Late lease declaration: the €100 fine

Open the service on gov.gr

The official ΑΑΔΕ service «Μισθωτήρια ακινήτων». The same application handles the declaration, the amendment and the termination — and the same deadline covers all three.

A lease declaration is due on myAADE (Taxisnet) by the end of the month after the tenancy starts (Circular ΠΟΛ.1162/2018). File it late and the fine is €100, however late it is (Law 5104/2024, άρθρο 53). A late termination filing costs the same. The landlord pays, not the tenant. Correcting a late filing draws no second fine.

Here, with nothing handed over: the free builder works out the filing deadline for your own start date. On the properties we run, watching that deadline is our job.

What is filed, by when, and what the delay costs

Three declarations, one deadline: the end of the next calendar month. It runs from the event — the start, the change or the termination — not from the day you signed or the day you remembered. A tenancy starting on 10 September is declared by 31 October; a termination dated 3 November is declared by 31 December.

What does each day of delay cost?

An example (παράδειγμα): the tenancy starts on 10 September. The dates are made up, the amounts are the law’s.

  1. 10 September

    The tenancy starts. The deadline runs from here, not from the signature.

  2. By 31 October

    Filed on time. No fine.

  3. 1 November

    One day late. €100.

  4. March, six months on

    Still €100. The amount does not grow with time.

Which is why the right move is to file today: waiting costs no more money, but your tenant has no certificate for as long as it waits.

  • Initial lease declaration

    By the landlord, by the end of the calendar month following the start. Late: €100, however many days.

    Circular ΠΟΛ.1162/2018, άρθρο 1 §1α · Law 5104/2024, άρθρο 53

  • Amending declaration (τροποποιητική)

    Same deadline, counted from the change. It can alter the term, the rent, the signature date and the ΠΕΑ (energy certificate) — anything else needs a new declaration. Late: €100.

    Circular ΠΟΛ.1162/2018, άρθρο 1 §1α · Law 5104/2024, άρθρο 53

  • Termination declaration (λύση)

    By the landlord, by the end of the month following the termination date. Without it ΑΑΔΕ treats the tenancy as running and attributes rent you are no longer collecting. Late: €100.

    Circular ΠΟΛ.1162/2018, άρθρο 1 §1α · Law 5104/2024, άρθρο 53

Who pays the fine — and what happens if you correct the filing

Filing is the landlord’s obligation, and the penalty follows the obligation. The tenant files nothing: they accept or reject the declaration made in their name, and they do not pay for your delay.

The landlord letting the property

The declaration, the amendment and the termination all go in under their own Taxisnet credentials, and the €100 sits with them — even when someone else caused the delay, a tenant who took weeks to obtain a tax number, for instance.

The tenant

They file nothing and pay no fine for your late declaration. Their part is acceptance within 30 days of the notification; if they do nothing at all, the declaration counts as accepted.

Several co-owners

One of them files and the others accept within the same 30 days. How the fine is shared when a property has several owners is something we could not confirm in a source we can name, so we do not state it — ask the tax office or your accountant.

Correcting a late initial declaration does not draw a second fine: the breach is one and has already been assessed. In practice a wrong ΑΤΑΚ (the property’s 9- to 11-digit number from the Ε9 form) or energy-certificate number in a late declaration is fixed without a new penalty — and there is no reason to leave wrong details where they are.

The guide shows where the declaration goes

The same myAADE screens take the initial filing, the amendment and the termination.

The deadline has passed — what to do today

The amount does not grow: €100 on day one of the delay is €100 in month six. What does grow is everything else. While the tenancy is undeclared your tenant cannot print the filing certificate the electricity company, the bank or the housing benefit asks for, and you have nothing to show if the tenancy is ever questioned.

Four steps

  1. Keep the real start date

    It is the date on the signed agreement, not today’s. A convenient date saves one fine and creates a second problem: your paperwork then says something different from your filing, and that is the first thing anyone checks.

  2. Collect what the declaration asks for

    Tax numbers for both sides, the energy certificate number, start and end dates, the monthly rent and the deposit; the ΑΤΑΚ is optional and fills the property details in. Without the tenant’s tax number the declaration cannot be submitted at all.

  3. File it on myAADE

    The menu path is: Εφαρμογές → Φορολογικές Υπηρεσίες → Ακίνητα → Δηλώσεις μίσθωσης ακινήτων → Είσοδος στην Εφαρμογή. The filing only counts once it is submitted for good — a saved but unsubmitted declaration does not exist as far as ΑΑΔΕ is concerned.

  4. Ask the tenant to accept it

    The notification waits for them under Μητρώο & Επικοινωνία → Τα Μηνύματά μου and they have 30 days. Silence counts as acceptance, but the certificate is what they need — so it is not something worth letting run out on its own.

The fine is assessed by the tax office. It is not paid inside the application and it does not block anything: the declaration goes through as normal and the penalty follows.

One decision cancelled the fine for a late termination filing where the same tenancy continued with the same tenant and a fresh declaration covered it (ΔΕΔ 1858/2026). That is one decision in one case — not a rule that applies to yours automatically.

The next lease does not have to be late

The free builder writes the agreement in three minutes, collects everything the declaration will ask for, and tells you the date by which it has to be filed.

Questions owners ask about the fine

How much is the fine for a late lease declaration?
One hundred euro for each late informational lease declaration, regardless of how many days late it is (Law 5104/2024, άρθρο 53). The same amount applies to a late termination filing.
Who pays it — the landlord or the tenant?
The landlord. Filing is their obligation and the penalty follows it. The tenant only accepts or rejects the declaration within 30 days, and pays no fine for it.
Was the fine the same in 2018 or 2019?
Until 18.04.2024 the amount sat in άρθρο 54 §2α of Law 4174/2013; from 19.04.2024 it sits in άρθρο 53 of Law 5104/2024. The figure we checked is the one in force today; which provision applies to a filing for an older year is not something we confirm — ask the tax office or your accountant.
If I file now for a tenancy that started last year, does the fine multiply?
The amount does not depend on how late the filing is. How many filings are outstanding is a separate question: each declaration that was never made is its own matter. How several old years are treated together is something we could not confirm in a source, so we do not state it.
I corrected a declaration that had been filed late. Will there be a second fine?
No, on the ΔΕΔ case law we checked: correcting a late initial declaration does not draw a new penalty, because the breach has already been assessed. The wrong detail is worth fixing.
I forgot to declare the termination. Does the fine apply there too?
Yes, on the same deadline: the end of the month following the termination (ΠΟΛ.1162/2018). Without it ΑΑΔΕ treats the tenancy as live and attributes rent to you. In one case where the tenancy continued with the same tenant and a new declaration covered it, the fine was cancelled (ΔΕΔ 1858/2026).
I let the flat with no written contract and no filing. What is the fine?
On the filing itself, €100 once it goes in late (Law 5104/2024, άρθρο 53). What undeclared rental income means is a separate body of rules that we do not judge here — talk to an accountant. In practice a tenancy with no paper and no filing also leaves you with no certificate and no leverage when something goes wrong.
Can the fine be cancelled?
In the decision we checked (ΔΕΔ 1858/2026) it was, in specific circumstances. We do not describe the appeal route or its deadlines here because we could not confirm them at a primary source: ask an accountant or a lawyer.
