Estimate Kirchensteuer at 8% (Bavaria & Baden-Württemberg) or 9% (other states) of your income tax.
Only members of a tax-collecting religious community pay Kirchensteuer. It's calculated as a percentage of your income tax bill — 8% in Bavaria and Baden-Württemberg, 9% in all other German states.
Illustrative estimate only, using simplified/rounded 2026 German tax figures — not tax advice. The income tax figure uses a smoothed approximation of the official §32a EStG progressive formula, not the exact quadratic zone formula. Always confirm with the Finanzamt or a Steuerberater.
