How to Get a Greek Tax Number (AFM) from Abroad: 2026 Guide

The Greek Tax Registration Number (AFM) is strictly mandatory for overseas residents conducting business in Greece. Without it, you cannot sign a property deed, declare transfer taxes, or open a Greek bank account.

1. The AFM & The Non-Residents Tax Office

The AFM is the Greek equivalent of the US SSN/ITIN, Canadian SIN, Australian TFN, or UK UTR. It is issued by the AADE (Independent Authority for Public Revenue). For investors living abroad, jurisdiction falls to the Non-Residents Tax Office (known in Attica as KEFODE). Applications are processed exclusively online via the myAADE portal, either by you or your appointed representative.

2. Applying: Alone vs. Via a Representative

There are two primary ways to verify your identity and submit your application:

• Apply Alone: Submit the application on myAADE and complete identity verification via a video call (myAADElive).
• Via a Representative with existing AADE credentials (e.g., your lawyer or tax representative): They submit the file digitally on your behalf, requiring no video call or physical visit.
• Via a Representative using a new Power of Attorney (without pre-existing digital credentials): They verify your identity by physically attending the Non-Residents Tax Office.

A representative can be a lawyer, relative, or trusted associate. As an overseas resident, appointing a representative requires a notarial Power of Attorney (as digital or KEP signature certification is impossible from abroad). The document must contain explicit authority to obtain the AFM and receive the Taxisnet Access Code.

3. Mandatory Documents

Application Details: Full name, parents' names, date/place of birth, full overseas residential address, your home-country TIN (e.g., US SSN/ITIN, Canadian SIN, Australian TFN, UK UTR), email address, and telephone number.

Supporting Documents:

• Copy of a valid passport (or national ID for EU citizens).
• Notarial Power of Attorney (if applying via a representative).
• Formal Declaration of Acceptance signed by the representative.

4. The Taxisnet Access Code (Kleidarithmos)

The Access Code (Kleidarithmos) activates your credentials on Taxisnet, the central tax portal. Without it, you cannot pay taxes (such as the Property Transfer Tax) or file returns.

If you complete the video call personally, the code is sent directly to you via email/SMS. If you use a representative, KEFODE will only hand over the code if your Power of Attorney explicitly grants them the authority to receive it.
