What the Law Says
B2G E-Invoicing
E-invoicing is supervised in Norway by the Skattedirektoratet (Norway’s tax authority), and has been made mandatory for B2G transactions through the Regulations on electronic invoicing in public procurement [↗︎], implemented in three main phases:
- 2011: all central Norwegian public entities must be able to receive electronic invoices
- 2012: all suppliers of central public entities must send electronic invoices
- 2019: obligation extended to all Norwegian public entities
Norway B2G e-invoicing is based on a 4-corner model relying on the Peppol network. Suppliers are required to issue B2G e-invoices using EHF 3.0 format (Elektronisk Handelsformat), which is basically the Peppol BIS Billing 3.0 format including Norwegian specific national rules.
B2B E-Invoicing
Although there is currently no legal obligation to issue invoices electronically, the adoption of e-invoicing in Norway is already high.
From a regulatory perspective, invoices can therefore still be issued using several methods:
- Paper-based invoices
- PDF invoices with e-signature or complete audit trail
- EDI, usually in EHF (Elektronisk Handelsformat) 3.0 format, and sometimes in EDIFACT
In July 2025, the Norwegian Ministry of Finance published the results of an investigation [↗︎] into the future introduction of mandatory domestic B2B e-invoicing.
The report, complemented in March 2026 by a follow-up letter [↗︎], and formally approved in June 2026, recommends implementing an obligation in two phases:
- January 1, 2027 – Mandatory Issuance: all businesses subject to bookkeeping obligations in Norway must issue e-invoices to other businesses registered in ELMA (Peppol).
- January 1, 2030 – Mandatory Reception & Automated Accounting: businesses must be fully capable of receiving e-invoices and maintaining their financial records within a qualifying digital accounting system that allows for automated invoice booking.
The mandate will apply to all Norwegian companies, but the following entities should be exempted from the obligation:
- Micro-businesses with an annual turnover below NOK 50,000 (~EUR 4,500)
- Entities from a specific sectors, such as bankruptcy estates, financial enterprises, banks, insurance companies, and pension funds.
Further details should be confirmed by Skattedirektoratet (Norway’s tax administration) at the latest by December 15, 2026, and should rely on the Peppol network and the EHF 3.0 e-invoice format.
The investigation also suggests the potential introduction of a mandatory digital bookkeeping requirement, similar to the system established in Denmark under the Bookkeeping Act.

B2B E-Invoicing from 2027 in Norway: The Complete Guide
Norway’s Ministry of Finance announced future B2B e-invoicing obligations in two phases: sending from 2027 and full implementation in 2030.
Technical Details
E-invoice format
The predominant electronic invoicing format in Norway is EHF (Elektronisk Handelsformat), with the current 3.0 version based on the Peppol BIS 3.0 standard and adapted to Norwegian national rules.
According to a 2020 survey by Norges Bank, it represented 89% of the total e-invoice volume in the country.
EHF 3.0 is currently mandatory for all B2G transactions and is expected to serve as the required format if the proposed domestic B2B e-invoicing obligations are implemented in 2028 and 2030.
Other e-invoicing formats used for B2B transactions in Norway include EDIFACT and the local E2B (Electronic Commerce to Business).
E-invoice delivery
Where e-invoicing is mandatory for B2G transactions, and may become mandatory for B2B under the proposed obligations in 2028 and 2030, Norway uses a typical four-corner network model.
In practice, this system relies on the Peppol network, which enables the seamless exchange of e-invoices between senders and receivers through certified access points.
In 2024, the Skattedirektoratet participated in a pilot project to report VAT based on invoices exchanged between Nordic countries. This pilot explored a five-corner Peppol model, with the Norwegian tax authority acting as the fifth corner. However, this approach is not included in the proposed upcoming B2B e-invoicing obligation.
Upcoming B2B e-invoicing mandate (2027-2030)
Norway’s tax authority has proposed a framework that aims to introduce mandatory B2B e-invoicing, as well as mandatory digital bookkeeping requirements inspired by the Danish Bookkeeping Act.
While initially considering up to four different implementation scenarios, including maintaining the current optional regime, the following timeline was finally approved in June 2026 by the Parliament:
- January 1, 2027: mandatory issuance to all businesses registered in the national Electronic Recipient Register (ELMA)
- January 1, 2030: mandatory reception for all businesses in scope
The upcoming Norwegian e-invoicing mandate is expected to rely heavily on the Peppol network as its core infrastructure, as the expected e-invoice format should be EHF 3.0, which is the national implementation of Peppol BIS 3.0, and the ELMA has been integrated into the Peppol directory [↗︎].
In addition, the Skattedirektoratet proposes that taxpayers be required to use an electronic accounting system starting January 1, 2030, as this is considered a key element for cost savings in invoice reception, enabling automatic e-invoice booking.
The tax authority will also study if it would make sense for the mandate to possibly be extended to other areas such as B2C invoices and electronic receipts.
The Invoicing Hub Word
Norway
Norway is widely recognized for its advanced adoption of e-invoicing, even before broad B2B mandates were introduced. Early public sector initiatives and strong collaboration between authorities and businesses created incentives for suppliers to adopt electronic formats, driving adoption across the private sector.
The country has long maintained strong ties with the Peppol initiative, playing a key role in its early development and adoption. Norwegian authorities and businesses were among the first to implement Peppol standards, helping shape the network into the widely used European e-invoicing infrastructure it is today.
The approach of the Norwegian Tax Administration and the Ministry of Finance, promoting standardization and digital processes without immediate mandates, allowed businesses to adopt e-invoicing for efficiency and compliance benefits.
Now, Norway is moving toward a B2B e-invoicing mandate, following a global trend in Europe and beyond, even though it is not an EU member. By adhering to common e-invoicing standards such as Peppol and EN 16931, Norway ensures simpler cross-border transactions and improved efficiency for companies operating globally.
