In the city of Cologne, the largest city in the German state of Nordrhein-Westfalen, DORNBACH has been represented since 2011 after the merger with a rapidly growing auditing company founded in 2000. An attractive location for qualified employees and exciting companies in a lively and liveable environment!
Our services for you
We work with expertise and quality, flexibility and cost-efficiency. Our wide-ranging portfolio of services covers national tax law. Where aspects of internal and external (re)structuring as well as compliance and succession are concerned, we are in demand as specialists. The same applies to more exotic topics such as support for professional athletes and associations.
Cologne focuses on international tax matters (e.g. expatriates), in particular in close bilateral relationships with the Benelux companies acconAVM and Bofidi. In addition, we profit from our networks ShineWing International and GMN International.

Cologne is a vibrant city with important media, service, finance and commercial enterprises and a lively start-up scene, and characterised by its strong medium-sized companies. We support the whole region from the Lower Rhine to the Aachen area, the Bergische Land and Sauerland down to the Middle Rhine.
We focus on the areas of commerce, health care, IT and software, media, the drinks industry as well as freelancers (in particular lawyers, engineers & architects), non-profit organisations and foundations. Auditing and advice for public undertakings is also an important field.

Local roots, cross-regional activity
Since 2011, DORNBACH has been represented in the Cologne and Bergisch Gladbach offices. Here, we support organisations of all sizes: medium-sized and stock exchange listed companies, public institutions as well as foundations, societies and associations. The quality of our advisory and consulting services is excellent. With more than 50 employees, we are a high-performance part of the DORNBACH Group with its many specialists.
We are regionally well-known, rooted and networked. From Cologne & Bergisch Gladbach, we support clients with our advisory and consulting services in Nordrhein-Westfalen and the adjoining federal states, as well as throughout Germany.
