Germany Tax Residency Rules: The 183-Day Test
183-day threshold
How the 183-day rule works in Germany
Germany triggers tax residency through habitual abode (roughly 6 months) or maintaining a dwelling.
Calendar year (January to December). This means your day count resets every January 1. Days from the previous year do not carry over.
If you exceed 183 days, Germany may tax your worldwide income as a tax resident. The exact consequences depend on your personal situation, any applicable tax treaties, and the type of income involved.
How the count works
Germany has two independent residency tests, written into §§8 and 9 of the Abgabenordnung. The "Wohnsitz" test treats you as resident if you maintain a dwelling in Germany under circumstances suggesting you will keep using it. Alongside it, the "gewöhnlicher Aufenthalt" (habitual abode) test catches a continuous stay of more than six months, with short trips away generally not breaking the chain.
What counts as a day
The six month habitual abode test runs on continuous presence, so brief departures like a weekend abroad or a short holiday usually do not interrupt the count. A clear, definitive departure does reset it.
Beyond the day count
The Wohnsitz test is what makes Germany unusual. Keep a furnished apartment in Germany that is available for your use, and the Finanzamt can treat you as resident on that basis alone, regardless of how few days you actually spend in the country.
Special tax regimes
Germany does not offer a special expat regime. Residents pay progressive income tax on worldwide income, topping out at 45%, plus the solidarity surcharge and church tax where applicable. Cross border workers can claim limited deductions for running two households, but that is about as far as the relief goes.
Tax treaties
Germany has a wide treaty network using the standard OECD tiebreaker. Because the domestic Wohnsitz test puts so much weight on a permanent home, the "permanent home" arm of the OECD test usually decides dual residence disputes.
Frequently asked questions
Can renting a German apartment make me a tax resident?
Yes, if the dwelling is genuinely available to you and the surrounding circumstances suggest you intend to keep using it. The practical test the Finanzamt applies is whether the place is ready for your next stay (keys with you, personal effects still inside, no one else living there). A genuine sublet to a third party usually moves you outside the Wohnsitz test.
Does the six month habitual abode test reset every January?
No. The clock runs continuously across the calendar boundary, so a single stay from October to April can establish residency even though neither calendar year by itself crosses 183 days.
Are there short term exceptions for tourists or business visitors?
Yes. A stay of up to six months that is purely for visiting, recovery, or similar private purposes will not establish habitual abode. The moment work enters the picture, even just working remotely from Germany for your foreign employer, the analysis tightens up.
