How to use Norway Income Tax Calculator
This Norway income tax calculator estimates what an employee pays under Norway’s distinctive two-layer system based on your annual income and the tax year you select. Choose between 2023, 2024, 2025 and 2026. Norway charges a flat 22% general income tax on income after the personal allowance (personfradrag) and minimum standard deduction (minstefradrag), and on top of that a progressive bracket tax (trinnskatt) of 1.7% to 17.8% on your gross personal income. The calculator merges both layers, adds the 7.7% national insurance (trygdeavgift), then shows your effective rate, marginal rate and a full bracket breakdown.
- Select your income year (2023, 2024, 2025, or 2026) from the dropdown.
- Enter your annual gross salary in Norwegian kroner (lønn before tax).
- Keep the filing status as Individual — Norway taxes individuals separately.
- Click Calculate to see your income tax, effective rate and marginal rate.
- Review the bracket-by-bracket breakdown and your estimated take-home after trygdeavgift.

How Norway’s two-layer tax system works
Norway is unusual in taxing income on two bases at once. First, general income (alminnelig inntekt) — your income after the personfradrag and minstefradrag — is taxed at a flat 22%. Second, a progressive bracket tax (trinnskatt) is charged on your gross personal income in five steps from 1.7% up to 17.8%. This calculator merges the two into a single combined-rate schedule applied to your gross salary, using a 0% allowance band (about NOK 200,550 in 2025) to stand in for the personfradrag and the capped minstefradrag. For example, on NOK 600,000 in 2025 the combined income tax is about NOK 100,714 — an effective rate near 16.8%, well below the 26% marginal rate.
| Annual personal income (NOK) | Combined marginal rate | How it is built |
|---|---|---|
| 0 – 200,550 | 0% | Allowance band (personfradrag + minstefradrag) |
| 200,550 – 226,100 | 22% | Flat general income tax only |
| 226,100 – 318,300 | 23.7% | 22% + 1.7% bracket tax (trinn 1) |
| 318,300 – 725,050 | 26.0% | 22% + 4.0% bracket tax (trinn 2) |
| 725,050 – 980,100 | 35.7% | 22% + 13.7% bracket tax (trinn 3) |
| 980,100 – 1,467,200 | 38.8% | 22% + 16.8% bracket tax (trinn 4) |
| Over 1,467,200 | 39.8% | 22% + 17.8% bracket tax (trinn 5) |
The personfradrag and minstefradrag
Two deductions shrink the base for the flat 22% tax. The personfradrag (personal allowance) is a flat basic deduction against all income — NOK 108,550 in 2025. The minstefradrag (minimum standard deduction) covers typical work expenses and is 46% of your salary, capped at NOK 92,000 in 2025. Because the minstefradrag is capped, anyone earning roughly NOK 200,000 or more gets the same fixed total allowance, so this calculator models the two together as a single 0% band of about NOK 200,550. That makes the result exact for typical full-time salaries and only slightly generous for low part-time incomes, where the minstefradrag has not yet reached its cap.
National insurance (trygdeavgift) and take-home pay
On top of income tax, an employee aged 17 to 69 pays national insurance (trygdeavgift) on personal income. The salary rate is 7.7% in 2025 and steps down to 7.6% in 2026 (it was 7.8% in 2024 and 7.9% in 2023). No contribution is due on income up to NOK 99,650, and in a narrow phase-in band just above that the contribution is capped at 25% of the excess; this calculator applies the flat rate once you pass the limit, which matches reality for normal full-time pay. Trygdeavgift is subtracted in your take-home figure but, unlike many countries, it does not reduce your income-tax base.
Effective versus marginal tax rate in Norway
Your effective tax rate is total income tax divided by income — your true average. Your combined marginal rate is the tax on your next krone, which in Norway is the flat 22% plus whichever trinnskatt step you are in. On NOK 600,000 in 2025 your marginal rate is 26% (22% + the 4% second step) but your effective income-tax rate is only about 16.8%, because the allowance band and the lower steps apply first. At NOK 1,000,000 the marginal rate climbs to 38.8% while the effective rate is around 23.2%. Knowing the gap helps you judge the real after-tax value of a bonus, overtime or a pay rise.
