fiskaltrust’s solutions for Germany
In Germany, the Kassensicherungsverordnung (KassenSichV) and §146a of the German Fiscal Code (AO) require that all point-of-sale (POS) systems securely record transaction data using a certified Technical Security Device (TSE). These measures are designed to ensure data integrity, support auditability and prevent tax evasion.
Key Requirements of KassenSichV:
- Individual Transaction Logging: Each cash and electronic transaction must be recorded individual ly in a tamper-proof and audit-safe format using a certified TSE.
- Receipt Issuance Obligation (Belegausgabepflicht): A receipt must be generated and offered to the customer for every transaction processed through the POS system. The receipt must include a digital signature generated by the TSE.
- TSE and POS Registration (Kassenmeldepflicht): Businesses are required to register each POS system and its corresponding TSE with the German tax authority via Elster. This can be done manually, guided, or ful ly automated through solutions like fiskaltrust’s Notification Service.
- Secure Data Storage: All transaction data must be stored in a revision-safe and tamper-proof way using hash chaining. The data must be made available in DSFinV-K and TAR format for audits by tax and customs authorities.
- Applicability: These obligations apply to all businesses operating electronic or digital POS systems in Germany, regardless of revenue thresholds.
Key Benefits for Developers
- Standardized API: Easy integration of fiscalization without adding complexity.
- Vendor Independence: Supports multiple TSE providers—no vendor lock-in.
- Regulatory Compliance: Adheres to KassenSichV and
§ 146a AO without changing core POS logic. - Future-Proof: Automatic updates to stay compliant with legal changes.
- Developer Support: Access to docs, examples, and tools for DSFinV-K, TAR and Elster.
Integration with the fiskaltrust Middleware API
