An IRD or tax number is a unique number that we give you. You keep the same IRD number for life. It identifies you for all tax-related events in your life.
You need an IRD number if you:
- earn any money, for example from a job, benefit, bank account, investment or rental property
- open a bank account or invest money
- join KiwiSaver
- apply for Working for Families
- apply for child support
- apply for a student loan.
If you do not have an IRD number when you start earning money or interest you’ll pay a higher rate of tax.
It’s a good idea to get an IRD number even if you do not need it just yet.
