The Trewitax story

Trewitax is selected by the magazine BILANZ as one of the 100 TOP Tax Experts & Fiduciaries 2021. We are pleased about this award in the category Generalists!

Als eine der ersten Steuerberatungsgesellschaften in Deutschland wurde die Trewitax GmbH aus Singen im März 2019 von DATEV mit dem Zertifikat «Digitale Kanzlei 2019» ausgezeichnet.

Im Januar 2023 folgte nun das Jubiläum! 5 Jahr «Digitale Kanzlei»

Diesen Erfolg dürfen nur wenige Kanzleien in Deutschland feiern. 

Mit der Gründung der Trewitax Freiburg GmbH im April 2023, erweitert die Trewitax-Allianz ihren Beratungsraum im Badischen in Richtung Westen. 

Die Trewitax GmbH in Deutschland erweitert sich im Januar 2022 um eine weiter Niederlassung im schönen Konstanz direkt am See-Rhein. 

In March 2019, Trewitax GmbH from Singen was one of the first tax consulting firms in Germany to be awarded the "Digital Law Firm 2019" certificate by DATEV. In January 2022, the award was finally presented for the fourth time in a row. In DATEV's Germany-wide industry comparison, the Singen location was thus certified as having an excellent digitalization rate and digitalization quality.

The law firm Holzeisen Reich Oberthaler Putz from South Tyrol's capital Bolzano, Italy, joins the Trewitax alliance.

Personal esteem and professional competence are also the basis for the expansion of the Trewitax family: The law firm SPT Dornbirn from Bregenz - until 2015 law firm Schrottenbaum und Partner - comes under the Trewitax umbrella.

The Trewitax companies join the international alliance Geneva Group International (GGI). As a member of one of the world's largest networks of independent auditors, tax advisors and lawyers, they can thus draw on an even broader international expertise and competently clarify special cases that arise for globally active clients.

Allianz co-founder Bruno Faoro opens another location in Zurich. From now on, the team in Kreuzlingen trades as Trewitax Kreuzlingen AG and the Zurich location as Trewitax Zürich AG.

Trewitax grows and overcomes borders: Stefan Zürcher, co-founder of Trewitax GmbH in Kreuzlingen, and Martin Klump, tax consultant and auditor from the German side of Lake Constance, get to know each other through a mutual client and from then on appreciate the cooperation. The foundation of Trewitax Wirtschaftsprüfungs GmbH in Singen follows.

A common client brings Trewitax from Kreuzlingen together with Franz Broger and Hermann Rothauer of the RCR Group from St. Gallen. The trusting cooperation turns into a partnership: Trewitax St. Gallen AG is founded.

Bruno Faoro and Stefan Zürcher work together in Kreuzlingen in an office partnership. In order to serve joint clients from a single source, they founded Trewitax GmbH.
