The Norway Income Tax Calculator estimates the tax on your salary and the net pay you take home. Norway combines a flat tax on ordinary income with a progressive step tax (trinnskatt) and a national insurance contribution, so the headline marginal rate rises steadily with income.
How it works
The estimate is built from three components:
- Flat tax on ordinary income — 22% applied to your income after subtracting the personal allowance (personfradrag).
- Trinnskatt (step tax) — a surcharge with five rising marginal rates. Each tranche of income above a threshold is taxed at that tranche’s rate, just like a bracket system.
- Trygdeavgift (national insurance) — 7.8% on your gross personal income.
Total tax is the sum of all three, and net pay is gross − total tax.
Example
On a gross income of 600,000 NOK: the 22% flat tax applies after the personal allowance, the trinnskatt adds its rising surcharge across the lower brackets, and the 7.8% national insurance is charged on the whole amount. Together these produce an effective rate noticeably below the top marginal rate, because only the highest tranche is taxed at the steepest step rate.
Notes
This is an orientation estimate using illustrative 2024 thresholds. It models only the personal allowance, not the minimum standard deduction or other reliefs, so a real assessment may differ. Confirm with Skatteetaten. All calculation happens locally in your browser.
