A guide from mamaXO — rental management in Athens

Printing your lease from Taxisnet (myAADE): the certificate the bank asks for, in 2 minutes

Sign in to myAADE and open Εφαρμογές → Φορολογικές Υπηρεσίες → Ακίνητα → Δηλώσεις μίσθωσης ακινήτων → Είσοδος στην Εφαρμογή. Pick the filing year and your lease’s row. Click «Αποδεικτικό (PDF)». That PDF is the proof of declaration — what banks, ΔΕΗ and ΔΥΠΑ (the former ΟΑΕΔ, for the housing benefit) mean by "your lease from Taxisnet". Not listed? Change the year and check the "as tenant" tab.

Hand us the flat and get rent every month: the tenant, the ΑΑΔΕ paperwork and the phone calls are ours. We are paid only out of rent that arrives.

My lease is not in the list — what now?

Almost every empty list has one of these causes. Check them in order:

  • Wrong year or wrong tab

    The list shows the filing year, not the year the tenancy started. Try the previous year and both the "as tenant" and "as landlord" tabs.

  • The tenant has not accepted yet

    The owner filed, the tenant has not accepted. The declaration shows as pending. Its certificate prints, but without the acceptance status offices look for. The deadline and what happens after it are in the table below.

  • An old paper contract

    Leases stamped at the tax office before electronic filing existed are not in myAADE. No certificate can be issued. Ask the owner to declare the lease now. If it has expired, sign a new one.

  • Filed by a co-owner or an accountant

    The declaration appears in the account of whoever filed it. The other co-owners see it in the "as landlord" tab. One certificate covers all co-owners — ask for the PDF.

  • Active and inactive leases

    A lease that ended or was terminated appears without the yellow marker. Its certificate still prints. But ΔΕΗ and ΔΥΠΑ usually want an active lease — which means a new contract and a new declaration.

The rental agreement prints ready to sign, with every detail the declaration asks for. The declaration then takes ten minutes.

What do I need for the declaration?

  • The owner’s Taxisnet credentials.
  • Your tax number (ΑΦΜ) and the tenant’s. The tenant has no ΑΦΜ?
  • The date the agreement was drawn up, its duration, and the total monthly rent.
  • The property’s ΑΤΑΚ (the property’s 9- to 11-digit number from the Ε9 form) — an optional field. With it the address, floor and square metres come through from the Ε9 on their own; without it you type them in.
  • The number of the ΠΕΑ. (energy certificate)

How do I declare the lease to AADE?

The owner files it. About ten minutes, if the details are in front of you.

  1. Sign in to myAADE

    From gov.gr: "Property and taxation" → "Property leases". Or go straight to the AADE application. Sign in with the owner’s Taxisnet credentials.

  2. Start a new lease declaration

    In the leases application, choose to submit a new declaration of lease information.

  3. Fill in the details

    Owner and tenant ΑΦΜ, the date the agreement was drawn up, start and end dates, the total monthly rent, the ΠΕΑ number. The ΑΤΑΚ is optional and simply pulls the property details through from the Ε9. These must match the signed agreement. A mismatch here is the single most common mistake.

  4. Submit

    Check and submit. The proof of declaration is issued at once. The tenant is notified in their own myAADE account to accept it.

Or don’t log in to myAADE at all

The same steps, done by us, on time, with details that match the signed lease.

What is your deadline?

The declaration is due by the end of the calendar month following the start of the lease. Enter your start date to see your own.

One message before the deadline — no calls, no newsletters.

How does the tenant accept the lease?

The tenant accepts in their own myAADE account, with their own Taxisnet credentials. Same application, "declarations where you are the tenant" tab, «Αποδοχή» button. The notification arrives in the myAADE inbox and by email.

Acceptance by the tenant: 30 days from notification to accept or reject; with no action the declaration counts as accepted. For declarations filed from 02.06.2025.

Ending, renewing, amending: what is declared in myAADE?

The end of a tenancy — on time or early — is declared in myAADE too. Left undeclared, the lease stays active and rental income keeps being pre-filled for a flat that may be empty. A change of rent or term: an amending declaration. New terms or a new tenant: a new rental agreement and a fresh declaration.

Renewing, or a new tenant? The new lease takes a few minutes

Enter the details once. The contract prints in two copies, ready to sign and to declare.

Frequently asked questions

How do I print the lease from Taxisnet?
Sign in to myAADE, open the lease declarations, pick the filing year and the property’s row, and click «Αποδεικτικό (PDF)». That PDF — the proof of declaration — is the "lease from Taxisnet" that ΔΕΗ, banks and ΔΥΠΑ ask for. The tenant prints it from the "as tenant" tab, with their own credentials.
Where do I find my lease in Taxisnet?
In myAADE, with your Taxisnet credentials: Εφαρμογές → Φορολογικές Υπηρεσίες → Ακίνητα → Δηλώσεις μίσθωσης ακινήτων → Είσοδος στην Εφαρμογή. Pick the filing year (not the year the tenancy started) and the "as tenant" or "as landlord" tab. The lease’s row shows the registration number and opens the «Αποδεικτικό (PDF)».
Is the "lease certificate" the same as my rental contract?
No. The contract is the agreement you signed. When a bank or ΔΕΗ asks for "the lease from Taxisnet", they mean AADE’s proof that the lease was declared. That is the PDF this guide prints.
What does "active lease" mean in AADE’s records?
A lease that has neither expired nor been declared as ended. In the myAADE list it carries a yellow marker. An expired lease stays in the list as inactive and its certificate still prints.
How is the lease declared when the property has several owners?
One co-owner files it, stating the ownership shares. The income is then split proportionally in each owner’s tax return. If the Taxisnet credentials belong to another co-owner, that person — or an accountant — files it.
Can I declare the lease without an accountant?
Yes. You file it yourself in myAADE with your Taxisnet credentials. Accountants are usually needed by people with no credentials, non-residents for example, or with complicated co-ownership.
What is the electronic lease (ηλεκτρονικό μισθωτήριο)?
The electronic lease is the declaration of lease details the owner files in myAADE. It replaced stamping the paper contract at a tax office. The private agreement is still signed as before, without a notary. Then both parties’ ΑΦΜ, the term, the rent and the ΠΕΑ are declared — the ΑΤΑΚ optionally. The tenant accepts the declaration.
What if the declaration has a mistake in it?
The owner files an amending declaration. What matters is that the declared details match the signed agreement. The mismatch is what causes trouble later.

General information, not legal or tax advice. AADE procedures and deadlines change. Confirm them in the application before you file.
