About

Jill Blattmann practices in the areas of national and international tax law for legal entities. She mainly advises on company acquisitions and mergers, reorganization, and restructuring. Her expertise also lies in providing ongoing tax advice to legal entities.

“What I find appealing about my job is the challenge of optimally aligning tax regulations with individual circumstances in the best possible way, along with recognizing issues early and solving them with the necessary persistence, my drive, and empathy. Moreover, Swiss tax law is constantly changing. I find balance to my professional life in sport. Swimming, hiking, or snowboarding are the best ways for me to clear my head and recharge my batteries. Additionally, I enjoy traveling to foreign countries.“

Jill Blattmann speaks German and English.
