Norway Income Tax Calculator
Work out roughly how much tax you pay on your salary income in Norway — National Insurance contribution, bracket tax and tax on ordinary income — and see what you're left with net.
How to use the income tax calculator
- Enter your gross annual salary — what you earn before tax.
- Add other deductions you're entitled to (union dues, commute deduction, etc.), if applicable.
- The calculator shows estimated net salary, total tax and effective tax rate.
How the tax is calculated
Tax on salary in Norway consists of three parts added together:
Worked example: a gross salary of 550,000 kr produces roughly 127,383 kr in total tax and 422,617 kr net. The effective tax rate is 127,383 ÷ 550,000 = 23.2 %. That is not the same as the marginal rate: the next krone you earn is taxed at around 34 %, because bracket tax is progressive while deductions are fixed. The effective rate tells you what you pay on average, the marginal rate what a pay rise actually yields.
The National Insurance contribution is calculated at 7.6 % of salary income (with a reduction rule for low incomes). Bracket tax is a progressive tax that increases in rate the more you earn, calculated on your gross income in brackets. Tax on ordinary income is 22 % of your income after the standard deduction and personal allowance have been subtracted.
A common misconception is that there's a single "tax rate" that applies to everyone. In practice, your effective tax rate is a blend of a flat rate on ordinary income and a progressive bracket tax — the more you earn, the higher your average rate climbs, even though no single krone is suddenly taxed much harder. That's why two people with different salaries can have quite different effective tax rates even though both are "ordinary employees".
This calculator estimates tax on salary income. If you're self-employed or run a sole proprietorship (enkeltpersonforetak), different rules apply — including a higher National Insurance rate and a different deduction structure — and the result here won't be accurate for you.
Frequently asked questions
What is bracket tax?
Bracket tax is an extra tax applied to your gross income above certain thresholds (brackets). The higher your income, the higher the rate you pay on the portion of income that exceeds each bracket.
Why do I pay a National Insurance contribution?
The National Insurance contribution funds Norway's National Insurance scheme, which covers, among other things, sick pay, parental benefit, work assessment allowance and retirement pension.
Is this the exact tax I have to pay?
No. This is a simplified estimate. Your actual tax depends on municipality, all your deductions, any wealth and other income. Use your tax return or skatteetaten.no for an exact figure.
Why is the tax rate on my payslip different from what I get here?
The withholding your employer deducts each month is based on your tax card (skattekort), which is itself an estimate the Norwegian Tax Administration calculates from last year's income and any changes you've reported. Your actual tax is only finalized in the annual tax settlement (skatteoppgjør) the following year, based on what you actually earned. This calculator shows an estimate based on your annual income, not the ongoing withholding.
Do I pay the same tax if I'm self-employed?
No. Self-employed individuals pay a higher National Insurance contribution rate than employees, and have a different deduction structure (including no standard deduction in the same way). This calculator is built for ordinary salary income and won't give an accurate estimate for business income.
