Is eiendomsskatt (property tax) mandatory for all Norwegian homeowners?

No. Eiendomsskatt is an optional municipal charge; each of Norway's 357 municipalities decides whether to impose it. As of 2025, 325 municipalities levy it and 32 do not. Where it applies, the residential rate may not exceed 0.4% (4 promille) of the assessed taxable base. Many municipalities also offer a bunnfradrag exemption that reduces the taxable base by a fixed NOK amount per unit.

What is dokumentavgift and who must pay it?

Dokumentavgift is a one-time 2.5% transfer duty levied on the market value of a property when a freehold title deed is registered at Kartverket. The buyer pays it within 14 days of registration. A fixed registration fee of NOK 545 also applies. Purchases of borettslag (housing cooperative) shares are exempt because no freehold title deed changes hands, as are transfers between spouses and certain inheritances.

How does Norway's wealth tax treat primary versus secondary homes?

A primary dwelling (primærbolig -- the property where you are registered in the National Population Register) enters Norway's wealth-tax base at only 25% of its formula market value (up to NOK 10 million; 70% above that threshold). A secondary dwelling is valued at 100% of market value, with no discount. The difference is significant: an NOK 8 million primary home adds only NOK 2 million to the wealth-tax base.

Is there a national recurring property tax in Norway?

No. Norway does not impose any federal annual charge on property ownership. The only recurring property tax is eiendomsskatt, which is levied by individual municipalities at their discretion under Eiendomsskatteloven. Municipalities that do levy it may charge up to 0.4% per year on residential assessed value. Municipalities that choose not to levy it impose no annual property-ownership charge at all.

How is the eiendomsskatt taxable base calculated for a residential property?

Most municipalities using Skatteetaten's formula-based assessment set the taxable base at 70% of the calculated market value, then apply a mandatory minimum reduction of 30% to that figure. An optional bunnfradrag (basic exemption) may reduce the base further. Oslo uses 70% of assessed market value minus a NOK 4.9 million bunnfradrag before applying its 1.7 promille rate, meaning properties below roughly NOK 7.25 million often owe nothing.

Does Norway have a national property tax?

Norway has no federal recurring property tax on ownership. The national government does not levy an annual charge on real estate simply for owning it. The recurring tax that many homeowners in Norway do pay is eiendomsskatt (property tax under Eiendomsskatteloven), but this is a municipal-level charge that each kommune (municipality) decides independently whether to introduce. As Statistics Norway (SSB) confirmed for 2025, 325 of 357 Norwegian municipalities currently impose eiendomsskatt, while 32 do not levy it at all. [^1] The framework reflects the strong municipal-autonomy tradition in Norwegian governance: the Eiendomsskatteloven sets maximum rates and procedural floors, but the decision to collect belongs to each local council.

How does eiendomsskatt work, and what are the rates?

Where a municipality has voted to impose eiendomsskatt, the statutory rate range runs from 1 promille (0.1%) to 7 promille (0.7%) of the assessed taxable base. However, for residential and holiday properties the maximum is capped at 4 promille (0.4%) under Eiendomsskatteloven section 11 -- a protection phased in through 2020-2021 that reduced the prior residential ceiling from 5 promille and then 7 promille. [^2] Commercial property continues to be eligible for rates up to 7 promille.

A municipality introducing eiendomsskatt for the first time may not exceed 1 promille in year one, and may raise the rate by no more than 1 promille per year until reaching the allowed ceiling. This phase-in rule prevents sudden large increases in residential tax bills.

The taxable base for residential properties in municipalities using Skatteetaten's calculated market value is generally 70% of the formula market value, subject to a mandatory minimum reduction of 30% from the assessed value. [^2] Municipalities may also establish a bunnfradrag (basic exemption) -- a fixed NOK amount deducted from each residential unit's taxable base before the rate applies. Oslo, for example, set its bunnfradrag at NOK 4.9 million for 2026, which effectively shields lower-value dwellings from any tax at all. [^3] The average annual eiendomsskatt bill on houses across all taxing municipalities was approximately NOK 3,877 in 2025, according to SSB data. [^1]

Rate component	Residential & holiday	Other property
Minimum rate (any property)	0.1% (1 promille)	0.1% (1 promille)
Maximum rate	0.4% (4 promille)	0.7% (7 promille)
Year-1 ceiling if newly introduced	0.1%	0.1%
Maximum annual increase	0.1% per year	0.1% per year
Mandatory taxable-base reduction	At least 30%	At least 30%

What is dokumentavgift and when does it apply?

When you buy an existing freehold property in Norway and register the title deed (skjote) in the land register, dokumentavgift is due: a one-time transfer duty of 2.5% of the property's market value at the time of registration. [^4] The duty is administered by Kartverket (the Norwegian Mapping Authority) and an invoice is issued the same day registration is completed, with a 14-day payment deadline. There is no deferral or instalment arrangement available. A fixed registration fee (tinglysingsgebyr) of NOK 545 applies separately to the deed registration and is payable in addition to the 2.5% charge. [^5]

The 2.5% base is market value, not just the cash price. If you assume the seller's mortgage debt as part of payment, the full market value (cash price plus assumed debt) forms the base. Similarly, gifts of property are assessed on market value, not the notional gift amount.

A significant category of transactions is exempt from dokumentavgift: the purchase of a borettslag (housing cooperative) share. A borettslag transaction transfers a member share and an associated tenancy right to a specific unit -- it does not transfer freehold title to underlying real estate. Because no title deed changes hands, no tinglysing (land-register entry) triggers dokumentavgift. This exemption is practically important because borettslag tenure accounts for a substantial proportion of urban Norwegian housing stock, particularly in Oslo. [^4] Eierseksjon (condominium) and detached-home purchases are freehold transfers and therefore subject to the full 2.5%.

Additionally, transfers between spouses and certain inheritance scenarios qualify for exemption under the Dokumentavgiftsloven. [^4]

For a worked example: a buyer purchasing an Oslo eierseksjon apartment at NOK 6,000,000 would owe dokumentavgift of NOK 150,000 plus the NOK 545 registration fee -- a total of NOK 150,545 due within 14 days of registration.

How does Norwegian wealth tax (formuesskatt) treat property?

Norway is one of only a handful of developed countries that still levies a personal net-wealth tax (formuesskatt). For 2026, the combined municipal and state wealth tax rate is 1.0% on net assets between NOK 1.9 million and NOK 21.5 million, and 1.1% above NOK 21.5 million. The basic exemption threshold is NOK 1.9 million (doubled for jointly assessed spouses). [^6]

Property enters the wealth-tax base at discounted valuations:

Primary dwelling (primærbolig): 25% of the Skatteetaten formula market value on the portion up to NOK 10 million; 70% of any value exceeding NOK 10 million. The address in the National Population Register determines which property qualifies. [^7]
Secondary dwelling (sekundærbolig): 100% of market value -- no discount. This category covers investment property, rental flats, vacation homes, and any additional residences owned. [^7]

The primary-dwelling discount is substantial. A home with a formula market value of NOK 8 million enters the wealth-tax base at only NOK 2 million (NOK 8m x 25%). The same property held as a secondary dwelling would be valued at the full NOK 8 million. A new machine-learning-based national valuation model is being introduced from 2026 onwards that is expected to raise assessed market values closer to actual transaction prices, particularly for high-value urban properties. [^6]

For property owners who also pay eiendomsskatt to their municipality, there is no formal deduction of eiendomsskatt against the wealth-tax base -- the two taxes are assessed independently. Owners can however deduct mortgage debt against the wealth-tax base in proportion to asset valuations, which partially offsets the wealth-tax burden on leveraged property.

Taxation at both the eiendomsskatt (municipal) and formuesskatt (national) level makes it important for property owners in Norway to understand how both layers interact. Property held as a secondary investment is particularly affected, as it attracts the full 100% wealth-tax valuation and is subject to eiendomsskatt with no bunnfradrag relief in many municipalities. A qualified tax professional familiar with Norwegian property rules can help you calculate the combined annual liability and assess holding-structure options. See the Norway country overview for the broader Norwegian tax landscape.

Cross-border situations -- for instance, a Norwegian resident owning property abroad, or a foreign resident owning Norwegian property -- involve the applicable double-tax treaty and should be reviewed with a qualified tax professional before any purchase or disposal decision is made.
