Tax returns 2026: How many taxpayers owe additional tax and how many are due a refund
Already 8 in 10 households have hit the submit button, with 1 in 3 required to pay additional tax and nearly 7 in 10 either paying nothing at all or receiving a refund.
Specifically, the latest data shows that more than 5.55 million returns have been submitted out of an estimated total of approximately 6.9 million expected this year. Based on the tax settlement notices issued so far:
- 33.81% of returns are showing a tax liability, with the total additional tax owed exceeding €3.5 billion — averaging €1,866 per taxpayer. Taxpayers must make their payment by July 31, 2026, either as the first of 8 monthly installments or as a lump-sum payment with a discount: 4% for those who filed their original return by May 15, 3% for those who filed between May 16 and June 15, and 2% for those who file by July 15, 2026.
- 30.49% of returns are showing a tax credit, with the total refund amount reaching €514.5 million — averaging €304 per taxpayer.
- The remaining 35.7% of returns are zero-balance filings.
Amended tax returns: How to correct errors without penalty before the July 15 deadline
With the tax return filing deadline set for July 15, 2026, taxpayers who have discovered errors or omissions in their original return can proceed to amend, supplement, or delete information — which in some cases can significantly reduce their tax bill. If an amended return is submitted before the filing deadline of July 15, 2026, the taxpayer will not be subject to any penalty whatsoever.
Regarding the amendment process, all data from the original forms (E1, E2, E3) are automatically carried over to the new form, and the taxpayer only needs to modify the specific fields they wish to correct. The new return, incorporating any additions, deletions, or corrections, will replace the original filing, and the tax liability will be recalculated based on the final income or deemed income data.
The updated tax settlement notice, which will be generated and posted to the taxpayer’s account on the myAADE.gr online portal, will display not only the result of the amended return assessment, but also the result of the original return assessment for comparison.
