What is an IRD number?

Your IRD number keeps track of the tax you pay and helps make sure you pay the right amount.

Your IRD number identifies you for all the tax-related events in your life. Your number is unique to you.

We collect tax for the government to use on services for New Zealanders. We collect tax from you if you earn income of any sort.

Who needs one?

You need an IRD number for any tax-related obligations you have or entitlements you receive. 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 don’t need one yet.

You can get an IRD number for your baby when you register their birth.

If you don’t have an IRD number when you start earning income you will pay a higher rate of tax of 45%.

Does my child need an IRD number?

Your child will need an IRD number if they:

  • earn income from any source
  • get interest from a bank account or investment
  • are included in your application for Working for Families or child support.

Keep it safe

Keep your IRD number where you can easily find it. You will need it for all tax-related events in your life.

If you lose your number we can help you find it.
