A German Constitutional Court ruling upholds the country’s solidarity tax, a levy on top earners to help cover reunification costs.
Solidarity Tax Upheld by Germany’s Constitutional Court
A judge at Germany’s Constitutional Court has ruled that the country’s solidarity tax remains necessary to cope with the ongoing costs of reunification. The tax, which applies to the highest income earners, has been in place since 1991 and was reformed in recent years to sit at 5.5% of income.
The Federal Constitutional Court in Germany is a supreme court that interprets and applies the country's constitution, known as the Grundgesetz.
Established in 1951, it ensures that all laws and government actions align with the constitution.
The court consists of two Senate chambers: the First Senate deals with constitutional complaints, while the Second Senate focuses on federalism and state law issues.
Its decisions are final and binding, making it a crucial institution in Germany's democratic system.
History of the Solidarity Tax
The solidarity tax was introduced by the German government in 1991 to help cover the costs of reunification and support infrastructure in the formerly Communist eastern states. Over the years, the tax has undergone several reforms, with the rate decreasing from its initial introduction. However, despite this decrease, the number of taxpayers subject to the levy has fallen significantly in recent years.
A solidarity tax is a type of wealth redistribution tax imposed on high-income individuals or corporations.
It aims to reduce economic inequality by taxing those who have more wealth and resources.
The revenue generated from this tax can be used to fund 'social welfare programs, education, and healthcare'.
Solidarity taxes are often implemented in countries with significant income disparities, such as France and Sweden.
In 2012, the French government introduced a solidarity tax on high-income earners, generating an estimated €4 billion annually.
This type of tax has been debated worldwide, with proponents arguing it promotes 'social justice' and critics claiming it discourages entrepreneurship.

Court Ruling
Six members of the pro-free market Free Democratic Party (FDP) had challenged the tax, claiming that it violates the constitution because the government’s Solidarity Pact II expired in 2019. They also argued that the tax was unfair due to its impact on most taxpayers, who were exempt from the levy in recent years. However, the Constitutional Court judge dismissed these claims, stating that additional financing was still needed as a result of German reunification.
The judge emphasized that the solidarity tax is a temporary measure and would become unconstitutional if the need for it disappeared. The court’s ruling confirms that the tax remains necessary to address ongoing costs associated with Germany’s reunification.
Impact on the Economy
The solidarity tax has been a significant source of revenue for the German government, bringing in around €12.6 billion last year. If the tax had been declared unconstitutional, it would have created a similar-sized hole in the upcoming budget and forced the government to pay back around €65 billion collected since 2020.
Expert Opinion
Julia Jirmann, German tax expert, stated that the solidarity surcharge now applies only to top earners and is more urgently needed and fairer than ever. The fact that it only affects a small percentage of taxpayers does not make it any less legitimate, according to Jirmann.
