All property leases in Greece are now subject to a system of digital oversight following a recent ruling by the Independent Authority for Public Revenue (AADE). This marks the initiation of the anticipated Real Estate Ownership and Management Registry (MIDAS).
For the first time, tenants and co-owners must accept or reject any new rental declaration submitted by the landlord via myAADE within 30 days. If no response is given, the lease will be deemed automatically accepted.
A transition period has been established until June 30, allowing for the confirmation or rejection of leases submitted by June 1, 2025. During this time, landlords can also terminate leases without penalty for agreements that expired by April 30, 2025.
This initiative introduces a new framework of “tax monitoring” over rental agreements. Previously, there was no requirement or deadline for tenants or co-owners to validate rental declarations. Now, each submission will trigger notifications via Taxisnet, email, and the myAADEapp, initiating a 30-day countdown from the moment of notification.
If neither the tenant nor co-owner responds, the system will lock the declaration as accepted, officially recording it in the tax registry. If the lease is rejected, a justification is necessary, putting an end to false declarations or unauthorized rentals by a single co-owner.
The grace period concludes on June 30 for leases submitted prior to June 1, 2025. AADE encourages users to resolve outstanding declarations to avoid penalties. During this timeframe, landlords can also report expired leases (up to April 30) without incurring fines.
This new process is more than a mere formality in myAADE; it paves the way for the full rollout of the MIDAS system, enabling tax authorities to know precisely who rents which properties and whether all parties have confirmed the lease with consistent terms.
AADE aims to eradicate unauthorized leases, forgotten contracts, and “phantom rentals”—properties rented but not registered with the tax office. For the first time, all parties involved must take action:
- Co-owners cannot be listed without their consent.
- Tenants can no longer be bound by leases with tampered terms.
- No one can submit a lease without addressing it.
This process will also put a stop to:
- Unauthorized subleases,
- Fake contracts used to claim benefits or evade taxes,
- Undeclared terminations lingering in an owner’s tax records.
It also addresses more “sophisticated” rental schemes, such as:
- Backdating rental declarations to escape scrutiny,
- Altering terms at renewal to artificially reduce reported income.
The era of “silent consent” has ended. Every lease now requires digital confirmation; otherwise, it will be automatically recorded in favor of the landlord, with no option for reversal.
