Send Invoice in Norway

Sending invoices in Norway, particularly to public sector entities, is governed by a robust e-invoicing framework. Since April 1, 2019, it has been mandatory for all public sector entities in Norway to receive and process electronic invoices, and their suppliers are required to submit e-invoices rather than paper or PDF documents. This obligation is rooted in the Regulations on eInvoicing in Public Procurement (FOR-2019-04-01-444), which transposes the European eInvoicing Directive 2014/55/EU into national law. This means that any business supplying goods or services to Norwegian government entities must be capable of generating and delivering structured electronic invoices.

While Business-to-Government (B2G) e-invoicing is firmly established, Norway is actively exploring expanding these obligations to Business-to-Business (B2B) transactions. The Norwegian Tax Administration has launched a consultation on introducing mandatory digital bookkeeping and B2B e-invoicing for businesses subject to accounting obligations. Current proposals suggest a phased implementation, with mandatory issuance of electronic invoices for B2B transactions potentially starting from January 1, 2028, followed by requirements for businesses to receive electronic invoices and maintain fully digital bookkeeping systems from January 1, 2030.

For government contracts in Norway, specific electronic invoice formats are required to ensure interoperability and efficient processing. The primary formats mandated for Business-to-Government (B2G) transactions are EHF (Elektronisk Handelsformat) and Peppol BIS Billing 3.0. These formats are not mutually exclusive; EHF is Norway's national implementation, or Core Invoice Usage Specification (CIUS), of the broader Peppol BIS Billing 3.0 standard. Both are based on UBL (Universal Business Language), which provides a machine-readable, structured data format, enabling automated validation and processing.

Norway has fully adopted the European eInvoicing standard EN 16931. This means all public contracting authorities are legally required to accept and process electronic invoices that comply with this European standard, particularly for public procurement contracts above EU Public Procurement thresholds. The ELMA registry (Elektronisk mottakaradresseregister) plays a crucial role in this ecosystem. It serves as Norway's national directory for Peppol recipients, identifying organizations capable of receiving electronic invoices via the Peppol network.

Adhering to VAT compliance is a critical aspect of sending invoices in Norway, extending beyond merely stating the tax amount. Businesses must register for VAT with the Norwegian Tax Administration (Skatteetaten) once their taxable turnover exceeds NOK 50,000 within a 12-month period. Once VAT-registered, invoices for taxable supplies must clearly display the VAT charged at the correct rate, which is typically 25% for most goods and services, though reduced rates of 0%, 12%, and 15% also exist.

Key requirements for VAT documentation on invoices, as specified in the Norwegian Bookkeeping Regulations of 2004, include a distinct identification number, the date of issuance, the supplier's name and organization number followed by "MVA," and a detailed description of the goods or services. While Norway does not currently operate a real-time VAT reporting system for e-invoicing, businesses are required to submit VAT reports electronically to the Norwegian Tax Administration through the Altinn portal.

Businesses in Norway have several efficient methods for sending electronic invoices, primarily leveraging structured data and established technological frameworks. The most prevalent and mandated method for Business-to-Government (B2G) transactions is through the Peppol eDelivery Network. This network operates on a "four-corner model," where businesses connect to the network via a certified Peppol Access Point provider. This provider then securely transmits the structured e-invoice to the recipient's Access Point, which delivers it to the receiver's system.

Businesses can generate and send these structured e-invoices either directly from their internal Enterprise Resource Planning (ERP) or accounting systems, or by utilizing approved third-party e-invoicing solution providers. The use of structured e-invoices, such as EHF and Peppol BIS Billing 3.0, is crucial because they are machine-readable, enabling automated validation and integration directly into the recipient's systems, thereby enhancing processing efficiency and reliability.
