Following a one-week extension, the deadline for submitting 2026 income tax returns in Greece has been moved from Wednesday, 15 July to Friday, 24 July. The extension—widely anticipated—comes amid ongoing delays in filings, despite strong overall progress. A significant number of declarations remain outstanding, and accounting firms are reporting heightened workloads.
Official Extension Announced
The Independent Authority for Public Revenue (AADE), which holds authority over deadline adjustments and official announcements, confirmed the extension on Friday, 10 July 2026. The additional time is strictly limited and intended as a final opportunity for late filers.
Filing Progress So Far
As of 9 July, AADE data shows that 6,001,433 E1 income tax declarations had been submitted. With this year’s total expected to reach approximately 6.9 million, roughly 898,500 returns remain pending.
Had the original 15 July deadline stood, completing the remaining filings would have required an average of around 150,000 submissions per day. With the new 24 July cutoff, that daily target drops to about 69,000—providing meaningful relief without unduly prolonging the tax season.
Breakdown of Submitted Returns
Of the 6.001 million declarations filed so far:
- 2,068,093 (34.46%) are tax liabilities — meaning the taxpayer owes money;
- 1,797,429 (29.95%) show a refundable balance;
- 2,135,911 (35.59%) report zero tax liability.
Tax amounts already assessed from liability declarations approach €3.95 billion, with an average tax burden of approximately €1,910 per liable return. Refunds total around €557.8 million, resulting in a net tax collection of over €3.39 billion.
Added Pressure from Corporate Filings
In addition to individual returns, AADE is separately monitoring income tax declarations from legal entities—including companies and other business structures. For accounting firms, the corporate filing period overlaps with numerous other tax and financial reporting obligations, reinforcing calls for a modest deadline extension.
Last Chance to File
The extension until 24 July serves as the final window for taxpayers who have yet to gather necessary documentation or finalize instructions with their accountants. Filers are strongly advised not to wait until the last day: a surge of hundreds of thousands of submissions in a narrow timeframe risks overwhelming both accounting professionals and AADE’s digital platforms.
It remains to be clarified—in AADE’s official decision—whether and how the extended submission deadline will affect payment due dates for income tax liabilities. The Ministry of National Economy’s stated aim is to conclude the entire process within July.
