German Tax Perspective · U.S. Retirement Benefit
U.S. Social Security While Resident in Germany
If you are tax-resident in Germany and receive U.S. Social Security, the benefit must be classified separately for German tax purposes. The Germany–U.S. tax treaty generally assigns social-security benefits to the residence state. If you are treaty-resident in Germany, Germany therefore generally has the taxing right. The next step is to determine how the U.S. benefit is treated under German tax law.
Germany–U.S. Tax Treaty
U.S. Social Security Is Generally Taxable Only in Germany if the Recipient Is Resident in Germany
Article 18(5) of the Germany–U.S. tax treaty contains a special rule for social-security benefits. Benefits paid by one contracting state to a resident of the other contracting state are generally taxable only in the residence state.
If the recipient is treaty-resident in Germany, Germany therefore generally has the taxing right over U.S. Social Security.
Special Treaty Rule
Germany Treats the U.S. Benefit as if It Were a Benefit Under Its Own Social-Security System
Article 18(5) does more than determine which country may tax the benefit. It also provides that the residence state treats the foreign social-security payment as though it were a benefit under its own social-security legislation.
For a recipient resident in Germany, this means that U.S. Social Security is generally brought into the German system of pension taxation for German tax purposes.
- determine treaty residence in Germany
- classify the payment as U.S. Social Security
- apply Article 18(5)
- taxing right generally in Germany
- German classification under the EStG
- do not copy the U.S. tax calculation mechanically
German Tax Law
A Separate German Tax Classification Is Required for the German Tax Return
Foreign pension and social-security benefits are classified for German tax purposes under German law. The U.S. label or U.S. tax treatment is not by itself controlling.
German pension taxation under Section 22 EStG can apply to benefits from foreign pension institutions. The German tax treatment therefore requires its own calculation based on German rules.
German Pension Taxation
The Taxable Percentage Is Generally Determined Under German Pension Rules
If U.S. Social Security is treated under German law as a basic pension-type benefit, the taxable portion is generally determined by the German percentage applicable to the year in which the pension began.
The permanently tax-exempt portion is determined under German rules. For a pension beginning in 2026, the statutory taxable percentage is generally 84%. If benefits started earlier, the percentage for the relevant start year applies.
Determine the Pension Start Year
The year in which recurring pension payments began is generally relevant for the taxable percentage.
Convert to EUR
Amounts paid in U.S. dollars must be converted into euros for the German tax return.
German Pension Allowance
The tax-exempt portion is determined under German rules and is not taken from the U.S. tax return.
Other German Income
The taxable portion of the pension is included in the German income tax assessment together with other taxable income.
Correct Classification
U.S. Social Security Must Be Distinguished From Other U.S. Retirement Arrangements
U.S. Social Security
Social-security benefit subject to the special treaty rule in Article 18(5) and German classification as a foreign social-security pension.
401(k)
Employer-related U.S. pension plan. The German tax treatment follows different rules and requires a separate analysis.
Traditional IRA
Individual Retirement Arrangement with its own German classification and treaty analysis.
Roth IRA
Special U.S. retirement arrangement for which contribution history and plan qualification can be important for German tax purposes.
Moving to Germany
If You Move During the Year, the Start of German Tax Residence Must Be Determined Carefully
If the pensioner moves to Germany during the calendar year, it is necessary to determine when unlimited German tax liability and German treaty residence begin.
Periods before and after the move can therefore be subject to different tax rules. Payment dates, establishment of residence and treaty residence should be documented carefully.
U.S. Tax Perspective

Common Errors
What Is Often Done Incorrectly With U.S. Social Security in Germany
Using the U.S. Tax Calculation
The portion taxable in the U.S. is not automatically the portion taxable in Germany.
Treating Social Security Like a 401(k)
The two benefits are subject to different treaty and German classification rules.
Failing to Document the Pension Start Year
The year the pension began can be important for the German taxable percentage.
Ignoring the Move Year
German tax liability may begin only during the calendar year.
