Greece's Digital Client Register and accommodation in 2026: does it apply to hotels and rented rooms?

Updated 8 November 2026

Many hoteliers in the Cyclades ask whether they already have to record every guest in AADE's Digital Client Register. This guide sums up what has been officially published up to 8 November 2026, with the sources at the end. The short answer: we found no decision making it mandatory for accommodation. It is not legal advice: for a specific case, ask your accountant.

The short answer

As of 8 November 2026, the only AADE decision on the Digital Client Register we found is A.1057/2025, and it covers vehicle-related sectors only. We found no AADE decision, Government Gazette (ΦΕΚ) issue or announcement bringing in hotels, rented rooms, tourist furnished residences or short-term rental properties with an AMA.

For accommodation there is currently no start date, no optional period and no Digital Client Register fine.
Financial press reports in 2026 mentioned plans to extend it to hotels and rented rooms; we could not confirm this in an official source.
AADE's 2026 Operational Plan (A.1100/2026) mentions the Digital Client Register only as a 2025 result (17.4 million transactions), with no new sectors or dates.

Which decision governs it today

Decision A.1057/2025 of the AADE Governor (Government Gazette B 1828/14.4.2025) was issued under the Tax Procedure Code (Law 5104/2024). It sets:

Optional use until 30 June 2025 and mandatory use from 1 July 2025.
Obliged businesses: vehicle repair shops and body shops, alarm and audio installers, car parks, car washes, and rental of cars, motorcycles, commercial and agricultural vehicles.
The decision's annex lists the activity codes (ΚΑΔ); it includes no accommodation codes (55.xx).
We found no later amendment or extension of the decision.

Hotels, rented rooms and short-term rentals

Neither decision A.1057/2025, nor AADE's FAQ (January 2026 edition), nor the project's operational analysis mentions accommodation. This holds for every type:

Hotels with a Special Operating Licence or operating notification: no Digital Client Register obligation today.
Rented furnished rooms and tourist furnished residences: no obligation today.
Short-term rentals with an AMA: we found no mention. Their own obligations in the Short-Term Rental Property Registry apply, not the Digital Client Register.
If AADE issues a decision for accommodation, it will itself set who is covered and from when; we cannot predict it.

How it works where it applies

So you know what to expect, this is how it works in the vehicle sectors under A.1057/2025. A future decision for accommodation may set different fields and timings.

Each entry is made in real time and in any case before the service starts; AADE returns a unique registration number.
Recorded data include the establishment, vehicle details, date and time of entry, type of service and agreed amount.
The entry is completed when the invoice or receipt is issued: the myDATA MARK, or the receipt data from the fiscal device, is recorded.
A wrong entry is cancelled and entered again; the new one gets a different number and is linked to the cancelled one.
If the connection is lost, the data are entered without delay once it is restored.

Channels

Today AADE offers:

The «Ψηφιακό Πελατολόγιο» web application in myAADE, with special access codes created in the myDATAusers app, where authorised employees are also set up.
A REST API for businesses with computerised systems (ERP or commercial software).
We could not confirm in an official source any channel through myBusinessSupport, through e-invoicing providers or through a mobile app.

Fines

A.1057/2025 states that, for vehicle rental businesses, each entry is an information declaration and a late, incomplete or missing entry is penalised under Article 53(1)(a) of the Tax Procedure Code. According to AADE circular E.2059/2025, the fine under that provision is 100 euros per violation. For accommodation there is no Digital Client Register fine, since there is no obligation.

Link with the climate resilience fee

We found no official source linking the Digital Client Register to the climate crisis resilience fee. The fee applies on its own: the guest pays it per night and the property collects it with a special receipt, under AADE decision A.1202/2024.

What to do now

No action is needed for the Digital Client Register. If you want to be ready for a possible extension:

Make sure every booking ends in an invoice or receipt correctly transmitted to myDATA; where the register applies, it is linked to the MARK.
Ask your PMS or software provider whether it can connect to an AADE API.
Keep an eye on AADE's Digital Client Register page, where decisions and FAQs are published.

Why this also matters for AI

When a traveller asks ChatGPT or Gemini about a place to stay in Naxos or Santorini, the AI cross-checks what it finds online. A property with clear, current and consistent details everywhere earns more trust.

How iQuota helps

The official page iQuota publishes for each property shows its details and registration number, with structured data search engines read, and takes direct bookings. It does not replace any tax obligation, and we cannot guarantee that an AI will recommend you.
