An IRD number is an eight or nine digit number unique to you. It is important as all your tax, entitlement and personal details are linked to this number.
Tax rates are different for individuals and companies. Rates can also change if legislation changes.
You can pay your tax, child support or KiwiSaver contributions electronically or by post.
We need your correct details so we can give you information. You can change your address, phone number and email details quickly and easily, through Secure online services.
You can also change your address and phone number through the New Zealand Post website Change My Address service and give your new details to other organisations at the same time.
If you think you’ll have difficulty meeting any of your tax obligations, contact us to discuss your situation. Penalties may apply if you don’t pay on time.
We publish different exchange rates for different purposes. This page explains which rates to use.
We’re committed to giving you good service. If you’re unhappy with the service you received please tell us. We’ll work with you to resolve any issues and improve our service. If you disagree with an assessment of tax or child support, you may need to follow the disputes process.
Normally, we can’t discuss your Inland Revenue records with anyone except you. But, you can choose to authorise someone else to act on your behalf, to help you with your tax. However, Child Support customers must authorise us in writing to release information to another person. An authorised person can discuss your child support, but can’t authorise forms or take other actions on your behalf.
We audit businesses to check if people are paying the correct amount of tax. The audit can cover income tax, GST and employer returns. After an audit you may be entitled to a refund or have tax to pay.
