Apply for an IRD number

If you're applying for an IRD number for an estate, choose the 'Trust' organisation type. Then you can select that it's an estate.

What happens next

  • We'll contact you if we need more information about your registration.
  • We'll email or post your IRD number to you. It can take 20 working days to arrive if you choose to have it posted.

My responsibilities

  • Keep your IRD number where you can easily find it.
  • Set up a myIR account for your business or organisation when you have your IRD number.
  • Tell us about any changes. The easiest way to update your details is in myIR. You can also send us a message in myIR and attach any required documents to it.
