The importance of payroll tax for companies stems, among other things, from the fact that in collecting payroll tax as one of the most important sources of tax of all (more than EUR 200 billion per year), the Treasury uses companies themselves as agents.Ostensibly, payroll tax appears to be a mere tax on the employee, which the company “only” withholds and transfers to the tax office. However, this is not the case if we take a closer look, as the company is significantly affected. Indeed, not only do companies have to carry out an immense administrative burden, which is not free of charge, when withholding and paying payroll tax, but they are also liable when mistakes are made. The result of all this is that payroll tax is increasingly becoming a kind of corporate tax. Targeted strategic and operational payroll tax advice helps companies to minimize tax and administrative burdens.
Moreover, payroll tax has repeatedly proved to be contentious, but this is not surprising on closer inspection. Tax arrears often place a considerable burden on companies, are always untimely and are therefore difficult to calculate. Many companies have no choice but to fight with the tax authorities or in court for their right to do so. In addition, tax authorities are increasingly making criminal tax allegations, making contentious disputes inevitable.
In day-to-day business, payroll tax advice is available by telephone and email. Through short communication channels, companies receive quick and up-to-date answers to operational payroll tax questions and concrete proposals for action as well as brief feedback on their own work results.
Strategic payroll tax issues are worked out in detail in writing and are intensively discussed in a personal interview. Practical assessments of complex individual topics are the main focus and are reflected in expert opinions.

Companies based outside Germany that are expanding into Germany are guided by us through the administrative and legal requirements in all expansion phases. From hiring only one employee, to setting up a branch or subsidiary, to merging, selling or liquidating, we provide advice and assistance at all stages.
We accompany companies across borders and act as an interface with foreign consultants, service partners or other contact persons. Based on our many years of experience with companies coming to Germany from abroad, we know that “simple” things are complicated across borders. We bring this experience to the table when we support domestic companies in their expansion beyond Germany’s borders.
We offer solutions around the topics of restructuring, digitization, executive and team coaching and other transformation projects. By working together with us, you can be sure that your company not only meets current requirements, but is also prepared for what the future brings.
We believe that the issue of sustainability is fundamentally more than just compliance with legal requirements. The ESG criteria are good basic principles for responsible, smart and forward-looking corporate management and ensuring a healthy and sustainable life. The art is to integrate these principles in a meaningful, sensible and goal-oriented way.
The challenge of transformation lies in creating acceptance and commitment among all stakeholders and in agreeing on economic and sustainable goals of the company.
We are at your disposal for all legal questions. However, our focus is on business-related areas of law, in particular business law. Of course, tax law aspects are always taken into account. We accompany you from the establishment of a company, the choice of the right legal form, through the design or adaptation of company contracts, the drafting of employment contracts, right through to the planning and legal implementation of restructuring.
In specific areas such as patent law, industrial property rights, antitrust law, etc., we work with specialized cooperation partners in Germany and abroad.
