Norway has enacted a law making B2B e-invoicing mandatory in EHF/Peppol format from 1 January 2027. Paper invoices and PDFs will no longer be legally valid for transactions between companies subject to accounting obligations. A second wave of full automation is scheduled for 1 January 2030 (EDICOM, 19 June 2026).
Context: built on the Nordic model
Norway is one of the pioneers of the EHF format (Elektronisk Handelsformat), its own structured e-invoicing standard built on the Peppol protocol and UBL specifications. Mandatory e-invoicing in the public sector (B2G) has been in place since 2012. The 2027 law extends this logic to the private sector, aligning Norway with the broader European trajectory towards universal e-invoicing.
Only companies with annual revenue below NOK 50,000 that are not subject to bookkeeping obligations or VAT filing requirements are exempt. For all other companies — the vast majority — the obligation is total from 1 January 2027.
Impact for CIOs and CFOs
EHF via Peppol is non-negotiable. Unlike phased rollouts seen elsewhere in Europe — for example, the staggered timelines under the EU ViDA initiative or the UK’s Making Tax Digital programme — Norway sets a single, firm deadline. Any business still issuing invoices in PDF or paper format must migrate before 1 January 2027.
The ELMA registry is the technical entry point. Before sending an e-invoice, the sender must verify via ELMA (Elektronisk mottakeradresseregister) that the recipient is registered and capable of receiving EHF documents on the Peppol network. This is an operational prerequisite that is frequently underestimated: connecting your own organisation to Peppol is not enough — you must also confirm that each of your suppliers and customers is registered. IT teams must integrate this ELMA lookup into their invoice emission workflows.
ERPs with native compliance are a competitive advantage. Nordic ERP vendors — Visma, Monitor ERP, Tripletex — have supported EHF and Peppol natively for years. SAP, Microsoft Dynamics 365 and Oracle Fusion all offer certified connectors. Companies running solutions without a native Peppol connector will need a third-party Access Point, with the associated costs and lead times. The window for qualifying and deploying these connectors will narrow rapidly as 1 January 2027 approaches.
2030: a second wave to plan for now. The law stipulates that from 1 January 2030, companies must have “fully digital accounting systems capable of receiving and processing e-invoices automatically.” This goes beyond a technical upgrade — it is an ERP integration constraint that requires incoming invoices to be processed without manual re-entry. ERP projects starting today should build the 2030 threshold into their roadmap from the outset.
What to watch
Final implementation details — implementing decrees, clarifications on the ELMA perimeter, potential carve-outs for specific SME categories — will be published during 2026. The Norwegian Tax Administration (Skatteetaten) and Digdir (the Norwegian Digitalisation Agency, formerly Difi) are the primary sources to monitor. European businesses with subsidiaries or suppliers in Norway are directly in scope: compliance does not stop at Norway’s borders when they issue B2B invoices to Norwegian companies.
