Correct answer
there is a church tax that is linked to income tax and wage tax.
Explanation
In Germany, church tax is levied by the Länder tax authorities under the state church-tax acts; its base is the assessed income/wage tax (typically 8% in Bavaria and Baden-Württemberg, 9% elsewhere). The legal foundation is Article 140 of the Basic Law in conjunction with Article 137(6) of the Weimar Constitution, which grants public-law religious corporations the right to levy taxes. Declaring religious affiliation on the tax return (or via the ELStAM payroll system) serves solely to assess church tax correctly; non-members owe no church tax, and churches are not responsible for the tax return. Formal withdrawal from the church terminates liability from the following month, subject to Länder formalities and data-protection rules.
