About us


The Answer to the Ultimate Question of Life, the Universe, and Everything according to “The Hitchhiker’s Guide to the Galaxy.”

For economics questions, there is no universal answer. That is why at the heart of our work are both the analysis of your current situation and the creation of a long-term economic and fiscal strategy. It is impossible to work together towards a happy ending without knowing the story behind the numbers. To ensure everything adds up, we not only rely on decades of experience, but also on our team of talented individuals.



demand of ourselves: quality
measured in numbers

To find out if we truly meet this demand, we asked our clients. These are their answers.

“We have been working with Kurt Wallnberger and his team for 20 years. It’s a great feeling to have such a dedicated and professional partner at your side.”

ibis acam Bildung GmbH, CEO Raphel Montibeller

“In Kurt we TRUST. We’ve been saying that for a while now.”

Günther Roth & Reini Gnettner, Feuer Werbeagentur GmbH

“Kurt Wallnberger is a tax advisor and businessman. That provides him with a unique perspective. As his client, you can focus fully on business matters and let him take care of all the accounting and fiscal matters. Most tax advisors do not think like a businessman, let alone understand how a business operates. Kurt Wallnberger does more than just crunch numbers, he understands how to create value. He is a longtime partner and companion.”

Thomas Plötzeneder, Gehrer Plötzeneder DDWS GmbH
