Norway Tax Regime

Norway combines a moderate flat corporate income tax of 22% with a dual personal income tax system that separates a flat tax on general income from a progressive bracket tax on gross employment income. Resident companies are taxed on worldwide income; a broad participation exemption (fritaksmetoden) largely removes economic double taxation within the corporate sector, while distributions to individuals bear an upward-adjusted dividend tax. The system sits outside the European Union but inside the European Economic Area, so EEA freedoms shape much of the international architecture, and Norway follows OECD standards on treaty policy, transfer pricing and the Pillar Two global minimum tax, implemented from 2024. Distinctive features include heavy resource rent taxation of petroleum, hydropower, onshore wind and aquaculture, a shipping tonnage tax regime, and an individual net wealth tax. Administration through the Norwegian Tax Administration (Skatteetaten) is highly digitalised and predictable.

1.1 Sources

Primary legislation includes the Tax Act (skatteloven), the Petroleum Tax Act (petroleumsskatteloven), the VAT Act (merverdiavgiftsloven), the Tax Administration Act (skatteforvaltningsloven) and the Supplementary Tax Act (suppleringsskatteloven) implementing the global minimum tax.

1.2 Recent developments

Norway implemented the Pillar Two income inclusion rule and a domestic minimum top-up tax from 1 January 2024, with the undertaxed profits rule following from the 2025 income year; the rules closely mirror the OECD model rules. A resource rent tax on onshore wind power applies from 2024 (25% effective rate, 47% marginal including ordinary corporate tax) and a resource rent tax on aquaculture from 2023 (25% effective, with a NOK 70 million group allowance). Withholding taxes of 15% on interest, royalties and certain lease payments to related parties in low-tax jurisdictions, introduced in 2021, remain in force. The individual exit tax on latent share gains has been materially tightened, and bracket tax and wealth tax thresholds continue to be adjusted annually.

2.1 Rates and residence

Companies — principally the AS (private limited company) and ASA (public limited company) — are subject to corporate income tax at a flat 22% if resident in Norway, i.e. incorporated under Norwegian law or effectively managed from Norway. Resident companies are taxed on worldwide income; non-resident companies are taxed on income from business conducted in or managed from Norway, including permanent establishments and Norwegian real property. Certain financial-sector companies (banks and other financial undertakings) pay corporate tax at 25% and bear an additional financial activities tax on payroll. There is no county or municipal corporate income tax.

Special regimes overlay the ordinary rate: upstream petroleum activity on the Norwegian Continental Shelf is taxed at a 78% marginal rate (22% ordinary tax plus a special tax applied sequentially at a technical rate of 71.8%); hydropower production above 10,000 kVA bears a 57.7% resource rent tax on top of ordinary tax (67% marginal); onshore wind and sea-phase aquaculture each bear a 25% effective resource rent tax (47% marginal); and qualifying shipping companies may elect into the tonnage tax regime, under which shipping income is permanently exempt and only net financial income is taxed at 22%.

2.2 Dividends and participation exemption

Under the participation exemption, dividends and capital gains on shares in companies resident in Norway or genuinely established in the EEA are exempt in the hands of a corporate shareholder, without minimum holding or ownership period for EEA shares; 3% of exempt dividends (not gains) are clawed back into taxable income, giving an effective charge of 0.66%, though the clawback does not apply within tax groups (more than 90% ownership). For shares in companies outside the EEA, the exemption requires at least 10% ownership and voting rights for a continuous period of two years, and never applies to companies resident in low-tax jurisdictions outside the EEA. Losses on shares covered by the exemption are non-deductible.

2.3 Income determination and deductions

Taxable income starts from the financial accounts but is determined under tax rules on an accruals basis: income is taxable when the right to it arises and costs are deductible when the liability arises, irrespective of payment. Business expenses incurred to earn taxable income are generally deductible; entertainment costs are largely non-deductible. Depreciation follows the declining-balance system with statutory asset groups: machinery and equipment 20% (with rules for green ships under consideration), vehicles and trucks up to 24%, office equipment 30%, buildings 4% (2% for high-standard structures, 10% for structures with short economic life), and acquired goodwill 20%. Inventory is valued at cost (FIFO); provisions are generally not deductible until the liability is incurred. Gains and losses on business assets are largely channelled through gain-and-loss accounts, bringing 20% of the balance to income (or deduction) annually.

2.4 Interest limitation

Net interest expense is deductible only up to 25% of tax EBITDA where net interest exceeds NOK 25 million for companies in a group (measured for the Norwegian part of the group), or NOK 5 million for stand-alone companies (for which only related-party interest is restricted). Group companies escape the limitation under a balance-sheet based equity escape: broadly, if the company's (or the Norwegian sub-group's) equity ratio is no more than two percentage points below the consolidated group ratio. Denied interest may be carried forward for ten years. External bank debt guaranteed by related parties can be recharacterised as internal for these purposes.

2.5 Losses

Tax losses may be carried forward indefinitely and offset in full against future taxable income — there is no percentage cap. Carryback is available only on the final liquidation of the company (two years). Loss carryforwards survive changes of ownership, but the tax authorities may deny them under the statutory anti-avoidance rule where use of the loss position is the predominant motive for a transaction.

2.6 Group taxation

There is no fiscal consolidation; instead, Norwegian group companies within a more-than-90% ownership and voting chain may equalise results through group contributions (konsernbidrag): the contribution is deductible for the payer and taxable for the recipient, up to the payer's taxable income. Contributions may pass between sister companies and via foreign EEA parents, and may in certain cases be made to EEA subsidiaries with final losses. The 3% dividend clawback does not apply to intra-group distributions, and assets may be transferred within a tax group at book value against security for the deferred tax.

2.7 Controlled foreign companies

Under the NOKUS rules, Norwegian participants are taxed currently on their proportionate share of the profits of a Norwegian-controlled company resident in a low-tax jurisdiction — one where the effective foreign tax is less than two thirds of the Norwegian tax that would have applied. Control exists where Norwegian taxpayers own or control at least 50% (attribution rules apply, and 60% at year-end triggers entry). For EEA entities, NOKUS taxation applies only where the entity lacks genuine economic activity (substance test); for treaty states outside the EEA, only where the income is mainly passive.

2.8 Transfer pricing

Norway applies the arm's-length principle in section 13-1 of the Tax Act, interpreted in line with the OECD Transfer Pricing Guidelines, which are given formal status. Companies with related-party transactions above NOK 10 million (or balances above NOK 25 million) file the RF-1123 controlled-transactions form with the tax return; entities in groups with 250 or more employees and revenue above NOK 400 million (or balance sheet above NOK 350 million) must prepare full documentation on demand within 45 days. Country-by-country reporting applies at the standard NOK 6.5 billion consolidated revenue threshold. Advance pricing agreements are available in practice for gas sales and through the mutual agreement procedure; the petroleum sector attracts particular transfer-pricing scrutiny.

2.9 Incentives

The principal incentive is SkatteFUNN: a 19% tax credit on qualifying R&D costs for projects approved by the Research Council of Norway, capped at NOK 25 million of costs per year (personnel costs capped at NOK 700 per hour, raised to NOK 850 from 2025), refundable in cash to the extent it exceeds tax payable. Regionally differentiated employer social security rates (from 14.1% down to 0% in the far north) function as a location incentive. Accelerated first-year deduction applies to petroleum and resource-rent investments under their special regimes, and the tonnage tax election exempts qualifying shipping income permanently.

2.10 Pillar Two

Norway's Supplementary Tax Act applies the 15% global minimum tax to groups with consolidated revenues of at least EUR 750 million in at least two of the four preceding financial years. An income inclusion rule and a qualified domestic minimum top-up tax apply for financial years beginning on or after 1 January 2024, and the undertaxed profits rule from the 2025 income year; the rules closely mirror the OECD model rules and administrative guidance, including the transitional country-by-country safe harbours. In-scope groups face a standalone information return and a Norwegian supplementary tax return, with the domestic top-up tax taking priority over foreign charging rules. The 78% petroleum regime and the resource-rent regimes generally leave Norwegian members comfortably above the 15% floor, but ordinary-rate entities with SkatteFUNN credits and tonnage-taxed shipping income require testing.

2.11 Branch income and reorganisations

A Norwegian branch (permanent establishment) of a foreign company is taxed at 22% on attributable profits determined under the authorised OECD approach; there is no branch profits or remittance tax, so after-tax branch profits may be repatriated free of Norwegian tax. Domestic mergers, demergers and conversions between Norwegian companies can be carried out with tax continuity where corporate-law procedures are followed and tax positions continue at book values; cross-border mergers within the EEA can likewise be tax-neutral where assets remain connected to Norwegian taxation. Where assets, functions or residence leave the Norwegian tax net, exit tax applies at market value, with deferral and instalment options for transfers within the EEA against any required security.

3.1 Residence and rates

Individuals are resident if they stay in Norway more than 183 days in any twelve-month period or more than 270 days over thirty-six months; residents are taxed on worldwide income, non-residents on Norwegian-source income. The dual system taxes 'general income' — all net income including employment, business, rental and capital income after deductions — at a flat 22% (reduced in the two northernmost counties), while a progressive bracket tax (trinnskatt) applies to gross salary, pension and business income in five steps: roughly 1.7% and 4.0% in the lower brackets, rising through 13.7% and 16.8% to 17.8% on income above approximately NOK 1.47 million. With employee social security of 7.6% on salary, the top marginal rate on employment income is approximately 47.4%. A standard minimum deduction (45–46% of salary up to about NOK 95,000) and a personal allowance reduce the general income base; a flat-rate PAYE scheme of 25% is available for most non-resident workers.

3.2 Capital income, dividends and wealth tax

Capital income of individuals — interest, rental income and most gains — is taxed as general income at 22%. Dividends and gains on shares are first reduced by a risk-free-return allowance (skjermingsfradrag) on the share's cost base, and the remainder is multiplied by an upward-adjustment factor of 1.72 before being taxed at 22%, giving an effective rate of 37.84%; the same treatment applies to distributions from partnerships. Individuals also pay net wealth tax on worldwide net assets: 1.0% on net wealth above NOK 1.9 million (double for couples), rising to 1.1% above NOK 21.5 million, with the municipal and state components combined; listed and unlisted shares and operating assets benefit from a 20% valuation discount, and primary dwellings are assessed at a fraction of market value. There is no inheritance or gift tax. An exit tax applies to unrealised share gains above NOK 3 million on emigration, payable in instalments over twelve years or deferred until realisation, and cancelled on return within the statutory window.

3.3 Social security and payroll

Employee national insurance contributions are 7.6% of gross salary (5.1% on pensions, 10.8% on self-employment income), with no ceiling. Employers pay regionally differentiated employer's social security contributions of 14.1% in central areas, stepping down to 0% in the far north; the temporary extra 5% charge on high salaries was abolished from 2025. Employers withhold tax monthly under the PAYE machinery and report electronically through the a-melding by the 5th of the following month, remitting withheld tax and employer contributions in six bi-monthly instalments. Benefits in kind are broadly taxable; company cars are taxed on a standardised percentage of list price.

3.4 Inbound individuals

Most non-resident and first-year foreign workers fall by default into the simplified PAYE scheme: a final flat 25% tax (including social security; 17.3% for those exempt from Norwegian social security) on gross employment income up to bracket-tax step 3, with no deductions and no filing obligation; workers may opt out into ordinary taxation. There is no general expatriate concession beyond this. Cross-border social security follows EEA coordination rules and totalisation agreements, and treaty relief applies to short-term postings. Foreign researchers and offshore workers face sector-specific rules, and the wealth tax makes pre-arrival planning relevant for high-net-worth inbound individuals, as worldwide net assets become taxable once residence is established.

Dividends distributed by Norwegian companies to non-resident shareholders attract 25% withholding tax. Corporate shareholders genuinely established and carrying on real economic activity within the EEA are exempt under the participation-exemption logic; treaty rates typically reduce the charge to 15% for portfolio holders and 0–5% for qualifying corporate shareholders. Norway levies no withholding tax on ordinary interest and royalties, except a 15% withholding on interest, royalties and lease payments for ships, rigs and other tangible assets paid to related parties (50% common ownership) resident in low-tax jurisdictions — waived where the recipient is genuinely established in the EEA. There is no withholding on service fees. Norway's treaty network of some 90 conventions incorporates the principal-purpose test through the multilateral instrument; dividends from petroleum special-tax income are exempt from withholding by statute.

Relief at source on dividends requires the shareholder to be pre-approved or documented through the withholding agent, with refund claims otherwise filed with the tax administration; EEA corporate shareholders must evidence genuine establishment (premises, staff, activity) to displace the statutory 25%. Because the interest and royalty withholding applies only to related parties in low-tax jurisdictions, most third-party financing and licensing flows leave Norway withholding-free, but group treasury and IP structures routed through low-tax hubs must be tested both for the 15% withholding and for NOKUS attribution.

5.1 General anti-abuse and hybrids

A statutory general anti-avoidance rule, codified in 2020 in section 13-2 of the Tax Act, allows the tax administration to disregard arrangements whose principal effect is a tax advantage contrary to the purpose of the rules, judged on objective indicators; a specific anti-avoidance rule (section 13-3) targets the exploitation of tax positions such as loss carryforwards. Norway is not bound by the EU anti-tax-avoidance directives but has adopted equivalent measures: the interest limitation, NOKUS (CFC) taxation, exit taxation and, from 2020, a hybrid-mismatch rule denying deductions for payments to related parties where hybridity produces deduction without inclusion. The participation exemption's substance requirement for EEA holdings and the low-tax-jurisdiction carve-outs function as switch-over protections.

5.2 Exit taxation and disclosure

Corporate exit tax applies at market value when assets or liabilities lose their connection to Norwegian taxation, including on migration of residence and transfers to foreign head offices, with instalment relief for EEA transfers. For individuals, the tightened exit tax on latent share gains above NOK 3 million requires payment within twelve years absent return. Norway participates in the OECD common reporting standard and exchanges country-by-country reports and rulings; DAC6-style EU mandatory disclosure does not apply, but reporting obligations attach to the controlled-transactions form, the shareholder register and the beneficial-ownership register. Treaty benefits are conditioned on the principal-purpose test, and the tax administration examines substance in intermediate holding companies before granting exemption or treaty relief on dividends.

6.1 VAT

VAT applies at a standard 25%, with a 15% rate on foodstuffs and a 12% rate on passenger transport, accommodation, cinema, museums and broadcasting; zero-rating covers exports, books and newspapers (including electronic), electric-vehicle supplies within limits, and international transport. Registration is compulsory once taxable supplies exceed NOK 50,000 in a twelve-month period; non-established suppliers of remote services and low-value goods to Norwegian consumers register under the simplified VOEC scheme. Returns are generally bi-monthly, due one month and ten days after the period (annual for small businesses), filed electronically direct from accounting systems on SAF-T standard data. Financial services and health, education and real estate are exempt without credit, with a voluntary registration option for commercial property letting; input VAT adjustment periods run ten years for real property.

6.2 Transaction, payroll and other taxes

There is no stamp duty on share transfers; transfers of real property attract a 2.5% document fee on registration of title. Employers bear the regionally differentiated employer's contribution (0–14.1%) and a 5% financial activities tax on payroll in the financial sector. Municipalities may levy property tax between 0.1% and 0.7% of assessed values. Excise duties are extensive — CO2 tax (rising towards the 2030 target), electricity, fuel, sugar-free beverages abolished but alcohol and tobacco heavily taxed — and a production tax applies to onshore wind (NOK 0.0237 per kWh, offsettable against resource rent tax) alongside the natural resource tax on hydropower (NOK 0.013 per kWh, creditable against corporate tax). There is no inheritance or gift tax; the net wealth tax applies to individuals only.

7.1 Filing, assessment and audit

The tax year is the calendar year; deviating financial years are permitted only in limited cases (e.g. branches of foreign companies with deviating years). Corporate tax returns are filed electronically via Altinn by 31 May of the year after the income year, with a one-month extension available on application; the system operates on self-assessment, with the taxpayer's return forming the assessment unless corrected. Companies pay advance tax in two instalments on 15 February and 15 April of the year following the income year, with any balance due three weeks after the tax settlement; petroleum companies pay in six instalments. The tax administration may reassess within five years of the income year, extended to ten years in cases of serious evasion; audits are risk-based and increasingly data-driven off SAF-T files, with the large-taxpayer and oil-taxation offices handling the biggest groups.

7.2 Rulings, appeals and penalties

Binding advance rulings (BFU) are available from the tax administration on the tax consequences of contemplated transactions, for a fee scaled to the taxpayer's size. Objections go first to the tax office and then to the independent Tax Appeal Board (Skatteklagenemnda); thereafter to the ordinary courts, with the district court, court of appeal and Supreme Court hearing tax cases — there is no specialised tax court. Mutual agreement procedures and, within the EEA relevant instruments, arbitration address double taxation. Additional tax of 20% applies to inaccurate or incomplete returns (40–60% in aggravated cases), with relief for excusable error and for voluntary correction before discovery; late-filing coercive fines accrue daily. Interest runs on underpaid tax from the due dates.

Additional advance payments can be made until 31 May to avoid interest on underpaid tax; refunds carry interest in the taxpayer's favour. The pre-filled personal return and the self-assessment corporate return both permit self-correction for up to three years after the filing deadline, which in practice resolves many disputes without formal objection.

9.1 Entity choice

The AS is the standard vehicle: minimum share capital of NOK 30,000, a board of directors, and full corporate tax status at 22%. The ASA suits listing and public offers (minimum capital NOK 1 million). Partnerships (ANS, DA, KS and the internal partnership IS) are transparent, with partners taxed at 22% on allocated profits and an upward-adjusted charge on distributions to individual partners. A Norwegian branch of a foreign company (NUF) is taxed on attributable profits at 22% with no remittance tax and lighter capital requirements, and is common for market entry; shipping groups weigh the tonnage tax election, which locks in for ten years.

9.2 Structuring and incentives

Holding structures benefit from the participation exemption on EEA shares and the absence of withholding on ordinary interest and royalties; the 3% dividend clawback disappears inside a more-than-90% tax group, which also unlocks group contributions and book-value asset transfers. Financing must be tested against the 25% EBITDA interest limitation (NOK 25 million group threshold), the equity escape, the 15% low-tax-jurisdiction withholding and NOKUS. R&D-intensive operations should secure SkatteFUNN approval before year-end to capture the 19% refundable credit, and location decisions can exploit the regionally differentiated employer contribution. Resource-sector investors must model the cash-flow-based resource rent taxes, whose immediate investment deduction materially improves post-tax economics despite headline marginal rates of 47–78%.

9.3 Worked effective-rate illustration

A Norwegian AS earns EBITDA of NOK 20,000,000, books depreciation of NOK 3,000,000 and net interest expense of NOK 2,000,000. As a stand-alone company below the NOK 5 million threshold, the interest is fully deductible. Taxable profit is 20,000,000 − 3,000,000 − 2,000,000 = NOK 15,000,000. CIT at 22% is NOK 3,300,000. Qualifying SkatteFUNN R&D costs of NOK 5,000,000 generate a 19% credit of NOK 950,000. The net corporate burden is 3,300,000 − 950,000 = NOK 2,350,000, an effective rate of 2,350,000 / 15,000,000 = 15.7% on taxable profit. If the after-tax profit were fully distributed to a resident individual (ignoring the risk-free-return allowance), the dividend would be taxed at 22% × 1.72 = 37.84%, giving a combined burden on distributed profits of roughly 22% + (78% × 37.84%) ≈ 51.5% before the credit effect.

9.4 Compliance

Expect fully electronic filing through Altinn, SAF-T standard accounting data on demand, bi-monthly VAT and payroll remittance cycles, statutory financial statements filed with the Register of Company Accounts, the controlled-transactions form and transfer pricing documentation above the thresholds in section 2.8, shareholder-register and beneficial-ownership filings, and — for large groups — Pillar Two registration, data collection and supplementary tax returns even where safe harbours reduce the top-up to zero. Resource-sector entities carry additional per-plant computations and reporting for the resource rent taxes.
