Our firm was founded in 2017 to provide Swiss and international competent tax advice. We are committed to delivering high quality and customised tax advisory services for private clients and corporations as well as reliable support for accounting services. Excellence is a dedication we are trying to reach for each of our mandates and every situation. We are your trusted partner for all your Swiss tax services.

We have an extensive international network, particularly in France and Canada, to ensure adequate tax advice for our clients with an international profile.

We are a member of various tax organizations such as the Ordre romand des experts fiscaux (OREF), the Association Suisse des experts fiscaux diplômés (ASEFID), International Fiscal Association (IFA) and EXPERTSuisse. All those memberships are necessary to keep us informed about the evolving regulations and developments in tax, corporate governance, as well as accounting matters.

Our Values

Our Values are the pillars of our firm. They lead our company and our entrepreneurial spirit and serve as the basis for the decisions we make and the actions we take. They define who we are and how we work.

— Integrity

By acting ethically and with integrity we have earned the trust of clients and regulators. Upholding that trust is our most important responsibility.

— Confidentiality

We protect the privacy of our clients and manage mandates with the utmost confidentiality.

— Excellence

We strive to deliver the highest quality services to our clients by listening to their individual and personal needs and providing tailor-made solutions.

We reject preconceived ideas. An individual analysis of the clients’ situation allows us to provide with tailor made solutions which are efficient and meet their needs and expectations. We think out of the box, which allows us a permanent repositioning at the cutting edge of the profession.

Our Activities

— Tax advice for private individuals and corporations

Our team is dedicated to provide individualized solutions related to all Swiss related tax matters. We help in defining the tax strategy for short- and long-term views, by taking into account the ongoing regulatory constraints. We always use a holistic and pragmatic approach to providing our clients the best possible solution at all times.

‘One-stop shop’ for the creation and incorporation of companies

  • We assist our corporate clients in establishing companies, holdings, associations and foundations in Switzerland. Perrin & Co LLC’s know-how will allow to set up businesses in peace, discretion and efficiency.
    Our goal is to add value by providing management support and customized administrative services. Beyond the administrative formalities for setting up a business, we assist in the preparation of the statutes of association as well as all related founding documents. Our broad network and reputation allow us to efficiently accomplish such mandates.
    Switzerland requires companies and foundations to be represented by at least one person resident in Switzerland. Perrin & Co LLC can assist with a nominee director or a member of the board to be a Swiss legal representative. We represent companies in front of various Swiss authorities and we are an experienced and trustworthy partner always protecting the best interests of our clients.
