What is the Norwegian corporate tax rate for 2026?

Most Norwegian companies pay a 22% corporate income tax (selskapsskatt) on taxable profit. There are no graduated brackets — the 22% rate applies to the full taxable amount.

How is the petroleum sector taxed differently?

Upstream petroleum income is subject to ordinary 22% corporate tax and a formal 71.8% special tax. A calculated corporate tax is deducted from the special-tax base, making the special tax about 56% of original income and the combined marginal rate 78%.

What is the financial activity tax (finansskatt)?

The finansskatt is an additional 5% tax on the payroll of financial services companies. It is a payroll tax, not a profit tax, so it is not included in this corporate income tax calculator. Affected companies should add this separately.

Are Norwegian companies taxed on worldwide income?

Yes. Norwegian resident companies are subject to corporate tax on their worldwide income. Foreign income may be offset by foreign tax credits or exemptions under Norway's participation exemption (fritaksmetoden) for qualifying dividends and capital gains.

Does this calculator include the participation exemption?

No. The calculator applies the standard 22% (or 78% for petroleum) rate to the full taxable income entered. The fritaksmetoden, interest limitation rules, and other adjustments require separate analysis by a Norwegian tax advisor.

What currency does Norway use for tax reporting?

Corporate tax returns are filed in Norwegian Krone (NOK). Use the NOK input field and convert from foreign currencies at the relevant exchange rate before entering.
