NZ Tax & PAYE Calculators

Work out exactly what you owe — or are owed — under New Zealand tax rules. Calculate PAYE income tax and take-home pay, add or remove 15% GST, estimate a year-end refund, and handle the trickier cases: bonuses, secondary income, schedular payments and student loan repayments.

These tools use the current Inland Revenue PAYE brackets, the ACC earner levy and the standard 15% GST rate, and they run in your browser for privacy.

Frequently asked questions

How do I calculate my take-home pay in NZ?
Use the Income Tax or Take-Home Pay calculator — enter your gross salary and it deducts PAYE, the ACC earner levy and any KiwiSaver or student loan to show your net pay.
How do I work out GST?
Use the GST Calculator. To add GST, multiply the net price by 1.15. To extract GST from a gross price, multiply by 3 and divide by 23.
