The noose is tightening around income declared from rental properties, as the RMA activates the new Register of Property Ownership and Management, a tool that comes to “unlock” tax returns. The aim is to identify amounts that are not declared or recorded incorrectly, as well as to automate the pre-filling of returns.

The process is simple: the owners will declare the leases on the platform and the AADE will automatically pull the data for the E1 and E2. The returns will arrive almost ready to the taxpayer, with the taxpayer being asked to check and confirm or correct any inaccuracies. At the same time, renters will also have access, who will be able to see what the landlord declares for the property they are renting.

The register will go live in the near future and will include data for each property from E9, the Land Registry, DEDN, leases, as well as planning information, insurance policies and pending lawsuits. All data will be linked to the Property Identification Number (ATAK) and the Registry Code (RIC).

At the first stage, each owner will have to declare the use of the property – whether it is owner-occupied, leasehold or vacant. The interconnection of the People’s Property Register with the Territory Register will allow undeclared or under-declared properties to be identified, while rental income will be automatically cross-checked with tax returns.

The platform will be updated with each new or expired lease and will pre-populate both the landlord’s income and the tenant’s related expenses. If a discrepancy is detected – for example, a different amount of rent than what is actually paid – the tenant will be able to terminate it. The new mechanism brings full insight into the property of more than 7 million taxpayers.

This is the first step in a digital “clean-up” in the property market, aimed at eliminating “grey” returns and improving tax compliance. As the data is gathered and cross-referenced, less will be left to chance – and that, simply put, means that pre-filled returns are here to stay.

Unified Property Registry from 2026

Meanwhile, the Unified Property Registry, a new platform, is also moving forward and is expected to be fully operational in early 2026. It will interoperate with all of the state’s digital platforms, bringing together in a single point a complete profile for each property.

Automatically notifying the relevant authorities of any change in a property’s ownership or characteristics will eliminate citizen hassles and time-consuming procedures. At the same time, the platform will allow for fast transactions and enhance transparency and control, enabling audit bodies to identify cases of undeclared square meters.

The Unified Real Estate Registry is based on interoperability between the databases of various state agencies, with the National Cadastral Code Number (NCRN) as the central identifier.

With the completion of this project, every owner will be able, with a simple consent via gov.gr, to digitally grant access to his/her property data, eliminating bureaucracy and ensuring legal security in transactions.
