Before moving to Norway, establish when Norwegian tax residence may begin and which income and assets need to be reviewed. This is particularly useful for business owners, investors and professionals who will retain financial interests in another country.
The assessment should use your actual travel plans, family circumstances and financial arrangements. A residence permit, a Norwegian address and tax residence answer different questions.
Count your days using the correct periods
Under Norwegian domestic rules, you become tax resident if you spend more than 183 days in Norway during a 12-month period, or more than 270 days during a 36-month period. Whole and partial days count. The days do not have to be consecutive.
The starting date also matters. If you exceed 183 days in the calendar year you arrive, residence generally begins on your first day of presence. If the qualifying stay spans two income years, residence starts on 1 January of the second year. Under the 270-day test, it starts on 1 January of the year the threshold is exceeded.
Keep a dated record of visits, including trips made before the planned relocation. Do not treat the thresholds as separate annual allowances or assume that leaving for a short trip restarts the count.
Review foreign income and assets
Norwegian tax residence generally brings worldwide income and wealth within the Norwegian tax assessment, subject to applicable treaty provisions and other rules. Keeping an investment, bank account or property abroad does not itself place it outside that assessment.
Prepare a financial inventory before the move. It should include employment and business income, pensions, bank and investment accounts, shares in private companies, property, debt and any other arrangements that require individual analysis. For company interests, retain ownership records and the accounts needed to examine valuation.
This is a planning exercise, not an assumption that every asset will receive the same treatment. Identify the relevant tax year, the type of asset or income and the rules in both countries before making decisions about a sale, distribution or restructuring.
Check whether a tax treaty changes the result
A person may be resident under the domestic rules of two countries at the same time. An applicable tax treaty may resolve that conflict by reference to factors such as available homes, personal and economic connections and habitual residence. The wording of the particular treaty must be checked.
Treaty residence and the taxation of each income category are separate parts of the analysis. Some treaties do not cover wealth taxes, so an income-tax conclusion should not automatically be applied to wealth. Obtain the documents needed to support any treaty claim, including a residence certificate where required.
Coordinate salary, incentives and business ownership
If you will continue working for an overseas employer or managing a foreign business, explain where the work will actually be performed and where decisions will be made. Ask advisers to identify the payroll, social-security and company-tax questions that need separate analysis.
For bonuses, options or other deferred remuneration, collect the plan documents, grant dates, vesting conditions and relevant work history. The payment date alone may not give the adviser enough information to assess the position.
Before transferring shares, paying a dividend or selling an investment around the move, compare the consequences in both jurisdictions. The purpose is to understand the transaction and its timing, rather than relying on a general assumption that an action before arrival will be tax-free.
Prepare for the first Norwegian tax return
Check foreign information carefully when reviewing the return. Foreign digital-bank accounts and payment services may not be pre-filled. Keep statements showing balances, income and transactions for the relevant reporting period, together with supporting records for foreign property and investments.
Where the same income or wealth is taxed in more than one country, the relevant relief generally has to be claimed correctly. The Norwegian Tax Administration requires supporting evidence of foreign tax assessed and paid when a credit is claimed. Preserve final assessments and payment records rather than relying only on estimated deductions.
