German Tax Residency: When Do You Become a Tax Resident?

The short answer
You become a German tax resident the moment you have a home (Wohnsitz, a residence you keep and can use) in Germany — in practice marked by your address registration (Anmeldung) — or when you spend more than 183 days in Germany within a calendar year. Tax residents face unlimited tax liability (unbeschränkte Steuerpflicht): Germany taxes your worldwide income. If you have no German home and stay under 183 days, you are only taxed on German-source income (limited liability, beschränkte Steuerpflicht).
The two tests that create tax residency
A home (Wohnsitz). Keeping a residence in Germany that is continuously available to you — a rented or owned apartment where you actually live. The practical trigger is the Anmeldung (address registration at the local Bürgeramt, the citizens' office): once registered, the Federal Central Tax Office (Bundeszentralamt für Steuern) mails you your tax ID (Steuer-ID), an 11-digit number you keep for life. From the day a German home is available to you, you count as a resident — even if you travel frequently.
More than 183 days of physical presence (gewöhnlicher Aufenthalt). A long project, a secondment, or extended visits adding up to over 183 days in a calendar year also make you a tax resident, even without a German home. Germany applies the 183-day test per calendar year, not per stay.
What unlimited tax liability means
Your worldwide income becomes taxable in Germany — salary, freelance earnings, dividends, interest, and rental income from anywhere in the world. Germany's network of double-taxation treaties (Doppelbesteuerungsabkommen) decides which country gets to tax first and how the other avoids taxing you twice: typically Germany exempts the foreign income or credits the foreign tax against your German bill. If you earn income abroad, keep proof of the tax you paid there — the Finanzamt (your local tax office) will want to see it.
When you are only a limited taxpayer
No German home and fewer than 183 days in the year means limited liability (beschränkte Steuerpflicht): Germany taxes only your German-source income — for example, salary for work physically performed in Germany, rent from German property, or German dividends. Cross-border commuters and short-term assignees usually land here. Note that leaving Germany does not end residency by itself: you generally remain a resident until you give up your German home and actually leave.
What to do on arrival and departure
Register your address (Anmeldung) within 14 days of moving in — this is a federal rule, the same in every state.
Expect your Steuer-ID by mail a few weeks after the Anmeldung; give it to your employer so wage tax (Lohnsteuer) withholding is set up correctly.
Record your exact arrival and departure dates — the Finanzamt uses them to determine your residency period.
Deregister (Abmeldung) on permanent departure. A tax return is generally still due for the year you leave if you had German income that year.
Frequently asked questions
I registered my address but travel constantly for work. Am I still a tax resident?
Yes — as long as a German home remains available to you, the Wohnsitz test is met regardless of how many nights you actually sleep there.
Do the 183 days have to be consecutive?
No. It is the total number of days of physical presence within a calendar year that counts, including short repeated visits.
I live in Germany but work remotely for a foreign employer. Where do I pay tax?
As a German resident your worldwide income — including that foreign salary — is taxable in Germany. A double-taxation treaty may assign the primary taxing right to the employer's country for some of it, but you still report it on your German return.
I split my time between two countries. Which one wins?
The tie-breaker rules in the applicable double-taxation treaty decide, using a hierarchy: permanent home, center of vital interests, habitual residence, then nationality. Keep documentation of where your life is centered.
Does my employer need anything special once I'm a tax resident?
Give your employer your Steuer-ID and your tax class (Steuerklasse). With those, payroll withholding (Lohnsteuer) is calculated automatically through the ELStAM database — no separate registration needed.
If I keep my German apartment but move abroad for a year, am I still resident?
Generally yes — an available home keeps you a resident. People in this situation usually give up the apartment or sublet it properly and complete the Abmeldung to end residency cleanly.
