These files hold structured tax information including personal details, income data, deductions, and calculated tax figures that are used in a German income tax declaration.
How They Work

The files are an internal format meant to be processed by the tax software.

The structure is tailored for the 2021 tax cycle and may vary from other years.

They are not designed to be manually edited with a plain text editor.
