Peppol Country Guide · Norway
Build for Norway before 1 January 2027
Norway is extending structured electronic invoicing from its mature public sector model to domestic business transactions. The transport pattern is familiar Peppol, but vendors must implement Norwegian EHF validation, participant discovery and original format archiving.
Legal Basis and Scope
Two legal tracks, one network, a widening obligation
Norway is extending its mature public sector e-invoicing model to business-to-business trade. There are two parallel legal tracks, a phased timeline, and a defined scope.
Here is what every vendor needs to know before the 2027 deadline.
The two legal tracks
Regulation 444 of 1 April 2019 implements EU Directive 2014/55/EU through the EEA framework. Since 2 April 2019, all public contracting authorities must be able to receive and process electronic invoices through Peppol. Regulation 444 places no direct duty on suppliers to send. Instead, buyers must require an approved format in their contracts for procurements announced from that date. Central government agencies had already been required to receive from 1 July 2011, and from 1 July 2012 to require their suppliers to send.
Act 39 of 19 June 2026 amends sections 3, 7, 10, 11 and 13 of the Bookkeeping Act. Sales documents between entities with bookkeeping duty must be issued in a structured electronic invoice format. The receipt and digital bookkeeping duties follow on 1 January 2030.
Scope
| B2B | B2G | B2C |
|---|---|---|
| From 1 January 2027, sales between entities with Norwegian bookkeeping duty must be issued as electronic invoices. Until the receive duty applies on 1 January 2030, the send duty in practice only applies when the buyer can receive electronic invoices. Peppol registration is the main way to establish this. If the buyer can receive, a PDF invoice is not accepted. | Covered public procurements already require approved structured formats and Peppol reception. Buyers must include the requirement in contracts. Sensitive content may be excepted where confidentiality cannot be protected. | Consumer invoicing is not in the enacted B2B amendment. The government has commissioned further study of possible consumer invoice and electronic receipt requirements. |
Vendor implication: The format and exemption rules are now set in the Bookkeeping Regulation, but some rules apply in stages. Alternative structured formats are allowed until 1 January 2030. Build a configurable country profile rather than hard-coding one rule set.
The Bookkeeping Act
Bokføringsloven explained
The Norwegian Bookkeeping Act (Lov om bokføring, LOV-2004-11-19-73) is the national law that governs how entities with bookkeeping duty must record, document, retain and make available their accounting information. It is separate from the public procurement electronic invoice regulation, and it is the law that Act 39 of 2026 amends to introduce the B2B electronic invoice and digital bookkeeping duties.
Who is in scope: Bookkeeping duty applies to anyone with accounting duty under the Accounting Act, and to anyone who runs a business with a duty to submit an income or VAT tax return.
Core principles: Section 4 sets out ten fundamental principles, including a proper accounting system, completeness, reality, accuracy, being up to date, documentation, two way traceability between documents and reporting, retention, security and good bookkeeping practice. Section 6 requires traceability, and Section 10 governs documentation of recorded information.
Retention and location: Section 13 requires primary accounting material to be retained for five years after the end of the financial year, and certain other material for three years and six months. Under Act 39 of 2026, electronic invoices must be kept in their original structured format. Accounting material must generally be retained in Norway, with an applicable EEA state exemption pathway set out in the Bookkeeping Regulation.
Implications for businesses: Covered businesses must move from manual or analogue bookkeeping to an electronic accounting system by 1 January 2030, issue structured electronic invoices to other covered businesses from 1 January 2027, receive purchase invoices electronically from 1 January 2030, and store the original invoice format for the five year retention period while keeping material accessible in Norway. Gross violations can be prosecuted with imprisonment up to six years.
Implementation Timeline
From public sector adoption to a national B2B mandate
The public procurement electronic invoice regulation entered into force for covered procurements.
Act 39 of 2026 amended the Bookkeeping Act and was formally enacted.
The Tax Directorate set the approved formats and a transitional rule for other structured formats until 1 January 2030 in the Bookkeeping Regulation.
Sales documents between entities subject to Norwegian bookkeeping duties must be issued in a structured electronic invoice format.
Electronic bookkeeping becomes mandatory and purchase documents between covered businesses must be received electronically.
EU ViDA digital reporting starts for covered cross border EU transactions. This is an EU comparator, not a Norwegian domestic reporting deadline.
Architecture
Peppol four corner delivery
The sender and receiver each connect through an Access Point. The sender Access Point discovers the receiver capability and destination through Peppol service metadata, validates the document, and delivers it directly to the receiver Access Point.
No government clearance: Norway uses peer to peer delivery over Peppol. The invoice does not pass through the Norwegian Tax Administration for approval before the buyer receives it. ELMA is the national service metadata publisher, mandatory for public entities, not a clearance portal.
Invoice Format
EHF Fakturering 3.0 and EN 16931
EHF Fakturering 3.0 is the Norwegian implementation of Peppol BIS Billing 3.0 and EN 16931. It uses UBL syntax. For public contracts below the EEA threshold, Regulation 444 accepts EHF 3.0 or later and Peppol BIS Billing 3.0 or later. Above the threshold, another approved format implementing EN 16931 may also be accepted. For B2B, the Bookkeeping Regulation approves EHF Fakturering, Peppol BIS Billing, EHF Selvfakturering and Peppol BIS Self-Billing, version 3.0 or later, from 1 January 2027.
- EHF Fakturering 3.0
- Peppol BIS Billing 3.0
- EHF Selvfakturering 3.0
- Peppol BIS Self-Billing 3.0
- EN 16931 semantic rules
- UBL invoice and credit note syntax
- Norwegian business terms and validation
- EDIFACT (allowed until 1 January 2030)
- E2B (allowed until 1 January 2030)
- PDF, scanned paper or image attachment (allowed until 1 January 2030 but only when the buyer cannot receive electronic invoices)
Recipient identity: Use the Peppol participant identifier with scheme 0192 and the Norwegian organisation number. Verify document capability through Peppol discovery and ensure the recipient is registered through ELMA or another relevant Peppol SMP.
Reporting Obligations
Delivery is not real time tax reporting
The 2027 mandate changes the format used to issue invoices. It does not establish continuous transaction reporting to the tax authority and it does not add a tax authority as a fifth corner. Existing VAT returns and other accounting reporting continue separately.
Under the Bookkeeping Regulation, a sales document must generally be issued as soon as possible and no later than one month after delivery, unless a specific rule applies. Received invoices follow normal bookkeeping and periodic reporting controls. The law does not create a separate deadline for transmitting received invoice data to the tax authority.
EU ViDA introduces digital reporting for covered cross border EU B2B transactions from 1 July 2030. Norway is not an EU Member State, so vendors should treat ViDA as an interoperability direction and monitor any future domestic implementation rather than assume direct application.
No fixed fine per invoice
| Violation | Consequence or fine |
|---|---|
| Supplier fails to provide an approved electronic invoice under a covered public contract | The public buyer may withhold payment until a compliant invoice is delivered. The original payment period then runs from compliant delivery. |
| Breach of the Bookkeeping Act electronic invoice duty from 1 January 2027 | No fixed amount per infraction is stated in Act 39 of 2026. |
| Technical outage or delivery failure | No automatic safe harbour is stated in Act 39 of 2026. Preserve evidence, retry records, validation results and delivery receipts. |

Frequently Asked Questions
Vendor implementation questions
No. An end user system can connect to an existing Peppol Access Point. The service provider carries the network agreement, transport, certificate, discovery and conformance responsibilities. Arratech provides that infrastructure through one integration, so your product does not need to operate its own Access Point.
The four corner transport, Peppol discovery and EN 16931 semantic model are familiar. Norway adds EHF validation rules, organisation number addressing through scheme 0192, ELMA registration and Norwegian tax and payment data. It is materially simpler than a clearance market because invoices do not pass through a tax authority platform before delivery.
The law requires a structured electronic invoice and delegates detailed format rules and exemptions to regulation. The regulation adopted on 29 September 2026 sets EHF Fakturering and Peppol BIS Billing, including their self-billing variants, in version 3.0 or newer as the approved standards from 1 January 2027. From 1 January 2030, all bookkeeping-liable businesses must be able to receive e-invoices, and only the approved standards may be used. Until then, other structured formats such as EDIFACT and E2B are also allowed, so vendors may need to support more invoice formats during this period.
Arratech provides Peppol transport, participant discovery, ELMA onboarding support, country validation, delivery evidence and a unified interface. Your product remains responsible for correct source data, business workflow and retaining the original invoice format for the statutory archive period.
