Why Zimmer & Partners?

A State-of-the-Art Luxembourgish Chartered Accountant with a Focus on Specialized Tax Advice

In the dynamic world of finance and taxation, where expertise and precision are paramount, Zimmer & Partners stands out as a beacon of innovation and tailored service.

At the heart of Luxembourg’s financial landscape, this firm has carved out a niche for itself, offering highly specialized tax advice that draws from a rich history and a profound understanding of both national and international fiscal complexities.

Our Beginnings

The Genesis of Excellence

The inception of Zimmer & Partners in February 2010 by Claude Zimmer, a luminary in the realm of taxation, was a testament to a vision that sought to blend the personalized touch of tailor-made services with the rigors of international standards.

This was not Claude Zimmer’s first venture into the intricate world of tax and corporate finance services. In 2009, he co-founded Lux Global Trust Services, an independent advisory firm that quickly became synonymous with impeccable service in international tax and corporate finance, until its merger in 2017 with S.G.G. S.A., now known as IQ EQ (Luxembourg) S.A.
