In focus: Make the most of tax opportunities early

Many tax planning opportunities remain unused because important decisions are considered from a tax perspective too late.
Good tax planning therefore does not start in December. It should be considered early when making investment, distribution, business and private decisions.

Restrukturierung im Arbeitsrecht und Personalabbau

What employers need to consider under employment law when restructuring

Organisational changes, economic pressure or digitalisation may make larger-scale staff reductions necessary within a company. This is usually a multi-stage process and should be planned and implemented carefully. Mistakes in planning, social selection, works council involvement or any required mass redundancy notification can have significant legal and financial consequences.

Succession planning in hotels and restaurants: How to get it right

Succession in the hotel and restaurant sector determines the future of a lifetime’s work, the family, jobs and, in most cases, also a property. Those who consider the property, licence, staff and tax implications together at an early stage retain flexibility – and avoid mistakes that cannot be corrected later.

Dr. Felix Siegel was excellent in clarifying (over a 1 hour call) several international / Indian property-sale related implications for German tax-resident individuals. Highly recommend.

I can wholeheartedly recommend Kerstin Weidenbach-Koschnike. Especially in the area of tax structuring and international tax law, I felt comprehensively supported from the very beginning. The right questions were always asked—not just on the surface, but with a deep understanding of my individual situation and long-term goals. What impressed me most is that the quality of the advice becomes even more evident after implementation. Everything is well thought out, sustainable, and works in practice exactly as planned. Working together is also a great experience on a personal level—extremely friendly, warm, and at the same time highly competent. Even complex international matters are handled with confidence, and communication in English is seamless. Thanks to a strong global network, cross-border issues are covered exceptionally well. I would particularly highlight the strong entrepreneurial mindset—this is not just about optimizing taxes, but about thinking strategically and holistically. I am more than satisfied and would choose to work with this advisor again at any time.

I had a question for taxes and crypto, which I quickly got an appointment with Acconsis and had a good conversation with Dr Christopher Arendt. He explained the details well and answered all my questions.
