International Business Lawyers in Germany

Full service legal and tax consultation

WINHELLER Attorneys at Law & Tax Advisors provide comprehensive legal and tax services for German and international businesses and nonprofits and charitable organizations. We provide our German and international corporate clients with full-service support for everything from transactional matters (e.g. licensing agreements, employment contracts and visa applications) to dispute resolution and litigation support before all German courts.

International practice

As a German-based law firm, we regularly assist German clients who are expanding their business activities outside of Germany. However, about half of our clients reside and do business outside of Germany, with most of our international clients located in other European countries, the U.S., Russia and the People's Republic of China.

We assist our international clients, including executives and entrepreneurs, with all aspects of German and EU market entry, including 

Tax, Accounting and Payroll

Our services to international companies, executives and entrepreneurs are not limited to legal matters: we also provide ongoing tax, accounting and payroll services. By having one German-contact who can handle all of their financial and legal matters, our clients save time and money.

Foreign law desks

One of the key reasons that our international clients rely on and trust our firm is that we speak our clients’ languages and know their culture. For each of our French speaking, Russian speaking and English speaking clients, we have one or more designated staff members who are fluent in the target language and know the culture.

Irina Winheller and Svetlana Tammer are responsible for our Russian Desk. For Mandarin-speaking clients we have freelance consultants who are fluent in Mandarin.

Key services to international clients

International business law requires international partners

WINHELLER cooperates with external expert partner firms located throughout the world. As a result, we are able to ensure that our German and international clients have the best possible legal and tax advice on all international legal issues that may arise. Our firm is a proud member of The International Society of Primerus Law Firms, a highly selective alliance of medium-sized and partner managed law firms from all over the world. As a member of Primerus, we are able to provide legal and tax advice in international business law and to enforce our clients’ claims just as well, if not better, than firms which maintain hundreds of offices and employ thousands of consultants worldwide.
