FAQ

Frequently Asked Questions

Answers to the questions we hear most often from new clients.

Can MST represent me in Swiss court proceedings?
Yes. Our licensed attorneys are authorised to appear before all Swiss cantonal and federal courts, including the Swiss Federal Supreme Court. We handle civil, commercial, administrative and appellate proceedings.
How do I register a company in Switzerland?
We manage the entire company formation process — from selecting the appropriate legal structure (GmbH, AG, Branch, etc.) to drafting articles of incorporation, registering with the commercial register and obtaining all required licenses. Most formations are completed within 5–10 business days.
What tax services do you provide for individuals and businesses?
Our tax team handles Swiss federal and cantonal tax returns, VAT registration and compliance, international tax planning, withholding tax reclaims, OECD BEPS compliance, and representation before the Federal Tax Administration (FTA) in audits or disputes.
Do you serve international clients based outside Switzerland?
Absolutely. A significant portion of our clients are international businesses and high-net-worth individuals who require Swiss-based legal, tax or financial expertise. We work remotely and in multiple languages, and can arrange secure video consultations for clients in any time zone.
Is my initial consultation really free and confidential?
Yes, completely. Your first consultation carries no fee and no obligation. Everything you share is protected by Swiss attorney-client privilege from the moment you contact us. We will only proceed to a formal engagement if you explicitly agree to our terms of engagement.
