A particularly complex national tax law that is closely interlinked on an international level requires, as does hardly any other area, professional cooperation and an in-depth, professional exchange. The structures of SONNTAG are precisely oriented towards these demands. We work in a multidisciplinary manner, that is to say, across specialties in expert teams that are individually assembled for every client. On this basis, we succeed in providing detailed consulting and efficient assistance in all questions surrounding tax planning, tax advice, annual financial statements with myriad areas of emphasis, criminal tax law and voluntary declarations, advisory services, valuation projects, employee posting, group tax law and holistic consulting for large clients.
