Duss Treuhand

With Duss Treuhand GmbH, you are partnering with a well-established fiduciary company based in the city of Zug. We look after over 200 SMEs and private individuals in Switzerland and abroad, most of whom have been with us for years or even decades. Our clients have very high standards and expect us to provide optimum solutions for their tasks and problems – expectations that we are happy to fulfil: with all-round dedication and personal services that are precisely tailored to the individual needs of our clientele. When will you begin partnering with us?

Not only since yesterday...


Duss Treuhand GmbH was set up by Anton Duss and Irma Duss in February 1990. Anton Duss has more than 40 years of experience as a fiduciary in Zug.


We were able to celebrate our first big 10 year anniversary at the turn of the millennium and the company meanwhile has grown to over 6 staff.


In 2010 we celebrated our 20 year anniversary. We have stayed true to our philosophy throughout: Committed to everything. But not every possible thing.


In July 2015, we moved to our new offices in the lovely Schutzengel quarter and celebrated our 25 year anniversary.


30th anniversary in the year of Corona - unfortunately without a celebration. We are proud to be able to count on a great and loyal clientele, especially in these challenging times. Thank you very much.
