Business records must be retained according to both tax law and commercial law. The duration of retention depends on the type of documents. In this article, you will learn which regulations apply, which documents must be retained, and what you should pay attention to. The principles of proper accounting are essential in this regard.

2. Retention Periods

As an entrepreneur, you must retain almost all business documents for at least six years. Some documents even require eight or ten-year retention periods. It is important to know which documents can be destroyed after which period. For example, financial statements and tax returns are among the documents that must be retained for specific periods.

As an employer, you must maintain payroll records and contribution proofs. These must be properly retained until the end of the year following the last audit by the pension insurance provider.

Different professions have specific retention obligations. For example, doctors must retain medical records and other medical documentation for ten years. Notaries, in turn, have extensive retention obligations for certain documents.

The business documents must be protected from external influences and be able to be reviewed by an expert third party. The readability of the documents and data carriers must also be ensured throughout the entire retention period.
