ERP and accounting software for Norway: MVA, SAF-T, EHF

Norwegian compliance in one view

Running the books of a Norwegian business means registering for MVA once sales pass NOK 50,000 in twelve months, filing the MVA return every other month, keeping accounts that can be exported as SAF-T Financial, reporting pay monthly in the a-melding, and adopting annual accounts within six months of year end. From 1 January 2027 business-to-business invoices must also move to a structured electronic format. It matters because every obligation is read directly from the ledger.

Skatteetaten, the Norwegian Tax Administration, administers MVA, company tax, withholding and employer's national insurance contributions, and supervises cash register systems. Annual accounts go to the Register of Company Accounts at the Brønnøysund Register Centre. Accounting and bookkeeping rules sit in the Accounting Act and the Bookkeeping Act, both under the Ministry of Finance.

This page sets out what those rules require as of September 2026, where a finance system helps or gets in the way, and how Skyline Nexus ERP supports a Norwegian business.

• Tax authority: Skatteetaten
• Annual accounts: Register of Company Accounts, Brønnøysund
• Currency: Norwegian krone; standard MVA 25%
• EEA member outside the EU VAT area
• E-invoicing: B2B rule in force 1 January 2027; public sector since 2019

MVA rates, registration and returns

The general rate is 25%. Foodstuffs, and water and sewage services, carry 15%. Passenger transport, cinema tickets and the letting of rooms carry 12%, a rate that also covers accommodation, public broadcasting and admission to sporting events, amusement parks and experience centres. A restaurant bill, a hotel stay and a grocery basket can therefore carry three different rates.

A business must register in the VAT Register once its sales subject to MVA exceed NOK 50,000, excluding VAT, within any twelve-month period, which need not be a calendar year. Charitable and non-profit organisations have a NOK 140,000 limit. Until registration is complete a business cannot charge MVA on its invoices.

Most enterprises report and pay MVA every other month, paying at the same time as they file. An enterprise with taxable supplies under NOK 1 million a year, registered for at least twelve months and up to date with its returns, may apply between 10 December and 1 February for an annual period, with the return due on 10 March. Agriculture, forestry, reindeer husbandry and fishing businesses may use an annual period without the turnover limit, with the return due on 10 April. A return is required even when turnover is zero.

• 25% general rate
• 15%: foodstuffs; water and sewage services
• 12%: passenger transport, accommodation, cinema, sports events
• Registration above NOK 50,000 in any 12 months
• Bi-monthly returns as standard; annual under NOK 1 million on application

Being EEA but not EU: what changes in practice

Because Norway is outside the EU VAT area, the intra-EU machinery that Swedish, Danish or Finnish businesses use does not apply. There is no reverse-charge intra-Community acquisition of goods, no EC Sales List and no EU One Stop Shop. Goods bought from an EU supplier are imported through customs with import VAT, and goods sold to an EU customer leave Norway as exports, zero-rated for MVA with the buyer handling its own import.

For a finance system that means Norwegian tax codes rather than EU ones: domestic supplies at each rate, exports, import VAT and reverse-charge purchases of services from abroad each need their own treatment. The Bookkeeping Regulations spell out the specification of MVA that must be available per term, split by rate, domestic and foreign sales, and reverse-charge purchases.

The EEA link still matters elsewhere. The IFRS Regulation applies in Norway through the EEA Agreement, and electronic accounting records may be stored in another EEA state, the UK or Switzerland.

E-invoicing: EHF today, a legislated B2B requirement from 2027

Public-sector e-invoicing is already in place. Under the regulation on electronic invoicing in public procurement, in force since 2 April 2019, invoices under public contracts must be electronic, and the approved formats below the EEA threshold are EHF Billing 3.0 or later and Peppol BIS Billing 3.0 or later.

Business-to-business e-invoicing is now legislated. The Act of 19 June 2026 amending the Bookkeeping Act (mandatory digital bookkeeping and e-invoicing), adopted on the Storting finance committee's recommendation, adds three things. Sales documentation to other bookkeeping-obligated businesses must be issued in electronic invoice format, and purchase documentation received the same way. An electronic invoice is defined as a sales document issued, sent and received in a structured electronic format suited to automated processing, so a PDF does not qualify, and e-invoices must be stored in their original format. And bookkeeping must take place in an electronic accounting system.

By royal resolution of 19 June 2026 the e-invoice, documentation and storage changes take effect on 1 January 2027 and the electronic accounting system requirement on 1 January 2030. The Ministry may set further format requirements and exemptions by regulation, and the Storting's finance committee asked for the exemption power to be used flexibly so that the phase-in is practically workable. Check the final regulations before planning around a specific exemption: we are not going to invent transitional rules that have not been published.

• Public contracts: EHF or Peppol BIS Billing 3.0 since 2019
• 1 January 2027: B2B invoices issued and received as structured e-invoices
• 1 January 2027: e-invoices stored in their original format
• 1 January 2030: bookkeeping in an electronic accounting system

SAF-T, bookkeeping discipline and record retention

Since accounting periods starting on or after 1 January 2020, businesses with a bookkeeping obligation whose accounts are available digitally must be able to export them in the standardised SAF-T Financial format. Businesses with turnover under NOK 5 million are exempt unless their records are held digitally. The file is submitted only when the Tax Administration asks, typically in an audit. The format has been revised: version 1.40 can be used now and is the only valid format from 1 January 2027, while 1.30 can be used until 31 December 2026 and 1.20 is no longer valid.

The Bookkeeping Act is strict about corrections. Once the bookkeeping deadlines have passed, booked information may not be changed or deleted; the correction is a new documented posting that reverses the original in full. Accounting periods must be closed within those deadlines so that entries are secured against change. Specifications and documentation must be in Norwegian, Swedish, Danish or English, and sales documents must use one of those languages.

Bookkeeping is in Norwegian kroner unless the regulations allow otherwise; they permit bookkeeping in a functional currency other than NOK, but amounts in VAT reporting are fixed in kroner at the rate on the invoice date and payroll amounts at the rate on the payment date. Retention is five years for the core material and three years and six months for contracts, correspondence and packing slips, and booked information held electronically must stay electronically available for three years and six months.

Company accounts, filing and the audit exemption

Norwegian companies report under the Accounting Act, with simplifications for small enterprises; listed groups apply EU-adopted IFRS in their consolidated accounts through the EEA Agreement, and the Act allows those listed companies to prepare their own company accounts under IFRS as well. The financial year is the calendar year, and a different year is allowed only where seasonal business makes the accounts more informative, or for a branch or subsidiary of a foreign company that wants to match its parent.

The annual accounts and directors' report must be adopted no later than six months after the end of the financial year, and sent to the Register of Company Accounts no later than one month after adoption, so a calendar-year company's deadline is 31 July. Since the 2023 income year, limited companies must submit their tax return from an accounting system or through an accountant.

A limited company can decide by general meeting to dispense with audit if its operating revenue and balance sheet total are below thresholds set by regulation and it has no more than ten full-time equivalents on average. A parent company can only do so if the group as a whole qualifies, and the decision takes effect only when registered in the Register of Business Enterprises.

Payroll: the a-melding and employer's contributions

Norwegian employers file one monthly report, the a-melding, to NAV, Statistics Norway and the Tax Administration, covering income, employment, withholding tax, employer's national insurance contributions and financial activity tax. Employer's national insurance contributions are regionally differentiated: each municipality belongs to a zone, and for 2026 the rates run from 14.1% in zone I down to 0% in zone V for ordinary industries.

For the ledger the consequence is a payroll journal every pay run, a monthly reconciliation of withheld tax and employer's contributions to the a-melding, and, for businesses with units in several municipalities, contributions that follow the zone of each municipality.

Cities and regions: where the rules differ

MVA, bookkeeping and accounting rules are national. A business in Oslo, Bergen, Trondheim, Stavanger, Drammen, Kristiansand, Fredrikstad, Sandnes, Tromsø or Bodø charges the same rates, files the same MVA return and keeps the same SAF-T-ready books.

Two things genuinely differ by place. The first is employer's national insurance contributions: Oslo, Bergen, Trondheim and Stavanger sit in zone I at 14.1%, while municipalities in Northern Norway, including Tromsø and Bodø, sit in lower zones, and zone V in the far north pays 0% for ordinary industries. A company with offices in Oslo and Tromsø therefore pays different contribution rates on identical salaries.

The second is Svalbard and Jan Mayen. The VAT Act applies to the mainland and territorial waters but not to Svalbard, Jan Mayen or the Norwegian dependencies, so a supplier in Tromsø shipping to Longyearbyen needs a tax treatment for sales outside the VAT area.

How Skyline Nexus ERP handles Norwegian requirements

Skyline Nexus ERP is a cloud ERP with a double-entry general ledger under the Fiscal Authority menu, and its correction rules match Norwegian bookkeeping discipline. Posted journals are corrected by reversal, which creates a mirror-image posted journal and marks the original reversed, rather than by editing. Fiscal periods can be soft-closed or locked, and a locked period cannot be reopened, which is how periods are secured against change once the bookkeeping deadlines pass. The Accounting Audit Trail records who created, posted or reversed an entry with old and new values.

With the auto-post switches on, which start off, sales, purchases, payments, expenses and depreciation post balanced journals with output VAT computed per line, so 25%, 15% and 12% lines each post at their own rate. The VAT Return screen prefills bases and VAT for a date range, ready for the bookkeeper to enter in the MVA return, and the Audit Pack exports a calendar year's chart of accounts, trial balance, general ledger, journal lines and VAT summary to one Excel workbook for the accountant.

National e-invoicing and reporting connectors are being rolled out market by market, and EHF and Peppol BIS invoicing and the SAF-T Financial 1.40 export for Norway are part of that programme: tell us your country and we will confirm your go-live date. Until they are live for your company, the working route is a Norwegian e-invoicing access point fed through a partner-led integration using the Skyline Nexus ERP Connector REST API, with the statutory ledger and SAF-T file kept in a Norwegian accounting system where required. Payroll and the a-melding run in Norwegian payroll software or through a payroll partner, with the payroll journal posted each month, and cash sales are recorded in a product-declared cash register system. The interface language selector includes Norwegian; the accounting screens display in English.

Rates, regimes and deadlines in this summary change, and many countries are actively legislating on e-invoicing. This is general information, not tax or legal advice — confirm the current position with the authority named above or with your tax adviser before you rely on it.
