FIN
FIN is an independent advisory headquartered in Zug and active across several cantons, with Zurich, Zug, Geneva, Basel, St. Gallen, Aargau, Thurgau, and Schwyz named on its site. It pays particular attention to B and C permit holders and the question many of them face: whether to stay on tax at source or file an ordinary Swiss return, and when a pillar 3a contribution is actually worth it for someone taxed at source. The site is available in English and German.
The advice is product-neutral. FIN does not manage assets or trade day to day, and works on a fee basis agreed in advance, with no long-term contract and one dedicated adviser per client. Beyond the tax-at-source question, the firm helps with all three pillars of the Swiss pension system, vested benefits accounts, retirement decisions such as lump sum versus annuity, property financing and mortgages, investment review, and inheritance and estate planning. It covers self-employed people and sole proprietors as well as employees.
