Osloculture & etiquette

Before Skatteetaten will issue a national identity number or a D-number it requires an in-person identity check at one of a limited set of tax offices, and appointments in Oslo are booked out weeks ahead. Everything downstream — a bank account, BankID, a tax card, a fastlege, a phone contract — waits behind that number. Book the appointment the moment you know your arrival date, before you have an address, before you have anything. It is the single highest-leverage thing you can do about a Norwegian relocation.

If you are staying in Norway for six months or more you report a move and are entered in the National Population Register with a fødselsnummer. Under six months you get a D-number instead. The D-number works for pay and tax but it is treated as provisional by banks, landlords, insurers and some health services, and getting BankID on one is harder. If your stay is genuinely long-term, make sure the registration reflects that rather than defaulting to the temporary route because it looked faster.

Around four in five Norwegian households own their home, and the rental stock is disproportionately made up of individual owners letting a flat rather than professional landlords. That produces thin supply, short and variable tenancies, and viewings where twenty people appear at once. Deposits are legally capped at six months' rent and must go into a dedicated depositumskonto in your name that neither party can touch alone. If a landlord asks for the deposit into their ordinary account, that is unlawful and it is the clearest warning sign in the Norwegian market.

Most foreign workers are placed automatically into the PAYE scheme (kildeskatt på lønn) for short stays and for their first year of residence: a flat 25% of gross salary, or 17.4% in 2026 if you are exempt from Norwegian national insurance, with no deductions and no tax return at all. It is capped — you cannot earn more than NOK 725,050 in 2026 and stay in it. The scheme is voluntary and you may opt out into ordinary taxation, which is worth doing if you have substantial deductible costs such as mortgage interest or a long commute. Very few people run the comparison.

Norway is one of the few remaining countries with an annual wealth tax on individuals. It is charged at roughly one per cent of net assets above a threshold, rising slightly above a much higher one, and for a Norwegian tax resident it applies to worldwide assets — property abroad, foreign investment accounts, business holdings. Thresholds and rates are set in the annual budget and change. Anyone arriving with meaningful assets should get advice before becoming tax resident rather than after, because valuation rules and the treatment of unlisted shares and property differ substantially from income tax logic.

Restaurant meals, alcohol, taxis and services cost more here than anywhere else in the region, and alcohol is sold above 4.7% only through the state monopoly at limited hours. What offsets it is that the thing Oslo is actually for costs nothing: the Marka forest begins where the metro line ends, the fjord islands are on an ordinary public transport ticket, and allemannsretten gives you a legal right to walk, ski and camp across almost all uncultivated land. People who spend their weekends in restaurants find Oslo punishing; people who spend them outdoors find it cheap.
