One in three taxpayers wins disputes with Greek tax authority, report finds
The Independent Authority for Public Revenue (AADE) said complaints filed with its Directorate for the Resolution of Tax Differences rose by 80% compared with 2024, exceeding 11,000 cases — the highest level in nearly a decade.
The directorate, known as DED, provides a free online review process for taxpayers contesting taxes or fines and is a mandatory step before cases proceed to court. Authorities said 99.2% of cases were processed within the 120-day legal deadline, the best performance since the service was established.
However, 83% of complaints were rejected in 2025, largely due to a wave of mass filings challenging “imputed income” rules. Excluding these cases, the success rate for taxpayers remained stable, with roughly one in three appeals upheld.
The rulings were backed by a 2025 decision of the Council of State, which found the contested tax framework constitutional and dismissed collective challenges.
AADE said many successful appeals involved errors in tax audits or filing procedures. The dispute resolution process has proven particularly valuable for individuals and small businesses seeking to avoid lengthy and costly court proceedings.
