We do not follow trends.
We go ahead. We are forward thinkers.
Opportunity advice since 1923.

Our history testifies: it is the small moments that write great history. With our company comes the competence and experience of over a century of successful consulting. Our origins can be traced back to Mr. Albert Haussmann, who started his own business as a book auditor in Stuttgart as early as 1923 and became one of the first auditors in Germany in 1932. Mr. Haussmann's company grew in the following years and new employees joined the firm, including Mr. Welz and Mr. Seeger, who later became partners. The partnership also gave birth to the firm name HWS - an abbreviation of the first letters of the surnames of the three partners Haussmann, Welz and Seeger.

Since then, we have grown together as HWS, achieved a great deal and are pleased to serve clients of all industries, sizes and legal forms. To this day, our focus is on providing personal and qualified advice to our clients - our executives and over six hundred and fifty employees work every day to think in your best interests and solve problems together with you.


The people in front of the numbers

Always delightful: confirmation of our services.

Of course, we do not work for prizes and awards. The satisfaction of our clients is our top priority. Nevertheless, we are happy when our work and the performance of our employees not only convince our clients but as well as being recognized as tax leaders. This makes us proud and confirms that we have the right team with the right attitude.
