Your figures are high priority for us



In the numbers we see your potential


It takes experience to develop a good eye for figures and we’ve got it. Honold Treuhand AG was founded in 1949 by Anton Honold. Since then, we have been advising small and medium-sized businesses, private individuals and families, as well as larger groups of companies, as a renowned auditing and fiduciary office.


We see our potential particularly in our highly qualified employees and our experience. Thus, we offer comprehensive advice and support in all financial areas. Due to our broad orientation and the versatile and always up-to-date training of our employees, we can respond to your potential individually.


We recognize your potential in your figures, which benefits you, especially in tax and business consultancy. But also when it comes to auditing and other fiduciary activities you can rely on our experience, reliability and integrity. It is important to us that you always have the same contact person, where possible, for years.


For many years, we have been working closely with our partner company Staubli + Partner, thereby leveraging the synergies of specialists from various specialist areas. As a traditional accounting and consulting company, they complement our activities, in particular in the management of payroll accounting and outsourcing of entire bookkeeping.


Nationally, we have been a member of ExpertSuisse  for decades and are thus well connected and always up to date in our highly dynamic industry.


Internationally, we are associated with the ABACUS worldwide as a representative for Switzerland. This allows us to assist you across the borders as a consultant. We are happy to arrange contacts for specific inquiries to personally known partners.
