In this article you will learn about the documents you need to provide to in case of a tax audit according to KassenSichV. The taxpayer is solely responsible for the legal evidence during a POS audit:


            1. Proof of TSS like purchase or contract.

            2. Connection to the TSS evidenced by test receipts

            3. Use of a certified TSS (certificate with all documents, see below).

            4. TAR-/DSFinV‑K Exports

            5. Process documentation

1. Proof of TSS like purchase or contract.

If your TSS purchase is reflected in the contract with Clock PMS+ you can use this contract as proof of purchase.

2. Connection to the TSS evidenced test receipts

You can also generate a test sale as proof.  The receipts can be checked using the fiskalcheck app from fiskaly.

3. Use of a certified TSS

The certification of the technical security system is evidenced by the following documents: 

    1. Certificate according to TR-03153, 

    2. Certificate of Conformity 

    3. Notice of conformity

    4. Environment protection concept

Note: For the proof of certification to be valid, all of the above documents are required. If a document is missing, the proof is incomplete.

You can download all the required fiskaly Cloud TSS documents from fiskaly's website:

- TR-03153 certificate;

- Conformity statement;

- Certificaton report;

- Environment protection concept.

4. TAR-/DSFinV‑K Exports
