What is the KassenSichV?

The KassenSichV (Cash Register Security Regulation) is a German regulation effective since January 1, 2020. It specifies Section 146a of the Fiscal Code and regulates technical requirements for electronic recording systems — particularly TSE requirements, receipt obligations, and registration duties.

The 5 Core Obligations of the KassenSichV

These obligations arise from the Cash Register Security Regulation:

  1. TSE Requirement

    Every electronic POS system must have a certified Technical Security Device (TSE).

  2. Receipt Obligation

    A receipt must be issued for every transaction — on paper or digitally.

  3. Standardized Digital Interface

    Cash data must be exportable in the DSFinV-K format for tax audits.

  4. Registration Duty

    Electronic POS systems must be registered and deregistered with the tax office.

  5. Logging Duty

    All transactions must be logged completely — including cancellations and system events.

Consequences of KassenSichV Violations

Non-compliance can have significant consequences:

EUR 25,000

Fine

Violations can result in fines up to EUR 25,000.
