Germany Tax Residency (6-month rule)

Q: Is German tax residency just a 183-day rule?

No. The habitual-abode test looks at one continuous stay of more than six months, not a running total of days inside a calendar year. The separate dwelling test can also make you resident with almost no days in Germany at all.

Q: Does keeping a home in Germany make me a tax resident?

It can, on its own. The test is whether a dwelling is available to you under circumstances suggesting you'll keep it and use it — ownership isn't required. A property kept only for occasional holidays after a genuine permanent move abroad generally doesn't count.

Q: Does registering my address in Germany make me a tax resident?

Not by itself. Registration at the residents' registration office is administrative, and the tax office looks instead at whether a dwelling is genuinely available to you or your stay is habitual. Deregistering doesn't end residency if the underlying facts haven't changed.

Q: What happens if I meet either test?

You become subject to unlimited tax liability, taxed on your worldwide income rather than only German-source income. Failing both tests instead leaves you with limited liability, generally covering income from German sources only.

Q: Can I be a German tax resident and a tax resident of another country at the same time?

Yes. German rules only settle your position under German law, and other countries apply their own tests. A double tax treaty between Germany and that country would then decide which one takes priority for specific income.

Key parameters
Threshold	6 months (effectively 183 days)
Period / Window	Continuous stay, not tied to a calendar year
Counting	Elapsed time, absences don't reset it
Alternative	Dwelling test (Wohnsitz)

Understanding the rule

You are a German tax resident — subject to what German law calls unlimited tax liability — if you meet either of two tests, in any order:

Dwelling — you have a home in Germany that you hold under circumstances suggesting you will keep it and use it. There is no day count, no minimum stay, and no requirement that it be your only home. Renting is treated the same as owning.
Habitual abode — you are present in Germany under circumstances showing your stay is not merely temporary. A continuous stay of more than six months always counts, from its first day.

Meeting either test makes you a German tax resident, taxed on worldwide income. Falling short of both makes you a nonresident, taxed only on German-source income.

The 6-month stay is not tied to the calendar year at all — it is one continuous stretch, wherever it happens to fall. A stay running from October to May counts exactly like one running from February to September. There is no separate rule for a stay that crosses a year-end: it is the same single continuous-stay test either way, which is the point people most often get wrong.

One exception narrows the 6-month rule: a stay taken exclusively for visiting, recuperation, medical treatment or similar private purposes, lasting no more than a year, doesn't trigger it automatically. You can still be found to have a habitual abode on the general test, and the dwelling test is unaffected either way.

How to keep track

Mark your arrival date. That starts the clock — you're not tallying individual days present the way most other countries' rules work, you're just watching the calendar run forward from that date.
Your threshold is the date more than 6 months later. No separate annual total, no reset at a year-end — the calendar just needs to run past that point while your stay continues.
Short trips away don't move that threshold date. A family visit home, a holiday, a business trip — the clock keeps running underneath them as if you'd stayed. In practice, a single absence longer than about 2-3 weeks stops counting as short-term and puts continuity at risk.
A stay-ending break resets everything. If a longer absence breaks the stay, a later return starts a brand-new arrival date and a brand-new six-month threshold — the earlier weeks don't carry over or add up toward it.
Cross the threshold without a break, and residency is backdated to your original arrival date in step 1, not to the date you actually crossed the line — so income from early in the stay is caught too.

Keep travel records covering the whole stay, plus documents showing whether a German home is available to you: a tenancy agreement, a title deed, or utility bills. Register-office paperwork on its own settles neither test.

Edge cases

Registering or deregistering at the residents' registration office doesn't decide it. Tax residency turns on the actual facts — whether a dwelling is genuinely available to you — not on your entry in the local register.
A property you barely use may or may not count. After a genuine permanent move abroad, keeping a home used only for short holidays or visits generally doesn't maintain residency. Keeping the home you previously lived in, unchanged and ready for use, points the other way.
Leaving can trigger a one-off charge on business shareholdings. Giving up German residency while holding a substantial stake in a company is treated as a deemed sale, taxing the built-up gain even though nothing was sold.
German nationals moving to a low-tax country can stay partly taxable for ten years. If you kept substantial German economic ties, and were fully taxable here for at least five of the ten years before leaving, an extended limited liability can follow you for a decade.
A part-year move splits your liability rather than removing it. Arriving or leaving mid-year makes you fully taxable for the resident part, and your foreign income from the rest of the year can still push up the rate applied to it.

If you get this rule wrong

Under-declaring income after wrongly assuming you weren't resident is tax evasion when deliberate, and a lesser administrative offence carrying a fine when merely careless. That distinction also sets the reassessment window — four years normally, five for a careless mistake, ten where evasion is found. Professional tax advice is strongly recommended in situations like this.

Examples

A stay that runs across the new year

You arrive in Munich in October on a contract and leave the following June — eight months in one unbroken stay, sitting in two calendar years. Because the six months don't have to fall inside one calendar year, you're a German tax resident, backdated to your October arrival.

A stay broken by a real return home

You work in Frankfurt from March to July, spend the next three months working back in your home country, then return in November. Neither block runs past six months on its own, and a three-month gap is a genuine break rather than a short absence, so the six-month rule isn't triggered.

A home kept behind while you live abroad

You live and work abroad and spend only a few weeks a year in Germany, but keep the apartment you always lived in, furnished and ready to use. Your day count is nowhere near six months, yet the dwelling test alone can make you a German tax resident, taxable on worldwide income.

FAQ

Is German tax residency just a 183-day rule?

Can the 6 months run across two calendar years?

Yes. German law measures a single continuous period, not a calendar-year total, so October to May counts just as much as February to September. Some guides describe this as "six months in a calendar year, or six months across a year-end" — that's just two ways the same single continuous-stay test can play out, not two separate rules. It's what catches people who assume they're safe as long as they stay under six months in each calendar year.

Do I need to stay in Germany without leaving for 6 months straight?

No. The law tolerates short-term interruptions — a family visit home, annual leave, a recuperation stay, or a business trip are all specifically recognised as not breaking the stay. "Short-term" isn't fixed in the statute itself, but in practice a single absence longer than about 2-3 weeks is generally too long to count as short-term, unless the surrounding circumstances still clearly show one continuous stay.

Is this a rolling 12-month window, like other countries use?

No. A rolling window tallies days present across a moving lookback period, so scattered trips can add up over time. Germany's test works differently — it needs one continuous stay running past six months, tolerating only brief interruptions inside it. Leave for long enough to break that continuity, and the clock doesn't carry over: a later stay has to build up its own six-plus months from scratch.
