Germany churches see rising tax revenue despite mass membership decline

German Catholic and Protestant churches are experiencing a financial paradox: while hundreds of thousands of members are formally leaving the institutions, total revenue from church taxes has increased. In 2025, approximately 660,000 people officially exited the churches—roughly 310,000 from the Catholic Church and 350,000 from regional Protestant churches.

Despite this exodus, the combined tax revenue for the 2025 fiscal year rose to approximately €12.5 billion, up from €12.4 billion in 2024. This growth is attributed to Germany’s progressive tax system and rising wages. Because the church tax is calculated as a percentage (typically 8% or 9%) of an individual’s income tax liability, the remaining members, who are often higher earners, contribute more in total.

To stop paying, individuals must undergo a formal process known as ‘Kirchenaustritt,’ which usually requires appearing in person at a registry office or local court. While those who leave can still attend services, they lose certain rights, such as the ability to serve as a godparent, have a church wedding, or receive a guaranteed church burial. Reasons for leaving include a perceived lack of relevance in modern life, institutional scandals, and financial considerations.
