Norwegian Tax Authorities Outline Strict Invoice Requirements for Businesses

• Norwegian tax authorities require businesses to follow strict invoice numbering rules using only approved invoicing software or pre-printed forms from printing companies
• Invoices must include mandatory details such as sale date, seller and buyer information with organization numbers, product descriptions, delivery details, and VAT amounts in NOK
• Different VAT rates or non-VAT sales must be shown on separate invoice lines, and limited companies must include the word Foretaksregisteret
• Credit notes are required to correct invoices and must reference the original invoice while following the same documentation requirements
• E-commerce sales must follow standard invoicing rules even for instant online payments, except when goods are ordered online but collected in-store
