Executive Summary

Norwegian bookkeeping obligation applies to anyone carrying on business activity who must submit tax returns for wealth and income or VAT, and to enterprises with accounting obligation under the Accounting Act.[web:104][web:105][web:110]

The bookkeeping rules are laid down in the Bookkeeping Act and Bookkeeping Regulation and answer practical questions such as what information vouchers and invoices must contain, how bookkeeping systems must function and how long vouchers must be retained.[web:105][web:377]

Primary accounting documentation must generally be retained for five years and secondary documentation for three and a half years, with longer minimum retention for certain sectors and transactions; bookkeeping information stored electronically must remain electronically available for three years and six months after the end of the accounting year.[web:377][web:381][web:383][web:379]

Norway has adopted new legislation making digital bookkeeping and e‑invoicing mandatory for entities with bookkeeping obligations, with key Bookkeeping Act provisions effective from January 1, 2027 and a full mandate for electronic accounting systems phased in by January 1, 2030.[web:109][web:379][web:108]
