U.S. Expat Taxes in Germany — What Americans Need to Know
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
U.S. expat taxes in Germany combine two systems that overlap almost completely: Germany taxes residents on worldwide income at rates higher than the U.S. for most earners, and the U.S. taxes citizens wherever they live. A treaty and a totalization agreement connect them. Done right, an American in Germany usually owes the U.S. nothing — but files a great deal.

Which tool prevents double tax in Germany?
Usually the foreign tax credit. German income tax, plus the solidarity surcharge and church tax where applicable, typically exceeds the U.S. tax on the same income, so Form 1116 wipes out the U.S. liability and leaves surplus credits to carry forward. The foreign earned income exclusion also works but caps out at the annual limit and forfeits credits on the excluded income; many Americans in Germany come out ahead with the credit alone, especially families who want the refundable child tax credit or IRA eligibility.
How do the treaty and totalization agreement help?
The U.S.–Germany income tax treaty settles pensions, Social Security, and investment withholding, and its relief article is what makes the credits line up. The totalization agreement assigns Social Security coverage to one country — a German-employed American pays into the German system and is exempt from U.S. self-employment or FICA tax; an American sent to Germany temporarily by a U.S. employer can stay U.S.-covered for a period with a certificate of coverage. Self-employed Americans resident in Germany generally pay German contributions and attach proof instead of Schedule SE.
How are German pensions treated on a U.S. return?
The treaty gives German statutory pension payments favorable treatment and protects qualifying employer plans, but Germany's popular personal products — Riester and Rürup contracts, and company pension schemes funded through insurance — don't map neatly onto U.S. categories. Some are treated as foreign pensions with deferral; some are insurance contracts or trusts with annual reporting. Each contract type needs to be identified before assuming deferral, and most are reportable on the FBAR and Form 8938 regardless.
What about German investment funds?
German mutual funds and ETFs — including the ETF savings plans that German brokers promote — are passive foreign investment companies under U.S. rules, with punitive tax on sale and annual Form 8621 reporting. Germany's own fund taxation regime, which levies an annual advance lump sum, doesn't change the U.S. treatment. Americans in Germany typically invest through U.S.-domiciled funds at a U.S. broker, after checking how Germany taxes those.
I own a GmbH or UG. What does the U.S. require?
Form 5471 every year, and the controlled-foreign-corporation rules, which can tax the company's income to you currently even if it's left in the company. German corporate tax paid is creditable against that inclusion. For a one-person company, the check-the-box election to treat it as a disregarded entity often simplifies the U.S. side, at the cost of self-employment tax — unless the totalization agreement covers you, which in Germany it usually does.
Where do U.S.–Germany files go wrong?
- Claiming the exclusion by default when the credit would have been better.
- German tax paid in the wrong U.S. year because the German assessment arrived late — the accrued method on Form 1116 fixes it.
- Pension contracts assumed deferred without checking the type.
- ETF savings plans held for years without Form 8621.
- Capital gains on German shares credited against the wrong basket.
Frequently asked questions
Do I pay U.S. Social Security tax while employed in Germany?
No. Under the totalization agreement, a locally employed American pays German contributions only.
Is my German Riester pension tax-deferred in the U.S.?
Not automatically. Treatment depends on how the specific contract is classified; many are reportable and some produce current income.
How are U.S. retirement accounts taxed in Germany?
The treaty's pension article generally lets Germany tax withdrawals from U.S. plans while respecting deferral during accumulation; Roth treatment is less clear and worth confirming.
Does the German church tax count as a creditable foreign tax?
It is generally treated as an income tax for credit purposes, since it is computed on income tax liability.
