A new regulatory framework for property owners, landlords, and users enters force with the launch of the Registry of Property Ownership and Management (MIDAS), expected to go live in early July. A ministerial decision issued by the Ministry of National Economy and Finance—incorporated into a broader legislative bill—introduces specific penalties for owners who fail to declare or inaccurately report how their properties are being used. In certain cases, fines may reach as high as €1,000.
Mandatory Declaration of Property Use
The new digital registry will consolidate data on both property ownership and usage, aiming to cross-check information and curb attempts to conceal details. Owners and landlords must declare any rental or gratuitous use of their properties on time, while users bear responsibility for the accuracy of the information they submit.
€500 Fine for Late Declarations
Under the rules, declarations of property use must be submitted within three months of the start of a lease or free-of-charge arrangement. If this deadline passes without submission, an administrative fine of €500 applies. The same penalty applies when required updates to the registry are not made in time in connection with the Unified Application for State Support.
Stricter Penalties for False Information
Particular emphasis is placed on false or misleading declarations. If a tenant or beneficiary submits inaccurate data that is subsequently used to obtain state support, allowances, subsidies, or rent reimbursements, a €1,000 fine is imposed. Where erroneous information has not been leveraged for financial gain or public benefit, the penalty drops to €100.
Linking MIDAS with the E9 Form
The new regulation directly links MIDAS with the E9 tax form—the annual real estate declaration. Before submitting any usage declaration, owners must first ensure that core property details are registered and up to date in the system. This integration aims to unify all available property data within a single digital environment.
ENFIA Reform from 2027: Tax Based on Actual Surface Area
Major changes are also planned for the calculation of the ENFIA property tax starting in 2027. The Ministry intends to rely on data from the Building Electronic Identity—a digital record containing verified structural and usage details—to determine tax liability based on actual surface area and current use. If an inspection reveals that a property’s real size exceeds what appears in official documents, the tax will be calculated on the verified square meters. Conversely, where the Building Electronic Identity shows a smaller area than older records, the figure from the identity will prevail.
No penalties are foreseen for past omissions under the new regime.
