What ISIS) - Institut für Schweizerisches und Internationales Steuerrecht does

ISIS) - Institut für Schweizerisches und Internationales Steuerrecht is an independent, non-profit association (Verein) founded in Switzerland in 2001 that delivers scientifically grounded and practice-oriented continuing education in Swiss and international tax law. Its core products are professional seminars (in-person, hybrid, and online webinars including Tax Talks), the zsis) online tax law publication portal, and the SIST academic study programs delivered in partnership with Kalaidos Law School. The institute maintains a membership model with approximately 150 individual and 30 corporate members drawn from the Swiss tax community, including partners from major firms (Deloitte, Walder Wyss, Altenburger legal + tax), university professors, and senior tax administration officials.

The business model is a hybrid of member subscriptions and per-event fees. Members receive discounts on seminars (CHF 100 for 1-day, CHF 170 for 2-day) and webinars (CHF 20), while non-members pay CHF 190 per webinar. The pricing varies by event type and membership status, with the institute also operating a wholly-owned subsidiary (Seminare ISIS AG) for seminar organization and event management. Distribution runs through ISIS's own website (isistax.ch), integrated with Livingroom Events for registration and dashboard access, plus physical venues in Zurich-Oerlikon, Bad Ragaz, Brunnen, and Lausanne for Romandie-language seminars.

The institute runs a multi-channel marketing approach including website content, email newsletters (10 issues per year), a LinkedIn company page, and content through zsis.ch. Its value proposition rests on independence, scientific rigor, and recognized certificates of continuing education. The leadership transitioned in 2026 with Prof. Dr. Luzius Cavelti succeeding long-serving President Peter Mäusli-Allenspach. The institute is not a venture-backed business; it is a member-funded association with no disclosed revenue, parent company, or external funding rounds.

Regional players

• SAFFA Swiss Association of Financial Analysts: Swiss professional association for financial analysts and wealth advisors with overlapping interest in tax-relevant continuing education. Comparable as a Swiss CPE-focused membership organization serving finance-adjacent professionals.

Broad incumbents

• International Fiscal Association (IFA): Global scientific and professional organization for cross-border tax practitioners, with national branches across Europe. Comparable to ISIS as an international tax professional-education body, but operating at much larger global scale.
• International Bar Association (IBA) — Tax Section: Global organization of legal practitioners with a dedicated tax committee offering conferences and CPE. Comparable to ISIS in delivering international tax-law continuing education, though at much larger global scale.

Direct peers

• Schweizerischer Anwaltsverband (SAV / Swiss Bar Association): National professional body for Swiss lawyers that organizes legal continuing education and member services. Comparable to ISIS as a Swiss legal-professional membership and education organization, though with broader mandate beyond tax law.
• EXPERTsuisse: Swiss umbrella association for fiduciary, audit, and tax experts that runs its own certification and continuing education programs. Directly comparable to ISIS as a peer professional-body providing CPE to the Swiss tax expert community.

Others

• Kalaidos Law School: Swiss private law school partnering with ISIS on the SIST study programs. Relevant as an academic ecosystem participant rather than a direct competitor; share overlap in Swiss tax curriculum.
• Universität St. Gallen — Institute of Law and Economics: Swiss academic institution offering tax law research and executive education. Comparable as a Swiss source of high-level tax expertise and CPE, though research-driven rather than practitioner-seminars focused.
