When Do You Become a Tax Resident in Germany?

(German Tax Residency Rules Explained for Expats Moving to Germany or Working in Germany)

One of the most common and important questions expats ask is:

“When do I become a tax resident in Germany?”

Many people assume tax residency in Germany starts after living there for 183 days. This is often called the ‘183-day rule in Germany’. This assumption is not entirely wrong, but German tax residency rules are broader and can apply much earlier than most expats expect.

The impact of tax residency can be significant for expats. As explained in a previous blog article, being a tax resident means Germany may tax your worldwide income, not just income earned inside Germany. Expats considered German tax residents will be subject to unlimited tax liability in Germany.

In this article, we want to use common expat situations that we are experiencing in our daily work to explain the legal triggers and implications for foreign residents coming to Germany.

German Tax Residency: The Legal Basis

The German income tax law (§ 1 Einkommensteuergesetz, EStG) mentions two criteria that will result in an expat becoming a German tax resident:

  1. You have a permanent home in Germany (Wohnsitz), or
  2. You have your habitual abode in Germany (gewöhnlicher Aufenthalt)

Please note that meeting just one of these criteria is sufficient to make you a German tax resident. The details for these terms are governed in general in a separate tax law, called Abgabenordnung (AO). Because the law itself is relatively broad in its wording which requires interpretation, German tax courts and the German Ministry of Finance have filled the gaps with their interpretations.

Permanent Home in Germany (Wohnsitz, § 8 AO)

You are considered a German tax resident if you maintain a place to live in Germany that is available to you at any time and that you intend to use. The law is not specific to what type of residence this should be. Therefore, expats need to be aware that such a home can also include:

Important points expats often overlook:

  • A rented accommodation can qualify; it does not have to be owned property.
  • Even a small apartment or second residence can qualify.
  • You do not need to stay there permanently. It is sufficient that the place is generally available to you.

Example: You move to Germany in March and rent an apartment, even if you still travel frequently or keep a home abroad. From the moment that the German apartment is available to you, you are usually considered a German tax resident.

Key insight: Tax residency often starts before you reach 183 days in Germany.

Habitual Abode in Germany (gewöhnlicher Aufenthalt, § 9 AO)

If you do not maintain a permanent home, residency may still arise based on physical presence.

You are deemed to have your habitual abode in Germany if you stay in Germany for more than 6 months / 183 days within a continuous period. The half-year period can even extend over two tax years, which would mean that you will be a tax resident for a portion of two years. Short interruptions by holiday or business trips abroad within these 6 months usually do not break the period. This is another way to become a tax resident in Germany without having a registered address.

This rule is often applied to expats with no permanent residence, such as:

  • Temporary work assignments, for example in construction,
  • Semester abroad for students or professors, for example research assignments,
  • Digital nomads staying long-term, for example bloggers, or
  • Project-based workers, for example professional consultants.

Permanent Home vs. 183-Day Rule — Which Applies First?

Many expats focus only on the 183-day rule, but in practical tax applications, both rules can trigger tax residency independently. Based on our experience, typical situations for expats are as follows:

  • You rent or own an apartment in Germany that is available for your private use.
  • You stay long-term without a formal residence, and the total time span exceeds 183 days.
  • You keep your primary residence in your home country, but due to work or studies you have a second home in Germany. Even though your primary residence is not Germany, you have created a dual tax residency.

This scenario leads us to the next question.

What Happens If You Keep a Home Abroad?

Having a residence in another country does not prevent German tax residency. You may become a dual tax resident, meaning two countries consider you a resident under domestic law.

In these situations, double taxation agreements (DTAs) determine where you are treated as resident for treaty purposes. For details, refer to our blog article about double taxation.

Important: Tax treaties help avoid double taxation, but they do not remove your German tax filing obligations.

Mid-Year Move to Germany

For expats living in Germany for a limited period, there is always a first year and a last year. This situation is common for expats relocating to Germany for work. If you move during the year, German tax residency typically begins when you establish your permanent home or habitual abode and ends when your home or habitual abode is terminated. In this case, the German tax office will consider you a German tax resident for only a portion of the year.

The key takeaways for expats moving mid-year are:

  • You may be considered a resident for only part of the year.
  • Tax filing in Germany is usually mandatory.
  • Your foreign income from the period before or during residency can usually be excluded from direct taxation in Germany.
  • Even if your foreign income is not directly taxable, it must be reported in your German tax return, and it will usually impact your German tax rate (progression effect).

If you are planning to move to or from Germany mid-year, professional tax planning can significantly reduce tax burdens for expats.

Tax Consequences of Becoming a German Tax Resident

Once you are a tax resident in Germany, you are required to report your worldwide income, including:

  • Foreign bank interest, dividends, and investment income
  • Foreign rental income
  • Foreign pensions and retirement payments
  • Foreign earned wages

Key Takeaways

  • German tax residency does not exclusively depend on the 183-day rule
  • Tax residency can be triggered immediately by renting an apartment in Germany
  • You can be tax resident in two countries at the same time
  • Tax treaties reduce double taxation but do not eliminate the requirement to file a tax declaration in Germany
  • Residency often starts earlier than expats expect
