Tax system

Understanding New Zealand taxes

The amount you keep can depend on several parts of the New Zealand tax and payroll system.

Income tax

Income tax is calculated using the tax brackets and rates that apply to your taxable income.

ACC levy

Certain employment income may be subject to a levy that helps fund the Accident Compensation Corporation scheme.

GST

Goods and Services Tax applies to many goods and services, although it is generally not part of a direct take-home pay calculation.

Retirement savings

KiwiSaver and long-term savings

KiwiSaver is a widely used long-term savings scheme in New Zealand. Contributions may come from the employee, employer and, where eligible, certain government contributions.

Employee contributions

Personal contributions are generally calculated as a percentage of eligible pay.

Employer contributions

Your employer may be required to make a minimum contribution depending on the applicable rules and your circumstances.

Long-term growth

Investment returns, fees, contribution levels and the investment horizon can significantly affect the future balance.
