Tax Treaty Relief in Norway

Norway's double-tax treaty (DTT) network spans roughly 90 bilateral agreements concluded with countries across all inhabited continents. These conventions are administered by Skatteetaten -- the Norwegian Tax Administration -- and maintained by the Ministry of Finance (Finansdepartementet). Together with the multinational Nordic Tax Convention and the OECD Multilateral Instrument (MLI), they form the complete framework for eliminating or reducing double taxation on income and wealth earned across borders involving Norway.

How does Norway relieve double taxation -- credit or exemption?

Norway's primary method for relieving double taxation is the credit (fradragsmetoden): a resident taxpayer may deduct foreign tax actually paid against the Norwegian tax computed on the same income. The credit is capped at whichever is smaller -- the foreign tax paid or the Norwegian tax attributable to that income. Unused credits carry forward five years and may also be reversed to prior years if the taxpayer will not generate future foreign income. The credit applies separately per income category; a credit against income tax cannot reduce a wealth-tax liability, and vice versa. According to PwC's Norway Individual guide, older Norwegian treaties favoured the exemption method, but treaty policy shifted toward the credit method from around 2004 onward, and new treaties are now credit-based. A handful of residual exemption provisions survive in specific older agreements -- the Norway-Malaysia DTA, for example, retains the exemption method for certain salary income. Taxpayers claim relief by logging into their Skatteetaten profile and selecting the applicable method with supporting foreign-tax documentation. Documentation must be in a Nordic language or English.

How does the residence tie-breaker work?

Dual-residence conflicts -- when both Norway and another state claim full tax residency over the same individual -- are resolved through the treaty tie-breaker cascade prescribed in Article 4 of the OECD Model, which most Norwegian DTTs follow. Skatteetaten applies the following hierarchy: (1) permanent home -- the state where the individual has a permanent place of abode takes precedence; (2) centre of vital interests -- if both states have a permanent home, the decisive factor is where the individual holds the stronger personal and financial connections (location of family, employment, bank accounts, social ties); (3) habitual abode -- if vital interests cannot be determined, the state where the individual normally resides prevails; (4) nationality -- citizenship breaks remaining ties. The process results in a single state of treaty residence; the other state then taxes only the income assigned to it under the treaty's distributive rules. Taxpayers must present a Certificate of (Fiscal) Residence issued by the competent authority of the claimed residence state, confirming treaty-residence status for the specific year. This certificate can be uploaded directly through altinn.no.

What withholding rates apply to dividends under Norway's treaties?

Norway's domestic dividend withholding tax (kildeskatt) rate is 25% under section 10-13 of the Skatteloven. This rate is reduced -- often substantially -- under treaty or EEA rules. The table below shows representative treaty rates drawn from the Norwegian Ministry of Finance's published schedule (last updated June 2025):

Source: Norwegian Ministry of Finance, Treaty WHT Rates on Dividends (June 2025). The standard domestic rate without a treaty is 25%.

For corporate shareholders resident in an EEA state (Norway is an EEA member but not an EU member), the participation exemption (fritaksmetoden) under section 2-38 of the Skatteloven provides a 0% kildeskatt rate on dividends paid to a qualifying parent holding at least 10% of the Norwegian subsidiary, provided the parent is genuinely established and carries on genuine economic activity in its EEA state of residence. This mirrors the EU Parent-Subsidiary Directive as transposed via the EEA Joint Committee. Beneficial ownership must be demonstrable; conduit arrangements that lack economic substance do not qualify.

What are Norway's withholding rules on interest and royalties?

Norway does not impose a general withholding tax on interest or royalties paid to foreign non-residents. The standard rate on both is 0% under domestic law -- an important distinction from many peer OECD jurisdictions that apply 10-25% domestic rates before treaty reduction. However, since 2021 (effective for payments from 1 July 2021), a 15% withholding tax applies to interest, royalties, and certain leasing payments made by Norwegian entities to related parties resident in a low-tax jurisdiction, under sections 10-80 to 10-82 of the Skatteloven. Skatteetaten defines a low-tax jurisdiction as one where the general income tax on overall profits is less than two-thirds of the Norwegian corporate rate (22%), broadly equivalent to a sub-15% effective rate. A statutory list of jurisdictions deemed always low-tax is maintained by Skattedirektoratet. The 15% rate can be reduced or eliminated under bilateral treaties -- treaty rates of 0% or 5-10% apply where the relevant DTT covers interest and royalty income. The 15% WHT does not apply if the related-party recipient is genuinely established and carries on genuine economic activity in an EEA state, regardless of that state's corporate rate.

How does the Multilateral Instrument (MLI) modify Norwegian treaties?

Norway signed the OECD MLI on 7 June 2017, deposited the ratification instrument on 17 July 2019, and the MLI entered into force for Norway on 1 November 2019. Norway notified 28 of its bilateral DTTs as Covered Tax Agreements (CTAs), including treaties with Australia, Canada, China, India, Japan, Mexico, the Netherlands, and the United Kingdom. For each CTA, the MLI modifies the treaty to the extent the partner jurisdiction has made matching notifications under the same provision. Norway adopted the Principal Purpose Test (PPT) under Article 7 of the MLI as the minimum anti-avoidance standard. The PPT denies treaty benefits where obtaining that benefit was one of the principal purposes of an arrangement or transaction, unless granting the benefit would be consistent with the treaty's object and purpose. Norway also implemented the preamble statement under Article 6. The Ministry of Finance has published synthesised texts showing how the MLI applies in relation to each relevant Norwegian treaty; these texts are aids to interpretation and not themselves sources of law. Taxpayers relying on treaty benefits in MLI-covered arrangements should verify that their structure does not trigger the PPT.

How do NOKUS (CFC) rules interact with treaty relief?

Norway's NOKUS rules (Norskkontrollert Utenlandsk Selskap, sections 10-60 to 10-68 of the Skatteloven) impose current-year Norwegian taxation on the proportional share of income earned by a Norwegian-controlled foreign company resident in a low-tax jurisdiction. Control is established when Norwegian owners hold at least 50% of shares or capital at both the start and end of the income year. The low-tax threshold mirrors the interest/royalty WHT definition: effective tax below two-thirds of what the entity would owe if Norwegian-resident. An important exemption applies: companies resident in a DTT country are generally exempt from NOKUS taxation provided their income is not mainly passive in nature (i.e., largely interest, dividends, or royalties). As of mid-2025, the Norwegian government is reviewing whether to expand this exemption -- potentially including entities with mainly passive income in DTT countries -- or to restrict it, particularly in the context of Pillar Two implementation. The interaction matters for holding structures: a Norwegian-owned entity in a treaty jurisdiction with passive income may currently be caught by the mainly-passive carve-out even if the treaty would otherwise protect it.

Norway also imposes exit tax (utflyttingsskatt) when an individual resident moves abroad and holds shares or securities with unrealised gains exceeding NOK 3,000,000 (basic deduction as of 20 November 2024). The gains are computed as if disposed of the day before emigration. Payment may be deferred in instalments over 12 years. For moves to EEA states, losses are also taken into account; for moves outside the EEA, only gains are included. Where the departing taxpayer moves to a DTT country, treaty provisions on capital gains (typically aligned with OECD Model Article 13) govern which state retains taxing rights over any subsequent actual realisation -- but Norway's exit charge itself is triggered at the point of emigration, not at eventual sale, and bilateral treaties generally do not eliminate it for gains accrued during Norwegian residency.
