Corporate and Tax Consulting


Welcome to SIRON SA

Founded in 1996, since its inception Siron has been based in Bellinzona, a strategic and easily accessible region that represents the lifeblood between the north and south of the Canton of Ticino.

Since it was established, Siron has been able to respond to the needs of its customers in a professional and timely manner, offering corporate and tax advice to companies and individuals.

In 2016, the company joined the Guardian SA and BCO Lyon SA Groups, and has thus broadly diversified its offer ensuring a service of excellence that ranges from business to asset consultancy, and which also extends to the Lugano region, the financial centre of the Canton of Ticino area.

Siron employs expert and qualified personnel able to assist clients in a professional and proactive way. The Company's long experience has enabled it to competently and concisely hone in to resolve various issues.

Thanks to its quality assurance system, and the presence of qualified auditors who can ensure the best execution of the assignment, Siron can act as a corporate auditor.
