Independent Fiduciary · Canton Zug · Since 2010
What we do
From day-to-day bookkeeping to international holding structures — our twelve specialists handle it all.
Monthly close, Swiss GAAP FER, OR-compliant statutory accounts and consolidated group reporting. We integrate with your ERP or manage the books entirely in-house.
Federal and cantonal returns, VAT compliance, withholding tax reclaims. Specialist knowledge of Canton Zug's holding and mixed company regimes — and Pillar Two readiness.
End-to-end payroll, social insurance, ELM reporting and expense management across all Swiss cantons. Fully confidential, also for family offices and private clients.
Statutory and voluntary audits by RAB-registered auditors. Ordinary and limited audits for Swiss companies of all sizes. Independent and thorough — always on schedule.
GmbH and AG incorporation, registered address, domicile and ongoing corporate secretarial. Director and nominee services where required. Canton Zug expertise from day one.
VAT registration, quarterly and annual filing, input tax recovery and representation before the Federal Tax Administration. Covering domestic and cross-border transactions.
Swiss law requires at least one authorised signatory domiciled in Switzerland. We provide a licensed fiduciary director registered in the Zug Handelsregister from CHF 390/month.
Official domicile address at Stockerstrasse 21, 6300 Zug — fully registerable in the Handelsregister and recognised by the Steueramt. Mail handling and virtual office available.
Swiss banks reject unprepared applications. We prepare your full KYC dossier, match your structure to the right bank, and manage follow-up until your account is active.
"In Zug, we don't file your taxes.
We build the structure around them."
Mueller Stöckli Treuhand AG · Zug, Switzerland
About the firm
Mueller Stöckli Treuhand AG was founded in 2010 with a single purpose: to give entrepreneurs, private individuals and international holding structures access to the same quality of fiduciary advice previously reserved for large corporates.
Our twelve specialists hold qualifications from EXPERTsuisse and the Swiss Institute of Certified Accountants. We are RAB-registered auditors and authorised tax representatives before the Swiss Federal Tax Administration.
Based at Stockerstrasse 21 in Zug, we work across all Swiss cantons and maintain close relationships with leading law firms, notaries and banking institutions in the canton.
Get in touch
We respond within one business day. Initial consultations are complimentary and confidential.
A Swiss fiduciary (Treuhänder) handles accounting, bookkeeping, tax returns, statutory audit, payroll, VAT compliance, company formation, and compliance obligations for businesses and private clients. EXPERTsuisse-certified fiduciaries, like Mueller Stöckli Treuhand AG, also provide tax advisory and statutory audit under RAB licence.
Zug offers Switzerland's lowest effective corporate tax rate — approximately 11.85% combined (federal, cantonal, municipal). The canton has a stable regulatory environment, a large international business community, and straightforward company formation procedures. GmbH formation takes 2–5 business days.
We offer three options: a Starter package billed hourly at CHF 150/hour for low-volume clients, a fixed CHF 249/month SME package for predictable workloads, and Enterprise mandates priced on request. See our pricing page for full details.
