The Firm

Cortesi & Associati SA is a Swiss Firm which specializes in tax and business consultancy services based in Lugano.
The firm was established as a sole ownership in 1986 by Donato Cortesi, who had gained extensive professional experience as manager of a leading international consultancy and auditing firm.


Our managers and staff have a wealth of experience, and, over the years, our firm has built up an extensive network of correspondents in Switzerland and abroad.

The Company

In 1991, the firm was transformed into a limited company, the current Cortesi & Associati SA, and over the years, further highly qualified partners and managers joined the company. The current team, employing around twenty people, is formed by highly qualified consultants in the areas of taxation, accounting and HR management.

Cortesi & Associati SA has a subsidiary Cortesi Costa & Associati SA in Poschiavo (Canton of Grisons) which was incorporated in 2009, out of a merger with the former Poschiavo branch office of Cortesi & Associati SA.

The high level of specialisation, the thirty-year local presence in close contact with institutions, the economic and entrepreneurial world, as well as the constant investment in continuing education of the consultants make Cortesi & Associati SA the ideal partner, being able to offer an highly qualified, tailored, and dynamic service.

Cortesi & Associati SA is a member of ExpertSuisse, the Swiss leading association for Audit, Tax and Fiduciary services.
