Land Registry, insurance contracts to any pending lawsuits and town planning permits from the Technical Commission of Greece.
In cases where properties are found that have never been declared, for example, to the tax office but only to the cadastre, audits will be initiated by the AADE.
This is because since it has not been declared in E9, no ENFIA or previous taxes have ever been paid on immovable property (VAPP, ETTAK, YETI).
The fines will be more severe, according to the tax administration. On the other hand, there will be no fines for small disputes. As indicated by AADE, the intersection of the data with the cadastre will lead to clarification of the situation for each property.
