You keep the same IRD number for life so even if you lose it you do not need to apply for a new one. It’s easy to find your IRD number again.
You can find your IRD number:
- in myIR or My KiwiSaver
- on payslips
- on letters or statements you've received from us
- on your KiwiSaver statement
- on income details from your employer
- by calling us.
