What is an ONSE file

ONSE files mostly belong to SteuerGo. ONSE files are specialized tax data files used in Germany. They use the ZIP format internally to bundle multiple documents and data required for tax filings.

Format: The file is a compressed archive, meaning it can store several files in one container.

Purpose: These files are used to store tax information and documents. They contain the data needed for processing German tax returns.

Usage: You can open them using any standard ZIP extraction tool. However, it is best to use the dedicated tax software provided by SteuerGo (or its alternative, SteuerSparErkl%C3%A4rung) to view and manage the contents effectively.

Note: Manual extraction and editing may affect the file’s integrity. For detailed assistance, visit the official website: SteuerGo.

FilExt.com tip: These files are mainly used to easily transfer and archive German tax data.
