National Insurance Contribution
If you make 225,000 kr a year living in Norway, you will be taxed 35,722 kr. That means that your net pay will be 189,278 kr per year, or 15,773 kr per month. Your average tax rate is 15.9% and your marginal tax rate is 27.7%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of 100 kr in your salary will be taxed 27.67 kr, hence, your net pay will only increase by 72.33 kr.
A 1,000 kr bonus will generate an extra 723 kr of net incomes. A 5,000 kr bonus will generate an extra 3,617 kr of net incomes.
