Electronic lease declaration: what to prepare and how to proceed

The Lease Information Declaration on myAADE, step by step — what to prepare beforehand and what happens after you submit.

Updated 6 August 2026
Short answer

Lease information is declared through the relevant AADE service. Before starting, check which procedure applies to your tenancy and gather the property and agreement details.

Check the procedure that applies to your tenancy

Before you start

Gather five things.

Gather the required details first so you can complete the declaration carefully.

  • TAXISnet credentials — your own, as owner or lessor.
  • The tenant's ΑΦΜ — and their full name as it appears in the registry.
  • The property's ΑΤΑΚ — you will find it on your Ε9.
  • Check whether the property requires an EPC and which details must be declared. Ask the relevant engineer or accountant if you are unsure. Read the EPC guide.
  • Term and rent — as you agreed in writing, with start and end dates.
Step by step

Submitting, screen by screen.

Sign in to myAADE

With your personal TAXISnet credentials, from a computer or your phone.

Open «Lease Information Declarations»

You will find it under Applications. Click «New declaration».

Fill in the property

ΑΤΑΚ, address and type of lease (residence). The details must match your Ε9.

Lease and tenant details

Start and end dates, monthly rent, the tenant's ΑΦΜ. This is where a written agreement pays off: you copy, you don't remember.

Enter the EPC number

Check whether the property requires an EPC and which details must be declared. Ask the relevant engineer or accountant if you are unsure.

Submission and receipt

Check the summary and submit. Save the submission receipt (PDF) — that is your document.

After you submit

Three more things.

  • After submitting, check notifications and pending actions in the AADE application. Acceptance steps, deadlines and the effects of taking no action follow the current procedure.
  • Keep the submission receipt with your agreement. An organisation you present them to may request additional documents.
  • Made a mistake? It can be fixed — with an amending declaration, from the same place. At the end of the term or on early termination, you declare the termination of the lease in the same way.
Mini-FAQ

The fair questions, before you ask them.

Does an accountant have to do it?

Not necessarily — the declaration is designed for the lessor to file. But if your accountant already manages your properties, they can file it.

The tenant has no Greek ΑΦΜ?

They will need to get one — at the tax office or online. Start it early: it is the step that most often delays tenants from abroad. Confirm the process with your accountant.

When does it have to be submitted?

By the end of the month following the start of the lease. Check the deadline that applies to your tenancy and plan the submission in advance. Confirm the deadline for your own case with your accountant.
