International Tax Law

Understanding Risks, Seizing Opportunities

Many companies and individuals have – or are planning – international business interests. From a tax perspective, cross-border activities are often highly complex. This applies to domestic taxpayers with foreign income (outbound) as well as foreign taxpayers with domestic income (inbound).

Germany has concluded 96 double taxation agreements (DTAs) for income taxes and six DTAs for inheritance and gift taxes (as of January 1, 2024), which determine which country has the right to tax specific income. The goal is to avoid double taxation.

Our team of certified international tax advisors is available to assist you in English if needed.

If you have a residence or habitual abode in Germany, you are subject to unlimited income tax liability. This means you must declare and pay taxes on your worldwide income in Germany. In most cases, a German income tax return must be filed.

If you also have a residence abroad, your taxation is determined by the double taxation agreement (DTA) between Germany and the respective country. Germany currently has DTAs with over 90 countries. The decisive factor is usually where a person has the center of their vital interests, such as family, job, and leisure activities.

If the employer has a permanent establishment or representative in Germany:

  • The employer is obligated to prepare a payroll for the employee.
  • As part of this payroll, the employer must calculate and remit the wage tax to the tax office.
  • Additionally, the employer must calculate and remit social security contributions to the relevant institutions.

If the employer has neither a permanent establishment nor a representative in Germany:

  • The employer is still obligated to prepare a payroll for the employee.
  • In this case, the employer must calculate and remit only the social security contributions to the relevant institutions.
  • The employee is responsible for declaring and paying income tax on their salary.
  • The employer is required to pay an employer’s contribution to social security in Germany, amounting to approximately 20% of the monthly salary.

This depends on the individual situation and the type of investment. We are happy to advise you; beforehand, you should consider the following questions:

  • What type of investment is planned: new establishment, establishment of a branch or subsidiary of a foreign company, private investment?
  • Is it important to limit liability, or are the risks so minimal that personal liability is not a concern?
  • How much equity capital will be invested?
  • Are individuals financially dependent on regular income from the company? If so, to what extent?
  • Should initial losses be tax-deductible for the involved individuals?
  • Is the company’s creditworthiness a significant factor?
  • Who are the business partners/customers? B2B or B2C?

Additionally, you should allow sufficient time if you need to open a business bank account with a German bank. This often requires numerous documents and, in some cases, multiple in-person appointments.

If you continue to have a residence in Germany after moving abroad, you remain subject to unlimited tax liability in Germany. Your taxation is then determined by the double taxation agreement (DTA) between Germany and the respective country.

Germany currently has DTAs with over 90 countries. The decisive factor is usually where a person has the center of their vital interests, such as family, job, and leisure activities.

It is essential to seek advice from a tax advisor in the respective country before moving to be informed about all tax obligations and applicable taxes on-site.

If you hold significant shares (i.e., at least 1%) in corporations, you should seek tax advice: at the time of moving, “exit taxation” (§ 6 AStG) may apply. This means that the move is treated as a fictitious sale of shares, and the fictitious gain (market value minus acquisition costs) is subject to taxation.
