Greece to launch new property registry “MIDA” to centralize real estate ownership data
Greece is set to activate a new digital property registry, the “Real Estate Ownership and Management Register” (MIDA), within days, in a reform that aims to fundamentally reshape how real estate assets are recorded, verified, and taxed.
The new system, introduced by the Ministry of National Economy and Finance and recently passed in Parliament, will function as a centralized digital file for every property in the country. It will be directly linked to tax declaration forms (E9), creating a unified database that connects ownership details with declared property use.
Under the new framework, property usage declarations will not be accepted unless the property has first been registered in the E9 system. Authorities say the reform is designed to reduce errors, omissions, and inconsistencies across tax and property records, strengthening the capacity of the Independent Authority for Public Revenue (AADE) to cross-check data.
From 2027 onwards, the property tax (ENFIA) will be calculated based on actual building surface areas as verified through the Electronic Building Identity system. However, the government has clarified that no retroactive penalties will be imposed for discrepancies between past E9 declarations and verified measurements.
The reform introduces a differentiated approach to taxation based on real surface area:
If a property is found to be smaller than previously declared, owners will benefit from lower future tax obligations, including ENFIA and transfer taxes. Conversely, if a property is larger than declared, higher taxes will apply from 2027 onwards, but without retroactive charges for previous years.
The legislation also stipulates that existing ENFIA assessments and issued certificates will not be considered inaccurate solely due to discrepancies where the actual building size is smaller than that recorded in land registry files, ownership titles, or building permits.
Authorities describe MIDA as a key step toward digitalizing and consolidating Greece’s fragmented property records, aiming to improve transparency in real estate taxation and strengthen public revenue oversight.
Greece is set to launch the MIDA property registry, linking real estate ownership with tax records and shifting ENFIA calculations to actual building measurements from 2027.
