Norway Locks In Mandatory B2B E-Invoicing: What the 2027 Start Really Means for Businesses

• From proposal to law. After a consultation launched in 2025 and an accelerated timeline, the Norwegian Parliament approved mandatory B2B e-invoicing and digital bookkeeping in June 2026 (via amendments to the Bookkeeping Act), moving Norway decisively toward a fully digital VAT and accounting framework.

• A two-phase rollout. Structured e-invoice issuance becomes mandatory from 1 January 2027 for businesses whose buyers are registered in the ELMA/Peppol directory, followed by mandatory receipt plus compulsory digital bookkeeping from 1 January 2030 — with PDF and paper invoices no longer valid for B2B.

• Broad scope, EU-aligned standards. The rules apply to all bookkeeping-liable entities — including foreign companies VAT-registered in Norway — and rely on the EHF format built on Peppol BIS 3.0 and the European EN 16931 standard, explicitly aligning Norway with the EU’s VAT in the Digital Age (ViDA) direction.

Article

Norway has taken one of the most significant steps yet in its digitalisation agenda, converting years of consultation into binding law. What began as a proposal to modernise the Bookkeeping Act has now cleared Parliament, setting a firm course toward structured electronic invoicing and, ultimately, fully digital accounting.

From consultation to statute

The path was deliberately compressed. Following a consultation the Ministry of Finance published in mid-2025, the government confirmed in March 2026 that it would bring the mandate forward by a full year — from an original 2028 target to 2027. Parliament then approved the reform in June 2026 through amendments to the Bookkeeping Act (Law-2026-06-19-39), with the Directorate of Taxes tasked to finalise the technical detail. Notably, the legislation also clarifies core definitions — including what qualifies as an “electronic invoice”: a sales document issued, sent and received in a structured electronic format suitable for automated processing.

A phased timeline

Norway has opted for a staggered introduction to give businesses room to adapt:

• 1 January 2027 — mandatory issuance. Bookkeeping-liable businesses must issue structured e-invoices to buyers registered in the national Electronic Recipient Register (ELMA), which is integrated into the Peppol directory. PDF invoices sent by email will no longer satisfy the requirement. [taxnews.ey.com], [e-invoice.app]
• 1 January 2030 — mandatory receipt and digital bookkeeping. All businesses must be able to receive e-invoices and must keep accounts in a qualifying digital bookkeeping system capable of automated invoice booking. Spreadsheets and word processors will no longer be acceptable for bookkeeping. [vatupdate.com]

The obligation is deliberately asymmetric: a supplier must begin issuing e-invoices once the buyer appears in ELMA, but buyers are not compelled to receive them before 2030 — so the shift away from paper and PDF happens progressively across the 2027–2030 window. [e-invoice.app]

Who is caught — and who is exempt

The scope is broad. The rules apply to all entities with bookkeeping obligations in Norway, regardless of where they are established — meaning foreign companies that are, for example, VAT-registered locally are expected to comply on the same terms as domestic entities. To preserve proportionality, exemptions are planned for micro-businesses with turnover below NOK 50,000 (roughly EUR 4,500) that are not otherwise required to keep accounts or file VAT returns, alongside carve-outs for certain financial sector entities such as banks, insurers and pension funds.

Formats and standards: EHF, Peppol and EN 16931

The mandate is drafted to be technology-neutral, requiring only a structured, standardised, machine-readable format — but the Directorate of Taxes has indicated that EHF (Elektronisk Handelsformat) version 3.0 or newer will be the standard, to be confirmed in secondary regulations. EHF is UBL-based, built on the Peppol BIS Billing 3.0 framework and aligned with the European semantic standard EN 16931, ensuring interoperability across borders. This choice is strategic: it explicitly anchors Norway to the EU’s VAT in the Digital Age (ViDA) direction and the B2B digital reporting requirements expected later this decade.

What still needs clarifying

Several details remain in the hands of the Directorate of Taxes, which must deliver draft regulations and assessments by 15 December 2026. Beyond confirming the format and small-business thresholds, the authority has been asked to consider extending digital requirements further — potentially to B2C transactions, digital receipts (e-receipts), and even a regulatory framework governing accounting software providers.

The bottom line

For multinationals, Norway’s move reinforces a now-familiar pattern across Europe: mandatory structured invoicing, tight EU-standard alignment, and a scope that pulls in foreign VAT-registered entities. Businesses operating in Norway should be assessing their invoicing systems, ELMA/Peppol connectivity and master data well ahead of the 2027 issuance date — and preparing for the deeper digital bookkeeping obligations that follow in 2030.
