Legal basis

Law 4172/2013 (ITC) Art. 4 §2

If you are physically present in Greece for more than 183 days in any rolling 12-month period, you become a Greek tax resident. The status triggers on day 184, and it backdates to your first day of presence in that window — so to stay off the day-count path, keep your presence at 183 days or fewer in every rolling 12-month stretch. The test comes from Law 4172/2013 (the Greek Income Tax Code), administered by the tax authority AADE.

Who it applies to

This matters most if you are:

• A remote worker, digital nomad, or frequent traveler spending long stretches in Greece.
• Someone splitting time across borders whose Greek stays add up across a year-end.
• An expat moving to or from Greece mid-year, where a 12-month window straddles the move.

It applies to individuals regardless of nationality — residency here is about physical presence (and, on other paths, your home and life ties), not citizenship or visa status.

The rule — and why it exists

Under Law 4172/2013, Article 4, paragraph 2, an individual is a Greek tax resident if present in Greece for more than 183 days in aggregate during any 12-month period. Two features make this rule stricter than a simple calendar test:

• The window rolls. It is any continuous 12 months, not the tax year — so the count never resets on 1 January.
• Residency backdates. Crossing 183 days makes you resident from the first day of presence in that window, not from the day you crossed the line.

Why it exists: countries use physical presence as a proxy for where your economic life actually sits. A rolling window closes the obvious loophole of splitting a long stay across two calendar years to keep each year under the limit.

Counting the days

1. 1Count every day you are physically present in Greece, including the days of arrival and departure.
2. 2The window is any rolling 12 consecutive months — not the calendar year, so the count does not reset on 1 January.
3. 3You cross the line on day 184 within any such 12-month window.
4. 4Once you exceed 183 days, residency backdates to the first day of presence in that window — not to the day you crossed 183.

Because the window rolls continuously, splitting a stay across a year-end does not help the way it can in calendar-year countries. Any 12-month stretch that adds up to more than 183 days can establish residency.

Examples

Example 1 — clearly resident by days

You spend 200 days in Greece between April and December. That exceeds 183 within a 12-month window, so you are a Greek tax resident — backdated to your first day of presence in April — and Greece can tax your worldwide income.

Example 2 — a split stay that a rolling window catches

You spend 120 days from September to December, then 100 days from January to April of the next year. Neither calendar year alone exceeds 183, but the rolling 12-month window from September through the following August totals 220 days — so residency is triggered.

Example 3 — tourism stay that stays exempt

You spend 200 days in Greece purely as a tourist, with a couple of short trips abroad. Because the time is exclusively for tourism, it falls under the up-to-365-day exemption and does not count toward the 183-day threshold.

Exceptions & edge cases

• Tourism and medical stays. Time spent in Greece exclusively for tourism or medical reasons is exempt for up to 365 days, including short breaks abroad, and does not count toward the 183-day threshold.
• Other residency tests still apply. Keeping your permanent residence, habitual abode, or centre of vital interests in Greece makes you a tax resident regardless of your day count. This rule only tracks the day-count path.
• Double-taxation treaties. If you are resident in two countries, the relevant treaty tie-breaker (permanent home → centre of vital interests → habitual abode → nationality) assigns a single treaty residence and divides taxing rights.

Common misconceptions

• "The count resets every January." False — the window is a rolling 12 months, so a stay spanning year-end is counted as one continuous stretch.
• "I'm only resident from day 184." False — residency backdates to your first day of presence in that window.
• "Under 183 days means I'm safe." False — a permanent home, habitual abode, or centre of vital interests in Greece can make you resident with any number of days.
• "Only Greek income is taxed." False — residency brings your worldwide income into scope, subject to any applicable treaty.
