E-Invoicing in Denmark

Denmark on the Road to B2B E-invoicing

Denmark is no newcomer to the world of e-invoicing – since 2005 it has been mandatory in the public sector (B2G) for public administrations and their suppliers (covering all suppliers for all contract work for all authorities). This means that transactions with public entities must be documented with electronic invoices.

In B2B relations, these issues are still under review, and e-invoicing is still voluntary, but entrepreneurs can exchange electronic invoices if both parties agree to it. In May 2022, the Danish parliament adopted a package of reforms regarding the Danish Accounting Act ("DBA"), which refers to the obligation to keep and archive accounts in digital format. It will be implemented successively. Under the DBA, all companies, regardless of size, that are currently required to submit an annual report and report it to the Danish Business Authority, will be covered by the new book-keeping rules via a digital accounting system from 1 January 2024.

Other companies less than DKK 300,000 subject to accounting, including partnerships, associations, branches, and others that are not required to file an annual report and report it to the Danish Tax Authority, will be covered by the new book-keeping rules via a digital accounting system from 1 January 2026.

Implementation timeline

January 2023 - requirements were published by the Danish Business Authority, for which system providers must adapt their products to the new regulations and apply to the Agency for approval of their systems.
Later in 2024 - the requirement for companies to use an approved system (accounting classes B, C and D) will come into force.
2026 - the requirement will also apply to personally owned accounting class A companies with a turnover of more than DKK 300,000.

Sole proprietorships with a turnover of less than DKK 300,000 will be exempt from the requirement to use a digital accounting system, but of course must still comply with all other requirements of the law.

E-invoicing process description

Denmark has a centralized model which also operates using the PEPPOL system. The entire system is supported by the official NemHandel platform. This is shared public digital infrastructure for the exchange of business documents between private companies and public authorities, the use of which has been in place since 2005. In order to send and receive digital business documents via the NemHandel platform, the company's accounting system must be connected to an access point that ensures that invoice data meets the necessary security standards.

PEPPOL in Denmark is a set of artifacts and specifications enabling cross-border e-procurement. The Danish Business Authority (ERST) is the PEPPOL Authority, which means that ERST is responsible for the registration of companies that wish to become a PEPPOL Access Point or a Service Metadata Publisher. ERST is also responsible for ensuring the long-term adoption of e-procurement using the PEPPOL network as the platform.

Archiving requirements for e‑Invoicing in Denmark

Companies must store accounting materials securely for a period of 5 years after the end of the financial year to which the material relates. As a matter of some interest, the requirement to retain accounting materials in Denmark has been abolished.
