Germany–United States Cross-Border Tax

Germany–U.S. Tax Advice With One Primary Adviser

One primary adviser manages your entire Germany–U.S. tax case, personally assesses how German and U.S. tax rules interact with the applicable tax treaty, and develops the connected tax positions as one overall cross-border matter.

The same adviser remains involved across German and U.S. tax returns, international reporting obligations, foreign tax credits, deadlines and later follow-up and can also represent you personally before the relevant German tax authorities and the IRS.

Why our cross-border model is different

One Case – Two Tax Systems

The key issues arise where German and U.S. tax rules interact

The United States does not base individual taxation solely on residence. U.S. citizenship and Green Card status can create ongoing U.S. tax filing and reporting obligations even for individuals who permanently live in Germany.

At the same time, German rules for investments, business entities, retirement arrangements, real estate and capital gains can differ significantly from their U.S. tax treatment.

German tax law, U.S. tax law, the Germany–U.S. tax treaty, foreign tax credits and international U.S. reporting obligations therefore need to be considered as parts of the same cross-border case.

More than coordinated advice Your matter is not simply passed between a German adviser and a U.S. adviser. Your primary adviser personally assesses the interaction between both systems and develops the connected tax positions together.

What Makes TaxRep Different

One adviser understands both sides of the Germany–U.S. tax case

A single point of contact alone does not solve the substantive problem if the tax analysis is still performed independently by separate country advisers. What matters is whether the same adviser can personally assess the German treatment, the U.S. treatment and the treaty consequences.

One Integrated Analysis

German tax law, U.S. tax law and treaty rules are analyzed as one connected cross-border matter.

One Coordinated Tax Position

The connected German and U.S. tax positions are developed together before the relevant returns are filed.

One Continuous Compliance Process

Tax returns, FBAR, FATCA, foreign tax credits and deadlines are managed as one connected process.

Personal Authority Representation

The same adviser can remain involved when German tax authorities or the IRS raise questions later.

Two Systems – One Tax Position

German and U.S. tax positions are developed together before filing

Individuals

Do not prepare the two returns independently

Income, withholding taxes, foreign tax credits, treaty positions and reporting obligations are allocated consistently across both countries before the relevant returns are filed.

Businesses

Classify entities consistently across both systems

For LLCs, corporations and German entities, we consider U.S. entity classification, German tax classification, ownership reporting, permanent establishments, withholding taxes and ongoing compliance together.

One Continuous Process

From the initial facts through assessments and tax authority questions

One Intake

We collect citizenship, residence, travel days, income, assets, entities, accounts, investments and prior filings once for the overall cross-border case.

Cross-Border Analysis

German tax liability, U.S. tax, treaty rules, foreign tax credits and international reporting obligations are analyzed together.

Filing and Deadlines

German and U.S. tax returns, information filings and supporting documentation are aligned substantively and across the relevant filing deadlines.

Follow-Up and Representation

Tax assessments, foreign tax credits, questions from German tax authorities or the IRS, supplemental filings and required amendments remain part of the same case.

Personal Tax Authority Representation

The same adviser remains involved when tax authorities raise questions

Germany–U.S. tax matters frequently continue after the original filings have been submitted. A German tax office may request a U.S. assessment or additional supporting documentation. The IRS may ask for information regarding German income, accounts, entities or investments.

A later tax assessment in one country can also change the foreign tax credit or require an amendment in the other country.

Because the adviser who developed the original Germany–U.S. tax position already understands these interactions, the same adviser can continue the matter personally when later authority questions arise.

Frequently Asked Questions

Germany–U.S. Cross-Border Tax Advice

Do U.S. citizens living in Germany still have to file a U.S. tax return?

U.S. citizens generally remain subject to U.S. federal income tax filing requirements even when they permanently live in Germany. Whether U.S. tax is ultimately payable depends on income, foreign tax credits, available exclusions, treaty provisions and the individual circumstances.

Will I have different advisers for Germany and the United States?

Your Germany–U.S. case is substantively managed by one primary adviser who personally assesses the German tax treatment, the U.S. tax treatment and the relevant treaty and foreign tax credit issues.

Can TaxRep represent me before German tax authorities and the IRS?

Depending on the specific procedure and required authorization, the primary adviser can also continue the matter personally before the relevant German tax authorities and the IRS. This helps preserve the original cross-border tax position throughout the follow-up process.

When is an FBAR required?

An FBAR may be required when the aggregate maximum value of foreign financial accounts exceeds the applicable threshold during the calendar year. German bank accounts and brokerage accounts may be included for this purpose.

Why can German investment funds be problematic for U.S. persons?

Many non-U.S. investment funds can be treated as Passive Foreign Investment Companies, or PFICs, for U.S. tax purposes. This may result in additional reporting, complex calculations and unfavorable U.S. tax rules.

How is a U.S. LLC taxed in Germany?

German tax treatment does not automatically follow the U.S. classification. The German classification depends in particular on the legal characteristics of the LLC and its comparability with German legal forms. The entity should therefore be analyzed under both German and U.S. tax rules.

Do you also advise on moving from Germany to the United States?

Yes. Relevant issues can include the timing of the move, remaining German tax exposure, German exit taxation, ownership interests, investments, retirement assets, U.S. residency and the tax filings required for the transition year.
