How do I find my IRD number?

We may hold your IRD number so that we can process your Resident Withholding Tax, but it's probably better to contact the Inland Revenue directly on 0800 377 774 or use Inland Revenue's website.

To view your IRD number, log in to Westpac One® digital banking then go to Profile and choose Tax Details.
