Greece Tax Residency Guide 2026 — 183-Day Rule, ΔΟΥ Registration & Non-Dom Criteria

determining tax residency in Greece. The guide covers: the two criteria for tax residency under Greek law (Article 4 of the ΚΦΕ — Κώδικας Φορολογίας Εισοδήματος, Law 4172/2013 — the 183-day rule and the centre of vital interests), the 183-day rule (physical presence in Greece for more than 183 days in a calendar year — counted as any day spent in Greek territory, including weekends, holidays, and partial days; the burden of proof is on the taxpayer to demonstrate absence; the ΑΑΔΕ uses evidence including travel records, banking transactions, mobile phone data, and utility bills), the centre of vital interests (the hub of personal and economic interests — if your spouse and dependent minor children reside in Greece, or your principal economic activities and asset management are based in Greece, you are presumed to be a tax resident regardless of physical presence), the exceptions under double taxation treaties (the tie-breaker rules — permanent home, centre of vital interests, habitual abode, nationality, mutual agreement procedure), the process of becoming a Greek tax resident (obtaining the ΑΦΜ — Αριθμός Φορολογικού Μητρώου from the competent ΔΟΥ — Δημόσια Οικονομική Υπηρεσία office, registering on the TAXISnet system (www.aade.gr), obtaining a Taxisnet code for online filing, registering with the social security system — EFKA, and the registration deadline within 30 days of arrival), the process of ceasing Greek tax residency (submitting a tax residency cessation declaration to the ΔΟΥ, the exit tax implications for individuals with significant shareholdings or high net worth, the five-year look-back rule), the Non-Dom Regime eligibility criteria (the requirement of not having been a Greek tax resident in the prior 7 years, the €500,000 qualifying investment, the application process with the ΑΑΔΕ), the penalties for incorrect residency status (fines of 50-150% of underpaid tax, criminal charges for tax fraud exceeding €100,000), and the practical recommendations for expats and digital nomads.

Tax residency in Greece has significant consequences: residents are taxed on their worldwide income at progressive rates up to 44% (plus solidarity contribution up to 8%), while non-residents are taxed only on Greek-source income. All amounts in Euros (EUR). For related reading, see our Cross-Border Guide →.

Overview of the Two Residency Criteria

Under Article 4 of the ΚΦΕ (Law 4172/2013), a person is considered a Greek tax resident if either of the following criteria is met in a given calendar year:

Criterion 1 — 183-Day Rule: The person is present in Greek territory for more than 183 days during the calendar year. Days of presence include any day spent in Greece, regardless of the reason (holiday, business trip, layover).
Criterion 2 — Centre of Vital Interests: The person's centre of vital interests is in Greece — meaning the location of their principal economic activities, professional interests, or personal relationships (spouse and dependent minor children). This criterion can override the 183-day rule, meaning you can be a resident even if you spend fewer than 183 days in Greece.

If either criterion is met, the person is a Greek tax resident for the full calendar year and is taxed on worldwide income. If a double taxation treaty applies, the treaty's tie-breaker rules determine residency between Greece and the other country.

The 183-Day Rule

Counting days: Any day in which the person is present in Greece at any time counts as a full day. This includes days of arrival and departure, weekends, holidays, and business trips. Airport transit (without leaving the transit area) is generally not counted, though the ΑΑΔΕ may argue otherwise.
Evidence of presence: The burden of proving presence of fewer than 183 days is on the taxpayer. The ΑΑΔΕ uses: passport stamps, flight bookings, hotel receipts, bank and credit card transactions in Greece, mobile phone location data, utility bills, and social media geo-tagged posts.
Absences: Short absences from Greece do not reset the 183-day count. Only full calendar days spent outside Greece are deducted.
Temporary absence rule: Days spent outside Greece for economic reasons (e.g., a temporary work assignment abroad) may be excluded from the 183-day count if properly documented, but this exception is narrowly interpreted.

Centre of Vital Interests

Even if you spend fewer than 183 days in Greece, you may be a tax resident if your centre of vital interests is in Greece:

Personal interests: If your spouse and dependent minor children live in Greece, you are presumed to have your centre of vital interests in Greece unless you can prove otherwise.
Economic interests: If your principal business activities, professional practice, or asset management are based in Greece, you may be considered a resident. The ΑΑΔΕ considers the location of your business, the place where investment decisions are made, and the location of your bank accounts and assets.
Rebuttal: The centre-of-vital-interests test can be rebutted by providing comprehensive evidence that your personal and economic interests are concentrated in another country.

Exceptions — Double Taxation Treaties

When a person meets the residency criteria under both Greek law and the law of another country (dual residency), the applicable double taxation treaty determines residency. The tie-breaker rules under Article 4 of the OECD Model Convention apply hierarchically:

Step 1 — Permanent home: The person is a resident of the country where they have a permanent home (a dwelling available continuously).
Step 2 — Centre of vital interests: If a permanent home exists in both countries, residency is in the country where personal and economic relations are closer.
Step 3 — Habitual abode: If the centre of vital interests cannot be determined, residency is where the person spends more time.
Step 4 — Nationality: If the habitual abode cannot be determined, residency is the country of nationality.
Step 5 — Mutual agreement procedure (MAP): The competent authorities resolve dual residency by mutual agreement.

Becoming a Greek Tax Resident

The process of becoming a Greek tax resident involves several administrative steps:

ΑΦΜ (Αριθμός Φορολογικού Μητρώου): The Greek tax identification number. Obtainable from the local ΔΟΥ office or online via the ΑΑΔΕ portal. Required for all tax transactions, employment, property ownership, and bank account opening.
ΔΟΥ Registration: Register with the appropriate ΔΟΥ (tax office) for your area of residence. You will need your passport, proof of address (rental contract or property deed), and in some cases your residence permit.
TAXISnet: Register on the TAXISnet system (www.aade.gr) — the online platform for filing tax returns, viewing tax data, and managing tax obligations. You will receive a TAXISnet username and password.
EFKA registration: If you work in Greece (as an employee or self-employed), you must register with e-EFKA for social security.
Registration deadline: You must register with the ΔΟΥ within 30 days of your arrival in Greece.

Ceasing Residency and Exit Tax

Cessation declaration: To formally cease being a Greek tax resident, submit a declaration of tax residency cessation (δήλωση διακοπής φορολογικής κατοικίας) to your ΔΟΥ. Provide evidence of departure, new residence abroad, and the date of cessation.
Exit tax: If you have been a Greek tax resident for at least 7 of the last 10 years, the exit tax applies to unrealised capital gains on shares/securities if (a) the total unrealised gains exceed €4,000,000, or (b) you hold >25% of a company's capital with market value >€1,000,000. The tax can be deferred if you move to an EU/EEA country.
Final tax return: File a final annual tax return for the partial year of residency (January 1 to the date of departure).

Frequently Asked Questions

Can I be a tax resident in both Greece and another country?

Under domestic law, yes. Dual residency is possible when you meet the criteria in both countries. The applicable double taxation treaty resolves this using the tie-breaker rules. If no treaty exists, both countries may tax your worldwide income, with a foreign tax credit in one country to relieve double taxation.

Does owning property in Greece make me a tax resident?

No, property ownership alone does not make you a tax resident. However, owning a home in Greece is evidence of a "permanent home" and can support a residency finding under the 183-day test or the centre-of-vital-interests test. Property owners who spend fewer than 183 days in Greece and whose family and economic interests are abroad are generally non-residents, but must file non-resident tax returns for the property.

How does the ΑΑΔΕ verify days of presence?

The ΑΑΔΕ has access to a wide range of data sources: (a) border control records from the Greek police and Schengen Information System, (b) banking and credit card transaction data, (c) mobile phone records (cell tower location data), (d) utility bills showing consumption patterns, (e) travel records (flight bookings, ferry tickets, toll road payments), and (f) social media and internet data. The agency can cross-reference these sources to build a comprehensive picture of your movements.

What is the penalty for incorrectly claiming non-resident status?

If the ΑΑΔΕ determines you were a resident but claimed non-resident status, the penalties are: (a) a late-filing penalty of up to 15% of underpaid tax, (b) an additional penalty of 50-100% for serious infractions, (c) late payment interest at ~8% per year, and (d) criminal charges if the underpaid tax exceeds €100,000 (tax fraud).

How do I apply for the non-dom regime?

File an application with the ΑΑΔΕ by December 31 of the year following your establishment in Greece. Provide: (a) evidence that you were not a Greek tax resident in the prior 7 years, (b) proof of the qualifying investment (≥€500,000 in assets or ≥€50,000 in a Greek company/fund), (c) a commitment to maintain the investment for at least 5 years. The ΑΑΔΕ decides within 60 days.
