Karl Egger brings decades of experience in advising complex, high-level mandates within Swiss and international frameworks.
As owner of the boutique advisory firm Egger Treuhand in Stansstad, he primarily advised High Net Worth Individuals, entrepreneurial families, and selected corporates at a strategic level.

His work includes:
- designing international tax structures
applying patent box regimes and IP-based income models - optimizing structures under international tax treaties
- structuring foundations, holdings and participation models
- serving on boards of directors in public and private companies
Prior to his private career, Karl Egger served as one of the youngest authorized officers at Coop, where he was involved in controlling for international operations — shaping his analytical and structured approach.
He holds the Swiss federal qualification as a Certified Expert in Accounting and Controlling, classified at the highest level (NQF/EQF Level 8) .
Within BAMAT, his role is clearly defined:
to design robust, legally sound, and tax-efficient structures for complex investor situations.
A particular focus lies on sensitive topics such as:
- asset protection
- tax residency
- structuring
- and the long-term preservation of Swiss status for international clients
He operates deliberately in the background, as the architect of structure, not a public-facing advisor.
