How Sahel Helps Clients

Sahel is a seasoned private client and international tax lawyer, well-versed with the needs and legal issues of relevance to large international families and entrepreneurs in Europe, the Middle East and Asia with U.S. connections. She has experience advising ultra-high-net-worth individuals (UHNWI) and families with respect to international cross-border tax planning (inbound and outbound), international trusts and estates for families of substantial wealth, and compliance with U.S. tax reporting requirements such as assistance with the Foreign Account Tax Compliance Act (FATCA). In addition, Sahel assists individuals with respect to reporting matters before the IRS, including representation in matters pertaining to the IRS Offshore Voluntary Disclosure Program(s) and the IRS Streamlined Filing Compliance Procedures. Sahel also provides advice pertaining to taxation and reporting of cryptocurrencies (e.g. Bitcoin).

Given her numerous years as a practitioner in Zurich, Switzerland, Sahel also has experience advising foreign financial institutions, fiduciaries and family offices in the private wealth sector with respect to U.S. tax reporting, regulatory and compliance matters.

What Clients Can Expect

Clients can expect to find Sahel professional, thorough and dedicated, with a high drive for excellence. The most important aspect of her success is her relentless presence and availability to each of her clients.

I have found that the reason I am hired is because clients trust my knowledge, judgment and the fact that I will be a zealous advocate for them. In addition, my expertise in U.S. federal taxes, fluency in additional languages and experience overseas in Europe and the Middle East provides a unique platform to connect with international families.

Outside the Office

Sahel enjoys tennis, skiing, horseback riding, reading, the arts and culinary endeavors. Had she not become a lawyer, she would have pursued a career as a writer or an art expert in Old Masters.
