Norway Mandatory B2B E-Invoicing 2027: EHF Format & ERP Compliance
The Norwegian Government has officially advanced a legislative proposal to the Storting (Parliament) introducing a mandatory Business-to-Business (B2B) e-invoicing framework.
Crucially for global tax, finance, and IT teams, the deadline to start sending structured electronic invoices has been brought forward from 2028 to 1. Januar 2027. This timeline acceleration means businesses operating within the Norwegian market have a substantially shorter compliance window than initially anticipated.
Norway E-Invoicing Mandate: The 2-Phase Timeline
The new amendments to the Norwegian Bookkeeping Act eliminate traditional invoice formats in a phased rollout:
- Phase 1 (January 1, 2027) – Mandatory Issuance: All bookkeeping-obligated businesses must issue and send invoices in a structured electronic format for domestic B2B transactions. PDF invoices or paper documents will no longer qualify as valid.
- Phase 2 (January 1, 2030) – Mandatory Digital Bookkeeping: Businesses must implement qualifying digital accounting systems capable of automatically receiving, validating, and processing inbound structured e-invoices directly into accounts payable (AP) ledgers.
Who is In Scope? (Foreign VAT-Registered Companies)
The mandatory rules apply to all companies with bookkeeping obligations in Norway, regardless of where the business is legally established.
Critical Compliance Note: If a multinational corporation or foreign entity is VAT-registered in Norway, it holds local bookkeeping obligations under the Norwegian Bookkeeping Act. Consequently, foreign entities must comply with the exact same EHF requirements as local Norwegian corporations when invoicing domestic business partners.
Technical Specifications: EHF 3.0 and the Peppol Network
Norway operates a post-audit e-invoicing model built upon a mature, decentralized digital infrastructure. To successfully clear invoices under the 2027 mandate, your ERP or financial system must align with three technical components:
- EHF Billing 3.0 Format: Senders must generate invoices as structured XML documents using the Elektronisk handelsformat (EHF 3.0) standard, which is the local Norwegian adaptation of the Peppol BIS Billing 3.0 structure (compliant with European Norm EN 16931).
- ELMA Registry Lookup: Senders must automatically query ELMA (Norway’s electronic recipient register) to verify the buyer’s e-delivery address and capability before transmitting data.
- Peppol Access Point Delivery: Document exchange is completed strictly through the Peppol eDelivery network via accredited service providers using secure AS4 communication protocols. Senders do not submit invoices directly to the tax authority; instead, data integrity is verified via automated post-audits.
