How to File Your E1 on myAADE: A Step-by-Step Guide in English

Short answer: The E1 is filed online on myAADE, the tax authority’s portal, using your TAXISnet username and password. You open the income tax return for the right tax year, check every pre-filled figure against your own documents, add anything missing (foreign income in particular), and press final submission. The system then issues your tax assessment on the spot. The portal is in Greek, so the steps below give you the Greek labels to look for.

This guide is the practical, screen-by-screen side of filing. If you are not sure whether you need to file at all, or how foreign income and residency affect the result, start with our E1 guide for expats.

Before you start: what you need

• Your TAXISnet username and password. These are the same credentials you use for all AADE services. If you only have an AFM and never activated online access, sort that out first. Our AFM guide explains how.
• Your IBAN registered in myAADE. It must be active and in your name, or a refund cannot be paid.
• Your income documents for the year: employer certificates, pension statements, rental contracts, bank interest, and anything earned abroad.
• Last year’s return, if you filed one. It is the fastest way to spot what changed.

Remember which year you are filing for. The return filed in 2026 covers income earned in 2025. People mix this up all the time, especially in conversations with their accountant or bank.

Step 1: Log in and find the income tax return

1. Go to the AADE website and open myAADE.
2. Log in with your TAXISnet username and password.
3. Go to Εφαρμογές (Applications), then Φορολογικές Υπηρεσίες (Tax Services).
4. Open Δήλωση Φορολογίας Εισοδήματος ΦΠ (Income Tax Return, Individuals).
5. Choose the tax year. For the return filed in 2026, that is 2025.

The application holds three forms. The E1 is the main return. The E2 is for rental income and the E3 for business or freelance income. If you have either of those, they are filled in first, and their totals flow into the E1.

Step 2: Read the pre-filled return line by line

Most returns now arrive partly or fully pre-filled with data AADE already holds: salaries and pensions from employers, tax already withheld, some bank data, and property details. Pre-filled does not mean correct. This is the step where most mistakes happen, and where most money is lost or saved.

Check at least these:

• Salary or pension, and the tax withheld, against your employer or pension certificate
• Bank interest, against your bank’s annual statement
• Rental income, against your actual contracts, not just what was registered
• Dependants, including each child’s AFM, which is now requested in its own field
• Your IBAN, active and in your own name
• Your address and personal details

If a figure is wrong, correct it before you submit. Once the return is final, fixing it means filing an amended return.

Step 3: Add what the system does not know

AADE only pre-fills what Greek sources report to it. It does not know about:

• Income from abroad: a foreign salary, pension, dividends, or rent from a property in another country. Greek tax residents declare worldwide income.
• Foreign tax already paid, which you may be able to credit so you are not taxed twice
• Deductions and credits you are entitled to, such as donations or certain medical expenses, if they are not already there

This is also where the most expensive expat mistake happens: the residency code. Code 319 on the E1 marks you as a tax resident of another country who is filing in Greece only for Greek income. If you actually live in Greece and meet the residency rules, ticking it is wrong, and correcting it later is slow. Settle your residency status first. Our guide to the 183-day rule explains how it is decided.

If you file as a non-resident, the return now asks for your country of tax residence, your foreign tax number, and your full foreign address in Latin characters. Missing any of these can hold the return up.

Step 4: Submit and download your assessment

When everything matches your documents, choose Οριστική Υποβολή (Final Submission). The system immediately issues the Πράξη Διοικητικού Προσδιορισμού Φόρου, the tax assessment most people call the ekkatharistiko. It shows whether you owe tax, get a refund, or are at zero.

Download and keep:

• the submitted E1, plus the E2 or E3 if you filed them
• the tax assessment (ekkatharistiko)

You will need them for banks, residence permit renewals, mortgage applications and next year’s return.

Step 5: Pay, or wait for the refund

If you owe tax, the assessment shows the amount and the payment code. In recent years AADE has allowed payment in full with a small discount for early filers, or in up to eight monthly instalments starting at the end of July. The exact discount and dates change each year, so check the current announcement rather than last year’s rules.

If you are due a refund, it goes to the IBAN registered in myAADE, which is why that field matters.

Missed the deadline, or found a mistake?

The 2026 season, for 2025 income, closed on 24 July 2026 after AADE extended the original 15 July date. You can still file after the deadline, through the same application on myAADE.

• A late original return carries a fixed penalty of €100 under the Tax Procedure Code, whether you owe tax or not. If you do owe tax, interest for late payment is added on top.
• An amended return (τροποποιητική) is how you fix an error in a return already filed. If the original return was on time, a later correction often carries no fixed penalty, although any extra tax still attracts interest. The rules have exceptions, so check your case before you file.

The sooner you file, the smaller the interest. And a missing return tends to surface at the worst moment, such as a residence permit renewal or a property sale.

Would you rather not do it yourself?

You do not have to share your password with anyone. In myAADE you can authorise a specific accountant to file for you, limited to that job. That is how we work: you grant the authorisation, a licensed Greek accountant (OEE member) checks every pre-filled figure, adds your foreign income correctly, and files. You receive a plain-English summary of what was filed, what you owe or get back, and when to pay.

E1 filing from €40. Late returns and corrections are quoted after we see your situation.

Frequently asked questions

Can I file the E1 in English? No. myAADE is in Greek. You can use the Greek labels in this guide to find your way, or authorise an accountant to file for you.

Where exactly is the E1 on myAADE? myAADE, then Εφαρμογές (Applications), then Φορολογικές Υπηρεσίες (Tax Services), then Δήλωση Φορολογίας Εισοδήματος ΦΠ. Choose the tax year you are filing for.

Is TAXISnet the same as myAADE? They use the same login. TAXISnet is the name of the credentials and the older system; myAADE is the portal where you file today.

My return was submitted automatically. Is that a problem? AADE can auto-submit some pre-filled returns for people who took no action. The figures are still only what AADE knew. If you had foreign income or anything else missing, file an amended return.

What is the penalty for filing the E1 late? A fixed €100 under the Tax Procedure Code, whether you owe tax or not, plus late-payment interest on any tax due.

Can someone file my E1 without my TAXISnet password? Yes. In myAADE you can authorise an accountant to act for you on that specific return. Never send your password to anyone.

When does the next filing season open? For 2026 income, the platform usually opens in the spring of 2027. In 2026 it opened on 16 March. Watch for AADE’s announcement.
