How do you get an AFM tax number in Greece in 2026?

AADE guidance steers natural persons, including non-residents and foreigners, to the digital myAADE portal and the TIN & Authentication Key application. You submit personal details, contact email and phone, and supporting identity information online. The same filing is designed to issue both the AFM and the Kleidarithmos (Authentication Key) used for later TAXISnet and myAADE login setup.

Identity confirmation is not skipped. Official routes include a myAADElive video appointment or physical presence at a competent Tax Office / KEFODE linked to the address you declare. A legal or tax representative who already holds Greek credentials can file for you when representation documents meet AADE rules, including apostille and translation where foreign powers of attorney are used.

Treat blog timelines as rumours. Follow the live myAADE checklist and the confirmation email AADE sends after verification.

With an AFM you can accept an electronic lease declaration, open many Greek bank conversations, and start AMKA and healthcare steps that assume a tax ID exists. Activate digital access as soon as codes arrive: Set up TAXISnet. Address evidence for later police or KEP visits still depends on a real lease or host declaration: Register your address.

EU citizens still need a separate registration certificate after three months; third-country nationals still need a residence title. The AFM does not replace either path: EU residence certificate and Apply for a residence permit.

Confusing the AFM with AMKA is the classic mistake. AFM is tax; AMKA is social security and health access. Another trap is stopping after the online form without finishing myAADElive or the DOY visit. Banks and landlords will wait for the issued number, not a screenshot of an unfinished application.

Non-residents can often obtain an AFM before moving, yet Greek mobile numbers and local address proof still matter for later banking and contracts: Open a bank account.
