Inheritance Tax Norway: What Heirs Actually Pay in 2026

Norway abolished its inheritance tax (arveavgift) completely in 2014. There is no inheritance tax, estate tax, or death duty in Norway in 2026.

But that doesn't mean inheriting assets is entirely tax-free. Norway's tax continuity principle creates a hidden liability that catches many heirs off guard.

The Tax Continuity Trap

Under Norwegian law, heirs inherit the deceased's original cost basis (skattemessig kontinuitet) for assets. When you eventually sell an inherited property or investment, you pay capital gains tax based on the gain accumulated since the deceased originally bought it — not since the date of death.

Example: Your parent bought a cabin in 1995 for NOK 500,000. It's worth NOK 3,000,000 when they die. If you sell it, you owe capital gains tax on the NOK 2,500,000 gain — the entire appreciation since 1995.

The one exception: if the deceased could have sold the property tax-free at the time of death (by meeting the 12-of-24-months primary residence rule), you receive a "stepped-up" basis equal to the market value at death. This effectively wipes out the historical capital gains liability.

How Norwegian Inheritance Law Divides Assets

The Inheritance Act (Arveloven) divides heirs into three classes. A living heir in a higher class completely excludes lower-class heirs from intestate succession:

• Class 1: Direct descendants — children, grandchildren
• Class 2: Parents, siblings, nieces, nephews
• Class 3: Grandparents, aunts, uncles, cousins

If the deceased was married, the surviving spouse is entitled to 25% of the estate, with a guaranteed minimum of 4G (four times the National Insurance Basic Amount, approximately NOK 538,000 in 2026). The children share the remaining 75%.

The Forced Share Rule (Pliktdel)

Norwegian law protects children's inheritance rights through forced shares. Two-thirds of the estate is reserved for the deceased's children, and this cannot be overridden by a will. The forced share is capped at 15G per child (roughly NOK 2 million), so for large estates the testator has more freedom.

This means you cannot disinherit your children in Norway — the forced share guarantees each child a statutory minimum.

Stepchildren and the Uskifte Veto

If the deceased had children from a previous relationship (særkullsbarn), these stepchildren hold significant power. A surviving spouse cannot enter an undivided estate (uskifte) without their written consent.

Stepchildren can refuse consent and demand their full statutory inheritance immediately. This often forces the surviving spouse to sell the family home to pay out the stepchildren's shares. Stepchildren can also negotiate conditional consent — for example, requiring that their inheritance share remain fixed or that they receive a partial payout upfront.

Unmarried Partners Have Almost No Rights

Norwegian law draws a sharp line between married spouses and unmarried cohabitants (samboere):

• With joint children: Entitled to a minimum inheritance of 4G and a limited right to undivided estate (restricted to the shared home, household goods, vehicle, and recreational properties)
• Without joint children: Zero statutory inheritance rights, regardless of how long you've lived together. Without a will, all assets pass to the deceased's biological family

An unmarried partner without joint children can be legally evicted from a shared home if the deceased owned it. The only protection is a will, which must be properly witnessed and can still only allocate assets above the forced share.

What Foreign Heirs Should Know

If you're inheriting from someone in Norway, the tax continuity principle applies regardless of where you live. Cross-border tax situations — especially for dual citizens or heirs in countries with their own estate taxes — require careful analysis to avoid double taxation.
