On 1 July 2026, we celebrate a special milestone: ten years of operating under the name ACCONSIS. Our roots, however, go back much further. For more than 60 years, we have been advising clients on tax, legal, business and entrepreneurial matters.
Consistency in a time of change
Over the past decades, the world has changed significantly. Businesses have grown, markets have become increasingly complex, regulatory requirements have expanded, digitalisation has transformed processes, and personal and business-related matters are more interconnected than ever before.
Over the last ten years, ACCONSIS has also continued to evolve. Our group has grown steadily, our range of services has expanded continuously, and today around 170 colleagues work together to support our clients across a wide variety of challenges.
What has remained unchanged is our conviction that great advice begins with understanding. We will continue to listen carefully, recognise the bigger picture and provide clear guidance wherever important decisions need to be made and the next steps defined. With experience, expertise and a genuine commitment to supporting our clients personally and reliably throughout both their personal and business journeys.
„For more than six decades, we have supported individuals, families, entrepreneurs and businesses in making important decisions. Their trust has always been the foundation of our success. This anniversary is therefore, above all, an opportunity to thank all our clients, employees and partners who have accompanied us on this journey and will continue to shape our future together with us.“
Dr Christopher Arendt, Managing Director and Member of the Executive Board, ACCONSIS
Looking to the future with confidence
We see this anniversary not only as an opportunity to reflect on our history, but also as confirmation that we are on the right path. Many of our client relationships have lasted for years—some even for decades. At the same time, we are firmly focused on the future. Our goal is to continue developing our advisory services, further strengthen our expertise and sustainably grow our group.
In an increasingly complex world, we see our role as making complexity understandable, identifying opportunities and helping our clients make the right decisions for the future. This commitment has shaped our work for many years and is reflected in our guiding principle today: We help you navigate tax, legal and business challenges.
For us, this means taking responsibility, offering forward-looking advice and standing alongside our clients as a trusted and dependable partner.
We look forward to continuing to support our clients in meeting their tax, legal and business challenges in the years ahead—and to shaping the future together.
Thank you for your trust.
