Greece:AADE Meets Tax Office Reps on 2026 OSDE Declaration Progress

On 2 October 2026, AADE convened a virtual meeting with representatives of the Regional Tax Offices (ΚΥΔ) to review the progress of the 2026 OSDE (Special Declaration of Real Estate) submission cycle. As of the meeting date, over 2.3 million declarations had been submitted, representing a 12% increase compared to the same period last year. The discussion focused on recurring errors in property valuation codes, co-ownership percentage discrepancies, and the new mandatory fields for energy performance certificates. AADE emphasized the importance of the 31 October 2026 final deadline and announced enhanced helpdesk support, including a dedicated chatbot on the myDATA portal. The meeting also addressed the integration of OSDE data with the Unified Property Registry (ΗΜΤ) for automatic cross-checking against cadastral records.

Key Takeaways

  • Submission Momentum Strong: With 2.3 million filings, compliance rates are ahead of schedule, but a surge is expected in the final two weeks before the deadline.
  • Top Error Categories Identified: Incorrect property use codes (residential vs. commercial), missing energy certificate references, and mismatched co-owner TINs account for 65% of rejections.
  • Enhanced Support Measures: AADE has deployed 150 additional support staff and extended call center hours to 20:00 on weekdays and 14:00 on Saturdays until the deadline.
