Germany pairs a strict day-count rule with an independent home-ownership test, meaning the safest-looking nomad strategy (never hitting 183 days) can still fail if you keep a German apartment on the side. This dual-trigger structure is one of the stricter setups on this list, and it catches people who assume that simply limiting their physical presence is enough to stay safe.

Spend 183+ days in Germany in a calendar year and you establish "gewöhnlicher Aufenthalt" (habitual abode) — both arrival and departure days count toward the total.
Separately, simply maintaining ANY dwelling available for your use in Germany (a Wohnsitz) triggers residency regardless of day count — this test doesn't care how many days you actually spent there.
Once the 183-day threshold is crossed, tax liability can apply retroactively to the start of your stay, not just from day 183 onward.
German tax residents owe worldwide income tax at progressive rates up to 45%, plus a solidarity surcharge.
There's no general nomad regime in Germany; a few favorable rules exist only for specific researcher or employee secondment arrangements.
A management consultant keeps a small one-bedroom flat in Berlin as a "home base" while traveling for eight months of the year on client engagements across Europe. He's physically present in Germany for only 95 days that year — nowhere near the 183-day threshold. But because the flat remains his to use whenever he returns (he hasn't sublet or given up access), German tax authorities can still treat him as a full tax resident under the independent domicile test, regardless of how few days he actually spent there.
Illustrative composite example for educational purposes — not a real individual or filed case.
A genuine, exclusive sublet — where you no longer have access to the property — generally removes the "available to you" element of the domicile test. Informal arrangements where you keep a key or return periodically are much riskier.
Yes — unlike some countries, Germany counts both your arrival day and your departure day as full days present.
Yes. Once you cross the 183-day threshold within a calendar year, tax liability can be assessed back to when your stay began, not just from the day you crossed the line.
A pure mail-forwarding address without any right to stay there is a weaker case for the domicile test than an apartment you could return to and sleep in — but the distinction can get contested, so document it clearly.
Whatever your risk level, a few concrete steps protect you better than guessing:
