Germany has no headline non-dom-style tax regime. What it has instead is a clean, predictable residence test and a treaty network that, used correctly, produces sensible outcomes for cross-border movers. The first-year filing is where most cases either land cleanly or carry forward problems for years.
When German tax residence triggers
The two main tests for individual tax residence in Germany are:
-
Wohnsitz (domicile / habitual abode): maintaining a home in Germany under conditions suggesting you'll use it. Renting a Berlin apartment and registering Anmeldung is generally enough.
-
Gewöhnlicher Aufenthalt (habitual residence): continuous physical presence in Germany of more than 6 months, with interruptions of short duration not breaking the period.
Meeting either test triggers German tax residence on worldwide income.
The split-year reality
German tax residence typically starts on the day you move; income from before that day is treated under the prior residence and treaty rules. The mechanics for the first calendar year - what is German-taxable, what is treaty-protected, what is double-taxed and refunded - are case-specific.
Plan the move date around the calendar year. A move on 1 December is fundamentally different from a move on 1 July for that year's filing.
Treaty tie-breaker for the overlap year
Most cross-border movers spend part of the year residing in two jurisdictions. The treaty tie-breaker tests (permanent home, centre of vital interests, habitual abode, nationality) decide which country has the primary right.
A structured tie-breaker analysis up front is much cheaper than a refund claim two years later. We do this with the case before any move date is set in stone.
What gets double-counted and refunded
- Foreign employment income for periods during the overlap year - treaty protection often applies
- Foreign-source investment income - source country and Germany both want a piece in many scenarios; treaty credits and exemptions sort it out
- Realised capital gains during the move period - the exit-tax position of the departing country and the receipt position in Germany both have to be planned
Year-one filing
The German tax return for the move year is filed in the calendar year after the move (with standard extensions for cases supported by a Steuerberater). What needs to be ready:
- All foreign income with currency-converted equivalents
- Foreign tax paid with credit documentation
- Treaty positions clearly identified
- Family-related income separated cleanly
- Asset reporting where required
This is not a do-it-yourself filing for a year of cross-border movement. A German Steuerberater familiar with international cases is the right partner.
What we tell movers
- Decide the move date with the tax calendar in mind, not just the lease.
- Document the prior-country exit cleanly. The German side benefits from a clean closure on the other side.
- Don't move investment assets, accounts, or property positions in the months around the move without checking the tax implications - the wrong-day sale changes the bill.
- Engage the German tax adviser for the move year in the month of the move, not in April of the following year.
German tax residence isn't the headline jurisdiction for tax planning, but it is one of the cleanest to live inside if the first year is handled deliberately.
