The average time a human needs
to fall asleep, in minutes

— TRUST to the point.

To keep you from having sleepless nights, we analyze your financial, fiscal and even your personal situation to develop a sound strategy for you and your company. Our goal is your satisfaction. Helping us reach this goal is our long-term and future-oriented method of operating.


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

— About us.

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.

— We are TRUST.

Kurt Wallnberger as CEO, supported by a team of outstanding colleagues.


Demand of ourselves: quality
measured in numbers

— Quotes.

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

“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

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

Günther Roth & Reini Gnettner, Feuer Werbeagentur GmbH

Even for us it is impossible to calculate the exact number of reasons why you should become a client of TRUST. But at least we can list the most important ones here: We see ourselves as a universal service provider for your business figures. To this end, we develop a strategy for each client:in and also for you.

We are specialized in planning and controlling in the field of accounting, taxes and organization for SMEs. In addition to SMEs, we also serve international clients, perform audits, serve and represent private foundations and advise landlords and real estate developers. We are goal-oriented, organized and our performance is far above average. And last but not least: we work 100% digitally - but can still handle paper, should the need arise.

But now we've really talked enough about us. Let's talk about you and how we can help you. The best way to do this is to make an appointment online using this form or directly by calling +43 218 66 24.

— The beauty of numbers.

As tax accountants, we inevitably deal with numbers a lot. For many people, this may seem like a boring idea - but numbers are definitely exciting and entertaining, as you can also see on this website. Another example: 0815 - a number combination you will never encounter with us.
