Greece is preparing for major changes in how rent is paid and declared, as a new law will eliminate cash payments for all residential leases beginning January 1, 2026. The measure applies to both new and existing rental agreements and aims to modernize the country's rental system by promoting transparency and consistent tax reporting.Mandatory bank transfers for all rent Under the reform, part of Law 5222/2025, rental payments will be allowed only through a bank account that has been officially registered with Greece's Independent Authority for Public Revenue (AADE). Cash handovers, which are still common in parts of the rental market, will no longer be recognized as valid payments. Landlords who continue receiving rent outside the banking system will lose a 5% tax deduction related to property damage and depreciation. Tenants who persist with off-the-books payments may become ineligible for certain state benefits and allowances.
