Only the German text of this Ordinance is authentic.
On the basis of section 146a (3) sentence 1 of the Fiscal Code (Abgabenordnung), as inserted by Article 1 no 3 of the Act of 22 December 2016 (Federal Law Gazette I, p. 3152), the Federal Ministry of Finance orders as follows, in agreement with the Federal Ministry of the Interior and the Federal Ministry for Economic Affairs and Energy and respecting the rights of the German Bundestag:
Section 1
Electronic record-keeping systems
(1) Electronic record-keeping systems within the meaning of section 146a (1) sentence 1 of the Fiscal Code are electronic or IT-supported point-of-sale systems or cash registers. The following are not considered electronic record-keeping systems:
1. ticket machines and ticket printers,
2. pay stations and parking ticket machines for parking space management as well as charging points for electric or hybrid vehicles,
3. electronic accounting programmes,
4. vending machines for goods and services,
6. cash and non-cash prize gaming machines.
(2) Electronic record-keeping systems within the meaning of section 146a (1) sentence 1 of the Fiscal Code also include
1. taximeters within the meaning of Annex IX of Directive 2014/32/EU (EU taximeters) and
The systems referred to in the first sentence also include app-based systems, provided they perform the function of an EU taximeter or odometer.
Section 2
Logging of basic digital records
Each time a business transaction or other process is to be recorded within the meaning of section 146a (1) sentence 1 of the Fiscal Code, an electronic record-keeping system must initiate a new transaction without delay. The transaction must contain the following:
2. a unique serial transaction number,
6. the process end time or process abort time,
8. the serial number of the electronic record-keeping system and the serial number of the certified technical security system and
The times specified in sentence 2 nos 1 and 6, the transaction number specified in sentence 2 no 2, the checksums specified in sentence 2 no 7 and the signature counter specified in sentence 2 no 9 must be established by the security module in a tamper-proof way. The transaction number must be constructed in such a way that any gaps in transaction records are detectable.
Section 3
Storage of basic records
(1) Ongoing business transactions or other processes within the meaning of section 146a (1) sentence 1 of the Fiscal Code must be stored on a non-volatile storage medium in a way that is complete, unmodified and tamper-proof.
(2) The stored business transactions or other processes within the meaning of section 146a (1) sentence 1 of the Fiscal Code must be concatenated as transactions in such a way that any gaps in the records are detectable.
(3) If the stored basic digital records are transferred, in whole or in part, from an electronic record-keeping system to an external electronic storage system, it must be ensured that the concatenation of all transactions in accordance with subsection (2) and compliance with the requirements for the standardised digital interface in accordance with section 4 are maintained.
(4) Compression of basic records in an electronic storage system is not permitted for the duration of storage in accordance with section 147 (3) of the Fiscal Code if this means readability cannot be guaranteed.
Section 4
Standardised digital interface
The standardised digital interface is a data set description for connecting the certified technical security system to the electronic record-keeping system as well as for standardised data export from the storage medium in accordance with section 3 (1), from the electronic storage system in accordance with section 3 (3) and from the electronic record-keeping system in accordance with section 1 (1) sentence 1 or subsection (2) for transfer to the tax authority official tasked with the cash register inspection or field audit. The standardised digital interface ensures a standardised documentation of the interface functions with parameters for connecting to the electronic record-keeping system as well as a standardised structuring and description of the data to be recorded in accordance with section 146a (1) of the Fiscal Code in a data schema and data field description for logging in accordance with section 2 and storage in accordance with section 3. This applies regardless of the manufacturer software. The standardised digital interface for standardised export from the storage medium in accordance with section 3 (1) and from the electronic storage system in accordance with section 3 (3), as well as the standardised digital interface for standardised export from the electronic record-keeping system, can be created and published separately from each other.
Section 5
Technical security system requirements
The Federal Office for Information Security, in consultation with the Federal Ministry of Finance, issues technical guidelines and protection profiles specifying the technical requirements for
1. the standardised digital interface, insofar as these technical requirements relate to standardised export from the storage medium and the connection of the certified technical security system to the electronic record-keeping system,
The requirements for the security module and the standardised digital interface include the technical and organisational requirements for the technical security system’s cryptographic keys, their associated cryptographic certificates and the certification infrastructure. The latest versions will be published in Part I of the Federal Tax Gazette and on the website of the Federal Office for Information Security.
Section 6
Requirements for receipts
A receipt must include at least the following:
1. the full name and the full address of the supplier,
2. the receipt issue date and the process start time specified in section 2 sentence 2 no 1 and the process end time specified in section 2 sentence 2 no 6,
3. the quantity and type of items supplied or the scope and type of services provided,
4. the transaction number specified in section 2 sentence 2 no 2,
5. the total amount of the consideration and the applicable tax amount for the supply or service and the applicable tax rate or, in the case of a tax exemption, a note that the supply or service is tax-exempt,
6. the serial number of the electronic record-keeping system as well as the certified technical security system and
7. the checksum of the process end specified in section 2 sentence 2 no 7 and the serial signature counter established by the security module.
The information specified in sentence 1 must be
1. readable for anyone without machine support,
2. readable using a QR code or
3. included in an electronic invoice in accordance with section 14 (1) sentences 3 and 6 of the VAT Act3.
The QR code referred to in sentence 2 no 2 and the structured part referred to in sentence 2 no 3 must each comply with the digital interface of the revenue administration (DSFinV) that is required for the type of record-keeping system in question. The applicable version of the digital interface will be published on the website of the Federal Central Tax Office. A receipt may be issued in paper form or, with the permission of the recipient, electronically in a standardised data format; other legal requirements remain unaffected.
