The process of filing tax returns for income earned in 2025 is entering its final stretch, as the deadline expires in 15 days for approximately 1.4 million taxpayers who have not yet filed their annual tax return, as well as for those who wish to correct errors and omissions in their initial return without incurring fines.
The deadline for filing income tax returns is July 15, and according to data from the Independent Authority for Public Revenue (AADE), 80% of households have already filed their returns.
Three out of ten taxpayers have received a tax bill, while the rest either owe no tax at all or are due a refund.
So far, more than 5.55 million tax returns have been filed out of a total of approximately 6.9 million returns estimated to be filed this year.
An “overview” of the tax assessments shows that:
- 33.81% of returns are due, with the additional tax already confirmed to exceed 3.5 billion euros, or an average of 1,866 euros. Taxpayers with a tax liability notice are required to pay by July 31, 2026, either the first of eight monthly installments or the full amount with a 4% discount for those who filed their initial 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 the returns filed are credit returns, with the total tax refund already reaching 514.5 million euros, or an average of 304 euros.
- The remaining returns (35.7%) show a zero balance, with no tax liability or refund due.
Express Refunds
Tax refunds for taxpayers with a credit balance are processed through an express procedure. Those who have no tax or social security debts or outstanding obligations will see the tax refund amount deposited into their bank account within one week of filing their return, while for those with tax debts, the Independent Authority for Public Revenue (AADE) offsets the tax refund against their outstanding debts.
Offsets are processed centrally on a weekly basis, while those that cannot be processed centrally are handled by the Tax Offices or the KEVEIS (Certification and Collection Center), without requiring the taxpayer to submit a refund request. In any case, a prerequisite for the refund of taxes to eligible recipients is the correct declaration of the IBAN account on the myAADE digital portal.
Income tax liabilities will be offset, as a matter of priority, against existing or future tax refund entitlements up to July 31, 2026; if the tax is paid through this offset, the taxpayer is entitled to the 2% to 4% deduction rate corresponding to the date of filing the return.
Corrections Without Penalties
Taxpayers who have filed their tax returns but subsequently discovered errors or omissions in the information may file amended returns by July 15 without risking penalties.
Additions or corrections to a specific line item on the return may reduce the tax liability for taxpayers. Please note that upon logging into the platform for amended tax returns, all data from the original forms (E1, E2, E3) are automatically transferred to the new form, and the taxpayer only needs to change the specific items they wish to modify.
Taxpayers have the option to correct any errors that may have occurred while completing their tax return or to fill in critical codes such as codes 787–788, which pertain to capital consumption, that is, income from previous years that they can claim to offset presumptive income and reduce their tax liability.
New Tax Return
After adding, removing, or correcting data, a new tax return will be generated to replace the original one, which will be voided. A new tax assessment will follow, incorporating the additional information, and the tax will be determined based on the final income or deemed income data.
The new tax assessment notice, which will be issued and posted to the taxpayer’s account on the myAADE.gr online portal, will include not only the result of the assessment based on the amended return but also the result of the assessment based on the original return.
If the amended return is filed by the deadline for filing tax returns—that is, by July 15, 2026—then the taxpayer will avoid the penalty.
