Norway's Parliament has mandated digital bookkeeping and e-invoicing for all businesses subject to accounting obligations under the Accounting Act of 17 July 1998 No. 56, with implementation deadlines set for 1 January 2027 and 1 January 2030. Businesses with annual turnover below NOK 50,000 are exempt from the digital bookkeeping requirement.
Norway’s Parliament (Stortinget) has passed legislation requiring digital bookkeeping and e-invoicing for all businesses subject to bookkeeping obligations, with implementation deadlines set for 1 January 2027 and 1 January 2030.
Under the Accounting Act of 17 July 1998 No. 56, companies would be required to maintain bookkeeping through digital systems rather than spreadsheets or paper, marking a significant shift in regulatory expectations.
Who must comply
The new rules apply to all entities subject to accounting obligations under the Accounting Act, which includes all limited liability companies.
Businesses generating annual turnover below NOK 50,000 will be exempt from the digital bookkeeping requirement, as will certain bankruptcy estates. The proposals also exempt financial institutions—including banks, mortgage companies, and securities firms—from the obligation to send and receive e-invoices, though they may still need to comply with other aspects of the regulation.
State-owned enterprises already face mandatory e-invoicing for procurements valued at NOK 100,000 or more (excluding VAT) under the Public Procurement Act of 17 June 2016 No. 73 and Regulations of 1 April 2019 No. 444.
What the requirements mean
The Norwegian Tax Directorate proposes mandatory digital bookkeeping across the board, replacing manual documentation methods. Under this system, all entities would be required to both send and receive electronic invoices—a structured, machine-readable format that allows automated processing.
Unlike PDF invoices or paper documentation, e-invoices are designed for system-to-system communication using standardised formats such as EHF (electronic commerce format).
The directive argues that digital systems provide built-in control mechanisms, reduce manual administrative work, and streamline the entire transaction chain from ordering through payment to reporting. Authorities also anticipate using SAF-T accounting files more extensively for compliance verification, benefiting both businesses and tax authorities.
Implementation timeline
Rather than introduce all requirements at once, the proposal suggests a phased rollout. Beginning 1 January 2028, businesses must be capable of sending e-invoices.
The obligation to receive e-invoices and maintain digital bookkeeping systems takes effect 1 January 2030. This staggered approach gives companies, particularly smaller operations, time to adapt their systems and processes.
The requirements exclude sales to consumers and cash sales, which remain subject to existing rules under the Accounting Act, Section 10a.
Data protection framework
All entities subject to the accounting obligation must comply with the Personal Data Act (Act No. 38 of 15 June 2018), which implements Regulation (EU) 2016/679 (the General Data Protection Regulation).
Processing personal data within bookkeeping systems is permitted based on the legal obligation—the requirement to fulfil accounting duties—making compliance with data protection laws an integral part of the new digital bookkeeping regime.
The proposals are designed to modernise Norwegian business practices while reducing compliance burden and supporting the development of new digital solutions in the accounting sector.
