Income Tax Calculator

The MyBudget Income Tax Calculator estimates your New Zealand income tax and take-home pay based on the income details you enter. Simply enter your gross or net income, choose how often you’re paid, and the calculator estimates your gross income, income tax and net income annually, monthly, fortnightly and weekly to help you better understand your earnings.

Gross income is the amount you earn before New Zealand income tax is deducted, while net income is the amount you receive after tax. Understanding the difference helps New Zealanders see how much money is available for everyday expenses, bills, debt repayments and savings, making it easier to build and manage a realistic budget.

The Income Tax Calculator provides an estimate, so your actual take-home pay may be different. Your final pay can vary depending on your tax code, KiwiSaver contributions, student loan repayments, ACC earners’ levy and other payroll deductions. Use the calculator as a guide rather than an exact payroll calculation.

The Income Tax Calculator may not include deductions such as KiwiSaver contributions or student loan repayments. These and other payroll deductions can affect your take-home pay, so your actual income may differ from the estimate. For information specific to your circumstances, check your payslip or visit Inland Revenue (IRD).

An Income Tax Calculator helps you estimate how much income you’ll have available after tax, making it easier to plan your budget. Once you know your estimated take-home pay, you can better manage bills, everyday expenses, debt repayments and savings goals. MyBudget builds on this with a personalised budget and a clear 12-month financial projection to help New Zealanders plan ahead with confidence.
