Guidelines and obligations for financial transparency

The Cash Register Security Ordinance of the German Federal Ministry of Finance defines standards to prevent cash register manipulation. As of September 30, 2020, German cash registers must have a technical security device (TSE). This stores transactions, issues a code and secures the data for the tax office.

German Cash Security Ordinance (KassensichV) – Technical Security Device (TSE):

Since December 22, 2016, the Federal Ministry of Finance (BMF) has created a new regulation of § 146a AO in the "Cash Register Act". According to this, electronic recording systems (cash register systems) must have a certified technical security device – TSE for short – from January 1, 2020. This TSE is intended to prevent manipulation of the digital (cash register or receipt) data.

In Germany, cash registers must be connected to a certified TSE in accordance with the KassensichV, all business transactions must be signed by it, and special data exports such as TSE tar files or a DSFinV-K export must be presented on request – with the use of the efsta EFR middleware, you are compliant with the law!

Requirements according to the Cash Security Ordinance (KassenSichV):

  • Bookings must be individual, complete, correct, timely and clear.
  • Daily recording of cash receipts and cash expenses.
  • Use of a TSE certified by the German Federal Office for Information Security (BSI) to verify the properness of digital records.
  • Receipt issuing obligation: Companies are obliged to issue receipts to customers immediately for recordable business transactions. The receipt issuing obligation is deliberately designed to be technology-neutral. Cash register owners are free to issue digital receipts, for example, by e-mail or to a mobile phone.
  • Financial authorities can check the properness of the records on site at the POS system without prior notice by means of a cash register inspection.
  • Technically secured archiving of all fiscal data in accordance with BSI specifications for the legally prescribed retention period (10/12 or 15 years).
  • Uniform digital interface (DSFinV-K): DSFinV-K is the digital interface of the tax authorities for POS systems. The data export has a clearly prescribed data format, according to which the transaction data of the cash registers and recording systems must be stored uniformly. The taxpayer must provide the data on request for a period specified by the auditor.
