Who needs an IRD number?
You need an IRD number for any tax related obligations you have or entitlements you get. Common examples of when you need an IRD number include:
- earning income, for example from a job, benefit or investment
- opening a bank account
- joining KiwiSaver
- applying for Working for Families, child support or a student loan
- buying, selling or transferring property in New Zealand.
It’s a good idea to get an IRD number even if you do not need one yet.
You can get an IRD number for your baby when you register their birth.
If you do not have an IRD number when you start earning income, you'll pay a higher tax rate of 45%.
