Capital gains tax in Norway Confirm the cited source.

Norway taxes capital gains as ordinary income (alminnelig inntekt) at a flat 22% rate. That headline figure applies to real estate, bonds, cryptocurrencies, and most other assets. The major exception is shares and equity funds, where an additional mechanism -- the aksjonærmodellen (Shareholder Model) -- pushes the effective rate to 37.84% in 2025 [1]. Understanding how the two figures relate, and what deductions reduce them, is the core of Norwegian capital-gains literacy.

01What is the 37.84% effective rate on shares, and why does it exist?

When an individual resident sells shares or redeems units in an equity mutual fund, the taxable gain is not simply the difference between sale price and purchase price. Instead, Skatteetaten multiplies that gain by the oppjusteringsfaktor of 1.72 before applying the 22% ordinary income rate. The arithmetic is straightforward: 1.72 x 22% = 37.84%. Skatteetaten performs the multiplication automatically inside your tax return; you see the adjustment as a separate line item [1]. The same factor applies to dividends received by individual shareholders. The factor was introduced to align the combined individual-plus-corporate tax burden more closely with the top marginal rate on wages, and was raised progressively from 1.15 (2016) to its current 1.72.

One practical consequence: a NOK 100,000 gross share gain produces NOK 172,000 of assessed income (NOK 100,000 actual + NOK 72,000 adjustment), taxed at 22% = NOK 37,840 in tax -- exactly 37.84% of the original gain [1]. The same factor applies to gains on share savings accounts (aksjesparekonto, ASK) when funds are withdrawn, and to units in funds whose equity content exceeds 80% of assets (share funds, aksjefond) [2].

02How does the skjermingsfradrag (shielding deduction) reduce the taxable gain?

Before the oppjusteringsfaktor is applied, shareholders may subtract the skjermingsfradrag -- a deduction designed to shelter the "normal" normative return on invested capital from tax [3]. The deduction for a given year equals the share's input value (purchase price plus acquisition costs) multiplied by the annual skjermingsrente (shielding interest rate). For 2025, Skatteetaten set the skjermingsrente at 3.6%, derived from the average observed yield on three-month Norwegian Treasury bills (4.148% for 2025), reduced by the 22% income tax rate and rounded [4].

Unused shielding deductions carry forward to future years and accumulate on top of the existing input value, so long-held shares build up a meaningful deduction balance. For a shareholder who paid NOK 500,000 for shares held for three years with no dividends, the accumulated deduction would be approximately NOK 500,000 x 3.6% x 3 = NOK 54,000. If that investor then realises a NOK 200,000 gain, only NOK 146,000 (NOK 200,000 - NOK 54,000) is subject to the 1.72 adjustment and the 22% rate, cutting the effective tax burden materially below 37.84%. Skatteetaten pre-populates the shielding deduction in the skattemelding for listed Norwegian shares; non-Norwegian shares require manual entry [3].

03When is a primary-residence gain fully exempt?

Norway provides a full exemption from capital gains tax on the sale of a primary residence (bolig) when two conditions are both satisfied: the seller must have owned the property for more than one year, and must have used it as their own residence for at least one of the two years immediately before the sale [5]. Meeting both tests eliminates the entire gain from income -- no 22% rate applies. There is no partial relief; the exemption is binary.

The one-of-two-years occupancy window allows considerable flexibility. A seller who lived in the property throughout year one but worked abroad during year two can still qualify if the one-year occupancy requirement is met across the combined 24-month look-back period. Investment properties, rental properties, and vacant land do not qualify and face the standard 22% rate on any taxable gain [5].

Holiday homes (fritidsboliger) carry a parallel but stricter exemption: the owner must have owned the property for more than five years and used it as their own holiday property for at least five of the last eight years before the sale. The longer threshold reflects the higher commercial-use risk associated with second properties [5].

04How are other real-estate gains taxed?

Any property sale that does not qualify for the primary-residence or holiday-home exemption produces a taxable gain treated as ordinary income at 22% [5]. This category includes residential rental property, commercial real estate, and building plots. The gain is calculated as sale proceeds minus the original purchase price plus documented capital improvements (forbedringskostnader). Losses on non-exempt property disposals are deductible against other ordinary income at the same 22% rate. There is no indexation or inflation adjustment in the gain calculation; the full nominal gain is taxable [5].

05What is the exit tax on emigration?

When a Norwegian tax resident emigrates -- becoming tax-resident in another country under an applicable tax treaty -- Norway treats the latent (unrealised) gains on shares and other qualifying financial assets as if they were realised on the day before departure. This deemed-realisation charge is called the exitskatt (exit tax) [6]. A basic deduction of NOK 3,000,000 applies: only the net latent gain exceeding 3 million NOK triggers an assessment, a threshold raised significantly by amendments effective for moves on or after 20 March 2025 (the previous threshold was NOK 500,000) [6].

The exit tax does not require immediate cash payment. Taxpayers may defer the full liability for up to 12 years, pay in annual instalments over 12 years, or pay immediately. Security may be required for deferral unless moving within the EEA. If the emigrant returns to full Norwegian tax residency within the deferral window, the exit tax liability is extinguished. Gains on assets accumulated during Norwegian residency are measured for exit-tax purposes; value growth occurring after emigration is not retrospectively taxed by Norway [6]. Real estate physically located in Norway remains subject to ordinary Norwegian taxation on any future disposal even after emigration and is not captured by the exit-tax mechanism.

For residents considering emigration, consulting a qualified tax professional well in advance of the move is strongly recommended. Rules changed materially in 2024-2025, and individual circumstances -- including treaty position, asset composition, and timing of share disposals -- significantly affect the liability.

Norway's capital gains rules touch nearly every aspect of personal finance, from the share-savings wrapper (aksjesparekonto) that defers tax on listed-equity disposals, to the interaction between the shielding deduction and multi-year holding periods. The Norway country overview provides context on Norway's broader tax framework. For jurisdiction-specific guidance calibrated to your own portfolio and residency situation, working with a qualified tax professional familiar with Norwegian law and any applicable tax treaty is the appropriate next step.
