What Trewitax stands for

Trewitax stands for fiduciary services, auditing and tax advisory. Our alliance of legally self-relying and commercially independent companies is united by the know-how, quality and motivation. Whether in Switzerland, in Germany, in Austria or South Tyrol– Trewitax provides advice in a sustainable manner and on an equal footing. 

What distinguishes us: your advisor accompanies and supports you personally and with a great commitment. 

The Trewitax alliance, with its 100 collaborators is large enough to advise you comprehensively and expertly. At the same time, we are small enough to be flexible and to adapt to your personal needs.

We work with great dedication and offer custom made solutions, connecting our cross-border know-how. This makes us the first independent tax advisory and auditing alliance in the D-A-CH-S region.
