About winstr AG

Established in 2019 by tax advisor Marco Streuli, this Zurich practice combines tax consultancy with a fiduciary division and works from the centre of the city. It acts for companies, entrepreneurs and individuals, and describes its client base as both Swiss and international. Tax work includes returns for individuals and legal entities, rulings, restructurings, succession planning and family office tax support. On the fiduciary side it keeps accounts, prepares annual and interim statements, runs payroll, advises on labour law and work permits, and implements company foundations, conversions, reorganisations and liquidations. Board mandates and general administration are also available. For matters outside its scope it calls on a network of law firms and specialists. The team is small, made up of a partner, a certified fiduciary, a consultant and an administrative assistant. The website is offered in German and English and publishes no prices.
