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.

There is no cost when you apply for an IRD number with us. Please select the option below that best applies to your situation. 

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.
