- Denmark has cancelled the planned OIOUBL 3.0 e-invoicing format and will instead introduce a new standard, Nemhandel BIS 4 (Nemhandel 4.0), based on EN 16931, Peppol BIS 4.0, and a PINT-like methodology.
- The transition supports the final phase of Denmark’s Digital Bookkeeping Act (2026) and future EU VAT in the Digital Age (ViDA) requirements.
- OIOUBL 2.1 will remain in use until July 2029, with technical updates and a gradual migration to Nemhandel BIS 4 starting from 2028.
- Key open questions include whether Denmark will fully migrate to the Peppol network and the final technical specifications of Nemhandel BIS 4.
- The deadline for implementing the EU ViDA e-invoicing framework is July 2030.
