Key deadlines and requirements for tax filing and tax rebates and detected tax evasion.
4% discount on income tax returns until the end of April
Taxpayers have until the end of April to grab a 4% discount if they pay their income tax in full. The government’s set this deadline in stone, even though accountants have been nudging for an extension to the end of May. No luck with that so far.
Since mid-March, more than 1.65 million tax returns have already gone in. Of those, close to 193,000 came from self-employed individuals.
On 25 April, the tax authority will automatically submit another million pre-filled returns. It’s a big push to keep things moving.
Looking at the numbers, most people either don’t owe extra tax or are actually getting money back. About 46% of returns come out to zero tax owed. Then, roughly 24% get refunds, and the average is around €342.
The rest—about 30%—end up owing more, with the average bill landing at €1,503. The tax office has already paid out refunds to nearly 297,000 people, transferring over €69 million.
Just a reminder: if your IBAN isn’t up to date on the digital tax platform, you might miss out. Debt offsetting is rolling too, with more than 113,000 cases settled against refunds, totaling over €31 million.

Key Elements in Tax Declarations
- Pre-filled tax returns: Most info is already filled in to make life easier.
- Initial and corrective returns: Corrections are allowed (and penalty-free) from late April to mid-July.
- Calculated tax amount: The final number comes after the tax authority checks your return.
- Digital submission: Everything’s done through the myAADE portal, so you can skip the trip to the tax office.
Special Tax Situations
- Property owners need to include imputed income and any deductions for renovations.
- Taxpayers getting divorced usually file separately.
- Agricultural workers might be eligible for specific exemptions.
- Non-monetary benefits—like notional income from assets or lifestyle—fall under deemed income rules.
Tax Structure and Reliefs
The tax scale’s progressive, so low-income folks get a basic tax-free allowance. There are business tax exemptions and special rules for groups like freelancers and landlords. Business activity fees add some fixed costs on top.
Digital Platform and Services
The myAADE portal is central for:
- Giving you pre-filled data based on last year’s info.
- Letting you tweak your declarations if you spot mistakes.
- Managing refunds and debt offsets pretty quickly.
- Showing deadlines, amounts owed, and payment choices up front.
Compliance and Enforcement
If you miss deadlines, you lose discounts or get hit with penalties. There’s a window until mid-July for making changes without fines, so it’s not all-or-nothing. The authorities are keeping a close eye on income and assets to make sure tax liabilities are calculated right.
Retroactive Payments: Platform Opens for Amended Tax Returns
In May, the Independent Authority for Public Revenue (IAPR) is rolling out an online platform for amended tax returns. This one’s for people who got retroactive payments last year—think salaries, pensions, agricultural subsidies, or compensation from court cases.
The system logs these retroactive amounts and tags them to the right tax years in Taxis, under the personal income tax section. You can check your details by hitting “Income-Expenses-Tax Prepayment Update” in your account.
Once the platform’s live, just pick the amended returns option and the Retroactive Income E1 form. The retroactive amounts will already be filled in—just double-check and submit.
Tax on these payments gets calculated using the brackets and solidarity levy rates from the actual years the income belongs to. Any withholding tax already taken out (usually 20%) gets knocked off the total owed.
If you owe extra tax after the amendment, it’s due by 31 January 2026. Pensioners, though, can apply for a repayment plan—anywhere from 2 up to 48 monthly instalments, with interest, under the usual settlement scheme.
Some key points about taxing retroactive payments:
-
Retroactive wages, pensions, bonuses, and compensation paid in 2024 (based on laws, court decisions, or collective agreements) have to be taxed in the year they relate to—not just when you got paid.
-
This covers late pension payments and retroactive sums from social insurance too.
-
You’ll need to file amended returns for the actual years when you earned that income.
For example, if you got a pension back payment for 2022, it needs to show up on your 2022 return—even if you received it later. It’s all about matching the tax to when the money was technically earned.

Tax Evasion Uncovered €3.1 Billion – Significant Cases Also Found in Crete
In 2024, the Independent Authority for Public Revenue (AADE) uncovered illegal tax practices totaling €3.1 billion. That’s a staggering amount, linked to tens of thousands of offenders found through relentless investigations.
The cases ran the gamut—fake invoices, shadow companies set up just to dodge taxes, and more. Some offenders ran full-blown factories cranking out fake invoices. Others opened businesses that vanished overnight.
One pattern stood out: wealthy individuals claiming no income, while their bank accounts were flush with unexplained millions. There were also “invisible” online shops, running without tax IDs and selling goods under the radar.
Some companies looked tiny but cost the state huge sums. Single-shareholder private companies often started with a token euro, but somehow hid hundreds of thousands—or millions—from tax authorities. They took advantage of legal grey areas and weak oversight.
The AADE’s 2024 Annual Report dug into hundreds of big tax evasion cases, with the Services for Research and Assurance of Public Revenue (YEDDE) investigating. Common tricks included:
- Networks cranking out and receiving fake tax documents
- Companies trading goods or services using phony invoices
- Businesses operating without valid tax registrations

In Crete, investigators uncovered notable fraud cases that fed into the national total. The same kinds of schemes showed up—undeclared sales, unregistered businesses, the works.
This kind of widespread tax evasion really highlights how creative people get when dodging the system, and where monitoring falls short. AADE is ramping up data analysis and cross-checks to catch more offenders and, hopefully, close those loopholes.
