Germany–U.S. Cross-Border Tax
Germany–U.S. tax advice from one source
One responsible cross-border professional manages your entire Germany–U.S. tax matter, analyzes the interaction between German and U.S. tax law and the applicable tax treaty, and develops the connected tax positions together.
The same contact coordinates German and U.S. tax returns, international reporting obligations, Foreign Tax Credits, filing deadlines and subsequent proceedings and can also represent you personally before the German tax authorities and the IRS.
Why our cross-border model makes a differenceOne situation – two tax systems
The most important questions arise where German and U.S. tax law interact
The United States does not base personal tax obligations solely on residence. U.S. citizenship and Green Card status can also result in continuing U.S. federal tax and reporting obligations even for individuals permanently resident in Germany.
At the same time, German rules for investments, businesses, retirement arrangements, real estate and capital gains can differ significantly from their U.S. treatment.
TaxRep therefore analyzes German tax law, U.S. tax law, the Germany–U.S. tax treaty, Foreign Tax Credits and international U.S. reporting as parts of the same cross-border tax situation.
What makes TaxRep different
One person understands both sides of your Germany–U.S. tax situation
Having one central contact is not enough if the actual tax analysis is still performed by separate country advisers. What matters is that the same professional can analyze the German treatment, the U.S. treatment and the treaty consequences directly.
Germany, the United States and the treaty are analyzed as one connected tax matter rather than sequentially.
Connected German and U.S. positions are developed together before the relevant returns are filed.
Tax returns, FBAR, FATCA, Foreign Tax Credits and deadlines are handled as parts of the same compliance process.
The same professional can remain involved if the Finanzamt or IRS raises questions after filing.

Two systems – one tax position
German and U.S. tax positions are developed together before filing
Tax returns should not be prepared independently
Income, withholding taxes, Foreign Tax Credits, treaty positions and reporting obligations are allocated consistently between both countries before the returns are filed.
Entities must be analyzed in both tax systems
For LLCs, corporations and German entities, we consider entity classification, German tax characterization, shareholder reporting, permanent establishments, withholding taxes and ongoing compliance together.
One continuous process
From initial analysis through assessments and tax-authority questions
Integrated intake
We gather citizenship, residences, travel periods, income, assets, companies, bank accounts, investments and prior tax filings once for the entire cross-border matter.
Cross-border analysis
German tax liability, U.S. tax, treaty rules, Foreign Tax Credits, international reporting and relevant interactions are analyzed together.
Filing and deadlines
German and U.S. tax returns, information returns and supporting documentation are coordinated technically and chronologically.
Follow-up and representation
Tax assessments, Foreign Tax Credits, questions from the Finanzamt or IRS, supplemental filings and amendments remain part of the same cross-border matter.
Personal tax-authority representation
The same professional remains involved if questions arise later
In Germany–U.S. cases, follow-up issues often arise only after filing. The German Finanzamt may request a U.S. tax return, assessment or additional documentation. The IRS may request information concerning German income, accounts, companies or investments.
A later tax assessment in one country can also require a revision of the Foreign Tax Credit or an amendment of the return filed in the other country.
The professional who developed the original Germany–U.S. tax position already understands these interactions and can therefore continue handling the matter during subsequent tax-authority proceedings.

Germany–U.S. cross-border tax advice
Do U.S. citizens living in Germany still have to file a U.S. tax return?
In general, U.S. citizens remain subject to U.S. federal tax filing obligations even when they live permanently in Germany. Whether U.S. tax is ultimately due depends on income, Foreign Tax Credits, possible exclusions, treaty provisions and the specific facts.
Will I have separate advisers for Germany and the United States?
Your Germany–U.S. matter is handled by one central professional who can analyze the German and U.S. tax treatment directly, including the relevant treaty and foreign-tax-credit issues.
Can TaxRep represent me before the German tax authorities and the IRS?
Depending on the particular proceeding and required authorization, the professional responsible for the cross-border case can also continue the matter personally before the German Finanzamt and the IRS.
When is an FBAR required?
An FBAR may be required when the aggregate maximum value of foreign financial accounts exceeds the applicable reporting threshold during the calendar year. German bank and brokerage accounts can be relevant for this purpose.
Why can German investment funds be problematic for U.S. persons?
Many non-U.S. investment funds can qualify as Passive Foreign Investment Companies (PFICs) for U.S. tax purposes. This can trigger additional forms, complex calculations and unfavorable U.S. tax rules.
How is a U.S. LLC taxed in Germany?
German tax classification does not automatically follow the U.S. classification. It depends on the LLC's legal characteristics and its comparison with German legal forms. The entity should therefore be analyzed from both the German and U.S. perspectives.
Do you also advise on moving from Germany to the United States?
Yes. Relevant issues include the timing of departure, remaining German tax obligations, potential German exit taxation, shareholdings, investments, retirement plans, U.S. residency and tax filings for the transition year.
