Did you know your employer also pays tax on your salary? It costs the employer $1,500 to pay you $50,000. In other words, every time you spend $10 of your hard-earned money, $2.04 goes to the government.

Real tax rate

19.8%

So, with you and the employer both paying tax, what used to be a 17.4% tax rate now rises to 19.8%, meaning your real tax rate is actually 2.4% higher than what it seemed at first.

Summary

If you make $50,000 a year living in New Zealand, you will be taxed $8,715. That means that your net pay will be $41,285 per year, or $3,440 per month. Your average tax rate is 17.4% and your marginal tax rate is 31.4%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of $100 in your salary will be taxed $31.4, hence, your net pay will only increase by $68.6.

Bonus Example

A $1,000 bonus will generate an extra $686 of net incomes. A $5,000 bonus will generate an extra $3,430 of net incomes.
