Company Description
Testor Treuhand AG is an independent, traditional fiduciary company based in Basel. Since 1945, we have been advising and supporting companies, institutions and private individuals in the areas of auditing, taxation, business consulting and fiduciary services. As generalists, we understand our clients' needs holistically and provide personal and individual support, from everyday administrative tasks to demanding consulting issues.
With us, long-standing experience and high quality standards meet short communication paths and personal collaboration. Our employees take responsibility, manage diverse mandates and have the freedom to develop professionally and personally.
Role Description
As Mandate Manager: Trust 60–100%, you will independently manage and lead client mandates in the area of trust and consulting. Your tasks include financial and payroll accounting, the preparation of annual financial statements as well as VAT returns.
Another focus lies in taxation. You will independently prepare tax returns for natural and legal persons and support our clients with tax-related questions. In addition, you will participate in the execution of limited audits, gaining insight into various companies and industries.
As the central contact person, you will personally and reliably support your clients and develop practical solutions for their fiduciary and tax concerns. Furthermore, you will contribute to the further development of internal processes and quality assurance.
The workload is 60–100%. Your workplace is Basel, with the possibility of partial home office work by arrangement.
