Norway Approves Mandatory B2B E-Invoicing from 2027 and Digital Bookkeeping by 2030
Norway has formally approved mandatory B2B electronic invoicing and digital bookkeeping requirements following Parliament’s adoption of amendments to the Bookkeeping Act under Prop. 44 L (2025–2026).
The reform marks a significant step in Norway’s digitalization of business reporting and tax compliance. From 1 January 2027, businesses subject to Norwegian bookkeeping obligations will be required to issue structured electronic invoices in B2B transactions. By 1 January 2030, the obligation will expand to include the receipt of electronic invoices and the compulsory use of digital bookkeeping systems.
The government has presented the measures as part of a broader effort to modernize business administration, reduce manual processes, improve data quality, and strengthen tax control.
Two-stage implementation
The new regime will be introduced in two phases:
- 1 January 2027: Mandatory issuance of structured B2B electronic invoices.
- 1 January 2030: Mandatory receipt of electronic invoices and mandatory use of digital bookkeeping systems.
The requirements will apply to entities with bookkeeping obligations in Norway. Businesses below the NOK 50,000 threshold are expected to be exempt from the obligations.
Detailed technical rules are expected to be finalised during 2026. These will include approved invoice formats, transmission requirements, and possible exemptions. Norway’s existing EHF format, which is based on the Peppol framework, is expected to form the foundation of the mandate.
E-invoicing as a compliance and productivity reform
The Norwegian government has framed the reform primarily as an efficiency measure. It estimates that the transition to structured e-invoicing and digital bookkeeping could generate approximately NOK 10 billion in economic benefits over a 20-year period.
These benefits are expected to come from automation, reduced manual invoice handling, fewer administrative errors and lower processing costs for businesses.
However, for VAT, tax and finance professionals, the compliance implications are equally important. Structured e-invoicing creates standardised transaction data, while digital bookkeeping systems provide stronger end-to-end audit trails. Together, these measures reduce manual touchpoints, improve data quality and support more effective tax supervision.
In practice, the reform is not only a productivity initiative. It is also a significant step towards greater tax transparency and real-time compliance capability.
A move towards platform-based compliance
The most strategic aspect of the reform may be what comes next. The Ministry of Finance has asked the Norwegian Tax Administration, Skattedirektoratet, to assess further digitalisation measures before the end of 2026.
These may include:
- B2C e-invoicing
- Digital receipt, or e-receipt, requirements
- Further regulation of accounting software providers
- Expanded digital bookkeeping and reporting obligations
This suggests that Norway is moving towards a broader platform-based compliance model, where accounting systems, invoice exchange networks and tax reporting infrastructure become more closely integrated.
Peppol, EHF and Norway’s existing e-invoicing framework
Norway already has a well-established e-invoicing infrastructure. Mandatory B2G e-invoicing was introduced in 2019, requiring suppliers to public authorities to issue electronic invoices.
The country currently relies on two key standards:
- EHF—Elektronisk Handelsformat, based on UBL, or Universal Business Language.
- Peppol BIS 3.0 and the Peppol eDelivery Network, particularly relevant for cross-border transactions.
Norway has fully implemented the European standard on e-invoicing, including EN 16931. The private sector already uses a wide range of Peppol BIS-compliant solutions, providing a strong technical basis for the upcoming B2B mandate.
What businesses should do next
Businesses operating in Norway should begin assessing their invoicing and bookkeeping processes well ahead of the 2027 deadline. Key preparation steps include reviewing current invoicing formats, confirming system compatibility with EHF and Peppol requirements, and evaluating whether accounting systems can support automated receipt, processing, and digital recordkeeping.
Although detailed regulations are still expected in 2026, the direction of travel is clear. Norway is moving towards mandatory structured digital transaction data, greater automation, and more integrated tax compliance.
For businesses, early preparation will be essential to avoid implementation pressure as the 2027 and 2030 deadlines approach.
