How to Correct Errors in Your German Tax Return

Overview

• Reporting on Wednesday said taxpayers should correct mistakes immediately if the Finanzamt has not yet issued the Steuerbescheid because earlier fixes are simpler and often accepted electronically.
• If the Steuerbescheid has arrived, check the Einspruchsfrist, which is generally one month from notification, and file an appeal within that window to challenge or amend the assessment.
• If the one-month appeal period has passed, the Abgabenordnung still allows certain changes for newly discovered facts and obvious clerical or calculation errors.
• Anyone who discovers an error that reduces their tax must report and correct it without delay and should seek professional advice for large sums or any case that could trigger tax-criminal inquiries.
• You can notify the Finanzamt in writing or electronically and a corrected electronic return is usually accepted, and taking quick, documented action can limit penalties and legal risk for honest mistakes.
