IRD number - individuals
Your IRD number is used for all your tax, entitlements and personal details that Inland Revenue holds.
What's on this page
You'll need an IRD number if you:
- earn income from any source (including a job, benefit, pension or investments)
- join KiwiSaver
- apply for a student loan, child support or Working for Families Tax Credits
- file tax returns
- buy, sell or transfer New Zealand property
- are starting up as self-employed.
If you don't have an IRD number, your employer will deduct income tax at the highest non-declaration tax rate of 45%. You should also check with your bank about the rate they charge on tax.
If you're a New Zealand citizen or New Zealand passport holder, you can apply for an IRD number for yourself, or a child in your care by completing our IRD number application - resident individual (IR595) form.
You can also use the Department of Internal Affairs' SmartStart service to register the birth of your child and apply for an IRD number at the same time. Just select the "Register birth online" service.
You can apply for your IRD number online after you arrive in New Zealand.
If you're an Australian passport holder
You can only apply for an IRD number for yourself. You'll need your passport details.

Go to our Proof of a fully functional NZ bank account (IR984) guide for more information.
If you don't have a bank account, you'll need to have completed customer due diligence. You can do this by completing our IRD number application - customer due dilligence (IR997) form.
If you're a RSE visa holder
We work with Immigration New Zealand on your behalf to register you.
If you're residing offshore you can only register online if you've already travelled to New Zealand and been verified by New Zealand Customs Service. If you don't have Customs verification you'll need to complete an IRD number application - non-resident/offshore individual (IR742) form.
Depending on your situation, the form will let you know what documents you need and what to do next. It'll also let you know if you need:
- a fully functional bank account. Our Proof of a fully functional NZ bank account (IR984) guide has more information, or
- completed customer due diligence if you don't have a bank account. You can do this by completing our IRD number application - customer due dilligence (IR997) form.
If you can't apply for an IRD number online, use our paper forms.
