Personal Cross-Border Tax Advice Without the Hand-Offs

One primary adviser manages your entire cross-border tax case, personally assesses how German, Swiss and U.S. tax rules interact with the relevant tax treaties, and develops the connected tax positions as one overall case.

From the initial tax analysis and filings through assessments, foreign tax credits, tax authority questions and required amendments, the same adviser remains involved in your cross-border matter.

Why our cross-border model is different
One Primary Adviser One person understands and remains responsible for the overall cross-border case.
One Integrated Analysis Multiple tax systems and treaty rules are assessed together.
One Data Collection Information is collected once and used across the relevant filings.
Tax Authority Representation The same adviser can remain involved when authorities raise questions later.

What Makes TaxRep Different

One adviser. One substantive view across the relevant tax systems.

International tax matters often involve more than one country at the same time. Residence, employment, businesses, ownership interests, investments, real estate or retirement arrangements may create very different tax consequences in Germany, Switzerland and the United States.

The most difficult questions frequently arise not within one tax system, but at the point where two systems interact.

Your case is therefore not simply passed between separate country advisers. Your primary adviser personally assesses the interaction of the relevant tax systems and treaty rules and develops the cross-border tax position with all affected jurisdictions in mind.

More Than Coordination Having one point of contact does not by itself solve the substantive problem of a cross-border tax case. What matters is whether that adviser personally understands the interaction between the tax systems or merely coordinates separate country specialists.

One Cross-Border Tax Position

The tax positions are developed together before either return is filed.

A German, Swiss or U.S. tax return may be technically correct when viewed on its own and still produce a poor cross-border result if the underlying positions were developed independently.

Tax residency, income sourcing, withholding taxes, treaty rules, foreign tax credits, ownership interests, retirement arrangements and transaction timing can affect more than one jurisdiction at once.

We therefore develop the connected tax positions together before filing and then implement them consistently across the relevant returns.

One Case from Start to Finish

Our involvement does not end when the tax returns are filed.

Cross-border tax matters often continue after filing. Tax assessments, withholding tax refunds, foreign tax credits and authority questions in one country may require additional action in another.

Assessments and Foreign Tax Credits

Foreign assessments, withholding taxes and foreign tax credits are followed through with their impact on the other jurisdiction in mind.

Tax Authority Questions

The adviser who developed the original cross-border position can personally continue the case when the relevant tax authorities request information or clarification.

Amendments and Corrections

If a tax position changes in one country, any required amendments, supplemental filings or adjustments in another jurisdiction are considered as part of the same case.

Personal Continuity

Your matter is not handed off to a new local adviser once the original returns have been filed.

About TaxRep

Personal Cross-Border Tax Advice for Germany, Switzerland and the United States

TaxRep is designed for clients whose tax affairs do not stop at a national border. Our focus is therefore not on passing the matter between separate country advisers, but on maintaining one substantive view of the overall cross-border case.

National tax rules, treaty provisions, filings, deadlines and later follow-up matters are considered in the context of the entire case.

The legal and professional entity responsible for a particular service depends on the jurisdiction and the engagement. We explain that organizational structure separately rather than making it the basis of the client experience.

Whether you need a German tax return, have Swiss tax exposure, remain subject to U.S. tax, are relocating internationally or have filing obligations in more than one country, we first look at the overall tax position and then determine the required filings, deadlines and follow-up steps.
